Background: Despite the widespread use of antibiotics, acute mastoiditis (AM) and related complications resulting from acute purulent otitis media continue to occur, predominantly in children. Although numerous studies have focused on the pathogenesis, aetiological agents, and treatment of AM, comprehensive investigations of the long-term outcomes of AM and the physiological consequences of surgical intervention in the temporal bone are lacking. Methods: Thirty patients who had undergone mastoidectomy for acute mastoiditis at a median age of 2.12 years were invited for evaluation at least five years postoperatively. The assessment included the Chronic Otitis Media Questionnaire 12, clinical examination with otomicroscopy, extended high-frequency pure-tone audiometry, distortion product otoacoustic emissions, middle ear impedance testing, and a newly developed protocol for noninvasive mastoid function measurement. Results were compared with a control group of 30 ears and with a group of 30 ears treated solely with tympanostomy for acute otitis media at risk of mastoiditis. Results: Although mean Chronic Otitis Media Questionnaire 12 scores were below 1 point, patients who had undergone mastoidectomy reported slightly greater difficulties with hearing in both quiet and noisy environments, along with an increased perception of tinnitus and unpleasant sensations around the ear. Otomicroscopy revealed minor structural changes in the test groups, which were absent from the control group. Pure-tone audiometry demonstrated approximately 10 dB higher thresholds at high and extended high frequencies, with similar findings observed in the distortion product otoacoustic emissions. Middle ear impedance testing indicated elevated stapedius reflex thresholds in the mastoidectomy group, while other parameters showed no statistically significant differences. Mastoid function testing demonstrated preserved pressure-buffering capacity but reduced thermal insulation of the vestibular organ under extreme thermal stimulation—an occurrence rarely encountered in daily life. Conclusions: In the long term, most patients recovering from acute mastoiditis exhibit only minor functional and structural sequelae, and the impact of mastoidectomy appears negligible compared with less invasive surgical interventions.

Objective: Children with cleft lip and/or palate (CLP) commonly present with otitis media with effusion (OME), with increased referrals for newborn hearing screening (NHS). Auditory brainstem response (ABR) testing with OME may mimic sensorineural hearing loss. This study evaluated NHS and ABR findings on and optimal timing for ABR reassessment after tympanostomy in patients with CLP. Methods: We conducted a retrospective study reviewing 271 CLP cases at our institution. The data included the cleft type, NHS results, ABR findings, OME incidence, and tympanostomy rate. Subgroup analyses compared ABR results before and after tympanostomy and via postoperative timing. Statistical comparisons were performed using the Mann–Whitney U test and Fisher’s exact test. Results: The NHS referral rate was 14.0%, and the OME incidence was 48.7%. These cases occurred in patients with cleft palate involvement, with an OME prevalence of 73.4%. Tympanostomy was performed in 72.6% of cases. Among 36 ears tested pre- and post-tympanostomy, wave V thresholds improved from 61.67 ± 16.08 to 34.72 ± 6.54 dBnHL (p < 0.0001), and wave I latency decreased from 2.27 ± 0.36 to 1.76 ± 0.12 ms (p < 0.0001). Postoperative wave V thresholds were significantly better in the ≥15-day group (p = 0.037), with 65% (17/26) of ears showing thresholds <40 dBnHL compared to 25% (3/12) in the <15-day group (p = 0.035). No timing-related differences were found regarding wave I latency. Conclusions: Tympanostomy significantly improved the ABR results in children with CLP and OME. Reassessment on or after postoperative day 15 may yield more accurate results and may help to reduce parental anxiety. Full article

Objective: The aim of this study is to develop and evaluate the antibacterial and anti-biofilm efficacy of ciprofloxacin-coated tympanostomy tubes (TTs) using a sustained-release varnish (SRV-CIPRO) and introduce a novel tympanic membrane model for preclinical evaluation. Study Design: This was an in vitro experimental study. Setting: This study was conducted in a biofilm research laboratory in an academic medical center. Methods: Sterile fluoroplastic TTs were coated with SRV-CIPRO or placebo varnish. A novel tympanic membrane (TM) model was developed using a layered agar–plastic system. Antibacterial activity, biofilm inhibition, and bacterial viability were assessed through agar diffusion, MTT, ATP quantification, HR-SEM, and SD-CLSM. Results: SRV-CIPRO-coated TTs exhibited sustained antibacterial activity for up to 10 days. Compared to the placebo, SRV-CIPRO significantly inhibited biofilm formation, reduced metabolic activity, and decreased bacterial viability (p < 0.05). Imaging confirmed fewer bacterial colonies on SRV-CIPRO TTs. The TM model allowed realistic testing of tube insertion and infection simulation. Conclusion: SRV-CIPRO-coated TTs offer sustained antibiotic delivery, potentially reducing postoperative otorrhea and biofilm-related complications. The TM model provides a platform for preclinical evaluation of middle ear devices. Full article

Purpose: Gradenigo syndrome is a rare complication of acute otitis media (AOM) in children, characterized by suppurative otitis media, unilateral facial pain, and ipsilateral abducens nerve palsy. This review summarizes pediatric data on the presentation, diagnostics, treatment, and outcomes. Methods: A literature research was conducted using the terms “Gradenigo syndrome,” “petrous apicitis,” and “complications otitis media.” Pediatric cases were analyzed for demographics, symptoms, diagnostic findings, therapeutic strategies, and clinical outcomes. Results: Sixty-three articles described 65 patients (mean age: 8.0 years). The classic triad occurred in 22% of cases; 74% showed incomplete presentations. Imaging revealed petrous apex inflammation (84%) and petrous bone tip obliteration (49%). Antibiotics were administered in 88% of cases, most commonly third-generation cephalosporins. Surgery was performed in 72%, mainly myringotomy, tympanostomy tube insertion, and mastoidectomy; no direct petrous apex approaches were reported. Pathogens were identified in 41% of cases, most commonly Fusobacterium necrophorum. Clinical improvement occurred in 98%, with 75% achieving a complete resolution; complications were reported in 29%, including one fatality (2%). Conclusions: Given its variable presentation, comprehensive diagnostic imaging is essential for the diagnosis of Gradenigo syndrome. Early broad-spectrum antibiotic therapy is essential. Surgical intervention is required in severe cases. Long-term targeted antibiotic therapy may help prevent recurrence. Full article

Background and Objectives: Otitis media with effusion (OME), frequently associated with obstructive adenoid hypertrophy (OAH), is a leading cause of paediatric hearing loss. Clinically distinguishing effusion types (serous vs. mucoid) and predicting postoperative hearing recovery are unresolved challenges. This study evaluated the utility of preoperative blood inflammatory markers in predicting effusion characteristics and short-term hearing outcomes following adenoidectomy with tympanostomy tube (TT) insertion. Materials and Methods: In this retrospective cohort study, 232 children under 12 years old in 2024 and undergoing adenoidectomy (with or without TT insertion) were categorised into serous OME (n = 42), mucoid OME (n = 78), and non-effusion (n = 112) groups. Preoperative blood sample analyses assessed neutrophil, lymphocyte, eosinophil, basophil, and platelet counts, along with derived indices, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), eosinophil-to-basophil ratio (EBR), mean platelet volume (MPV), and systemic immune–inflammation index (SII). Hearing was evaluated at 2 weeks and 1 month postoperatively. Statistical analyses used SPSS v.28, with significance set at p < 0.05. Result: Mucoid OME patients exhibited significantly elevated neutrophil counts, platelet counts, eosinophils, NLR, and SII compared to those in serous OME and non-effusion groups (p < 0.05). All serous OME children achieved normal hearing by the first follow-up, whereas 15.4% of mucoid OME cases had transient mild hearing loss persisting after 2 weeks (p = 0.008; OR=15.97) but resolving by 1 month. Preoperative neutrophil count independently predicted delayed hearing recovery (p = 0.021). Conclusions: Systemic inflammatory markers, particularly neutrophil count, NLR, and SII, effectively differentiate mucoid OME from other effusion types and correlate with short-term hearing recovery. Neutrophil count may serve as a prognostic tool for surgical planning and patient counselling. Prospective studies are warranted to validate these findings in broader paediatric populations.

The aim of this study was to analyze the spectrum of Candida manifestations in the orofacial region to address the lack of comprehensive data in the diverse pediatric population. This retrospective study included all positive Candida findings in patients aged 0–18 years treated between 2014 and 2023 at a university maxillofacial department in Germany and evaluated associated risk profiles, comorbidities and species distributions. Candida infection sites included oral mucosa, dental abscesses and otitis media. Candida was more frequent in children with pre-existing conditions, particularly immunosuppression, neuromuscular disorders and facial deformities. Tympanostomy tubes and recent antibiotic use were significant risk factors for Candida in otitis media. Whereas in dental abscesses, Candida had a significant proportion independent of prior antibiotic use. Non-albicans subspecies, particularly Candida parapsilosis, were notably more prevalent in the middle ear compared to oral and dental infections. Candida manifests in various forms in the orofacial region, with different characteristics and species distributions. Further investigations are needed to better understand the role of Candida as a symptom or a contributor to an underlying condition. Full article

Background/Objectives: Some ophthalmic antibiotics are publicly subsidised in New Zealand (NZ) for off-label use in the ear, however, this utilisation has not previously been described. This study compared the utilisation of ophthalmic chloramphenicol and ciprofloxacin in the eye and ear, among NZ children. Methods: This study involved clinical record review, and included 11,617 prescriptions of ophthalmic chloramphenicol and ciprofloxacin in 2022, for children aged five years or under in Auckland, NZ. Prescriptions of chloramphenicol and ciprofloxacin for eye and ear use were compared by: patient age, gender, ethnicity and socioeconomic deprivation, indication, community or hospital prescribing and number of repeat prescriptions. Statistical analysis was performed using Chi-squared test and multinomial regression. Results: Most ophthalmic ciprofloxacin was used in the ear (84%). In contrast, almost all chloramphenicol was used in the eye (96%). Post-operative use following tympanostomy tube insertion accounted for half of all hospital-prescribed ophthalmic ciprofloxacin used in the ear. Utilisation of chloramphenicol and ciprofloxacin in the eye and ear was similar, with more prescriptions for children aged one year and males, and most children received only one prescription. Māori and Pacific children generally received fewer prescriptions. Pacific children were more likely than Māori children to receive hospital-prescribed ophthalmic ciprofloxacin for use in the ear (adjusted OR 6.7, p = 0.025). Conclusions: These findings highlight the utilisation of ophthalmic ciprofloxacin in the ear in NZ children. These findings will inform decision-making in the public funding of medications, policy development in equitable medication access, and more collaborative efforts to improve antimicrobial use.

Background/Objectives: This register study elucidates the national trends in the otolaryngologic surgery volume in Finland over a ten-year period. In particular, we investigated whether the pandemic, which had a marked effect on communicable diseases, had an impact on infection-related ear, nose, and throat (ENT) procedures. For reference, we used noninfectious ENT procedures. Methods: The data of this study consisted of the volumes of different otolaryngological surgical procedures in Finland from 2012 to 2022. A linear regression model was applied to calculate long-term trends in surgery volumes. The annual predicted and observed surgical volumes of each procedure were compared. In addition, different procedures were compared based on whether they were mostly infection-related, non-infection-related, or both. Results: The results revealed that the pandemic altered the trends of many ENT procedures, and during the pandemic, infection-related surgeries declined more than non-infection-related surgeries did. The decline in infection-related surgery volumes seems to have lasted longer than the coronavirus disease 2019 (COVID-19) pandemic itself, as only tympanostomies and mastoidectomies of all the infection-related procedures included in this study have returned to the pre-pandemic trend. Some non-infection-related procedures and procedures with mixed indications also declined during the pandemic and sustained their reduction even in 2022. Conclusions: This study provides a nationwide insight into ENT surgery volumes in Finland over a ten-year period. Although causative reasoning cannot be conducted based on this study, it still provides a good indication of how the absence of respiratory viruses and multifactorial societal restriction measures could have a long-lasting effect on the epidemiology and management of many ENT diseases.

Digital high-speed videomicroscopy (DHSV) is a crucial tool for evaluating ciliary function in children suspected of primary ciliary dyskinesia (PCD). However, until now, samples are taken without anesthesia due to uncertainty about its effect on ciliary function and DHSV interpretation. This study aimed to investigate the impact of general anesthesia on ciliary functional analysis by DHSV in a series of three patients listed for ENT surgeries, which could improve diagnostic procedures for pediatric patients. Patient 1 (7-year-old girl) underwent adenotonsillectomy and tympanostomy placement tube, while patients 2 (17-month-old boy) and 3 (15-month-old girl) underwent adenoidectomy and tympanostomy placement tube. All patients underwent nasal brushing before general anesthesia (control sample). Experimental samples were taken in the contralateral nostril at the time of equilibration of the anesthetic agents (sevoflurane, propofol, sufentanil). Ciliary beat frequency and pattern were measured using digital high-speed videomicroscopy. Our findings highlighted the variability of respiratory ciliary function under general anesthesia among individuals. Our results emphasize the need for caution when interpreting ciliary function data obtained during general anesthesia. Further research with larger cohorts is warranted for validation. Full article

Eosinophilic otitis media (EOM) is a rare middle ear disease with unfavorable outcomes. Under the current diagnostic criteria of EOM, it is challenging to suspect EOM before tympanostomy. Therefore, this study attempted to use blood eosinophil levels for the differential diagnosis of EOM from other conditions. Three disease groups with features of recurrent otorrhea were categorized, which included the following: EOM (n = 9), granulomatosis with polyangiitis (GPA, n = 12), and primary ciliary dyskinesia (PCD, n = 6). Clinical and radiological characteristics were analyzed in the three groups. Patients who underwent ventilation tube insertion due to serous otitis media were enrolled as the control group (n = 225) to evaluate the diagnostic validity of blood eosinophilia. The EOM group showed a significantly higher blood eosinophil concentration (p < 0.001) and blood eosinophil count (p < 0.001) compared to the GPA and PCD groups. The estimated sensitivity and specificity for diagnosing EOM from OME patients who underwent ventilation tube insertion were 100% and 95.6%, respectively. In addition, EOM tended to have protympanic space soft tissue density and a relatively clear retrotympanic space in temporal bone computerized tomography. Blood eosinophil evaluation is a significant clinical indicator of EOM. Furthermore, the assessment of exclusive protympanic soft tissue density can provide an additional diagnostic clue.

This study examined the effects of different types of tympanostomy tubes in pediatric patients undergoing cleft palate (CP) surgery in order to provide guidance for the proper insertion of tympanostomy tubes in the management of otitis media with effusion (OME). A total of 101 ears with middle ear effusion in 51 patients with CP were included in this study. Patients underwent palatoplasty and tympanostomy tube surgery at the same time. The type of tube inserted (Paparella type 1 or 2), the severity of CP, and types of palatoplasty surgeries were investigated. All patients were followed up for at least 6 months, and recurrence rates, complications, and reinsertion surgery were evaluated. The rate of OME recurrence after spontaneous tube extrusion was significantly higher in the type 1 group than in the type 2 group (44.3% vs. 19.4%, respectively, p = 0.016). Persistent eardrum perforation was more common in the type 2 group than in the type 1 group (41.9% vs. 12.9%, respectively, p = 0.001). The tube reinsertion rate was higher in the type 1 group than in the type 2 group (22.9% vs. 3.2%, respectively, p = 0.015). The tube reinsertion rate decreased to 8.6% in cases of palatoplasty with Sommerlad’s technique, even with type 1 tube insertion, which was not significantly different from the reinsertion rate in the type 2 group (3.7%, p = 0.439). The Paparella type 1 tube would be a better choice in cases of palatoplasty performed using Sommerlad’s technique, particularly considering the higher rate of persistent eardrum perforation after extrusion associated with the Paparella type 2 tube. Alternatively, a larger size type 2 tube may be considered in other surgeries to decrease the frequency of recurrence and tube reinsertion. Full article

Background: The emergence of ChatGPT, a state-of-the-art language model developed by OpenAI, has introduced a novel avenue for patients to seek medically related information. This technology holds significant promise in terms of accessibility and convenience. However, the use of ChatGPT as a source of accurate information enhancing patient education and engagement requires careful consideration. The objective of this study was to assess the accuracy and reliability of ChatGPT in providing information on the indications and management of complications post-tympanostomy, the most common pediatric procedure in otolaryngology. Methods: We prompted ChatGPT-3.5 with questions and compared its generated responses with the recommendations provided by the latest American Academy of Otolaryngology–Head and Neck Surgery Foundation (AAO-HNSF) “Clinical Practice Guideline: Tympanostomy Tubes in Children (Update)”. Results: A total of 23 responses were generated by ChatGPT against the AAO-HNSF guidelines. Following a thorough review, it was determined that 22/23 (95.7%) responses exhibited a high level of reliability and accuracy, closely aligning with the gold standard. Conclusion: Our research study indicates that ChatGPT may be of assistance to parents in search of information regarding tympanostomy tube insertion and its clinical implications. Full article

Intraoperative auditory brainstem response (ioABR) testing following tympanostomy tube (TT) placement may be biased due to temporary threshold shifts (TTS). The purpose of the study was to assess the evidence for TTS in children who have undergone ioABR using prolonged latencies of wave I (males > 1.95 ms, females > 1.88 ms) as a marker of a persisting air–bone gap. Eighty-three children underwent ioABR following surgical procedures at University Hospital Bonn, Germany. The primary outcome measure was the latency of wave I at 80-dB SPL. The total sample consisted of 66 males (79.5%) and 17 females (20.5%) with a mean (SD) age of 46.4 (26.6) months. Of 163 operated ears (83 children), 72 (44.2%) had no middle ear fluid, 19 (11.6%) serous fluid, and 72 (44.2%) mucoid fluid. The risk of having a prolonged latency of wave I at 80-dB SPL was OR 4.61 (95% CI 2.01–10.59; p < 0.001) in those with mucoid fluid as compared to those without mucoid fluid. Intraoperative ABR results should account for sex differences and be interpreted with caution and be verified. Ultimately, parents should be engaged in a preoperative discussion to decide if an ioABR should be postponed if mucoid fluid was found. Full article

The formation of antibiotic-resistant strain biofilms in tympanostomy tubes results in persistent and refractory otorrhea. In the present study, we investigated the in vitro antibiofilm activity of thymol against biofilms formed by methicillin-resistant Staphylococcus aureus (MRSA) and ciprofloxacin-resistant Pseudomonas aeruginosa (CRPA), using live and dead bacterial staining and adhesion, biofilm formation, biofilm eradication, and biofilm hydrolytic activity assays. The antibiofilm activity of thymol against tympanostomy tube biofilms formed by MRSA and CRPA strains was examined using a scanning electron microscope. In response to thymol treatment, we detected significant concentration-dependent reductions in the viability and adhesion of MRSA and CRPA. Exposure to thymol also inhibited the formation of both MRSA and CRPA biofilms. Furthermore, thymol was observed to enhance the eradication of preformed mature biofilms produced by MRSA and CRPA and also promoted a reduction in the rates of MRSA and CRPA hydrolysis. Exposure to thymol eradicated extracellular polysaccharide present in the biofilm matrix produced by MRSA and CRPA. Additionally, thymol was observed to significantly eradicate MRSA and CRPA biofilms that had formed on the surface on tympanostomy tubes. Collectively, our findings indicate that thymol is an effective inhibitor of MRSA and CRPA biofilms, and accordingly has potential utility as a therapeutic agent for the treatment of biofilm-associated refractory post-tympanostomy tube otorrhea resulting from MRSA and CRPA infection.

Background: The purpose of this study is to analyse the long-term effects of a 12-week course of topical steroids on adenoid size and its mucus using endoscopy and on middle ear effusion measured by tympanometry. Methods: The study presents an endoscopic choanal assessment of the change in adenoid size (adenoid to choanae ratio, A/C ratio) and its mucus coverage in 165 children with Grade II and III adenoid hypertrophy three to six months after finishing a 12-week course of intranasal steroid treatment with mometasone furoate. Additionally, tympanometry was performed to measure middle ear effusion. Changes in the tympanograms were analysed. Results: The mean A/C ratio before treatment was 65.73%. Three to six months after finishing a 12-week course of intranasal steroid treatment, the mean A/C ratio decreased to 65.52%, although the change was not statistically significant (p = 0.743). There was no change in adenoid mucus according to the MASNA scale before and three to six months after the end of the steroid treatment (p = 0.894). Long-term observations of tympanograms before and three to six months after the end of the treatment did not show improvement (p = 0.428). Conclusions: The results indicate that there was no effect of topical steroids on adenoid size, its mucus and otitis media with effusion (OME) three to six months after finishing a 12-week course of treatment. In the light of performed study, decision of adenoidectomy and tympanostomy should not be procrastinated. Full article
