Special Issue Information

Dear Colleagues,

We would be honored to have robust contributions from eminent experts on head and neck reconstructive surgery in order to update the scientific literature on this fascinating topic. This Special Issue, “Innovation in Head and Neck Reconstructive Surgery—Series 2”, is a new volume; 16 papers were published in the first volume. For more details, please visit:

The field of head and neck reconstruction is exceptionally complex. Many of the anatomical structures requiring reconstruction have a crucial role in facial morphology and for functions such as speech, swallowing, and mastication. All these aspects strongly influence the patient’s daily quality of life. The lack of effective reconstruction techniques in the distant past left surgeons and patients with poor outcomes.

Over the past few years, the development of new technologies such as virtual surgical planning and 3D printing have been shown to result in better outcomes in terms of reconstructive accuracy, with good improvement in results as compared to traditional reconstruction techniques. The field of head and neck reconstruction is on the move. In fact, computer-assisted surgery with customized implants is becoming increasingly common for head and neck reconstruction, also associated with revascularized tissue transfer. These techniques allow surgeons to provide increasingly personalized reconstruction, improving the average results and reducing surgical time.

The present Special Issue aims to explore these new frontiers of reconstructive surgery as supported by 3D technology.

Purpose: Acquired defects of the central face pose significant challenges in achieving acceptable cosmetic and functional outcomes. The site, size, and depth of tissue loss often render local tissues inadequate for the repair of major nasal defects. In this article, we aim to demonstrate the efficacy of radial forearm-free flaps as an ideal choice for various central facial unit reconstructions. Methods: This study encompassed patients treated between 2020 and 2022 who underwent facial reconstruction using radial forearm flaps. These flaps were employed in eleven patients with defects involving the lower lid, nose, upper lip, and lower lip. Additionally, we used osteocutaneous flaps in one patient to reconstruct a right nasal bone defect. In three patients requiring medial and lateral canthal tendon reconstruction in one case and oral sphincter reconstruction in two cases, the palmaris longus tendon was included with the flap. Results: In the majority of cases, we achieved good to excellent aesthetic and functional results. Notably, there were no instances of flap failure or partial necrosis in this series. All patients experienced uneventful healing at the donor site. Conclusions: The radial forearm-free flap stands as an ideal and reliable method for reconstructing various facial defects. It offers efficient and thin-conforming skin coverage. Full article

Free flap reconstruction is the standard of care for extensive defects of the head and neck area. In this study, two types of free flaps, the antero-lateral thigh flap (ALT) and the vastus lateralis muscle flap, were compared. The primary endpoint was flap success, secondary endpoints were complication rates, hospitalization and surgery time. Cases with defect situations of the scalp and consecutive microvascular free flap reconstructions using either ALT flaps or vastus lateralis muscle flaps between 2014 and 2022 were retrospectively analyzed. Indications, perioperative handling and outcomes were compared. Twenty patients were included in the analysis. Ten patients (50%) received a free flap reconstruction using an ALT flap and ten patients (50%) received a vastus lateralis flap. A simultaneous two-team approach was possible in each case and the flap success rate was 100% with the need for one successful anastomosis revision. The mean defect size in our cohort was 147 ± 46 cm2. There were no significant differences in surgery time, duration of hospitalization or complication rate between both cohorts. Both free flaps, the ALT and the vastus lateralis flap, are suitable for the closure of large scalp defects. They provide high success rates, short surgery times without the need for patient repositioning and low donor-site morbidity. The vastus lateralis muscle flap bares the advantage of being perforator-independent and allows for the preparation of long vessels for anastomosis if needed while baring the disadvantage of a prolonged period of healing via granulation or the need for secondary surgery in terms of covering by split-thickness skin grafts which may interfere with necessary adjuvant treatment in oncological patients.

Polyetheretherketone (PEEK) has become the biomaterial of choice for repairing craniofacial defects over time. Prospects for the point-of-care (POC) fabrication of PEEK customized implants have surfaced thanks to the developments in three-dimensional (3D) printing systems. Consequently, it has become essential to investigate the characteristics of these in-house fabricated implants so that they meet the necessary standards and eventually provide the intended clinical benefits. This study aimed to investigate the effects of the steam sterilization method on the dimensional accuracy of POC 3D-printed PEEK customized cranial implants. The objective was to assess the influence of standard sterilization procedures on material extrusion-based 3D-printed PEEK customized implants with non-destructive material testing. Fifteen PEEK customized cranial implants were fabricated using an in-house material extrusion-based 3D printer. After fabrication, the cranial implants were digitalized with a professional-grade optical scanner before and after sterilization. The dimensional changes for the 3D-printed PEEK cranial implants were analyzed using medically certified 3D image-based engineering software. The material extrusion 3D-printed PEEK customized cranial implants displayed no statistically significant dimensional difference with steam sterilization (p > 0.05). Evaluation of the cranial implants’ accuracy revealed that the dimensions were within the clinically acceptable accuracy level with deviations under 1.00 mm. Steam sterilization does not significantly alter the dimensional accuracy of the in-house 3D-printed PEEK customized cranial implants. Full article

Although the fibula free flap represents the gold standard for mandibular reconstructions, when implanted as a single barrel, this flap does not have the cross-sectional requisites to restore the native mandibular height, which is in turn required for the implant-supported dental rehabilitation of the patient. Our team has developed a design workflow that already considers the predicted dental rehabilitation, positioning the fibular free flap in the correct craniocaudal position to restore the native alveolar crest. The remaining height gap along the inferior mandibular margin is then filled by a patient-specific implant. The aim of this study is to evaluate the accuracy in transferring the planned mandibular anatomy resulting from said workflow on 10 patients by means of a new rigid body analysis method, derived from the evaluation of orthognathic surgery procedures. The analysis method has proved to be reliable and reproducible, and the results obtained show that the procedure already has satisfactory accuracy (4.6° mean total angular discrepancy, 2.7 mm total translational discrepancy, 1.04 mm mean neo-alveolar crest surface deviation), while also pointing out possible improvements to the virtual planning workflow.
