Abstract
PURPOSE OF REVIEW This review analyzes the different ways of applying the subscapular system of flaps (SSSF) as a convenient and versatile solution for a large variety of head and neck oncologic defects. RECENT FINDINGS The ventral approach permits safe and efficient harvest of various chimeric SSSF in a supine position, thus allowing simultaneous flap preparation and tumor ablation. Conformational studies have revealed how similar the tip of the scapula is to the hard palate in terms of dimensions, shape, and conformation. This has led to favor horizontal placement of the scapular tip for palate reconstruction in most instances, addressing the vertical extension of the postmaxillectomy defect using denuded bony grafts surrounded by well vascularized chimeric muscular components. SUMMARY The SSSF possesses an unparalleled versatility to efficiently address small-medium sized soft tissue defects up to vast and complex composite resections. The chimeric components of these flaps benefit from a considerable independency provided by the length of the named arteries arising from the thoracodorsal pedicle, offering a high degree of freedom to accomplish the required in-setting. This reconstructive option should be implemented in every head and neck surgical team and offered to suitable patients.

Abstract
The mandible is a critical structure of the lower facial skeleton which plays an important role in several vital functions. Segmental resection of the mandible is at times required in patients with advanced oral cavity malignancies, primary mandibular tumors, and radiation or medication induced osteonecrosis. Mandibulectomy can significantly decrease quality of life, and thus mandibular reconstruction is an important aspect of the operative plan. Mandibular reconstruction is challenging due to the complex three-dimensional anatomy of the mandible, and the precision required to restore dental occlusion in dentate patients. Significant advances have been made over the past decade in the ability to reconstruct and rehabilitate patients after a segmental mandibulectomy. This review will highlight these advances and discuss the timing of dental implantation.

Objective evaluation of orbito-zygomatic reconstruction with scapular tip free flaps to restore facial projection and orbital volume. Oral Oncol 2021; 117:105268. [PMID: 33848724 DOI: 10.1016/j.oraloncology.2021.105268] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 03/13/2021] [Accepted: 03/21/2021] [Indexed: 11/15/2022]
Abstract
BACKGROUND Restoring anatomical contour and position of the malar eminence and orbital rim following ablative mid-face procedures is critical in maintaining facial contour and orbit position. OBJECTIVE To report our reconstructive approach using the scapular tip free-flap (STFF) for orbito-zygomatic defects, evaluating contour and overall shape restoration. METHODS The study included 2 series: a clinical cohort of 15 consecutive patients who underwent an orbito-zygomatic reconstruction with a STFF and a cohort of 10 patients who had CT scan imaging but did not have orbito-zygomatic surgical resection or reconstruction. Using a 3D software, overall conformance (OC) and contour conformance (CC) with respect to the mirrored contralateral (clinical cohort) or native zygoma (preclinical cohort) were analyzed. Postoperative orbital volumes were also measured in the clinical cohort. Mean, median, root-mean-square (RMS), minimum and maximum measurements were obtained both for OC and CC. Conformance values of clinical and preclinical cohort were compared to objectively evaluate the quality of reconstruction in terms of orbito-zygomatic framework restoration (Mann-Whitney test). RESULTS All measurements for OC and CC between scapular tip and the zygoma showed no differences, both on the clinical (RMS: OC 3.29 mm vs CC 3.32 mm -p = NS-) and preclinical (RMS: OC 2.03 mm and CC 2.31 mm -p = NS-) cohorts. Moreover, there were no differences in post-operative orbital volumes in the clinical cohort. Clinical outcomes of the case-series are also reported. CONCLUSION The STFF is highly effective in restoring facial projection and orbital volume in orbito-zygomatic reconstruction.

J Oral Maxillofac Surg 2020; 79:1345-1354. [PMID: 33508237 DOI: 10.1016/j.joms.2020.12.031] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Revised: 11/30/2020] [Accepted: 12/15/2020] [Indexed: 11/16/2022]
Abstract
PURPOSE The purpose of this study was to determine which of the most commonly used flaps restore contour more accurately in mandibular body reconstructions using conformance analyses and virtual measurements. METHODS Using normal computed tomography (CT) scans and a 3D software, mandibular body defects were virtually created. "Single shot" and osteotomized fibula flaps (SS-FF and O-FF), iliac crest flaps (ICF) and scapular tip flaps (STF) were digitally harvested and coregistered to reconstruct those defects. Conformance analyses were performed by calculating the root mean square (RMS) for overall and contour conformance. RESULTS Ten patients normal CT scans were included. The STF demonstrated improved overall conformance compared with the ICF, the SS-FF and the O-FF (RMS = 2.03 mm vs 4.53 mm vs 2.76 vs 2.37 mm, respectively; p<.001). Similar trends were seen for contour conformance in STF compared with the ICF and the SS-FF (RMS = 2.48 mm vs 4.50 mm vs 3.28 mm, respectively), whereas the O-FF performed better than STF (RMS = 1.85 mm vs 2.48 mm; p<.001). CONCLUSIONS The osseous component of the STF resembles the mandibular body more accurately than the one in the ICF and FF without the need for an osteotomy. Future clinical studies can help to elucidate the clinical impact of these virtual findings.

Abstract
The mandibular structures are a complex anatomical structure that is fundamental to many physiological and homeostatic functions. It may be involved in many pathological processes that require partial or complete removal. When this happens, reconstruction is mandatory to improve cosmetic outcome with its effect on social interaction as well as to provide an opportunity for complete dental rehabilitation with restoration of all physiological functions. This article will review the different reconstructive options available for complex defects of the mandibular complex. It will highlight the surgical options available to maximize functional restoration. Finally, it will discuss computer modeling to optimize reconstructive planning.

Abstract
OBJECTIVES/HYPOTHESIS To review the management of failed free tissue transfers among four large institutions over a 13-year period to provide data and analysis for a logical, algorithmic, experience-based approach to the management of failed free flaps. STUDY DESIGN Retrospective case series. METHODS A multi-institutional retrospective chart review of free tissue transfers to the head and neck region between 2006 and 2019 was performed. Patients with a failed free flap during their hospitalization after surgery to the head and neck were identified and reviewed. Patient age, co-morbidities, risk factors, flap characteristics, tumor specifics, and length of hospital stay were reviewed, collected, and analyzed. RESULTS One hundred eighteen flap failures met criteria. The most common failed flap in this review was the osteocutaneous flap 52/118 (44%). The recipient site of the initial free flap (P < .001) was the only statistically significant parameter strongly correlated with management. Osteocutaneous flap failures, fasciocutaneous, bowel, and muscle-only flaps tended to be managed most commonly with a second free flap. Myocutaneous flap failures were managed equally with either a second free flap or a regional flap. CONCLUSIONS The most important factor in management of a failed free flap is the recipient site. A second free flap is often the preferred treatment, but in the acute setting, local or regional flaps may be viable options depending on the recipient site, circumstances of flap loss, and patient- specific comorbidities. An algorithm for management of the acute flap loss is presented in this review. LEVEL OF EVIDENCE 4 Laryngoscope, 131:518-524, 2021.
