Scalp and cranial defects can occur as a result of cutaneous or bony malignancies, trauma, or surgical intervention for intracranial tumors. Soft tissue cranial reconstruction of composite defects presents a unique challenge given the relative tissue inelasticity of the scalp, need for tension free closure, and convex shape of the cranium. An added complexity is found in patients with large defects, cerebrospinal fluid leak, prior failed reconstruction, infection, or previous radiation. Methods and materials for skull reconstruction have evolved significantly over the years, allowing surgeons to repair even the most challenging composite defects with excellent success rates. This review aims to discuss and evaluate the available soft tissue options for cranioplasty coverage, with particular focus on hostile reconstructive fields and the use of free tissue transfer.

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.

Sinonasal squamous cell carcinoma (SNSCC) is a rare and aggressive malignancy which often presents at an advanced stage. The gold-standard treatment includes negative-margin surgical resection plus adjuvant therapy. In cases of orbital invasion, surgery requires orbital exenteration which can carry significant morbidity and result in decreased quality of life. In selected patients, induction chemotherapy (IC) can allow for orbit preservation without compromising oncologic outcomes. The available literature will be briefly discussed.

BACKGROUND: Endoscopic endonasal eustachian tube obliteration (EEETO) is a valuable option for treating cerebrospinal fluid rhinorrhea (CSFR) after lateral skull base surgery. Several small case series describe different techniques because of the rarity of this indication. OBJECTIVE: To review available literature on EEETO focusing on technique and factors affecting success. We also contribute a new case series using a knotless barbed suture technique. METHODS: This was a retrospective chart review of EEETO using barbed suture for CSFR at our institution from 2018 to 2021. Scoping review was performed by searching PubMed for articles on EEETO for CSFR. Patients were pooled for data syntheses. RESULTS: Our retrospective series contained 7 patients. Two patients (28.6%) required revision, but all were ultimately successful. Six studies were identified in scoping review for a combined total of 23 patients. Most of the patients initially underwent translabyrinthine (52.2%) resection of vestibular schwannoma (82.6%). Average time to initial CSFR was 362.6 days (standard deviation ± 1034.2, range 0-4320 days). Twenty-two patients underwent lumbar drain, and 11 underwent prior surgical attempts before EEETO. The initial success rate of EEETO was 65.2%. In 8 patients needing revision, EEETO was ultimately successful in 6. There were no differences in demographics or presentation between successful and revision cases. Seven different techniques were described. CONCLUSION: EEETO can treat CSFR after lateral skull base surgery. Revision surgery is common and difficult to predict. Several techniques have been described, and utilization of barbed suture is a viable method with comparable success, but without the need for endoscopic knot tying.
