Purpose: Prophylactic tracheotomy has traditionally been performed during composite mandibular resection of oral cavity cancer to avoid postoperative airway compromise. The purpose of the present study was to measure the frequency and identify the factors associated with an increased or a decreased risk of an adverse airway event (AAE) within 30 days postoperatively.
Patients And Methods: A retrospective cohort study of patients who had undergone composite mandibular resection for oral cancer from 2006 to 2018 was conducted at the University of Tennessee Medical Center. The primary predictor variable was composite resection with or without immediate flap reconstruction. The primary outcome variable was realization of a 30-day AAE, defined as the requirement for tracheotomy for any reason, emergent endotracheal reintubation at any time during the postoperative admission, or prolonged (>48 hours) postoperative endotracheal intubation. The secondary outcome variable was the inpatient length of stay. Descriptive and bivariate statistics were used to compare the patients with and without an AAE for demographic, confounding, and clinical characteristics.
Results: A total of 114 patients were identified through retrospective medical record review. The prevalence of AAEs in the sample was 8.8% (10 of 114). None of the 49 patients without immediate flap reconstruction developed an AAE. Of the 65 patients who had undergone flap reconstruction, 10 (15.4%) developed an AAE. The χ analysis revealed a significantly greater rate of AAEs when flap reconstruction was implemented (P < .05). Also, a significantly greater rate of AAEs was found in the group requiring resection of the floor of the mouth with bilateral neck dissections and immediate flap reconstruction compared with all other flap reconstruction groups (P < .05).
Conclusions: A composite resection involving the floor of the mouth with bilateral neck dissection and flap reconstruction should receive strong consideration for prophylactic tracheotomy to avoid an AAE.

Background: Although the literature supports a shorter course of 24 h of prophylaxis after head and neck free flap reconstruction, studies supporting this duration do not differentiate between flap types. There is a paucity of evidence on the optimal duration of prophylaxis for osteocutaneous free flaps with hardware, which may have higher rates of post-operative complications compared to other free flaps. This study aimed to examine the effect of different lengths of antibiotic prophylaxis on surgical site infection (SSI) rates after head and neck reconstruction with osteocutaneous free flaps and hardware.

Background: Sinonasal malignancies, in which squamous cell carcinomas are the most common are rare and difficult to treat given the location and anatomical structures involved. Sinonasal malignancies often present late due to non-specific and benign symptoms. Partial resections are often associated with poorer outcomes [1].

This novel hybrid single-double-single barrel (1-2-1) design for fibula free flap reconstruction addresses the unique challenges presented by Brown Class III mandibular defects, which involve long-span defects at both bodies of the mandible and the chin. The importance of this design lies in its ability to overcome the limitations of traditional approaches in terms of mandible height and pedicle length, while optimizing both functional and esthetic outcomes.The technique utilizes a combination of single-double-single barrel fibula segments to achieve ideal esthetics and support for dental prosthesis across different areas of the mandible.

Reconstruction after the excision of a lower eyelid tumor should be focused on the restoration of both functionality and aesthetic appeal. Accurate identification and appropriate intervention are crucial for the favorable resolution of the condition. This technique used a nasolabial mucosal-myocutaneous propeller flap to reconstruct a huge full-thickness defection of right lower eyelid because of basal cell carcinoma.
