Retrospective cohort study rethinking lip reconstruction: Versatility of the depressor anguli oris myocutaneous flap for large full-thickness defects.

Background: Large full-thickness lip defects present a reconstructive challenge.

Objective: To describe the impact on clinical outcomes and institutional cost of the depressor anguli oris myocutaneous (DAOM) flap as an axial pattern transposition flap for reconstruction of large, full-thickness lip defects.

Methods: A multicenter retrospective cohort study of adults with large full-thickness lip defects who underwent DAOM flap reconstruction from 2011 to 2018 was conducted.

Higher Computed Tomography (CT) Scan Resolution Improves Accuracy of Patient-specific Mandibular Models When Compared to Cadaveric Gold Standard.

Background: 3D-printed patient-specific anatomical models are becoming an increasingly popular tool for planning reconstructive surgeries to treat oral cancer. Currently there is a lack of information regarding model accuracy, and how the resolution of the computed tomography (CT) scan affects the accuracy of the final model.

Purpose: The primary objective of this study was to determine the CT z-axis resolution necessary in creating a patient specific mandibular model with clinically acceptable accuracy for global bony reconstruction.

Aerosol and droplet generation from orbital repair: Surgical risk in the pandemic era.

Introduction: The highly contagious COVID-19 has resulted in millions of deaths worldwide. Physicians performing orbital procedures may be at increased risk of occupational exposure to the virus due to exposure to secretions. The goal of this study is to measure the droplet and aerosol production during repair of the inferior orbital rim and trial a smoke-evacuating electrocautery handpiece as a mitigation device.

Aerosol and droplet generation from mandible and midface fixation: Surgical risk in the pandemic era.

Purpose: The COVID-19 pandemic has led to concerns over transmission risk from healthcare procedures, especially when operating in the head and neck such as during surgical repair of facial fractures. This study aims to quantify aerosol and droplet generation from mandibular and midface open fixation and measure mitigation of airborne particles by a smoke evacuating electrocautery hand piece.

Materials And Methods: The soft tissue of the bilateral mandible and midface of two fresh frozen cadaveric specimens was infiltrated using a 0.

Petrous Apex Pneumatization: Influence on Postoperative Cerebellopontine Angle Tumor Cerebrospinal Fluid Fistula.

Objective: Multiple investigators have sought to identify risk factors for cerebrospinal fluid (CSF) leak following cerebellopontine angle (CPA) tumor resection. We evaluated whether pneumatization of the petrous apex (PA) is a risk factor for CSF fistula.

Method: We conducted a retrospective chart review at 2 major tertiary academic institutions undergoing CPA tumor resection and analyzed their respective head or temporal computed tomography (CT) scans if available.
