Nonvascularized bone grafts (NBGs) represent a practical method of mandibular reconstruction that is precluded in head and neck cancer patients by the destructive effects of radiotherapy. Advances in tissue-engineering may restore NBGs as a viable surgical technique, but expeditious translation demands a small-animal model that approximates clinical practice. This study establishes a murine model of irradiated mandibular reconstruction using a segmental iliac crest NBG for the investigation of imperative bone healing strategies...

Oropharyngeal tumor is traditionally resected from an open approach, often necessitating the need of a midline mandibulotomy in order to remove tumor safely with oncologic margins. The limitations imposed by a transoral route include poor visualization of the inferior extent of the oropharynx, rigid instrumentation, and inability to resect tumor that extends caudally into the supraglottis. While visualization with angled endoscopes, coupled with flexible laser development and microscopic magnification may overcome some of these limitations, this technique suffers from linear trajectory of the instruments which hampers expedient surgical resection in a 3-dimensional fashion...

INTRODUCTION: Minimally invasive transoral surgery for oropharyngeal cancer is a challenge for head and neck surgeons because of the inside-out anatomic presentation and the confined workspace. This study was performed to describe the main neurovascular and muscular landmarks in a transoral approach. The authors propose an anatomic stratification for this surgery. MATERIALS AND METHODS: Lateral wall of the oropharynx and base of the tongue of 15 formalin-fixed heads (30 sides) and 5 fresh cadaveric heads (10 sides) sagittal sectioned were dissected from the inside outwards...

Background: Selection of recipient vessels is one of the key factors for a successful microvascular reconstruction. Non-availability of primary recipient vessels in the vicinity necessitates surgeon to approach a remote second-line vascular access. Transverse cervical vessels (TCV) have been described as second-line vascular access for head-and-neck reconstructions. Due to its location, their use can be extended to the proximal chest and upper arm reconstructions. Aim: The aim of the study is to analyse the reliability of TCV as second-line recipient vessels for the upper arm and chest reconstructions in addition to the head-and-neck reconstructions...

BACKGROUND: Right-sizing instrument trays reduce processing and replacement costs, physical strain, and turnover times. Historically, a 98-instrument head and neck tray has been used for breast lumpectomy cases at our institution. Observations revealed that many instruments on the tray were not used during the breast cases. With the significant number of surgical breast lumpectomies performed annually, tray downsizing could significantly reduce costs and physical strain. METHODS: Surgical technicians identified instruments needed for a standard breast lumpectomy...

BACKGROUND: MRI is predictive of adverse local tissue reactions (ALTRs) after THA but how MRI directly relates to implant surface wear, fretting, and trunnion corrosion at different articulations between implant components remains unclear. MRI generates high-contrast images to display soft tissues around arthroplasty and may provide a surgeon the means to distinguish and differentiate host-related synovial patterns as a response to either polyethylene wear or metal wear and corrosion products...

BACKGROUND: Free tissue reconstruction is reliable in suitable patients but patient selection remains a challenge for the reconstructive surgeon. The anterolateral thigh (ALT) free flap and pedicled pectoralis major myocutaneous flap (PMMF) are two common reconstructive options for a lateral temporal bone resection defect. The threshold at which free tissue reconstruction should be considered over locoregional reconstruction is not defined. We sought to define reconstructive flap choice in the setting of medical comorbidities that may dissuade free tissue transfer...

Eric R Carlson, Thomas Schlieve
Salivary gland tumors are rare pathologic entities that are derived from major and minor salivary gland tissue located throughout the head and neck region. These tumors are distinctly heterogenous, comprising numerous cell types, especially those deemed malignant. The incidence of malignant salivary gland tumors is widely distributed in both adult and pediatric patient populations. Accurate diagnosis and optimal treatment of these tumors pose challenges to both interpreting pathologists and ablative surgeons...

Cancers of the oral cavity and paranasal sinuses often require ablative surgery with adjuvant therapy in most cases. Large, postablative defects of the mandible and the maxilla present several challenges to the reconstructive surgeon. Functional and cosmetically satisfactory restoration requires a thorough understanding of the underlying disease process, a firm grasp of the nuances of head and neck anatomy, and an ability to plan and execute a reconstruction with the most suitable tissue for each particular patient...
