For a variety of head and neck cancers, specifically those of the oropharynx, larynx, and hypopharynx, minimally invasive trans-oral approaches have been developed to reduce perioperative and long-term morbidity. However, in trans-oral surgical approaches anatomical deformation due to instrumentation, specifically placement of laryngoscopes and retractors, present a significant challenge for surgeons relying on preoperative imaging to resect tumors to negative margins. Quantifying the deformation due to instrumentation is needed in order to develop predictive models of operative deformation...

OBJECTIVE: To define and quantify common points and relationships within the anterior nasal septum and recognize the anatomic curvature of the dorsal and caudal septum as arcs with certain rises. STUDY DESIGN: Case series study. METHODS: Forty cadaveric quadrangular cartilages were dissected. Points along the septum were defined and relationships measured. Angles that composed the anterior septum using values that did account for the curvature of the anterior nasal septum, or classical L-strut values, were compared to C-strut values, which included rises away from the L-strut...

OBJECTIVES/HYPOTHESIS: Human papillomavirus (HPV)-positive and HPV-negative oropharyngeal squamous cell carcinoma (OPSCC) are distinct disease entities. Prognostic factors specific to each entity have not been adequately explored. Goals for this study were: 1) to determine whether HPV-positive and HPV-negative OPSCCs have distinct prognostic factors, and 2) to explore the prognostic significance of sex and race in OPSCC after HPV stratification STUDY DESIGN: Retrospective case series...

We herein report anesthetic management during aortic valve replacement for aortic valve regurgitation in a patient with adult mucopolysaccharidosis type II (MPS type 2) (Hunter syndrome). This disorder is rare and related to the accumulation of a mucopolysaccharide in lysosomes. It affects various organs, including the airways, heart, and central nerves. In children with MPS type 2, the risk of airway obstruction during anesthesia/sedation is high, and the degree of difficulty increases with aging. The patient described herein was a 33-year-old male without mental retardation...

INTRODUCTION: Recurrent respiratory papillomatosis results in hoarseness, stridor and airway obstruction. Management is surgical, with most surgeons using microdebrider or laser. Transoral robotic surgery (TORS) has been successfully utilised for the excision of oropharyngeal malignancies and paediatric airway surgery. This is the first case report of TORS being used for the excision of laryngeal papillomas. CASE REPORT: A 36 year old Chinese female was diagnosed with juvenile onset recurrent respiratory papillomatosis...

OBJECTIVE: Guidelines for vaccination of cochlear implant (CI) recipients have been promulgated and updated by the Center for Disease Control and Prevention (CDC) to mitigate bacterial meningitis risk. The objective of this study was to survey current CI specialists on: 1) knowledge of current CDC CI recipient immunization recommendations, and 2) impediments to implementation of those guidelines. METHODS: A survey to assess knowledge of the CI recipient vaccination guidelines was administered to the American Academy of Otolaryngology-Head and Neck surgery (AAO-HNS), the American Cochlear Implant Alliance (ACIA), and the American Neurotology Society (ANS)...

OBJECTIVES/HYPOTHESIS: Fellowship is the capstone of academic training and serves as preparation for an academic career. Fellows are expected to educate medical students and residents during and long after fellowship. However, little time is typically spent teaching fellows to become effective educators. We investigate a formal curriculum addressing teaching skills among fellows in otolaryngology-head and neck surgery (OHNS). STUDY DESIGN: E-mail survey. METHODS: We developed and implemented an educational program called Teach the Teacher to build skills as educators for fellows in OHNS...

OBJECTIVES/HYPOTHESIS: To develop a prediction model that can accurately predict the chance of success following revision stapes surgery in patients with recurrent or persistent otosclerosis at 2- to 6-months follow-up and to validate this model internally. STUDY DESIGN: A retrospective cohort study of prospectively gathered data in a tertiary referral center. METHODS: The associations of 11 prognostic factors with treatment success were tested in 705 cases using multivariable logistic regression analysis with backward selection...

BACKGROUND: Double lumen endobronchial tube (DLT) intubation is commonly used for one-lung ventilation in thoracic surgery. However, because of its large size and shape, it is difficult to perform intubation compared with a single lumen tube. The aim of this randomized controlled trial was to determine whether the McGrath videolaryngoscope has any advantage over the direct Macintosh laryngoscope for DLT intubation in patients with a simulated difficult airway. METHODS: Forty-four patients (19-60 years of age); scheduled to undergo general anesthesia with one-lung ventilation were assigned to 1 of 2 groups: DLT intubation with the McGrath videolaryngoscope (ML group [n = 22]); or conventional Macintosh laryngoscope (DL group [n = 22])...

OBJECTIVES: To describe facial sinus anatomy from an endoscopic perspective and present a radiologic classification. METHODS: Facial sinus was studied by endoscopy and high-resolution computed tomography (HRCT) scan in 39 temporal bones that underwent exclusive transcanal endoscopic approach. A radiomorphologic classification based on the relationship between the facial sinus and the mastoid portion of the facial nerve is created as follows. In type A facial sinus, the pneumatization of the facial sinus did not extend medially or posteriorly to the mastoid portion of the facial nerve...

OBJECTIVES: Idiopathic subglottic stenosis (ISGS) can have significant impacts on quality of life (QOL), but it remains unclear how patients' subjective responses correlate with objective measurement of disease severity. Peak expiratory flow percentage (PEF%) has been shown to be an effective measure of disease severity in subglottic stenosis. This study aims to identify the key QOL questions correlated with PEF% and proposes a statistical model for prediction of disease severity. METHODS: Patients with ISGS presenting to an academic laryngologist were included retrospectively from 2012 to 2016...

OBJECTIVES/HYPOTHESIS: To characterize health burden and determine the associated level of equality of laryngeal carcinoma (LC) burden at a global level. METHODS: One hundred eighty-four countries were organized by socioeconomic status using Human Development Index (HDI) categorizations provided by the United Nations Development Program. Disability-adjusted life years (DALYs), obtained from The Global Health Data Exchange, were calculated and compared between each HDI category for the period from 1990 to 2015...

Video laryngoscopy-assisted tracheal intubation devices have become alternatives to traditional laryngoscopes in recent years. This review will provide information on commonly used video laryngoscopes, and their clinical applications in airway management. Areas covered: In this review, the differences between video laryngoscopy and direct laryngoscopy, and the utilization of video laryngoscopes in specific clinical settings are discussed. Expert Commentary: Video laryngoscopy should be embraced as an initial approach to intubation in patients with suspected difficult airway...

BACKGROUND: Delays in postoperative head and neck (HN) radiotherapy have been associated with decreased overall survival; however, the impact of delays in postoperative HN chemoradiotherapy remains undefined. METHODS: All patients with nonmetastatic HN cancer (oral cavity, oropharynx, larynx, hypopharynx) who underwent curative intent surgery and received adjuvant chemoradiotherapy were identified from the National Cancer Database (2005-2012). Overall treatment time (OTT) was defined as the time from surgery to the end of radiation therapy...

OBJECTIVES/HYPOTHESIS: The outcomes of unilateral radiotherapy treatment for patients with p16/HPV-positive squamous cell carcinomas of unknown primary (SCCUP) affecting cervical lymph nodes are under-reported. Compared to radiating large volumes of the pharyngeal axis (the more common approach), this is potentially a much less toxic treatment for a good prognosis group. STUDY DESIGN: Retrospective cohort study. METHODS: We identified patients with SCCUP who were treated radically at our center and did not have parotid or isolated level IV or V nodal involvement...
