The submental island flap (SIF) is as an alternative to free flaps in head and neck reconstruction. 10 patients underwent submental flaps. All ten patients suffered failure of SIF as the definitive reconstructive procedure. Despite comparing favorably to free tissue transfer in published reports, our SIF had high failure rate.

Surgery can treat sleep apnea. An elderly male underwent lingual/palatine tonsillectomy for OSA. He was then found to have T3N2 p16+ squamous cell carcinoma. He is receiving chemoradiation. Recognition of occult malignancy in tonsillectomy specimens may facilitate early diagnosis and treatment for patients following sleep apnea surgery.

Background Surgical management of mega-goiters in endemic areas with extreme iodine deficiency presents unique challenges. Based on our initial 5-year experience (2007 to 2011) operating on mega-goiters in Gitwe, Rwanda, Africa, we modified our technique to a lateral approach which affords better exposure of the superior pole vessels and other vital neurovascular structures, thereby improving safety. We describe this lateral approach technique and review outcomes compared to the standard technique Methods From 2007 to 2019, we have conducted 13 annual surgical missions to low resource setting in Gitwe, Rwanda. Retrospective chart review of surgeries between 2012 and 2019 was performed to study outcomes using standard approach and lateral technique during the same time period. Results Over a period of 8 years (2012 to 2019), out of 192 total cases, lateral approach was used in 35 patients. No patient experienced significant intra-operative blood loss requiring transfusion. One patient had a post-operative hematoma requiring surgical intervention. Vocal cord mobility testing by transcutaneous laryngeal ultrasound was implemented in 2016. Of all patients, incidence of vocal cord weakness was 8.0% (11/137 patients tested) with less than 1/3 of these symptomatic. There was no statistically significant difference in vocal cord weakness noted in the two approaches (3/23 in lateral approach and 8/114 in standard approach) by Fisher’s exact test (P=0.34). Conclusions Lateral approach, by affording optimal exposure of the great vessels and the laryngeal nerves, reduces the risk of bleeding and nerve injury. Furthermore, inferiorly based strap muscle flap provides excellent coverage and cosmetic outcome.

Importance Graduate medical education has undergone a transformation from traditional long work hours to a restricted plan to allow adequate rest for residents. The initial goal of this restriction is to improve patient outcomes. Objective To determine whether duty hour restrictions had any impact on surgery-specific outcomes by analyzing complications following thyroid and parathyroid procedures performed before and after duty hour reform. Design, Setting, and Participants Retrospective cross-sectional analysis of the National Inpatient Sample (NIS).The NIS was queried for procedure codes associated with thyroid and parathyroid procedures for the years 2000 to 2002 and 2006 to 2008. Hospitals were divided based on teaching status into 3 groups: nonteaching hospitals (NTHs), teaching hospitals without otolaryngology programs (THs), and teaching hospitals with otolaryngology programs (THs-OTO). Main Outcomes and Measures Procedure-specific complication rates, length of stay, and mortality rates were collected. SAS statistical software (version 9.4) was used for analysis with adjustment using Charlson comorbidity index. Results Total numbers of head and neck endocrine procedures were 34 685 and 39 770 (a 14.7% increase), for 2000 to 2002 and 2006 to 2008, respectively. THs-OTO contributed a greater share of procedures in 2006 to 2008 (from 18% to 25%). With the earlier period serving as the reference, length of stay remained constant (2.1 days); however, total hospital charges increased (from $12 978 to $23 708; P < .001). Rates of postoperative hematoma (odds ratio [OR], 1.21; 95% CI, 1.06-1.38), hypoparathyroidism (OR, 1.27; 95% CI, 1.06-1.52), and unintentional vessel lacerations (OR, 1.36; 95% CI, 1.02-1.83) increased overall with NTHs (OR, 1.26; 95% CI, 1.04-1.52), THs (OR, 1.65; 95% CI, 1.15-2.37), and THs-OTO (OR, 1.98; 95% CI, 1.09-3.61) accounting for these differences, respectively. Overall mortality decreased (OR, 0.66; 95% CI, 0.47-0.94) following a decrease in the TH-OTO mortality rate (OR, 0.34; 95% CI, 0.12-0.93). Conclusions and Relevance While recurrent laryngeal nerve injury, hematoma formation, and hypoparathyroidism did not change, length of stay and mortality improved within THs-OTO following head and neck endocrine procedures after implementation of duty hour regulations. This finding refutes the concern that duty hour restrictions result in poorer overall outcomes. Less time available to develop technical competence may play a factor in some outcomes in lieu of recurrent laryngeal nerve injury increasing within THs and accidental injury to vessels, organs, or nerves and hypocalcemia increasing within THs-OTO. Furthermore, head and neck endocrine cases increased at THs with otolaryngology programs.

Objective. Traditionally, direct laryngoscopy confirms stage and tissue diagnosis prior to treatment planning. Patients who are frail or have tenuous airway anatomy may incur risks while undergoing anesthesia. Further, direct laryngoscopy is scheduled after initial examination, introducing diagnosis delay. This study investigates the impact of ultrasound examination with guided needle biopsy compared with traditional operative biopsy. Study Design. Case series. Setting. Tertiary head and neck clinic. Subjects and Methods. The records of patients at the Veterans Affairs Medical Center Memphis and Regional One Health who had supraglottic, oropharyngeal, and hypopharyngeal cancer that was diagnosed by ultrasound needle biopsy were reviewed from 2011 to 2016. Demographics, stage, biopsy results, and treatment were abstracted. Results. Seventeen patients who underwent ultrasoundguided needle biopsy of the primary site were included. Average age was 63 years old, and 65% of patients were stage T4 (11/17). Needle biopsy yielded malignant cells in 76% (13/17). Eleven patients were included in subsequent analysis because 6 patients underwent needle biopsy only. Fisher exact test showed no difference between the 2 methods (P = .27). Sensitivity was 86% and specificity was 100%. Seven patients had a median potential delay in diagnosis of 10 days. Conclusions. Ultrasound can be used effectively to obtain a tissue diagnosis, circumventing an operative biopsy. Moreover, ultrasound may provide additional imaging details to support accurate staging. This strategy may prove worthwhile to cut costs and reduce delay to staging, reduce risk for those with contraindications to anesthesia, and increase staging accuracy via enhanced imaging details.

Objectives/Hypothesis: Angioedema (AE) is a condition that may prompt a visit to an emergency department (ED), and can quickly progress to airway obstruction. To optimize treatment of AE, it is necessary to understand epidemiology and practice patterns. This study measured the magnitude of AE ED visits and characterized demographics, management, frequency of airway interventions, and mortality. Study Design: Analysis of two national data sets. Methods: From the Nationwide Emergency Department Sample and National Hospital Ambulatory Medical Care Survey, we identified all patients presenting from 2006 to 2010 with a primary diagnosis of AE, characterized by the International Classification of Diseases, Ninth Edition, Clinical Modification code 995.1. The discharges were weighted and stratified by comorbidities, age, treatments, and region. v2, t test, and linear regression were employed for comparisons. Results: Total discharges increased from 87,481 (29.3 of 100,000 people) to 111,116 (35.8 of 100,000 people). More females were afflicted (57%), and 41.1% were African American. The majority (83%) of patients were discharged from the ED. Twelve percent of cases were attributed to antihypertensive adverse reaction, and these patients were older (P < .0001, odds ratio [OR] 5 1.02), and had more comorbidities (P < .0001, OR 5 5.66), hospital admissions (P < .0001, OR 5 4.83), and intubations (P < .03, OR 5 2.07). Overall, patients required intubation infrequently (<1%) and mortality was low (0.08%). Conclusions: The AE burden on EDs has increased over time. Patients with adverse reactions to antihypertensives are older, have more comorbidities, and require admission and intubation more frequently. Further investigation is needed to better delineate causation and outcome predictors, and to understand regional practice variance.

Objectives/Hypothesis: Graduate medical education has traditionally required long work hours, allowing trainees little time for adequate rest. Based on concerns over performance deterioration with sleep deprivation and its effect on patient outcomes, duty hour restrictions have been mandated. We sought to characterize complications from otolaryngology key indicator procedures performed before and after duty hour reform. Study Design: Retrospective cross-sectional analysis of National Inpatient Sample (NIS). Methods: The NIS was queried for procedure codes associated with head and neck key indicator groupings for the years 2000–2002 (45,363 procedures) and 2006–2008 (51,144 procedures). Hospitals were divided into three groups: nonteaching hospitals (NTH), teaching hospitals without otolaryngology programs (TH), and teaching hospitals with otolaryngology programs (TH-OTO). Surgical complication rates, length of stay, and mortality rates were analyzed using logistic and linear regression. Results: The number of procedures increased (12.7%), with TH-OTO contributing more in postrestriction years (21% to 30%). Overall complication rates between the two periods revealed no difference, regardless of hospital setting. Subset analysis showed some variation within each complication within each grouping. Length of stay increased at TH-OTO (2.75 to 2.78 days) and decreased at NTH (2.28 to 2.24 days) and TH (2.39 to 2.36 days). Mortality did not increase among the three hospital types (NTH, P<.58; TH, P<.96; TH-OTO, P<.06). During the latter period, TH-OTO procedures showed lower mortality (P<.0038, odds ratio [OR]50.45, 95% confidence interval [CI]50.27-0.77). Increasing Charlson comorbidity index increased overall mortality rate (P<.0001, OR52.63, 95% CI52.4-2.89). Conclusions: Overall complication rates did not change for head and neck key indicator procedures. Moreover, concerns about reduced surgical case numbers appear unfounded, especially for otolaryngology programs.

Introduction Lateral pharyngotomy (LP) is a surgical procedure that allows exposure to tumors of the pharynx and supraglottic larynx. This study was undertaken to: (1) propose a classification system of LP used in exposing various sites of the oropharynx, supraglottis, and hypopharynx. (2) Describe the structures visible with each category of LP. Materials and methods Five tissue-fixed human cadavers from our gross anatomy laboratory were dissected in a manner similar to surgical lateral pharyngotomy. After exposure of the neurovascular structures of the anterior compartment of the neck and laryngeal framework, traditional pharyngotomy was performed with entry between the hypoglossal nerve cephalically and the superior laryngeal nerve caudally (traditional LP). Progressively increased exposure was created by division of adjacent structures. The ability to visualize certain structures (epiglottis, ipsilateral and contralateral base of tongue, postcricoid area, arytenoids, uvula, soft palate, and vallecula) through the pharyngotomy was recorded. Results The epiglottis and ipsilateral tongue base were visible via the traditional or Type I LP. Type II, III, and IV LP provided exposure to increasingly remote sites of the pharynx and supraglottic larynx. The additional exposure provided by each type of LP was consistent across all five cadaver specimens. Conclusion Our system catalogs the additional exposure of both cephalic and caudal tumor sites associated with division of adjacent structures. This anatomic study illustrates and systematizes the structures requiring division to provide access to a given tumor location.

Background: Polyurea crosslinked silica aerogels are highly porous, lightweight, and mechanically strong materials with great potential for in vivo applications. Recent in vivo and in vitro studies have demonstrated the biocompatibility of this type of aerogel. The highly porous nature of aerogels allows for exceptional thermal, electric, and acoustic insulating capabilities that can be taken advantage of for non-invasive external imaging techniques. Sound-based detection of implants is a low cost, non-invasive, portable, and rapid technique that is routinely used and readily available in major clinics and hospitals. Methodology: In this study the first in vivo ultrasound response of polyurea crosslinked silica aerogel implants was investigated by means of a GE Medical Systems LogiQe diagnostic ultrasound machine with a linear array probe. Aerogel samples were inserted subcutaneously and sub-muscularly in a) fresh animal model and b) cadaveric human model for analysis. For comparison, samples of polydimethylsiloxane (PDMS) were also imaged under similar conditions as the aerogel samples. Conclusion/significance: Polyurea crosslinked silica aerogel (X-Si aerogel) implants were easily identified when inserted in either of the regions in both fresh animal model and cadaveric model. The implant dimensions inferred from the images matched the actual size of the implants and no apparent damage was sustained by the X-Si aerogel implants as a result of the ultrasonic imaging process. The aerogel implants demonstrated hyperechoic behavior and significant posterior shadowing. Results obtained were compared with images acquired from the PDMS implants inserted at the same location.

Objectives: Describe the h index as a bibliometric that can be utilized to objectively evaluate scholarly impact. Identify which otolaryngology subspecialties are the most scholarly. Describe if NIH funding to one's choice of medical school, residency, or fellowship has any impact on one's scholarly output. Determine other factors predictive of an academic otolaryngologist's productivity. Study design: Analysis of bibliometric data of academic otolaryngologists. Methods: Active grants from the National Institutes of Health (NIH) to otolaryngology departments were ascertained via the NIH Research Portfolio Online Reporting Tools Expenditures and Reports database. Faculty listings from these departments were gleaned from departmental websites. H index was calculated using the Scopus database. Results: Forty-seven otolaryngology programs were actively receiving NIH funding. There were 838 faculty members from those departments who had a mean h index of 9.61. Otology (h index 12.50) and head and neck (h index 11.96) were significantly (P < 0.0001) more scholarly than the rest of subspecialists. H index was significantly correlative (P < 0.0001) with degree of NIH funding at a given institution. H index was not significantly higher for those that attended medical school (P < 0.18), residency (P < 0.16), and fellowship (P < 0.16) at institutions with NIH funding to otolaryngology departments. Conclusions: H index is a bibliometric that can be used to assess scholarly impact. Otology and head and neck are the most scholarly subspecialists within otolaryngology. NIH funding to an individual's medical school, residency, or fellowship of origin is not correlative with one's scholarly impact, but current institutional affiliation and choice of subspecialty are.
