Nasal septal abscesses (NSAs) occur between the mucoperichondrium and the nasal septum. They most often arise when an untreated septal hematoma becomes infected. The most commonly reported sequela is a loss of septal cartilage support, which can result in a nasal deformity. Other sequelae include potentially life-threatening conditions such as meningitis, cavernous sinus thrombosis, brain abscess, and subarachnoid empyema. We report the case of a 17-year-old boy who developed an NSA after he had been struck in the face with a basketball. He presented to his primary care physician 5 days after the injury and again the next day, but his condition was not correctly diagnosed. Finally, 7 days after his injury, he presented to an emergency department with more serious symptoms, and he was correctly diagnosed with NSA. He was admitted to the intensive care unit, and he remained hospitalized for 6 days. Among the abscess sequelae he experienced was septic arthritis, which has heretofore not been reported as a complication of NSA. He responded well to appropriate treatment, although he lost a considerable amount of septal cartilage. He was discharged home on intravenous antibiotic therapy, and his condition improved. Reconstruction of the nasal septum will likely need to be pursued in the future.

ObjectiveVoice outcomes following medialization laryngoplasty (ML) for unilateral vocal fold paralysis (UVFP) were compared to those who underwent ML plus arytenoid adduction (AA) (ML+AA).MethodsSingle institution retrospective review of patients with UVFP undergoing ML and ML+AA (2009–2017). Demographic information and history of laryngeal procedures were collected. Preoperative and postoperative Voice Handicap Index‐10 (VHI‐10) and Consensus Perceptual Auditory Evaluation of Voice (CAPE‐V) were assessed.ResultsOf 236 patients, 119 met study criteria. Of those, 70 (59%) underwent ML and 49 (41%) underwent ML+AA. Significant differences between groups at baseline were found for age at time of thyroplasty (P = 0.046), VHI‐10 scores (P < 0.001), and CAPE‐V scores (P = 0.007). Baseline VHI‐10 scores for ML+AA (28 ± 7) were greater than those for ML alone (24 ± 7). At 12 months, overall VHI‐10 scores improved compared to baseline for both groups (ML+AA = 9 ± 7, ML = 16 ± 9); however, there was greater improvement for the ML+AA group compared to ML group (P = 0.001). CAPE‐V scores at 3 or 12 months improved, but differences between the groups were not statistically significant once controlled for covariates.ConclusionBased on current findings, patients who undergo ML+AA likely have greater voice handicap at baseline compared to those undergoing ML alone. Patients selected for ML+AA improve as much or more than those who underwent ML alone. This highlights the importance of appropriate selection of candidates for AA.Level of Evidence4Laryngoscope, 129:1876–1881, 2019

Objectives/HypothesisTo evaluate trends, outcomes, and healthcare utilization following medialization laryngoplasty (ML) with or without arytenoid adduction (AA) over 10 years.Study DesignRetrospective observational study.MethodsUsing OptumLabs Data Warehouse, trends, outcomes, and healthcare utilization from 2006 to 2015 were examined with a focus on discharge type (same day or not). Predictors of postoperative emergency department (ED) use and hospitalization were determined by multivariable logistic regression.ResultsOverall rate of ML was 1.09 per 100 thousand enrollees per year. Of these, 7.8% ML were combined with an AA. Outpatient same‐day discharge represented 62.0% (1,142 of 1,843) of total patients, steadily increasing over the 10‐year period (P < 0.01). There was a 5.9% revision ML rate and 1.0% rate of tracheotomy within 1 day of ML. A total of 5.6% visited an ED, and 5.4% were admitted to a hospital following initial discharge within 30 days. Same‐day discharge was found to be a predictor of hospitalization within 30 days after ML (odds ratio [OR] 1.74, P = 0.0452), along with Elixhauser comorbidity index of 4 + (OR 5.74, P = 0.0001). Pulmonary embolism, pulmonary hypertension, and weight loss were top predictors of ED visit or hospitalization.ConclusionTo our knowledge, this is the first search evaluating national claims data for ML with or without AA. Overall rate of ML is low, and same‐day discharge has become more common over a 10‐year period, with an associated higher 30‐day hospital admission risk. Correct patient selection criteria for disposition status cannot be fully determined based on current data, but a high Elixhauser comorbidity index clearly carries increased risk for hospitalization after initial discharge.Level of Evidence4 Laryngoscope, 129:952–960, 2019

Objectives/HypothesisVocal fold (VF) paralysis by sectioning the recurrent laryngeal nerve dramatically impacts the life of thyroidectomy patients. Volume‐expanding materials can temporarily restore VF medialization. To prolong this benefit, adipose mesenchymal stem cells (ADSCs) and micronized acellular dermis (MACD) were co‐injected in a rabbit model of injection medialization laryngoplasty. Biomarkers of in situ proliferation were identified by mass spectrometry proteomics and pathway analysis to guide future efforts to increase the length of benefit.MethodsADSCs were expanded and/or differentiated into chondrocytes (CHON) as collagen microspheres. After VF paralysis rabbits received MACD, MACD + undifferentiated ADSC, or MACD+CHON, ADSCs differentiated into chondrocytes. After 12 weeks, animals were sacrificed and 5‐µm paraffin‐embedded cryosections were prepared from larynges for hematoxylin and eosin visualization and nanoflow liquid chromatography electrospray‐ionization tandem‐mass spectrometry analysis of tissue collections. Validated proteins were processed by Venn subtraction and gene ontology (GO) overrepresentation analysis to identify unique pathways and biomarkers.ResultsConfirmed proteins numbered 147 (MACD), 1,243 (MACD+ADSC), and 1,033 (MACD+CHON). Totally, 333 proteins were uniquely found in the MACD+ADSC group, including mesenchymal surface markers CD9, CD44, fibronectin, and vimentin. Over 70% of proteins belonged to catalytic activity and binding GO categories, with the histone (H) family being overrepresented (P < 0.05). Histone variants H3.3, H2A.V, and H2A.Z (associated with open chromatin states) were overrepresented in the MACD+ADSC group, whereas structural histones H2A, H2B, and H4 were not.ConclusionBiomarkers, including atypical histones, are associated with in vivo proliferation of ADSCs and an expanded VF medialization volume.Level of EvidenceNA Laryngoscope, 128:E402–E408, 2018

Objective: Vocal cord dysfunction (VCD) is characterized by paradoxical vocal fold movement (PVFM) during inspiration. The aim of this study was to determine whether ultrasound could accurately differentiate between normal and PVFM during respirations in a resting state. Design: Prospective, single-subject design. Setting: Academic medical center. Patients: A speech-language pathologist who was able to volitionally alternate between normal and PVFM when breathing at rest was recruited to participate in the study. Interventions: The subject was instructed to randomly alternate between normal and PVFM 20 times (10 times each). A single investigator imaged the vocal folds using ultrasound and reported when the subject alternated between the 2 respiratory states. Main Outcome Measures: The subject recorded when they changed between the 2 respiratory states, whether the investigator identified with the change occurred, and if the correct respiratory state was identified. Results: The investigator recognized when the subject changed respiratory states and correctly identified the new respiratory state 100% of the time. Conclusions: The findings of the current study were promising and suggest that ultrasound may have utility in the diagnosis of VCD. However, because of the preliminary nature of these results, further research is required before recommending its clinical implementation.

Introduction. Idiopathic subglottic stenosis represents a spectrum of subglottic disease without a clear underlying cause. Prior studies have implicated a pathogenic role of gastroesophageal reflux disease in idiopathic subglottic stenosis. The aim of this study was to examine the presence and pattern of gastroesophageal reflux in a large cohort of patients with idiopathic subglottic stenosis at a tertiary referral center. Methods. We performed a retrospective review of patients with idiopathic subglottic stenosis from January 2010 to December 2016 who had undergone combined pH impedance testing. Patients with prior gastric or esophageal surgery were excluded. Data obtained included esophageal acid exposure times, number of reflux events, patient position during reflux events (defined as upright, supine, or mixed), body mass index, and the presence of proton pump inhibitor therapy. Results. 159 patients with the idiopathic subglottic stenosis were identified, of whom 41 had undergone esophageal pH impedance testing. 40 (97.6%) were women, with a mean age of 54.8 (range 31–79) years and BMI of 31.0 (range 17–55). Overall, 19 (46.3%) patients were found to reflux as confirmed by abnormal esophageal acid exposure or abnormal number of reflux events. 15 of the 19 patients with reflux had predominantly upright gastroesophageal reflux disease, whereas 2 had supine and 2 mixed reflux. Discussion. In patients with idiopathic subglottic stenosis who underwent evaluation by combined pH impedance, close to half were found to have gastroesophageal reflux disease. The majority of gastroesophageal reflux occurred while the patients were in the upright position.
