Objective: Given high COVID-19 viral load and aerosolization in the head and neck, otolaryngologists are subject to uniquely elevated viral exposure in most of their inpatient and outpatient procedures and interventions. While elective activity has halted across the board nationally, the slow plateau of COVID-19 case rates prompts the question of timing of resumption of clinical activity. We sought to prospectively predict geographical "hot zones" for otolaryngological exposure to COVID-19 based on procedural volumes data from 2013 to 2017. Read More

Objective: Smoothed cepstral peak prominence (CPPs) has been shown to be an effective indicator of breathiness (Hillenbrand and Houde, 1996). High-speed videoendoscopy (HSV) is frequently being used as a complement to stroboscopy especially when asymmetric or aperiodic vocal fold vibration is present in dysphonic voices. In an HSV image data set obtained with normal (nondisordered) voice subjects, we have observed that some degree of asymmetry is present in many of the vocal fold displacement curves extracted from the HSV exam videos; therefore, we have used this data set for a pilot study to investigate the relationship of CPPs to cyclical vocal fold vibration parameters, including left-right vocal fold (LVRF) phase asymmetry, in subjects with normal (nondisordered) voices.

Objectives/hypothesis: We previously developed an instrument called the Aerodynamic Vocal Fold Driver (AVFD) for intraoperative magnified assessment of vocal fold (VF) vibration during microlaryngoscopy under general anesthesia. Excised larynx testing showed that the AVFD could provide useful information about the vibratory characteristics of each VF independently. The present investigation expands those findings by testing new iterations of the AVFD during microlaryngoscopy in the canine model. Read More

The stroboscopic effect made by helicopter blades passing through rays of sunlight is known as a factor that can induce an epileptic seizure. We report a case of inaugural tonic-clonic generalized seizure while refueling an NH 90 helicopter by an aeronautical technician standing under the rotating main rotor on a sunny day at a South of France naval air station. The stroboscopic effect of the helicopter blades was identified as one of the factors involved in the induction of this seizure. Read More

Methods: We prospectively collected data from a cohort of 204 consecutive patients newly presenting for ambulatory laryngology evaluation. Each patient completed the VHI-10 and 16 concurrent mainstream queries about vocal characteristics such as weakness, breathiness, fatiguability, or inability to shout. Read More

Pediatric dysphonia is common; however, not all vocal fold pathology in children is due to nodules. Laryngeal stroboscopy (transoral or transnasal) often is essential for the diagnosis of other not-nodule lesions. As in adults, multidisciplinary care with a speech language pathologist helps with patient buy-in for therapy. Read More

Dysphonia is often blamed on laryngopharyngeal reflux (LPR) in the face of a normal flexible laryngoscopic examination. LPR remains primarily (and unfortunately) a diagnosis of exclusion rather than inclusion in the face of vague throat complaints and laryngeal signs attributed to reflux. LPR remains misdiagnosed and overdiagnosed as the cause of many identical, vague throat symptoms and laryngeal complaints. Read More

Presbyphonia is defined as aging of the voice, and its growing attention as a medical concern parallels the continuing increase of the geriatric population worldwide. It results from physiologic changes to several laryngeal structures, including the musculature, surrounding cartilage, and lamina propria of the vocal folds. Characterized by glottic insufficiency, dysphonia in the elderly typically presents as a deterioration of voice quality, altered pitch and fundamental frequency, vocal fatigue, and strain. Read More
