title: Acoustic measures of phonatory improvement secondary to treatment by oral corticosteroids in a professional singer: a case report.
abstract: Short-term administration of corticosteriods is sometimes indicated for professional voice users experiencing laryngeal edema and/or inflammation. Unfortunately, no data are available to document the effectiveness of these medications to improve phonatory parameters. We present a case report of a 32-year-old male professional singer with vocal fold edema experiencing imminent vocal demands who was prescribed a 6-day course (dose-pack) of oral methyl prednisolone. Endoscopic and stroboscopic evaluations were completed premedication and postmedication, and acoustic measures of phonatory function were obtained premedication, 3 days during the dose cycle, 5 days during the dose cycle, and 1 day postmedication. Postmedication results revealed an increase in fundamental frequency (F0) and large decreases in jitter, shimmer, long-term frequency, and amplitude variability. These corresponded with patient and evaluator perceptual measures of improved voice, and with endoscopic observations of reduced edema. The benefits and risks of corticosteroid therapy are discussed, specific to their use in the professional voice population.
