Abstract
BACKGROUND: Radial extracorporeal shock wave therapy (r-ESWT) is commonly used for the treatment of chronic plantar fasciitis. Previously in the urology literature, some studies reported hearing impairment after extracorporeal shock wave lithotripsy. However, there is no study that evaluates the possible side effects of r-ESWT on the hearing function of patients. The aim of this study was to investigate the effects of r-ESWT on the pure tone audiometry of the patients on whom r-ESWT was applied for chronic plantar fasciitis. MATERIAL AND METHODS: Patients with the diagnosis of plantar fasciitis who were treated with r-ESWT were included in this prospective case-control study. Before and after the r-ESWT application, all patients were consulted to our otolaryngology department for pure tone audiometric examination to detect any hearing impairment before and after the treatment. A control group was also constructed that consisted of patients who were admitted to our department for any complaint. RESULTS: A total of 67 patients participated in the study. Radial ESWT group consisted of 47 patients (39 female, 8 male) with the mean age of 44.1 years. The control group consisted of 20 patients (12 female, 8 male) with the mean age of 36.9 years. We observed a 20-dB threshold shift at 8000Hz in 1 patient who had no clinical symptom. This patient had no threshold shift at the 1-month control audiometric measurement. CONCLUSION: According to the results acquired from this study, we can consider that r-ESWT treatment in patients with chronic plantar fasciitis has no markedly detrimental effect on the hearing function.
