Analysis of degree of incidence of small anatomic anomalies of larynx among dysphonia patients

Abstract

The disturbance of the voice function is a socially significant problem. Small anatomical anomalies (SAA) along with organic causes of impaired voice function can cause dysphonia. Disturbances of the voice in the presence of SAA belong to little studied and persistent dysphonias. Information about the prevalence of this group of anomalies in domestic and foreign literature is few and controversial. Objective: to determine the incidence of SAA of the larynx in patients with dysphonia. Materials and methods: Retrospectively were analyzed the 58 case histories of patients who were diagnosed with functional dysphonia in the clinic of diseases of ear, nose and throat of Sechenov First MSMU from 01.09.2011 to 01.10.2015. Patients underwtent videostroboscopic and fibrolaryngoscopy studies. Results: Average age 37 ± 6 years, women-37 (64%), men – 21 (36%). In 27 (47%) patients spastic dysphonia was diagnosed, 23 (39%) – dysphonia hipotenusa, 7 (12%) – mutational dysphonia, only 1 (2%) patient in the course of stroboscopic studies was diagnosed with SAA - grooves of both vocal folds. Conclusions: the SAA of the larynx are small and the prevalence with early detection and treatment can produce favorable prognosis. However, being a disease with unknown etiology and prevalence until the end and if untreated can lead to adverse consequences and should not remain undiagnosed. It should be kept in mind during differential search to find out the cause of dysphonia.
