- Abstract
Introduction: In this study, we aimed to investigate the findings of laryngeal electromyography (L-EMG) of organic and functional laryngeal pathologies affecting superior laryngeal nerve in patients with voice hoarseness. Methods: A complete laryngeal examination was performed with a routine ear-nose-throat examination and a 70-degree 4-mm telescope. L-EMG studies Dantec-KeyPoint (Medtronic-Denmark) was made with two channels of portable devices. For EMG, 20 mm bipolar concentric needle electrodes (myoline spes medica, Italy) were used. Local anesthesia was not performed due to the relative painlessness of the procedure and the thought that local anesthetics would affect the functions of the muscles. Cricothyroid muscle and thyroarytenoid muscle were tested by electromyography. Results: Twenty-four patients with voice hoarseness were included in the study. 11 (45.83%) of the patients were male and 13 (54.16%) were female. Their ages ranged from 15 to 57 years, with an average age of 37.62. Total of 96 muscles emg were made. L-EMG was pathologic in 15 patients (62.5%), three bilateral pathologic findings. 20 muscles were pathologically (20.8%), 14 with neurogenesis (70%), 4 (20%) weak activity, no activity, 2 (10%) showed dystonic activity. Eight of the right KT muscles (5 neurogenic, 2 weak activity, 1 activity not taken), 5 of the left KT muscles (2 neurogenic, 1 weak activity, 2 dystonic activity) pathologic. There were neurological involvement in the right TA 4 patients from the TA muscle, and 3 patients in the left TA 3 muscle. DISCUSSION AND CONCLUSION: It should be kept in mind that L-EMG may be an adjunctive application for neurogenic myogenic involvement that affects superior laryngeal nerve in the pathologic pathologies leading to hoarseness.
