Özet
OBJECTIVES: This study aims to identify patients with benign vocal cord lesions using laryngeal electromyography (EMG) and to investigate the presence of accompanying vocal cord paresis.PATIENTS AND METHODS: Twenty-eight patients (18 males and 10 females; mean age 38.6±10.2 years; range 22 to 59 years) who were diagnosed with benign vocal cord lesion using a rigid laryngostroboscopy underwent laryngeal EMG and the presence of neurogenic involvement was investigated.RESULTS: Laryngostroboscopic examination revealed polyp in 85.7% (n=24), Reinke's edema in 10.7% (n=3), submucosal cyst in 10.7% (n=3), and contact granuloma in 3.6% (n=1). Of the patients, 14.2% (n=4) were suspected to have vocal cord paresis. Laryngeal EMG revealed neurogenic involvement in at least one of the larynx muscles in 57.2% (n=16) of the patients. Eight patients (28.6%) had unilateral neurogenic involvement, while three (10.7%) demonstrated isolated recurrent laryngeal nerve paresis two (7.2%) demonstrated isolated superior laryngeal nerve paresis, and three (10.7%) demonstrated combined recurrent and superior laryngeal nerve paresis. Six (21.4%) of eight patients with bilateral neurogenic involvement had paresis in three laryngeal nerves, whereas in two (7.2%) patients four laryngeal nerves were affected.CONCLUSION: Our study shows that vocal cord paresis frequently accompanies benign vocal cord lesions. Laryngeal EMG is useful to identify clinically suspected or unsuspected paresis with physical examination precisely.
