Abstract

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.

Özet

Amaç: Bu çalışmada benign vokal kord lezyonu bulunan hastalar larengeal elektromiyografi ile (EMG) değerlendirildi ve eşlik eden vokal kord parezisi varlığı araştırıldı. Hastalar ve Yöntemler: Rijit larengostroboskop ile benign vokal kord lezyonu saptanan 28 hastaya (18 erkek, 10 kadın; ort. yaş 38.6±10.2 yıl; dağılım 22-59 yıl) larengeal EMG yapıldı ve nörojenik tutulum varlığı değerlendirildi. Bulgular: Larengostroboskopik muayenede hastaların %85.7sinde (n=24) polip, %10.7sinde (n=3) Reinke ödemi, %10.7sinde (n=3) submüköz kist, %3.6sında (n=1) kontakt granülom vardı. Hastaların %14.2sinde (n=4) muayenede vokal kord parezisinden şüphelenildi. Larengeal EMG değerlendirilmesinde hastaların %57.2sinde (n=16) bir veya birden fazla larenks kasında nörojenik tutulum bulgusu saptandı. Hastaların sekizinde (%28.6) nörojenik tutulum tek taraflı iken, üçünde (%10.7) izole reküren larengeal sinir parezisi, ikisinde (%7.2) izole süperior larengeal sinir parezisi ve üçünde ise (%10.7) kombine tek taraflı reküren ve superior larengeal sinir parezisi vardı. İki taraflı nörojenik tutulum olan sekiz hastanın (%28.6) altısında (%21.4) üç larengeal sinirde, ikisinde (%7.2) ise dört larengeal sinirde nörojenik tutulum saptandı. Sonuç: Bu çalışmada vokal kord parezisinin benign vokal kord lezyonlarına yüksek oranda eşlik edebileceği gösterilmiştir. Larengeal EMG klinik olarak şüphe edilen veya muayenede şüphelenilmeyen parezinin kesin olarak tanınmasını sağlar.
