ABSTRACT
OBJECTIVE:
Type III sulcus is a pathologic structural deformity of the vocal folds that is challenging to accurately diagnose without endoscopic examination under anesthesia. This study aims to further define the clinical presentation and examination features shared among a patient cohort intraoperatively diagnosed with type III sulcus. STUDYDESIGN:
Case series with chart review.SETTING:
Tertiary laryngology practice. SUBJECTS ANDMETHODS:
All patients diagnosed intraoperatively with type III sulcus from 2002 to 2014 at a tertiary laryngology practice were included. Clinical history of presenting symptoms, videostroboscopy, and intraoperative and histologic findings were reviewed.RESULTS:
Twenty-two patients were included in the study. A majority were female (77%) and had a mean age of 32.4 years. All patients endorsed hoarseness, and 86% were defined as professional voice users. Endoscopic examination revealed bilateral type III sulcus in 23% of patients. The most common preoperative stroboscopic findings included decreased mucosal wave (100%), dilated vessel (95%), phase asymmetry (91%), additional benign lesion (91%), and cyst (82%). Histology revealed epithelial changes of atypia and keratosis.CONCLUSION:
Both the severity of dysphonia and the difficulty observing structural malformations of the vocal folds make type III sulcus challenging to preoperatively diagnose. This study reports the clinical and endoscopic features seen within a cohort of patients with type III sulcus.Palavras-chave
