vocal process
Anterior projection of the arytenoid cartilage where the vocal ligament attaches. Common site of granuloma formation and contact injury in voice disorders.
Full Definition
The vocal process is the anteriorly directed projection of the arytenoid cartilage that serves as the posterior attachment point for the vocal ligament and vocalis muscle. This anatomic structure is critical for voice production as it allows for vocal cord tension adjustment and glottic closure. The vocal process is a frequent site of benign lesions including contact granulomas, which develop from trauma related to chronic coughing, throat clearing, or voice abuse. In head and neck oncology, the vocal process area must be carefully evaluated during laryngoscopy as early glottic carcinomas may extend to involve this region, affecting voice quality and treatment planning.
Usage
Usage note: Distinguish from vocal fold; specific anatomic landmark on arytenoid cartilage.
