Diagnostic Yield of Office-Based Laryngeal Biopsy in Patients With Leukoplakia; A Case Study With Review of the Literature

Abstract

Objective: To review the authors experience in un-sedated office-based biopsies of patients with vocal fold leukoplakia and to review the literature. Material and Method: A retrospective review of 29 patients was conducted. Results: A total of 41 office-based procedures were performed (eight patients had bilateral vocal fold lesions and four patients had the procedure performed twice). In 26 out of the 41 biopsies, the pathology revealed benign lesion. In eight cases, the pathology showed dysplasia (four high-grade and four low-grade). Seven biopsies revealed squamous cell carcinoma. Five patients underwent suspension micro-laryngoscopy for definitive diagnosis. Four of whom had a change in their diagnosis. Conclusion: Un-sedated office-based biopsy of vocal fold leukoplakia is an alternative to suspension microlaryngoscopy in case of carcinoma or nonmalignant lesions. © 2020
