The Evaluation of Benign Glottic Lesions: A Prospective Diagnostic Comparison of Rigid Telescopic Stroboscopy and Suspension Microlaryngoscopy

The observation of benign glottic lesions in the office is generally made using rigid telescopic stroboscopy. However, the standard of care for diagnosis of glottic lesions entails suspension microlaryngoscopy in the operating room. The correlation of observed lesions between rigid telescopic stroboscopy in the office and suspension microlaryngoscopy has been investigated retrospectively. These prior studies have shown a disparity of between the office and intraoperative evaluations of benign glottic lesions. On some occasions, lesions observed intraoperatively led to different treatment outcomes than those obtained via stroboscopy. The different observations have implications regarding surgical consent, diagnostic accuracy, and patient satisfaction. The purpose of this study is to understand how often the diagnoses we obtain using the routine office-based procedure is enhanced or changed after the additional standard examination is completed in the operating room.

This study is a prospective observational study. Participants (males or females, ages 18-89) will be invited to join the study if they evidence a benign glottic lesion via rigid telescopic stroboscopy in the office. An exclusion criterion is prior operative intervention for benign vocal fold lesions. The nature and location of the lesion will be documented based on the office rigid telescopic stroboscopic examination as well as the intraoperative suspension microlaryngosocpy. Statistical methods will be used to compare on the nature and frequency of the different lesions observed between the two examinations.

This study will analyze the additional pathologies observed with suspension microlaryngosocpy, including the specific pathologies the frequencies with which they are observed. The frequency and change in management resulting from the differences observed with suspension microlaryngoscopy will be analyzed. The implications of this study include accurate and meaningful surgical consent processes, diagnostic accuracy, and patient satisfaction.
