OBJECTIVE: To observe the exposure of the vocal lesions under endoscopes of different angles and to contrast the endoscopes' influence on surgery.
METHOD: Fifty patients with benign vocal lesions were selected randomly. During microlaryngoscopic surgery, the laryngoscope was placed softly and the different rigid endoscope (30 degrees, 45 degrees or 70 degrees) was connected to video system to expose the glottis and vocal folds. The operation was taken through looking at the color monitor.
RESULT: The vocal fold lesions were completely examined and successfully excised in all patients, only two of them got soft palate mucosal abrasion. No one got complications.
CONCLUSION: Rigid endoscopy associated with microlaryngeal surgery brings a better observation to the vocal lesions and a lower incidence rate of complicatons. It's regarded that 45 degrees rigid endoscope is better than the others, for it provides not only a good exposure to the vocal cords, anterior commissure and subglottis, but also convenience to operate. The second one is 30 degrees rigid endoscope, which can save the cost, because of the widely using in many other departments.
