Suspension microlaryngoscopic surgery and indirect microlaryngostroboscopic surgery for benign lesions of the vocal folds

A prospective study was designed to compare the effects on voice capacities after either suspension microlaryngoscopic surgery or indirect microlaryngostroboscopic surgery. Patients where the clinical diagnosis ‘dysphonia due to a benign lesion of the vocal fold’ was made, and who could be operated in either way, entered the study. Post-operative voice evaluation was performed on 21 patients after suspension microlaryngoscopic or indirect microlaryngostroboscopic surgery. The long-term voice results following indirect microlaryngostroboscopic surgery and suspension microlaryngoscopic surgery demonstrate a statistically significant improvement for the maximum intensity, maximum dynamic intensity range, dynamic intensity range at habitual speaking pitch, and melodic pitch range. In selected cases indirect microlaryngostroboscopic surgery offers a very good functional result. © 1994, JLO (1984) Limited. All rights reserved.
