Abstract

Since the anatomy of vocal fold and physiology of phonation are introduced, many surgical techniques for vocal fold disorders has advanced. Microflap and mini-microflap surgery were designed to protect the bare surface of the operated site. However, many new techniques have been based on common sense because of the absence of an accessible animal model with a vocal ligament. Therefore, authors studied to evaluate the differences of the results between mini-microflap surgery and microdissection surgery. Thirty-four mini-microflap surgeries(17 bilateral) and twenty-eight microdissection surgeries(14 bilateral) were performed on 31 patients. Patients' subjective evaluation and videostrobolaryngoscopic examination revealed that mini-microflap surgery was better than microdissection surgery. A mini-microflap surgery, as does limited mucosal resection, was more efficacious in the treatment of vocal nodules than microdissection surgery.
