IntroductionSulcus vocalis is an epithelial invagination along the free edge of the membranous vocal fold. It interferes with the glottic closure and vibration pattern. Sulcus vocalis provokes voice fatigue, hoarseness and breathiness, and it usually appears in association with hyperkinetic phonatory pattern. Hyperkinesis develops secondarily, due to the compensatory effort to overcome the deficiency in glottic closure. The treatment of sulcus vocalis is very difficult. Phonosurgery is used, and is followed by postoperative voice therapy.Phonosurgical OperationsVarious surgical techniques are used in the therapy of sulcus vocalis. Over a 10-year period we have operated on 1550 patients with benign lesion of the vocal folds, of whom only 11 had sulcus vocalis (0.7%). We carried out various surgical techniques. a) Excision of sulcus A longitudinal incision of mucosa is performed along the upper surface of the vocal fold, distant of the free edge. Mucosa is undermined caudally, and sulcus is detached from its base. Sulcus is then removed by surgical scissors. With this technique we could not provide physiological phonation and vibration pattern, in spite of an apparent improvement in the voice. b) "Slicing mucosa" technique This procedure was suggested by Pontes, and it also begins with a longitudinal incision followed by creation of inferiorly based slices of mucosa. c) Excision plus rhyroplasty Excision of sulcus is combined with thyroplasty type I in order to achieve medialization of the vocal fold. It can be used in cases with severe glottal gap in order to improve the results of excision. d) Implants Various materials were used in order to enlarge the mass of the vocal fold. In our patients, the results of this procedure were inferior as related to excision surgery.DiscussionThe surgical procedure which is safe and accepted by the majority of surgeons has not yet been at our disposal. The treatment of sulcus vocalis should start with voice therapy, which lasts as long as the patient shows a progress. Only then the surgical procedure can be discussed. We obtained the best results with the combination of excision and voice therapy. However, the surgeon and the patient must be aware that the treatment is demanding and long-lasting.
