Objective: To investigate the feasibility of modified frontolateral partial laryngectomy without tracheotomy for patients with early-stage laryngeal cancer or dysplasia of the true vocal cord.
Study design: After frontolateral partial laryngectomy, the inner side of the sternohyoid muscle was drawn into the laryngeal lumen to suture it to the incisal margin of the uninjured side and to the false vocal cord on the side of the lesion to ensure the safety without tracheotomy. A reverted sternohyoid fascial flap was used to cover the anterior area to form a new laryngeal lumen in the shape of a ladder.
Subjects and methods: A total of 65 patients with early glottic carcinomas or severe dysplasia of the true vocal cord were treated with modified frontolateral partial laryngectomy without tracheotomy. Ipsilateral false vocal cord flaps and cervical skin flaps were used in 63 patients and two patients respectively to reconstruct the defect.
Results: Deglutition and phonation were fully recovered after 7 to 10 days postsurgery. The only postoperative complication was subcutaneous emphysema noted in nine patients. The 1-, 3-, and 5-year survival rates were all 100 percent.
Conclusion: Modified frontolateral partial laryngectomy without tracheostomy is an effective surgical method for early glottic carcinomas and severe dysplasia of the true vocal cord.
