Abstract: Objective:To investigate the feasibility of raising the rate of extubation by enlarging the glottis or treating pa -tients without tracheostomy in modified frontolateral partial laryngectomy. Methods:A total of81patients with glottic carci-noma were included. There were 54T1 stage cases, 25T2 stage cases, and 2 cases with severe atypical hyperplasia in the lateral vocal cord. After frontolateral partial laryngectomy, the false vocal cord was drawn to the hypolarynx on the side of the lesion. The inner side of sternohyoid muscle was drawn into the laryngeal lumen and sutured to the incisional margin of the inner side of the laryngeal lumen. A reverted fascial flap was used to cover the anterior area to get a large laryngeal cav -ity, resulting in a ladder-shape laryngeal lumen. Results: The incision healed well in all patients. Sixty-five cases were treat-ed without tracheotomy. Thirty-nine patients had postoperative subcutaneous emphysema. All patients were discharged at 7 to 15days after surgery. Only 2 patients died at 1 to 2 years after surgery. Conclusion:The section area of laryngeal cavi-ty can be enlarged by modified laryngoplasty and some patients can even be treated without tracheostomy. Modified fronto -lateral partial laryngectomy can be used in patients after vertical partial laryngectomy, patients with laryngeal stenosis and those who cannot tolerate extubation.
