Objective To evaluate the long term therapeutic effect of vertical partial laryngectomy using reconstruction of modified sternohyoid muscle flap. Methods Thirty seven cases of T1 and T2 glottic cancer and superglottic cancer were treated with vertical partial laryngectomy.The laryngeal defect following partial laryngectomy was repaired with modified sternohyoid muscle flap in the same time.Results After 3-5 years of follow-up,the 3 and 5 years survival rate were 100% and 78.4% respectively.The decannulation rate was 94.6%(35/37).Vocal quality was good or moderate in all the patients.Conclusion complete resection of tumor and simultaneous preservation of respiratory and vocal function by partial laryngectomy are very important for improving patients life quality.With a suitable size and good blood supply,the modified sternohyoid muscle flap instead of the one with whole thickness is ideal in the reconstruction of laryngeal defect after vertical partial laryngectomy.
