Objective:
To explore the clinical effect on defect of post-laryngectomy partial laryngeal repaired with omohyoid myofascial flap.
Method:
Twenty-four cases of supraglottic and glottic cancer were treated surgically. The tumors and involved cartilages were removed entirely. The omohyoid myofascial flap was utilized to repair the defects of larynx and reconstruct the glottis. For the cases of unilateral fixation of arytenoid, the arytenoids were removed and replaced by a piece of omohyoideus linked to hyoid bone, then were covered with mucous. The cases above T2 supraglottic and T3 glottic received radiotherapy.
Result:
The following-up time is 1-5 years. One case of supraglottic cancer(T3) dies from local recurrence after operation for 2 years and 9 months. One case of glottic cancer(T3) dies from neck and bone metastasis after operation for 4 years and 3 months. Swallow function was preserved in all cases. The rate of deconnalation was 95.8%. 91.7% patients had laryngeal functions restored.
Conclusion:
For selected cases, using omohyoid myofascial flap to repair the partial laryngeal defect and reconstruct glottis is available and practicable.
