[Thyroid cartilage flap reconstruction of cricoid in the management of subglottic carcinoma].
OBJECTIVE
To evaluate the effect of conservative surgical management on patients with subglottic cancer.


METHODS
Nine cases with subglottic carcinoma were treated surgically from 1984 to 1999. There were T2N0 lesions in 2 cases, T3N0-1 in 3 cases and T4N0-1 in 4 cases. All the cases underwent partial laryngectomy including partial cricoid resection. Variations of a pedicled thyroid cartilage flap were used for reconstruct the cricoid defect. The pedicle based muscle was thyrohyoid, sterno-thyroid or inferior constrictor. Unilateral neck dissection was performed on 7 cases and bilateral on two.


RESULTS
The function of phonation were preserved in all cases. Eight of nine 8/9 were decanulated. Normal deglutition were achieved for all patients. The 3 and 5 year survival rates were 8/9 and 6/9, respectively.


CONCLUSIONS
Pedicled thyroid cartilage flap is appropriate for reconstruction of the cricoid defect in the conservative surgery of selected subglottic carcinoma.
