[Conservative surgery for glottic cancer with vocal cord fixation (T3)].

OBJECTIVE

To study the method of reconstruction of laryngeal function by unilateral bi-pedicled and bi-muscular flaps for glottic cancer of T3 category.

METHODS

From 1984 to 1992, the unilateral bi-pedicled and bi-muscular flaps were used in 68 patients with T3 glottic cancer for repairing the surgical defect, enlarging the piriform recess on the affected side and closing the anterior wall of the laryngeal cavity after vertical laryngectomy.

RESULTS

The 5-year survival rate was 73.5% (50/68). The decannulation rate was 91.2% (62/68). sixty-three patients had satisfactory phonation (92.6%). All patients resumed mouth-food-taking within 7 to 20 days after operation.

CONCLUSION

The unilateral bi-pedicled and bi-muscular flaps are appropriate for reconstruction of surgical defect in T3 glottic cancer.
