[Analysis of mono-side sternohyoid myo-osteal flap used in reconstruction after partial laryngectomy].

OBJECTIVE

To evaluate the reconstruction effect and to investigate applied indication of unilateral sternohyoid muscle flap with hyoid bone in laryngeal carcinoma after partial laryngectomy.

METHOD: Seventy-three identified cases have been analysed by retrospective process. Statistic data mainly include postoperative eating condition, decannulation rate and postoperative voice. Detailed data of decannulation rate have been contrasted in different clinical stages, clinical types and operation types of malignant tumor. More data include three year, postoperative complications and so on.

RESULT: There are about 79.5% cases survived three years or more. All the cases can take food by mouth without gastric tube after the operation, 12.9 days in average. The total decannulation rate is 76.7% and difference is found between enlarged-vertical hemilaryngectomy and the other types of operations. More than 83.6% patients can speak in a nearly normal way.

CONCLUSION

The decannulation rate, voice and swallowing function are all recovered satisfactory after the reconstruction and the decannulation rate is not influenced by clinical stage or else of laryngeal carcinoma, but only by the range of ectomy. The mono-side sternohyoid muscle flap with hyoid bone can restore a baggish defect of larynx, and the survival rate is satisfied. It can take the place of full laryngectomy in some T3 or T4 cases whose extent of disease laid particular emphasis on one side.
