Objective:
To evaluate the prospective effect and minimize the postoperative trauma of applying the central suspension operation of hyoid and lower jaw for the treatment for OSAS in 28 cases.
Method:
The data of 28 patients with obstructive sleep apnea syndrome(OSAS) operated with central suspension operation of hyoid and lower jaw and uvulopalatopharyngoplasty(UPPP) were analyzed.
Result:
One case (3.6%) reported unchanged snoring and apnea and hyponea index. Twenty-seven cases (96.4%) improved after the operation for at least 6 months to 3 years. The complications include tonsil bleeding (1 case), suffocation after extraction of endotracheal tube (1 case), temporal tongue insufficiency (1 case).
Conclusion:
On the previous basis of UPPP, we emphasize the protection of pharynx muscles and adjusting the position. The central suspension operation of hyoid and lower jaw not only increases the curative effect in the long run, but also avoids the tracheotomy.
