Abstract

OBJECTIVE:

To investigate the complications of tongue base reduction with radiofrequency tissue ablation on patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and find out the effective prevention strategies.

METHODS:

One hundred and ninety three OSAHS patients diagnosed by polysomnography were received tongue base reduction with radiofrequency tissue ablation between March 2008 and December 2009. The intraoperative and postoperative complications including bleeding, hematoma of tongue base, abscess of tongue base, altered taste, tongue numbness, deviation of tongue extension movement, dysfunctions of pronunciation and swallowing as well as the managements were analyzed retrospectively.

RESULTS:

No perioperative complications occurred. There were 186 cases with postoperative pain (96.4%), 155 cases with submandibular edema (80.3%). Nocturnal sudden cardiac death was encountered in 1 case and secondary bleeding in 1 case. There was no ulceration of tongue base mucose, hematoma or abscess of tongue base, altered taste, tongue numbness, tongue deviations, speech, swallowing and taste disorder after operation. The scale of postoperative pain claimed by patients was ranged between mild to moderate. Diclofenac suppository had analgesic effect for these patients. The quantity of bleeding in patient with secondary hemorrhage was so little that after proper treatment the bleeding was stopped and never happened again. Patient with nocturnal sudden cardiac death occurred at thirty-seven hours after operation, because of swelling and pain of tongue base aggravated sleep apnea and night hypoxemia inducing fatal arrhythmia.

CONCLUSIONS:

Postoperative pain and submandibular edema were 2 most common postoperative complications which can be easily controlled by antibiotics, Glucocorticoids and Diclofenac suppository. For those severe OSAHS patients accompanied by cardiopulmonary diseases, the tongue base reduction with radiofrequency tissue ablation can induce nocturnal sudden cardiac death. It is important to pay more attention on arrhythmias at night in severe OSAHS patients.
