ABSTRACT
OBJECTIVE: Investigate the response of the patients with obstructive sleep apnea hypopnea syndrome (OSAHS) patients to combination of transpalatal advancement pharyngoplasty and uvulopalatopharyngoplasty. METHODS: Thirty two patients with OSAHS, age ranged from 27 to 54, mean value (x +/- s) 39.1 +/- 7.8, male, body mass index (BMI) ranged from 22.9 to 36. 7 kg/m2, mean value (29.0 +/- 3.6) kg/m2, preoperative apnea and hypopnea index (AHI) was 11.7/h to 113.7/h, mean value (61.8 +/- 21.9)/h, the lowest blood oxygen saturation was 0.10 to 0.85, mean value 0.64 +/- 0. 13. With preoperative endoscopic technique, bony nasopharynx cavity narrowing were present, 14 patients had concomitant tonge-base obstruction. Cephalometric result, SNA ranged from 72.9 degrees to 87.0 degrees, mean value (80.7 +/- 4.1) degrees; SNB 69.50 to 85.0 degrees, mean value (76.8 +/- 4.5) degrees; PAS 0.5 cm to 2.1 cm, mean value (1.2 +/- 0.5) cm; MP-H: ranged from 1.2 cm to 3.5 cm, mean value (2.2 +/- 0.7) cm; PNS ranged from 2.4 cm to 3.5 cm, mean value (2.8 +/- 0.4) cm. All the patients had H-UPPP and concomitant transpalatal advancement pharyngoplasty. Fourteen patients with tonge-base obstruction had chin advancement. Results Six months after the operations, the patients were evaluated the response to the operations using Epworth sleep scale, OSAHS filtration questionnaire scale and polysomnography (PSG). There were 27 patients with the decrease percent of AHI reaching or more than 25% and 22 patients with the decrease percent of AHI reaching or more than 50% including 8 patients with AHI less than 5. The other 5 patients were ineffective. After operation, the Epworth sleep scale decreased from (9.2 +/- 4.5) to (4.7 +/- 2. 8) and OSAHS filtration questionnaire scale decreased form (56.0 +/- 15.3) to (17.5 +/- 11.5). Both of the differences were obvious (P < 0.01). CONCLUSIONS: Combination of transpalatal advancement pharyngoplasty and H-UPPP can improve the efficacity and in some patients with pure retropalatal airway narrowing, the cure rate can be improved.
