Outcome comparison of two methods of pharyngeal cavity reconstruction in uvulopalatopharyngoplasty

Conclusions: The efficacy of uvulopalatopharyngoplasty (UPPP) can be achieved without application of an apposition suture of the palatopharyngeal arch and the palatoglossal arch. Objective: To compare the outcomes of two different methods of pharyngeal cavity reconstruction in UPPP. Methods: Forty-eight patients with obstructive sleep apnoea syndrome (OSAS) underwent UPPP (uvula-preserving). A classical pharyngeal cavity reconstruction was performed in 24 patients in group one, with plastic suture of the inferior nasopharynx and exposure of the tonsillar fossa in 24 patients in group two. The parameters evaluated were the subjective symptom score, the Epworth Sleepiness Scale (ESS), and polysomnography result. The mean operating times and complications of the post-operative pharyngeal cavity were investigated. Results: No significant difference was observed in surgical success (p?=?0.54), subjective syndromes (snoring, sleep apnoea, morning headache, daytime sleepiness) (p?=?0.16, 0.36, 0.79 and 0.52), ESS (p?=?0.41), apnoea-hypopnoea index (AHI) (p?=?0.32), and minimum SaO₂ (p?=?0.13) between the two groups. In group one, the mean operating time was 54.72?±?6.52?min, 11 suture dehiscence (45.8%), and five scar hypertrophy of the pharyngeal wall (20.8%) were observed post-operatively; while in group two was 38.78?±?5.75?min, no suture dehiscence resulting from suture cutting of tissue, three scar hypertrophy were observed (12.5%).     

阻塞性睡眠呼吸暂停低通气综合征患者手术前后口咽腔测量分析

OBJECTIVE: To explore the relationship between the extent of enlarged oropharynx and efficiency through measuring the anterior-posterior and transverse diameter of oropharynx of patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) before and after uvulopalatopharyngoplasty (UPPP). METHODS: Thirty eight patients with OSAHS were studied. The following indexes were measured before and after UPPP: width of uvula base, length of uvula, distance between uvula and posterior pharyngeal wall (DBUP), distance between anterior pillar (DBPP), apnea-hypopnea index (AHI), body mass index (BMI) and SaO2. RESULTS: The preoperative DBAP and DBPP were significantly less than those of normal adults (P < 0.05). DBUP, length of uvula and width of uvula base has no significant difference between preoperative patients and normal adults (P > 0.05). There was no significance difference in DBAP. DBPP and DBUP between postoperative patients and normal adults (P > 0.05). The preoperative AHI, IBM, minimal SaO2, mean SaO2, DBUP, DBPP, DBAP, length of uvula and width of uvula base has no significant difference between good responders and nonresponders (P > 0.1). CONCLUSIONS: Transverse diameter of OSAHS patients is shorter than that of normal adults but anterior-posterior diameter of OSAHS patients has no difference compared with normal adults. Transverse diameter could be enlarged by UPPP. Not only anatomical abnormality but also other factors will contribute to the effect of UPPP.

Associated predictors of therapeutic response to uvulopharyngopalatoplasty for severe obstructive sleep apnea hypopnea syndrome

The aim of this study was to determine the associated factors affecting the outcome of uvulopharyngopalatoplasty (UPPP) in patients with severe obstructive sleep apnea hypopnea syndrome (OSAHS), and to investigate whether cephalometric measurements were predictive of the therapeutic response to UPPP in patients with severe OSAHS. We retrospectively studied 51 consecutive patients who underwent revised UPPP with uvula preservation (H-UPPP), or Z-palatopharyngoplasty (ZPPP) for severe OSAHS [apnea–hypopnea index (AHI) >30]. All patients were evaluated using physical examination, Epworth Sleepiness Scale (ESS), cephalometry, and nocturnal polysomnography (PSG) before surgery and at 6–12 months after surgery. Based on the success criteria defined as an AHI of <20 and a decrease >50 %, the overall success rate was 45.1 %. The preoperative distance from the posterior border of the uvula to the middle pharyngeal wall (U-MPW) was significantly longer in the responder group than in the nonresponder group, when considering the whole group or the H-UPPP group alone. Among all study subjects, U-MPW and change in body mass index (△BMI) were the significant predictors of surgical success. U-MPW was the key predictor for H-UPPP surgical success, whereas mandibular plane angle (MPA) and Friedman stage were the key predictors for ZPPP surgical success. In conclusion, U-MPW was a significant predictor of UPPP surgical success. Patients with U-MPW >10 mm who are unwilling to receive nasal continuous positive airway pressure (CPAP) therapy might be suitable candidates for UPPP surgery.
