Abstract:
OBJECTIVE:In order to improve the postoperative effect of modified UPPP, removing the partial pharyngeal muscle in surgery, we investigate the postoperative effect, the characteristics of pharyngeal cavity and the potential complications in OSAHS patients.
METHOD:To choose 82 OSAHS patients with obstructive oropharyngeal plane diagnosed by Apneagraphy (AG), Fibre nasopharyngoscope combined with Müller examination and nasopharyngeal 3D-CT, which had completed clinical data inpatients in the anesthesia underwent of the partial pharyngeal muscles in the postoperative, divided into a control group of 26 cases, operating the H-UPPP surgery which did not remove partial pharyngeal muscle; The experimental group of 56 cases did a H-UPPP surgical which removed partial pharyngeal muscle of possible concurrent symptoms such as nasal regurgitation, Eustachian tube dysfunction and other follow-up study in six months after the monthly telephone follow-up or outpatient exams to understand the disease. Patients were evaluated the sleepiness by ESS(Epworth sleepiness scale) in 6 months after the surgery, compared with the preoperative ESS scores, do a t test for statistical analysis. AG can be used to evaluate effects of the UPPP after 6 months. By measuring uvula length (L1), extent from free edge of soft palate to postpharyngeal (L2) and stenosis of nasopharynx width (L3) mean, we investigate the characteristics of pharyngeal cavity using the multiple linear regression to do the hypothesis test and evaluate the association between measuring mean and effect. Using SPSS19.0 software do the preoperative contrast analysis.
RESULT:After 6 months in surgery, 56 cases in the experimental group, effect in 50 cases (89.29%), effective in 6 cases (10.71%); ESS score: Preoperative 11.74 +/- 2.48, after the first 6 months 3.84 +/- 2.05. Twenty-six cases in control group,effect in 19 cases (73.08%), effective in 7 cases (26.92%); ESS score: Preoperative 11.91 +/- 2.40, after the first 6 months 6.92 +/- 2.47, t-test P value of less than 0.05 between the experimental group and the control group; There are no ear fullness, hearing loss, increase their own sound which reflect eustachian tube dysfunction and other complications in two groups; The function of pharyngeal cavity could be recovered normal lever after 6 months; After 6 months of the operation, in the experimental group and the control group L1 mean was respectively (5.91 +/- 3.38) mm and (6.20 +/- 3.76) mm (P>0.05); L2 mean was respectively (15.70 +/- 3.29)mm and (15.35 +/- 1.44) mm (P> 0.05); L3 mean was respectively (20.54 +/- 3.33) mm and (16.43 +/- 2.21) mm (P<0.05). Nasal fauces pitch mean was significantly widened. By the multiple linear regression analysis, the postoperative effect has the linear correlation between L2 and 1,3 residual mean with the negative correlation. Due to the standardized coefficient, L3 residual mean has the most influence on the postoperative effect.
CONCLUSION:Modified UPPP surgery removing the partial pharyngeal muscle is in favor of upgrading the postoperative effect with significantly increasing the width of postoperative nasal pharyngeal isthmus area, then there are not occur the eustachian tube dysfunction, the soft palate function, swallowing and articulation function disabled.
