[Clinical analysis of individualized nasal cavity ventilation expansion techniques for treatment of OSAHS patients].

Objective: To investigate efficacy of individualized nasal cavity ventilation expansion techniques for OSAHS patients with nasal obstruction. Method: One hundred and twelve OSAHS patients with nasal obstruction were included in this study. Nasal cavity ventilation expansion techniques were performed. Every patient took the examination of acoustic rhinometry, nasal respiration volume, rhinomanometry and polysomnography, and filled VAS of nasal obstruction and Epworth Sleep Scores(ESS) before surgery and three months after surgery. Result: Follow-up was for 6－12 months. Of all the patients, 39 cases were cured, 37 cases were remarkably improved, 21 cases were effective, and 15 cases were of no effect, respectively. Compared with pre-operative examination data in all OSAHS patients, nasal ventilation was markedly improved, the ESS was significantly decreased, the AHI was significantly decreased, LSaO2 and MSaO2 were significantly increased, and sleep structure did not change significantly in all OSAHS patients 6 month after nasal surgery. Conclusion: Individualized nasal cavity ventilation expansion techniques is an effective treatment for OSAHS patients with nasal obstruction，improves the safety of patients with UPPP surgery, and the tolerability of CPAP in some patients with ineffective surgery.
