[Efficacy of nasal cavity ventilation expansion surgery for OSAHS with multiplane obstruction].

Objective:To evaluate the improvement of nasal obstruction sympotom， AHI and LSaO²of OSAHS patients with multiplane obstruction after nasal cavity ventilation expansion techniques.Method:All the 41 OSAHS patients diagnosed by PSG were assessed with multiplane obstruction after examinations.Nasal cavity ventilation expansion techniques were performed. Each patient received the examinations of acoustic rhinometry and nasal resistance to assess the objective nasal ventilation, completed the nasal obstruction symptom evaluation(NOSE) scale to assess the subjective nasal obstructon. Postoperative datas were obtained at least 3 months later. Result:①The unilateral nasal volume 0-5 cm（UV5）were significantly changed(P<0.05), whereas the nasal resistance(NR)and NOSE were significantly decreased(P<0.05);②the AHI was significantly decreased,the LSaO2 was significantly increased(P<0.05). Conclusion:①The nasal cavity ventilation expansion techniques can improve the nasal ventilation of OSAHS patients with multiplane obstruction;②the postoperative AHI was significantly decreased whereas the chronic hypoxemia of patients was improve after surgery. Nasal cavity ventilation expansion surgery was effective and helpful for the later treatments for OSAHS patients with multiplane obstruction.
