title: [The evaluation of nasal ventilatioan in patients with obstructive sleep apnea-hypopnea syndrome after nasal cavity ventilation expansion techniques by using acoustic rhinometry].
abstract: OBJECTIVE
  To evaluate nasal ventilation in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) after nasal cavity ventilation expansion techniques by using acoustic rhinometry.
  
  
  METHODS
  Thirty-eight patients with mild OSAHS and 17 patients with moderate OSAHS who were diagnosis by PSG were selected. The acoustic rhinometry and rhinomanometry were used to assess the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) before and after the surgery (6 month later).
  
  
  RESULTS
  The state of mild OSAHS group in NCV, NMCA and NR: before surgery (2.41 ± 1.33) cm³, (0.37 ± 0.39) cm², (2.07 ± 1.48) cmH₂O/(L · min), after surgery (2.53 ± 1.54) cm³, (0.45 ± 0.34) cm², (1.69 ± 1.03) cmH₂O/(L · min), has significant difference (P < 0.05). The state of moderate OSAHS group in NCV, NMCA and NR: before surgery (2.03 ± 1.54)cm³, (0.29 ± 0.39) cm², (3.47 ± 2.56) cmH₂O/(L · min), after surgery (2.31 ± 1.47) cm³, (0.39 ± 0.33) cm², (1.89 ± 1.03)cmH₂O/(L · min), also has significant difference (P < 0.05), while DCAN in two group had no difference (P > 0.05).
  
  
  CONCLUSIONS
  There was an objective evaluation of nasal ventilation in OSAHS patients after surgery by using acoustic rhinometry.
