title: [Risk factors for postoperative pulmonary complications following transoral operation for the atlanta-axis disorders].
abstract: OBJECTIVE
  to evaluate the risk factors for postoperative pulmonary complications following transoral operation for the atlanta-axis disorders.
  
  
  METHODS
  total 104 cases were collected from January 2005 to June 2009. Twelve variables among patients with PPCs and without PPCs were analyzed by logistic regression analysis.
  
  
  RESULTS
  the incidence of postoperative pulmonary complications following transoral operation for the atlanta-axis disorders was 22.1% (23/104). There was significantly difference in 9 variables between patients with PPCs and without PPCs, and 5 variables as serum albumin < 35 g/L (OR = 15.185, P = 0.003), tracheotomy (OR = 32.254, P = 0.015), Frankle grade (OR = 8.866, P = 0.001), the duration of intubation > 4 d (OR = 7.934, P = 0.002), the duration of surgery > 6 h (OR = 16.889, P = 0.006) were found to be significantly related to the development to postoperative pulmonary complications by multivariate analysis.
  
  
  CONCLUSIONS
  serum albumin < 35 g/L, tracheotomy, Frankle grade, the duration of intubation > 4 d, the duration of surgery > 6 h are the risk factors for postoperative pulmonary complications following transoral operation for the atlanta-axis disorders.
