title: The relationship between night time snoring and cormack and lehane grading.
abstract: BACKGROUND
  airway management is one of the greatest concerns of anesthesiologists and difficult intubation, well known as the anesthesiologist's nightmare, is an event not easy to predict before induction of anesthesia. The aim of this study was to assess the relationship between history of snoring and the Cormack and Lehane grading score.
  
  
  METHODS
  in a descriptive-analytical study, 120 candidates for elective surgery were selected and allocated in the two groups (snoring and snoring free groups, respectively). The history of night time snoring was taken from the patient's wife/husband. After induction of anesthesia, each patient was assessed regarding the Cormack and Lehane grading under direct laryngoscopy.
  
  
  RESULTS
  the difference between the two groups regarding Cormack and Lehane grading system was statistically significant.
  
  
  CONCLUSIONS
  the findings of this study demonstrated a relationship between the presence of snoring and increased number of Cormack & Lehane grading score.
