title: Epidemiological analysis of structural alterations of the nasal cavity associated with obstructive sleep apnea syndrome (OSA).
abstract: OBJECTIVE
  The objective of this paper is to demonstrate that structural alterations of the nasal cavity, e.g. septal deviation and conchal hypertrophy have high incidence in patients with sleep apnea and hypopnea syndrome and must be addressed with associated specific procedures of the syndrome.
  
  
  METHODS
  Clinical retrospective.
  
  
  METHODS
  A retrospective study of 200 patients was performed, with 196 male and 4 female, attended at the otorhinolaryngology ambulatory of Hospital Prof. Edmundo Vasconcelos and Unidade Paulista de Otorrinolaringologia, all of them subjected to polysomnography, otorhinolaryngological physical exam, endoscopy exam, and surgical treatment with nasal and pharyngeal procedures.
  
  
  RESULTS
  All of them were subjected to pharyngeal procedure: uvulopalatopharyngoplasty or uvulopalatoplasty and nose procedure: 176 septoplasty with partial turbinectomy (88%) and 24 isolated turbinectomy, with satisfactory results.
  
  
  CONCLUSIONS
  We can see that structural alterations of the nasal cavity have high incidence in patients with OSA.
