title: [Application of endoscopic nasal lateral wall dissection in lesions of the maxillary sinus].
abstract: OBJECTIVE
  To investigate the application of endoscopic nasal lateral wall dissection in lesions of the maxillary sinus.
  
  
  METHODS
  Ten hospitalized patients with the maxillary sinus lesions were treated with the endoscopic nasal lateral wall dissection.
  
  
  RESULTS
  All 10 patients were unilateral invasion. Among them, 7 cases were inverted papilloma, 2 cases were recurrent antrochoanal polyps, 1 case was sinusal tooth. The tumors and antrochoanal polyps originated from the every part of the maxillary sinus wall during operation, especially from the anterior and media wall. During 10-62 months follow-up,epithelization of nasal occured and the shape of inferior turbinate was well. All of them had no epiphora.
  
  
  CONCLUSIONS
  Endoscopic nasal lateral wall dissection can remain the function of nasal lacrimal duct and nasal cavity,and may provide a new minimally invasive approach for complete resection of lesions of nasal cavity and the maxillary sinus.
