title: [Efficacy of endoscopic nasal lateral wall dissection approach in the treatment of maxillary sinus diseases].
abstract: OBJECTIVE
  A retrospective analysis of the clinical efficacy on the surgery of maxillary sinus diseases via the endoscopic lateral nasal wall incision, and a discussion on the clinical application of this approach.
  
  
  METHODS
  Eighteen cases of the maxillary sinus diseases diagnosed on the basis of the preoperative nasal endoscopy, CT scan or MRI, and pathologic finding. Among 13 patients underwent routine lateral nasal wall incision approach, including 4 of maxillary sinus hemorrhagic and necrotic polyps, 4 of maxillary sinus cyst, and 3 of the maxillary sinus fungal infection. Five patients underwent lateral nasal wall resection approach and thorough maxillary sinus lesions resection by nasal endoscope, including 3 of inverted maxillary sinus papilloma, a nasal sinus bone giant cell tumor and a spindle cell tumor. Patients were followed up for more than half a year, and the postoperative efficacy were observed.
  
  
  RESULTS
  The surgical cavity of the lateral nasal wall incision approach have luminal epithelium, well shapes of inferior turbinate, no recurrence of the lesion, and the lateral nasal wall resection patients with well luminal epithelium, without recurrence. All patients had no complications such as numbness, tears, etc.
  
  
  CONCLUSIONS
  Endoscopic incision of lateral nasal wall keep the nasolacrimal duct and inferior turbinate, help remove the entire sinus cavity lesion and retain the physiological function of the nasal cavity. Resection of the lateral nasal wall can reveal an ideal vision approach, which perform certain clinical value for the treatment of the inverted maxillary sinus papilloma and sinus cancer.
