title: Minimally invasive transnasal medial maxillectomy for treatment of maxillary sinus and orbital pathologies.
abstract: CONCLUSIONS
  Minimally invasive transnasal medial maxillectomy with preservation of the nasolacrimal duct may provide an alternative method for surgical treatment of selected maxillary sinus and inferior orbit pathology if more extensive endonasal or external approach procedures are to be avoided.
  
  
  OBJECTIVE
  To present a modification of the transnasal endoscopic approach to the maxillary sinus leading through its medial wall, anteriorly to the nasolacrimal duct that considerably improves access to the antero-inferior part of the maxillary sinus and entire orbital floor. To discuss indications for the procedure along with surgical outcome after at least 12 months of follow-up.
  
  
  METHODS
  A total of 22 selected patients with extensive/refractory inflammatory maxillary sinus disease that could not be cleared completely through middle meatal antrostomy or pathologies of the inferior orbit that required uncompromised access to the orbital floor were operated with this method. The effectiveness of the treatment was evaluated through clinical symptomatology and endoscopic examination to confirm eradication of the disease.
  
  
  RESULTS
  The presented method allowed for good overall symptom control and eradication of disease confirmed endoscopically in about 90% of cases with an inflammatory type of disease. The visualized reach within the maxillary sinus with commercially available endoscopic instruments was conspicuously improved as compared with middle meatal antrostomy.
