title: [Evolution of maxillary sinus surgery in a university hospital].
abstract: BACKGROUND
  Maxillary sinus surgery has been evolving and, due to advances in technology, endoscopic surgery is widely used in the maxillary sinus for multiple pathologies that 15 years ago were treated through open approaches. For this reason, we conducted an observational descriptive study.
  
  
  METHODS
  We reviewed the clinical records of patients with pathology involving the maxillary sinus and who were surgically treated from January 2008 to December 2009, type of disease, surgical approach used, presence of complications, pre- and postoperative score according to the Lund-Mackay scale, and resolution (or not) of symptoms. We compared these results with a previous study carried out in 1994 in our hospital. We found a total of 177 patients with maxillary sinus-related pathology, of whom 46 patients were excluded.
  
  
  RESULTS
  In 131 patients we found a clear predominance of chronic rhinosinusitis without polyps as a pre-surgical diagnosis. We used four different approaches: endoscopic (88.5%), combined approach (5.5%), sublabial expanded (4.5%) and Caldwell Luc (1.5%); 41% of the patients received 0 points on the postoperative Lund-Mackay scale.
  
  
  CONCLUSIONS
  Surgery of the maxillary sinus in our hospital has evolved considerably; the endoscopic approach was used as a surgical treatment in >90% of patients with a low percentage of complications.
