title: A retrospective analysis of the relationship between rhinosinusitis and sinus lift dental implantation.
abstract: BACKGROUND
  Dental implants have been associated with the occurrence of postoperative rhinosinusitis. In some patients, preoperative sinus lifting must be performed to increase the chances of successful implant placement. This retrospective study examines the relationship of dental implants after sinus lifting with the occurrence of postoperative rhinosinusitis.
  
  
  METHODS
  A total of 268 dental implants were inserted in 94 patients (62 Males, 32 Females) between 2011-2013. The ages ranged from 29-71 (in males) and 33-64 (in females). Additionally, bilateral sinus lifing was performed in 51 patients, and unilateral sinus lifting was performed in 43 of the patients. Patients were evaluated for sinus pathology for a period of 5-47 months postoperatively using a satisfaction questionnaire, conventional radiographic examination, and nasal endoscopic examination.
  
  
  RESULTS
  Four of the patients (4.2%) had a complication of postoperative sinusitis and were treated medically. In one patient, the implant was unsuccessful (even after treatment) and was removed. None of the patients needed surgery due to the sinusitis or any associated complications.
  
  
  CONCLUSIONS
  The risk for postoperative rhinosinusitis was found to be higher in patients who suffer from chronic sinusitis and in cases in which a large amount of graft was utilized for sinus lifting. These predisposing factors need to be considered when evaluating patients for dental implants and sinus lift procedures.
