title: Recurrence rates after endoscopic sinus surgery for massive sinus polyposis.
abstract: OBJECTIVE
  Most studies on outcome after endoscopic sinus surgery (ESS) include patients with varying degrees of disease severity. Recurrence rates cited by those studies may not apply to the subset of patients with severe polyposis. Our aim is to provide reference information for recurrence rates and need for revision surgery in patients with severe disease.
  
  
  METHODS
  Review of patients with severe polyposis with a minimum Lund-McKay score of 16 and with a Kennedy computed tomography stage 3 or 4. Data collection included demographics, presence of asthma or documented allergy, history of previous surgery, extent of surgery, preoperative and postoperative management, recurrence rates, revision surgery rates, and follow-up.
  
  
  RESULTS
  One hundred and eighteen records were reviewed. Fifty-nine (50%) patients had asthma, and 93 (79%) had documented allergy. All patients required extensive bilateral nasal polypectomy, complete anterior and posterior ethmoidectomy, and maxillary sinusotomy. One hundred (85%) also had frontal or sphenoid sinusotomy. Follow-up ranged from 12 to 168 (median 40) months. Seventy-one (60%) developed recurrent polyposis. Fifty-five (47%) were advised to undergo revision surgery, and 32 (27%) underwent surgery. History of previous sinus surgery or asthma predicted higher recurrence (P <.005, P <.001) and revision surgery rates (P =.02, P <.001). History of allergy also predicted recurrence and need for revision (P <.001, P <.001).
  
  
  CONCLUSIONS
  Recurrence rates after ESS for severe polyposis are significant. In our study, patients with asthma are at higher risk of recurrence.
