title: Modified approach to powered endoscopic dacryocystorhinostomy.
abstract: OBJECTIVE
  This paper presents modifications to powered endoscopic dacryocystorhinostomy without stenting for the management of acquired nasolacrimal duct obstruction.
  
  
  METHODS
  A retrospective, non-randomised review.
  
  
  METHODS
  A total of 105 patients with epiphora secondary to acquired nasolacrimal duct obstruction were operated on by our modified powered endoscopic dacryocystorhinostomy approach.
  
  
  RESULTS
  Of 105 patients, 100 (95.2 per cent) have remained asymptomatic. One patient with a narrow ostium had improved symptoms, while four patients continued to experience persistent symptoms (treatment failures).
  
  
  CONCLUSIONS
  The modified powered endoscopic dacryocystorhinostomy approach led to excellent results, without bone exposure and granulations, and with early mucosalisation.
