INTRODUCTION
Dacryocystorhinostomy (DCR) has been performed in patients with chronic stenosis of the lacrimal drainage system.
It is based on the formation of a fistula on the lateral nasal wall between the nasal cavity and the lacrimal sac.
The operation can be carried out using either an external or endonasal surgical approach.
The external approach was popularized first and became the surgery of choice for most ophthalmologists.
PATIENTS AND METHODS
Thirty-six patients (25 females and 11 males)underwent 42 endoscopic DCR operations for complaints of continuous epiphora and recurrent swelling in the medial canthal
The study was conducted at the Ophthalmology and Ear Nose Throat Clinics, Mustafa Kemal University, between 2007 and 2008
Ages ranged from 16 to 60 yrs, with a mean age of 34.79± 9.5 years
Preoperatively all patients underwent routine ophthalmologic and
otorhinolaryngologic examination
NLD obstructions were confirmed by the results of lacrimal irrigation and dacryocystographies
SURGICAL TECHNIQUE
Then the bony structure was elevated using a chisel and hammer
and removed with forceps.
Identification of the sac was aided by passing a lacrimal probe through the inferior canaliculus into the sac
The lacrimal sac opening was widened using Blakesley-Wilde
forceps and through cutting punches
The patency of the lacrimal drainage system was checked with
saline irrigation
CONCLUSION
This method is effective in primary cases with lacrimal sac or nasolacrimal duct obstruction
Prolene is also a cheap material and is readily available in almost all operating theaters and it permits tear flow into the nose following surgery
It represents a good alternative to silicone, especially in settings with limited resources
