PRIMARY ADULT ENDOSCOPIC DACRYOCYSTORHINOSTOMY: A NEW EXPERIENCE IN DUHOK
Background: Over the last decade dacryocystorhinostomy has been considered as the primary surgery to treat nasolacrimal duct obstruction aiming to bypass the obstructed nasolacrimal duct. Dacryocystorhinostomy has two types: traditional external and new endoscopic. The major advantages of the endoscopic technique over the open one are that there is no external incision and the subsequent scar is needed to do the surgery, very low risk of injuring the medial canthus, and the maintenance of the orbicularis oculi muscle pumping mechanism.
Study aim: This study aims to assess the success rate, surgical outcome, and complications among patients who will undergo this surgery.
Patient and Methods: this is a retrospective study conducted on (38) patients who performed endoscopic dacryocystorhinostomy at Vin private hospital in Duhok in the period between (2015–2018) where the medical records of the patients were reviewed in detail to obtain the required information for the study purposes. The information including surgery, surgery side, patients complaints, and outcome of surgery was documented.
Results: Success of the surgery is considered when there is an absence of epiphora and other symptoms 3 months postoperatively with endoscopic visualization of the newly fashioned ostium. The results showed that around (89.5%) of the patient, have complete recovery of their original symptoms, and (10.5%) are regarded as failures for whom there is no improvement of their symptoms at all.
Conclusion: Endoscopic dacryocystorhinostomy is an effective surgical procedure in treating primary acquired nasolacrimal duct obstruction with comparable outcomes to the old external dacryocystorhinostomy with fewer side effects and complications.
