Amaç: Nazolakrimal kanal (NLK) tıkanıklığı olan hastalarda uyguladığımız transkanaliküler diod lazer dakriyosistorinostomi (TDL-DSR) sonuçlarını değerlendirmek. Materyal ve Metot: Geriye dönük çalışmaya 32 hastanın (25 kadın, 7 erkek) 36 gözü alındı. Çalışmaya epifora şikayetiyle başvurup, lakrimal lavaj sonrasında NLK pasajı tıkalı olan ve burun içi patolojisi olmayan olgular dahil edildi. Cerrahi sonrası lavajın açık olması ve epiforanın kaybolması cerrahi başarı olarak değerlendirildi. Olguların ortalama takip süresi 23,9±10,2 ay (7- 39 ay aralığında) idi. Bulgular: Olguların yaşları ortalaması 40,2±14,3 yıl (9- 74 yıl aralığında) idi. Otuz altı olguya TDL-DSR uygulandı. Olgulardan 26’sına (%72,2) silikon tüp entübasyonu uygulanırken, 10 olguya (%27,8) silikon tüp entübasyonu uygulanmadı. Ortalama cerrahi süresi 28,25±5,58 dk (18-38 dakika aralığında) idi. Silikon uygulanan grupta cerrahi süre ortalama 30,73±4,23 dk, silikon tüp uygulanmayan grupta 21,80±2,25 dk bulundu (p

Background: To evaluate the results of transcanalicular diode laser dacryocystorhinostomy (TDL-DCR) surgery in patients with nasolacrimal canallicular (NLC) obstruction. Material and Methods: Retrospectively, thirty six eyes of 32 patients (25 female, 7 male) were reviewed in the study. Patients who applied with complaint of epiphora underwent nasolacrimal lavage. The patients with NLC obstruction and free from intranasal pathologies were enrolled in this study. Surgical success was defined as patency of lavage and loss of epiphora in the post- operative period. The mean follow-up time was 23.9±10.2 months (range: 7- 39 months). Results: The mean age of patients was 40.2±14.3 years (range: 9-74 years). TDL-DCR was performed in thirty- six cases. The silicon tube was intubated in 26 (72.2%) of the cases. Overall, the mean surgery time was 28.25±5.58 minutes (range: 18-38 minutes). The mean surgery time was 30.73±4.23 minutes in the group with silicon tube intubation and 21.80±2.25 minutes in the group without silicon tube (p <0.01). The success rate of the TDL-DCR was found to be 52.77%. There was no difference between the success rate of groups with or without silicon tube intubation (p=0.46). Conclusions: TDL-DCR is an effective and successful method for the treatment of NLC obstruction. We think that surgical success can be improved with effective use of endoscope and adjuvant therapy.
