INTRODUCTION: This study aims to compare the retrospective results of patients on whom silicone intubation was performed using either the monocanalicular or bicanalicular method and for whom probing and lavage procedures had failed for the treatment of congenital nasolacrimal duct obstruction (CLDO).
METHODS: A total of 47 eyes of 42 patients – 25 females; 17 males – on whom silicone tube intubation was performed due to congenital nasolacrimal duct obstruction (CLDO) were involved in the study. As part of the study, a monocanalicular tube was placed in 23 of the 47 eyes (1st group), while a bicanalicular tube was placed in 24 of the eyes (2nd group). The average age in the first group was 6.13 years (1–15 years) and 4.51 years (1–15 years) in the second group. Extubation was performed in the postoperative 4.2 month (2–7 months) in the first group and in the postoperative 4.4 month (2–7 months) in the second group. Average length of follow-up of cases was determined to be 10.1 months (6–72 months).

RESULTS: The procedure had a success rate of 82% (19 of 23 eyes) in the first group, while the success rate of the procedure conducted in the second group was 79% (19 of 24 eyes), with the difference between the groups determined not to be statistically significant (p=0.76)(Kikare Test). Premature removal of tube was seen in three cases in the first group, with two patients having to be re-intubated and the other not having to be due to the absence of any more complaints. Tube prolapsus from the medial canthal region was seen in two patients from the second group in the second week after operation, resulting in them being extubated in the early period. Pyogenic granuloma was seen in one case in the first group and conjunctivitis in another case in the same group. However, no conjunctival or corneal complications were determined in either patients.

DISCUSSION AND CONCLUSION: The success rate of monocanalicular and bicanalicular silicone tube intubation in patients who had undergone an ineffective probing procedure was determined to be similar, and there was no difference found between the two procedures in terms of their complication rates.

GÝRÝÞ ve AMAÇ: Doðumsal nazolakrimal kanal týkanýklýðýnda (DNLKT) sondalama ve lavaj iþleminin basarýsýz olduðu ve monokanaliküler veya bikanaliküler yöntem ile silikon entübasyon uygulanmýþ olgularýn geriye dönük sonuçlarýný karþýlaþtýrmak.
YÖNTEM ve GEREÇLER: Doðumsal nazolakrimal kanal týkanýklýðý (DNLKT) nedeniyle silikon tüp entübasyonu yapýlan 25'i kýz,17'si erkek 42 olgunun 47 gözü çalýþmaya alýndý. Çalýþmada 47 gözün 23'üne (1.grup) monokanaliküler tüp, 24'üne (2.grup) ise bikanaliküler tüp yerleþtirildi. Birinci grupta yaþ ortalamasý 6,13 yýl (1 -15 yaþ), ikinci grupta yaþ ortalamasý 4,51 yýl (1- 15 yaþ) idi. Tüp çýkarýmý birinci grupta ameliyat sonrasý 4,2 ay (2-7 ay), ikinci grupta ortalama 4,4 ayda (2-7 ay) yapýldý.Olgularýn ortalama takip süresi 10,1 ay (6-72 ay) olarak saptandý.
BULGULAR: Birinci gruptaki 23 gözün 19 unda (% 82), 2. gruptaki 24 gözün 19 unda (% 79) baþarý tespit edildi. Gruplar arasýndaki fark istatistiksel olarak anlamlý bulunmadý (p=0.76)(Ki Kare Testi). Birinci grupta 3 olguda tüpün yerinden erken çýktýðý görüldü. Bu olgularýn ikisine yeniden tüp yerleþtirildi fakat diðer olgunun þikayetleri geçtiðinden tekrar tüp yerleþtirilmedi. Ýkinci grupta 2 olguda ameliyat sonrasý 2. haftada medial kantal bölgeden tüp prolapsusu görüldü ve erken dönemde tüpleri çýkartýldý.
TARTIÞMA ve SONUÇ: Sondalama iþlemi baþarýsýz olan olgularda monokanaliküler ve bikanaliküler silikon tüp entübasyonu baþarý oranlarý birbirine benzerdir ve komplikasyon oranlarý arasýnda fark yoktur.

Anahtar Kelimeler: Bikanaliküler entübasyon, doðumsal, monokanaliküler entübasyon, nazolakrimal kanal týkanýklýðý.
