Selective non‐intubation of a silicone tube in external dacryocystorhinostomy

Abstract

ABSTRACT.Purpose: To evaluate whether silicone tube insertion is always necessary in external dacryocystorhinostomy (DCR). Methods: During external DCR for primary nasolacrimal duct obstruction carried out between January 2001 and October 2004, silicone intubation was not performed selectively if the lacrimal sac was large and the nasal cavity was not severely narrowed. Results: Of a total of 166 DCR cases in 153 patients, no silicone tube was placed in 74 eyes of 69 patients (44.6%). Anatomic patency of rhinostomy was achieved in all non-intubation group eyes. However, four (6.7%) of these 69 eyes showed persistent epiphora even with anatomic patency. Conclusions: Silicone tubing can be avoided in about 50% of cases of external DCR without detrimentally affecting the success rate. Cases in which intubation was avoided had a large lacrimal sac and a wide nasal cavity.

Outcome of External Dacryocystorhinostomy with Bicanalicular Silicone Tube Stenting

“…The purpose of the stent in the nasolacrimal system is to prevent adhesion of the mucosal lining of the channels during the healing process and to maintain longterm patency after removal. Despite these advantages of silicone stents, complications, such as peripunctal granulation, erosions of puncta and canaliculi, chronic nasal irritation, corneal erosion, canalicular laceration, interpunctal symplepharon, inflammatory mass, and pyogenic granuloma formation, have been reported (10). In addition to these complications, some articles indicating that silicone stents induce formation of granulation tissue on the anastomotic site, decreasing the success rate of DCR operations, have been published.…”

Effectiveness of canalicular laceration repair using monocanalicular intubation with Monoka tubes

“…These tubes have also been reported to give rise to several complications, including canalicular slitting, granuloma formation, superior loop dislocation, infection and corneal abrasion (Veloudios et al 1988;Choung & Khwarg 2007).…”

Bikanaliküler Entübasyon ve Cilt Sütürasyonu ile Kanaliküler Kesi Onarım Sonuçları

“…Buna karşılık, cerrahi tecrübe ile endoskop ihtiyacı anlamlı oranda azalmakta ve ameliyat süresi kısalmaktadır. Ayrıca, bikanaliküler nazal entübasyonda özel cerrahi gereçlere ihtiyaç duyulması, postoperatif dönemde punktum erozyonu ve granülom oluşumu gibi komplikasyonlara yol açması bakımından dezavantajlara sahiptir [23]. Kanalikül travmalarında silikon tüpün kalış süresi ile ilgili ortak bir görüş olmamakla birlikte tavsiye edilen süre 3-12 ay arasında değişmektedir [24,25].…”

“…Bu sebeple göz kapağı travmalarında mutlaka kanaliküler sistem açıklığı ve bütünlüğü muayene edilmelidir [1][2][3][4]. Yaralanmadan yaklaşık [16][17][18][19][20][21][22][23][24] saat sonra kanalikül ve çevreleyen dokularda ödem geliştiği ve bu durumun yaralanma tespitini güçleştirdiği bildirilmiştir [3]. Bu sebepten, cerrahi müdahale mümkün olan en kısa sürede planlanmalıdır [4].…”
