Inferior Flap Anastomosis in External Dacryocystorhinostomy

Abstract

The inferior flap design simplifies the surgical procedure and produces success rates comparable with those found in conventional DCR. Further studies with larger numbers of patients are necessary.

Anastomosis of Both Posterior and Anterior Flaps or Only Anterior Flaps in External Dacryocystorhinostomy

“…8 Therefore, suturing the posterior flaps may be relatively difficult and limiting stage for surgeons who are not well-experienced, due to limited area especially in the presence of hemorrhage. 11,12 Thus, several alternative techniques in flap design have been currently suggested with similar degrees of success rates. [8][9][10][11][12] Baldeschi et al 8 compared 3 different patterns of mucosal flap design (anterior and posterior, extended anterior with posterior and only anterior) in external DCR.…”

“…11,12 Thus, several alternative techniques in flap design have been currently suggested with similar degrees of success rates. [8][9][10][11][12] Baldeschi et al 8 compared 3 different patterns of mucosal flap design (anterior and posterior, extended anterior with posterior and only anterior) in external DCR. They found that the success rates among 3 groups differing in flap design were similar.…”

“…11 However, performing both anterior and posterior flap anastomosis may take a long operative time in conventional DCR. 11,12 Approximating the nasal and lacrimal mucosal flaps may be difficult in patients where the lacrimal bone or the maxillary frontal process is pneumatized by anterior ethmoidal cells, because of causing a significant space between the lacrimal sac and the nasal mucosa. 8 Therefore, suturing the posterior flaps may be relatively difficult and limiting stage for surgeons who are not well-experienced, due to limited area especially in the presence of hemorrhage.…”

“…However, there are few studies comparing the outcomes of DCR performed with different mucosal flap procedures. [8][9][10][11][12] Therefore, in this study, we evaluated the outcomes of external DCR by using two different patterns of flap anastomosis; one only with anterior flap anastomosis and the other with both anterior and posterior flap anastomosis.…”

Surgical Success in Single Flap External Dacryocystorhinostomy

“…Arka flep oluşturulması ve sütürasyonu aşaması derin ve dar bir alanda çalışmayı gerektirdiğinden, bu durum cerrahi süresinin uzamasına; kanama ve flep zedelenmesi gibi komplikasyonlara neden olabilmektedir. 16,17 Bu aşamayı kısaltmak ve kolaylaştırmak için bir çok teknik değişiklik yapılagel-miştir. Literatürde arka flebin eksizyonu ve sütüre edilmemesi, değişik şekilli mukozal fleplerin oluştu-rulmasına ait raporlar bulunmaktadır.…”
