PURPOSE To compare the outcomes of external dacryocystorhinostomy (E-DCR) by using two different flap anastomosis patterns and skin incision types. METHODS This study included 79 patients (88 eyes) with lacrimal drainage system disorders who underwent E-DCR surgery. Fifty eyes of 44 patients (group A) underwent E-DCR by suturing anterior and posterior flaps (H-flap) of the lacrimal sac with c...

BACKGROUND The aim of this study was to compare the effect of W-shaped skin (WS) and linear skin (LS) incisions on cutaneous scar tissue formation in patients who have undergone bilateral external dacryocystorhinostomy. METHODS Sixteen patients (14 females and two males) with acquired bilateral nasolacrimal duct obstruction were included in this prospective, interventional comparative study. ...

BACKGROUND Nasolacrimal duct obstruction is caused by a variety of acquired and congenital etiologies. The standard treatment is dacryocystorhinostomy (DCR), with the gold standard being the external DCR. Since the advent of the nasal endoscope, the transnasal endoscopic DCR has gained popularity and has several advantages over the external approach. Some potential advantages include the avoida...

PURPOSE To investigate the clinical affects of premature silicone stent loss after external dacryocystorhinostomy (DCR). DESIGN Retrospective chart review. PARTICIPANTS Two hundred thirty-three consecutive external dacryocystorhinostomies. METHODS Demographic information was recorded, including length to follow-up, age, gender, number of days until stent removal, and success of surgery. A...

AIM To assess the dimensions and patency of the surgical epithelial fistula after external dacryocystorhinostomy, using B mode ultrasonography to define the postoperative soft tissue anastomosis. METHODS 12 patients undergoing 16 external dacryocystorhinostomies, with the creation of large osteotomies, were included in a prospective study. The horizontal and vertical dimensions of the bone os...

Data are reported on a series of 52 endoscopic procedures of dacryocystorhinostomy, performed in the Department of Otorhinolaryngology of the Hospital of Varese, between May 1999 and February 2003. The study population comprised 42 patients (32 female, 10 male. mean age 57 and 51 years, respectively) with naso-lacrimal obstruction. In all cases, pre-operative diagnosis consisted in irrigation o...

PURPOSE External and endonasal dacryocystorhinostomy (EX-DCR and EN-DCR, respectively) affect the tear drainage mechanism. This study evaluates the preservation of "lacrimal pump" function in both procedures. METHODS Cases of successful EN-DCR (4 patients) and EX-DCR (4 patients) were included. All patients underwent MRI of the rhinostomy areas, at least 6 months postoperatively. The vertical...
