Outcome of external dacryocystorhinostomy combined with membranectomy of a distal canalicular obstruction.

PURPOSE: To investigate the accuracy of the preoperative evaluation in identifying a membranous obstruction of the distal canaliculus and the success rate of an external dacryocystorhinostomy (DCR) when membranectomy of the canalicular obstruction is also performed. DESIGN: Retrospective, interventional case series. METHODS: The surgical records of the lacrimal cases operated at Moorfields Eye Hospital between January 1997 and December 1999 were reviewed. All the patients with evidence of a membranous block of the canalicular opening into the sac identified and excised during the course of a standard DCR procedure with silastic intubation and a minimum follow-up period of 12 months were selected for this study. The records were analyzed for preoperative evaluation with syringing and probing, surgical details, outcome, and complications. RESULTS: In 59 (85%) cases a functional anastomosis was established after tube removal. Additionally, 5 cases (7%) had patent system but required later ectropion repair and considered successful. Only 4 (6%) patients needed further lacrimal surgery, and one was referred to the ENT department for nasal polyps. The silastic tube was removed at a mean period of 6 weeks (SD = 4; range, 2-24 weeks), and the mean follow-up period was 13 months (SD = 3; range, 12-29 months). The preoperative evaluation failed to identify the membranous obstruction in 30 (43%) cases, which were correctly diagnosed intraoperatively. CONCLUSIONS: In our series the anatomic success rate of 92% after DCR with membranectomy is comparable to the outcome of the DCR procedure. The distal canalicular membranous obstruction is an anatomic factor that may lead to surgical failure if not identified and excised.

Endoscopic placement of Jones lacrimal tubes with the assistance of holmium YAG laser.

INTRODUCTION: The aim of this paper is to highlight the use of the Holmium YAG laser in the endoscopic placement of Lester Jones tubes in patients with a blocked canaliculus or failed lacrimal pump function. MATERIALS AND METHODS: Sixteen cases with a non-functional canaliculus were included over a one-year period. Following caruncle excision, a 19 G needle is inserted through the medial canthal tissues into the nasal space. Nasal endoscopy confirms the accurate positioning in relation to the nasal anatomy. With the Holmium YAG laser, a tissue channel is fashioned around the guide needle through the structures of the lateral nasal wall to facilitate an accurate and secure placement of the Jones tube. RESULTS: The endoscopic, laser-assisted placement reduces the operating time to less than 20 minutes, minimizes tissue trauma and does not require the initial surgical steps of an open DCR procedure. There were 14 cases (87.5%) with securely retained tubes and two cases (12.5%) that required tube replacement. The advantage of the procedure is especially great in revision surgery where the ostium is opened through scar tissue. CONCLUSIONS: Nasal endoscopy with the assistance of the Holmium YAG laser offers simplicity and precision in the placement of Jones tubes. It minimizes tissue trauma and increases the surgical success rate.

Combination of periocular myocutaneous flaps for one-stage reconstruction of extensive defects of the eyelid.

We present the reconstructive challenge after excision of a large periocular tumour in a patient who needed early visual rehabilitation. The periocular full thickness deficit of his only sighted eye was reconstructed with a combination of periocular myocutaneous flaps and a free buccal mucosal graft. Adequate functional and cosmetic results with early visual rehabilitation were achieved in a single procedure.
