Piezosurgery in External Dacryocystorhinostomy.

Published

Journal Article

BACKGROUND: Dacryocystorhinostomy (DCR) can be performed via an external or endoscopic approach. The use of ultrasonic or piezosurgery has been well described for endoscopic DCRs but is lacking for external DCRs. This study presents a case series of external DCRs performed using piezosurgery evaluating results and complications. METHODS: Prospective, consecutive case series of patients undergoing primary external DCR for lacrimal drainage insufficiency. A standard external DCR technique was used using 1 of 2 piezosurgery systems for all bone incision. All patients received silicone intubation to the lacrimal system. Surgical outcome was measured in terms of patient-reported epiphora as follows: 1) complete resolution, 2) improvement >50%, 3) improvement <50%, and 4) No improvement. Intra and postoperative complications were also recorded. RESULTS: Fifty-two patients, 14 male and 38 female, were included in the study, with 2 patients having bilateral surgery. The average age of the patients was 55.8 years. The average length of follow up was 221 days. Surgical outcomes showed 72% of patients with complete resolution of epiphora and 21% with >50% improvement. There were 4 patients (7%) who had <50% improvement. There was 1 (2%) intraoperative complication and 2 (4%) postoperative complications recorded. CONCLUSIONS: Piezourgery is a viable modality for performing external DCRs. The lack of surgical complications shows a potential for decreased soft tissues damage. The surgical success rate based on patient-reported epiphora is similar to those published for mechanical external DCRs. This modality may benefit the novice surgeon in the reduction of soft and mucosal tissue damage.
