Purpose
To evaluate the efficacy of lateral canthoplasty as a primary surgical method for treating lower eyelid entropion with a focus on lateral canthal block excision in patients at the Ophthalmology Department of the University Medical Centre Maribor Slovenia.
Methods
A retrospective analysis was conducted on the surgical treatment data for lower eyelid entropion with lateral canthoplasty from October 2017 to December 2023. The success rate was assessed based on anatomical correction, recurrence rates, and time to recurrence, with a minimum follow-up period of 6 months post-surgery.
Results
The study analyzed 112 patients (52 males, 60 females) who underwent lateral canthoplasty for lower eyelid entropion, excluding those with recurrent and cicatricial entropion. The procedures included lateral canthal block excision (LCBE, 18.8%), LCBE with everting sutures (75.9%), and lateral tarsal strip (LTS, 5.4%). The overall recurrence rate was 10.7%, with a 14.1% recurrence rate for LCBE with everting sutures and no recurrences for the other methods. The average time to first recurrence was 10 months (range: 3-30 months). Postoperative complications included wound dehiscence, granuloma, and trichiasis. In 2 patients, a surgical revision at 3 months revealed insufficient anatomical correction, while other cases showed satisfactory results. Secondary recurrence was observed in 3 patients, who were primarily treated with a combined procedure involving horizontal lid shortening, subciliary incision, and reinsertion of the lower retractors.
Conclusion
Lateral canthoplasty, which involves fixing the lateral canthus to the lateral orbital rim after lateral cantholysis, is effective for correcting horizontal laxity and malposition of the lower eyelid. At our institution, LCBE with everting sutures is the predominant method. While the observed recurrence rate is notable, it is comparable to the variable rates reported in the literature. LCBE is not only quick and easy to teach and perform, but also serves as an effective primary procedure for entropion correction.
