PURPOSE: To evaluate the efficacy of anterior-side rectangular 4-snip punctoplasty, a modification of posterior ampullectomy that is currently used in patients with punctal stenosis. METHODS: We performed a retrospective chart review of patients with punctal stenosis who underwent anterior-side rectangular 4-snip punctoplasty at our hospital. Fluorescein dye disappearance test (FDT) and questionnaire on tearing symptoms and tear meniscus height (TMH) based on spectral-domain optical coherence tomography (SD-OCT) were evaluated in preoperative and postoperative follow-up examinations of the patients. Anatomical success was defined as punctum without re-stenosis at last visit; functional success was defined as FDT grade of 0 or 1, or tearing symptom score of 2 or less. RESULTS: A total of 44 anterior-side 4-snip punctoplasty procedures were performed in 27 patients. The average age of all subjects was 56.0 +/- 11.0 years (range, 39 to 82 years). The mean follow-up period was 9.4 months (range, 6 to 20 months). FDT, tearing symptom score (p < 0.01, Wilcoxon signed-rank test), and TMH (p < 0.01, paired t-test) were significantly decreased after surgery. Anatomical success was 40/44 cases (90.9%) and functional success was 38/44 cases (86.4%). There were no complications such as skin defect or cosmetic problems. CONCLUSIONS: Anterior-side rectangular 4-snip punctoplasty is an effective surgical procedure for patients with punctal stenosis, maintaining functions of the lacrimal drainage system without re-stenosis of punctum.
