Open book technique for conjunctival tumors: a surgical approach to the fornix

ABSTRACT Surgical management of large tumors involving the conjunctival fornix can be challenging, as exposure and clear margins may be difficult to achieve. In this case series, we report our initial experience with the open book technique in 4 patients. Through a canthotomy and cantholysis, this surgical approach provides a wide surgical field and facilitates fornix reconstruction post large tumor excision. In our series, one patient had a lateral canthus dehiscence.

【摘要】 累及结膜穹窿（conjunctival fornix）的大型肿瘤的外科治疗颇具挑战性，因手术暴露与清晰切缘的获取往往存在难度。本病例系列报告了4例患者应用开卷术式（open book technique）的初步临床经验。通过外眦切开术（canthotomy）与外眦松解术（cantholysis），该外科术式可获得开阔的手术视野，并便于大型肿瘤切除后结膜穹窿的重建。本系列中，1例患者出现了外眦裂开并发症。
