Transconjunctival cryosurgical extraction (TCE) is not an accepted method for the removal of most intraorbital tumors, and thus is not routinely performed. This study evaluates TCE for orbital cavernous hemangioma (OCH), which, due to its specific vascular structure, is suitable for this technique.
In this retrospective case series, the medical charts of 12 consecutive patients with OCH who underwent TCE were reviewed. The operative complications and the surgical outcome were analyzed.
Eleven tumors were intraconal and 1 was extraconal. No tumor involved the orbital apex. In 10 patients (83%), the operation was uneventful. One patient lost vision due to intraoperative cilioretinal arterial occlusion. In another patient, the tumor could not be identified and was subsequently removed via lateral orbitotomy.
TCE, a relatively minor operation, is as safe as more extensive surgical procedures for the removal of OCH not located in the posterior third of the orbital space.
经结膜冷冻手术摘除术（TCE）并非大多数眶内肿瘤公认的摘除方法，因此未常规开展。本研究评估TCE用于眼眶海绵状血管瘤（OCH）的情况，因其特殊的血管结构，该技术适用于此。
在这个回顾性病例系列中，回顾了连续12例行TCE的OCH患者的病历。分析手术并发症及手术结果。
11个肿瘤位于肌锥内，1个位于肌锥外。无肿瘤累及眶尖。10例患者（83%）手术顺利。1例患者因术中睫状视网膜动脉阻塞而失明。另一例患者未找到肿瘤，随后经外侧眶切开术将其摘除。
TCE是一种相对较小的手术，对于摘除不在眶后三分之一部位的OCH，其安全性与更广泛的手术方法相当。
