To determine risk factors for early failure of the bilamellar tarsal rotation procedure in trachomatous trichiasis.
This was a prospective study in which the bilamellar tarsal rotation procedure was performed on 638 eyelids in Menofiya governorate in Egypt over a 4-year period. An analysis was performed to determine the incidence of early surgical failure (defined as one or more lashes touching the eyeball) after 8 weeks and to determine the risk factors for these failures.
Follow-up data were available on 599 eyes at 8 to 10 weeks after surgery. Considering all eyes, failure (one or more lashes touching the eyeball) was noted in 98 eyes (16.4%). Failure was associated with preoperative corneal staining (RR, 3.27; 95% CI, 2.34 to 4.57), preoperative corneal opacity (RR, 1.64; 95% CI, 1.15 to 2.34), the use of silk sutures (RR, 54.82; 95% CI, 7.72 to 389.4), and the use of 4 or more sutures (RR, 1.24; 95% CI, 1.04 to 1.48).
The finding that specific sutures or needles was associated with early failure of the bilamellar tarsal plate rotation procedure for trachomatous trichiasis was unexpected and deserves further study.
确定沙眼性倒睫双层睑板旋转术早期失败的危险因素。
这是一项前瞻性研究，在4年时间里对埃及米努夫省的638只眼睑进行了双层睑板旋转术。进行分析以确定8周后早期手术失败（定义为一根或多根睫毛接触眼球）的发生率，并确定这些失败的危险因素。
术后8至10周有599只眼的随访数据。在所有眼中，98只眼（16.4%）出现失败（一根或多根睫毛接触眼球）。失败与术前角膜染色（相对危险度，3.27；95%可信区间，2.34至4.57）、术前角膜混浊（相对危险度，1.64；95%可信区间，1.15至2.34）、使用丝线缝合（相对危险度，54.82；95%可信区间，7.72至389.4）以及使用4根或更多缝线（相对危险度，1.24；95%可信区间，1.04至1.48）有关。
特定缝线或缝针与沙眼性倒睫双层睑板旋转术早期失败相关这一发现出乎意料，值得进一步研究。
