Abstract

PURPOSE

To determine the viability of lacrimal sinus diversion by using a novel Sinopsys Surgical Lacrimal Stent.

METHODS

Two disarticulated cadaveric heads were used in the laboratory. First, bilateral conjunctivodacryocystorhinostomies (CDCR) were performed by using a traditional Pyrex Jones tube and the Sinopsys Surgical Lacrimal Stent. The fluiditics were then evaluated by using contrast agent and fluroscopy. Subsequently, conjunctivoethmoidectomies (CE) and conjunctivomaxillectomies (CM) were performed by using the Sinopsys Surgical Lacrimal Stent, of which the fluiditics were also studied.

RESULTS

The conjunctivodacryocystorhinostomy (CDCR) placement experience of the Jones tube and the Sinopsys Surgical Lacrimal Stent were similar. The CDCR fluiditics as measured by using contrast agent and fluoroscopy were identical with each draining 0.5 mL over 5 to 10 seconds. Placement of the Sinopsys Surgical Lacrimal Stent in the 4 ethmoid (CE) and 4 maxillary (CM) sinuses was similar to the CDCR experience. Fluiditics of lacrimal sinus diversion were similar to CDCR with drainage of 0.5 mL over 5 seconds.

CONCLUSIONS

The Sinopsys Surgical Lacrimal Stent has flow characteristics that are similar to a Pyrex Jones tube. Drainage in the nose via a CDCR procedure is similar to drainage in the ethmoid and maxillary sinuses via a CE and CM, respectively.

摘要

目的

通过使用新型 Sinopsys 手术泪道支架来确定泪囊引流的可行性。

方法

在实验室中使用了 2 个分离的头颅。首先，通过使用传统的 Pyrex Jones 管和 Sinopsys 手术泪道支架进行双侧结膜囊鼻腔吻合术（CDCR）。然后通过使用造影剂和荧光透视术评估流体动力学。随后，通过 Sinopsys 手术泪道支架进行结膜颌窦切除术（CE）和结膜上颌窦切除术（CM），并研究其流体动力学。

结果

Jones 管和 Sinopsys 手术泪道支架的 CDCR 放置经验相似。通过使用造影剂和荧光透视术测量的 CDCR 流体动力学相同，每种情况下均在 5 到 10 秒内引流 0.5 毫升。在 4 个筛窦（CE）和 4 个上颌窦（CM）中放置 Sinopsys 手术泪道支架的经验与 CDCR 相似。泪囊引流的流体动力学与 CDCR 相似，在 5 秒内引流 0.5 毫升。
