To evaluate a new procedure for fixation of prolapsed nictitans glands to the cartilage of the nictitans that will not interfere with the mobility of the nictitating membrane.
A prospective clinical trial utilizing a nonabsorbable suture to anchor the prolapsed gland to the cartilage of the third eyelid was undertaken. Fifteen eyes of 10 dogs were included in the study. A 4-0 nylon suture was passed from the anterior surface of the third eyelid through the base of the cartilage to the posterior aspect and then tunneled circumferentially beneath the conjunctiva over and around the prolapsed gland. The suture was then passed through the cartilage again to the anterior face of the third eyelid. The gland was replaced into its normal position as the suture was slowly tightened and then tied on the anterior aspect of the nictitans.
Over a period of several weeks, the glands reduced in size and took on a normal appearance. All glands but one remained in place for the length of follow-up, which ranged from 2 weeks to 33 months.
This procedure results in acceptable cosmetic effects with the return of the gland to its normal position posterior to the nictitating membrane. The advantage of this technique over traditional tacking to the orbital rim is that the third eyelid retains its normal mobility and, thus, its protective functions. The procedure once mastered is very quick and can be performed in less time than many of the traditional replacement techniques.
评估一种将脱出的瞬膜腺固定于瞬膜软骨且不影响瞬膜活动的新方法。
进行一项前瞻性临床试验，采用不可吸收缝线将脱出的腺体固定于第三眼睑的软骨。该研究纳入了10只犬的15只眼。用4-0尼龙缝线从第三眼睑前表面穿过软骨基部至后表面，然后在脱出腺体上方和周围的结膜下环形穿行。缝线再穿过软骨回到第三眼睑前表面。随着缝线缓慢收紧，将腺体复位至正常位置，然后在瞬膜前表面打结。
在数周时间内，腺体体积缩小并恢复正常外观。除一只外，所有腺体在2周~33个月的随访期内均保持在位。
该方法可使腺体回到瞬膜后方的正常位置，产生可接受的美容效果。与传统的固定于眶缘的方法相比，该技术的优势在于第三眼睑保留了正常活动，因而保留了其保护功能。该方法一旦掌握非常迅速，且比许多传统复位技术所需时间更短。
