Abstract

Various spacers are used to achieve a higher position for the lower eyelid and reduce the degree of lagophthalmos in chronic facial palsy (CFP). Most authors consider a hard palate mucoperiosteal graft (HPG) to have major advantages over other spacers, particularly minimal shrinkage in the postoperative period. However, only a few publications report possible HPG shrinkage, and their findings are based on subjective assessments.

Objective: The study aimed to perform clinical and echographic assessment of the lower eyelid tissues after the use of HPG for the correction of paralytic lagophthalmos (PL).

Material and methods: The study included 30 patients (30 eyelids) with CFP and PL. The work involved measurement of biometric parameters of the palpebral fissure and ultrasound examination of the lower eyelid (high-resolution grayscale B-scan ultrasonography, color Doppler mapping with 3D mode, echodensitometry, and ultrasound biomicroscopy) at 6 and 12 months after HPG placement.

Results: We observed significant changes in palpebral fissure parameters and improvement in the state of the cornea. The distance from the corneal light reflex to the lower eyelid margin (MRD2) decreased from 7.0±1.2 to 5.7±0.8 mm (p<0.001) after surgery, and the degree of lagophthalmos decreased from 2.75 [0.5; 6.0] to 1.0 [0.0; 3.0] mm (p<0.001). At 6 and 12 months, HPG thickness changed from 2.89±0.65 to 2.82±0.69 mm (p=0.68), height from 6.01±0.47 to 5.84±0.54 mm (p=0.449), and volume from 0.56±0.05 to 0.52±0.74 cm³ (p=0.398); these changes were not statistically significant. We identified features of HPG vascularization up to 12 months after HPG placement. The study also describes the complications of HPG placement.

Conclusion: The use of HPG for the correction of PL showed high effectiveness and safety. There was no graft shrinkage during the 12-month follow-up period. The study demonstrates the capabilities of ultrasound methods for assessing the dimensions and biointegration features of HPG.

粘骨膜移植矫治麻痹性眼后斜视。

在慢性面瘫（CFP）患者中，为了使下眼睑达到较高的位置，减少眼球lagoflos的程度，使用了各种各样的间隔器。大多数作者认为硬腭粘骨膜移植物（HPG）比其他垫片具有主要优势，特别是术后收缩最小。然而，只有少数出版物报道可能的HPG萎缩，他们的发现是基于主观评估。目的：对HPG矫正麻痹性眼lagmomos （PL）后的下眼睑组织进行临床及超声评价。材料和方法：本研究包括30例CFP和PL患者（30眼睑），工作包括在HPG放置后6个月和12个月测量睑裂的生物特征参数和下眼睑超声检查（高分辨率灰度b超、3D模式彩色多普勒成像、超声密度测量和超声生物显微镜检查）。结果：术后睑裂参数明显改变，角膜状态明显改善。角膜光反射至下睑缘的距离（MRD2）由7.0±1.2 mm降至5.7±0.8 mm (ppp=0.68)，高度由6.01±0.47 mm降至5.84±0.54 mm (p=0.449)，体积由0.56±0.05降至0.52±0.74 cm³（p=0.398）；这些变化没有统计学意义。我们确定了HPG植入后12个月的血管化特征。该研究还描述了HPG放置的并发症。结论：应用HPG矫正外伤性脓疱具有较高的疗效和安全性。随访12个月无移植物萎缩。该研究证明了超声方法评估HPG的尺寸和生物整合特征的能力。
