目的 探讨经冠状入路眼眶减压术 (coronalsurgicalapproachtoorbitaldecompression ,CSAD)的临床疗效。方法 选择双眼甲状腺相关眼病 (thyroidassociatedOphthalmopathy ,TAO )患者 2 6例 (5 2眼 ) ,行CSAD手术 ,其中二壁减压 2 0例 ,三壁减压 6例。结果 手术前平均睑裂宽度14 5mm ,手术后 11 7mm ;术前平均眼球突出度 2 3mm ;术后平均眼球突出 16 8mm ,平均后退6 2mm ,术后视力提高 18例 (3 6眼 )无变化 7例 (14眼 )减退 1例 (2眼 ) ;术后复视改善 17例 ,无变化 6例 ,复视症状加重 3例。结论 CSAD具有减压效果明显 ,并发症少 ,术后眼部无瘢痕等优点。
Objective To investigate the clinical efficacy of coronal orbital alab orbital decompression (CSAD). Methods Twenty - six patients (52 eyes) with bilateral thyroid associated ophthalmopathy (TAO) were selected underwent CSAD surgery. Among them, 20 cases of bilateral wall decompression and 6 cases of three wall decompression were included. Results The average palpebral fissure width before operation was 14 5 mm and postoperative 11 7 mm. The mean preoperative anastomotic protrusion was 23 mm. The average postoperative protrusion was 16 8 mm and the average receding distance was 6 2 mm. There was no change in postoperative visual acuity in 18 cases (36 eyes) Seven cases (14 eyes) decreased in 1 case (2 eyes). Seventeen cases showed improvement after operation, 6 cases did not change, and 3 cases showed symptoms of diplopia. Conclusions CSAD has the advantages of obvious decompression effect, less complications and no post-operative scar.
