方法：回顾性分析114例经手术后病理组织学证实的眶周皮样囊肿患者的临床资料。所有患者均行彩色多普勒超声检查，部分患者行CT检查。根据肿物的部位设计不同的手术切口。

结果：选取114例患儿中，右眼61例，左眼53例。肿物位于眶颞上缘68例(59.6%)，眶上缘27例(23.7%)，眶内上缘13例(11.4%)，眶内下缘5例(4.4%)，眶下缘1例(0.9%)。肿块与骨膜粘连紧密者49例。彩色多普勒检查示肿物边界清楚100例(87.7%)，低回声者105例(92.1%)，回声均匀者61例(53.5%)，伴有液性暗区者4例，囊肿内部无血彩者107例(93.9%)。行CT检查者40例中，CT值范围-55～ 32Hu。肿物周边骨壁破坏7例。术中根据肿物的部位行不同的手术切口。眉弓切口72例，上睑双重睑切口10例，囊肿部位顺皮肤方向皮肤切口30例，穹隆切口2例。所有患者术后随访3mo～4a，均无明显手术并发症，无复发。

结论：联合彩色多普勒及CT检查，可术前对儿童眶周皮样囊肿进行准确定性、定位诊断。巧妙利用肿块位置设计手术切口，完整摘除囊壁是达到术后更好的美容效果，避免复发的关键。

METHODS: The clinic data of 114 cases which dermoid cyst was illustrated by pathological histology after surgery was retrospectively analyzed. All patients were performed color Doppler ultrasound and some patients were underwent CT. Surgical incisions were designed according to the position of cyst.

RESULTS:Among 114 cases, 61 cases in right eye, 53 cases in left eye. The location of cyst was at superior temporal in 68 cases(59.6%), supraorbital in 27 cases(23.7%), medial superior in 13 cases(11.4%), medial inferior in 5 cases(4.4%), infraorbital in 1 case(0.9%). Cyst was adhered to periostea in 49 cases. Color Doppler ultrasound showed the clear cyst boundary in 100 cases(87.7%), hypoecho in 105 cases(92.1%), homogeneous in 61 cases(53.5%), fluid dark area in 4 cases and no-blood flow inside cyst in 107 cases(93.9%). Forty patients were performed by CT, and CT value ranged from -55～32Hu and bony destruction surrounding cyst was showed in 7 cases. According to the position of cyst, eye brow incision were designed in 72 cases, upper eyelid crease incision in 10 cases, skin incision upper the cyst in 30 cases, fornix incision in 2 cases. All patients were followed up for 3mo～4a, no complications and recurrence.

CONCLUSION:Combination with color Doppler and CT can make an accurate and locative diagnose of periorbital dermoid cyst in children before surgery. Surgical incision designed by lesion position and complete removal of the cyst wall is the key to get better cosmetic appearance and avoid recurrence.
