As surgical approaches accessing orbital apex carry .significant risk and require strong expertise and skills, it is important for surgeons to share their know-how and to evaluate the surgical interventions they practiced on a number of patients. We retrospectively studied 9 cases of orbital apex lesions which were excised via posterior lateral orbitotomy.

AIM: To review imaging characteristics and surgical outcomes of orbital neurilemmoma. METHODS: Retrospective review of 21 patients with orbital neurilemmoma managed at the Zhongshan Ophthalmic Center of Sun Yat-sen University from June 2005 to December 2016. All patients underwent surgical excision following preoperative imaging including ultrasonography, computed tomography(CT) and magnetic resonance imaging(MRI).RESULTS: Among these patients, 11 were male and 10 were female, with age ranging from 12 to 75y(average, 40.3 y). Ultrasound of the orbit showed a roundish well-demarcated orbital mass with low or middle internal reflectivity in each case. Dark inner liquid fields were detected in 28.6% of these cases. Doppler ultrasound demonstrated blood flow signals in these masses. CT showed that the tumors were either homogeneous or heterogeneous. MRI of T1 WI revealed isointense or hypointense tumors, while the T2 WI indicated heterogeneous hyperintense lesions. Gd contrast MRI demonstrated heterogenous or homogeneous enhancement initiating from the wide area of the lesion. Six patients underwent lateral orbitotomy and 15 anterior orbitotomy. All tumors were completely removed. After a mean followup of 1.8 y, 3 patients experienced reduced vision while the remaining 10 patients showed improved vision after surgery. One patient experienced a mild limitation of upward motility. No recurrence occurred. CONCLUSION: Orbital neurilemmoma is a relatively rare, benign orbital tumor. Effective diagnosis requires a combination of ultrasonography, CT and/or MRI. These imaging techniques are also vital to differentiate neurilemmomas from other orbital masses like that of cavernous hemangiomas and *** treatment requires complete resection of the neurilemmomas as performed either by lateral or anterior orbitotomy. Recurrence is rare after complete removal.

Cavernous Hemangioma of the Bony Orbit

眼科学报 2005年第3期 19-23页

作者： Jianhua Yan, Yu Cai, Zhongyao Wu, Ji Han, Youjian Pang Eye Hospital, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060 China. Eye Hospital Zhongshan Ophthalmic CenterSun Yat-sen UniversityGuangzhou 510060 China

Purpose: To study the clinical features, diagnosis and management of intraosseous cavernous hemangioma of the orbit. Methods: Five cases of intraosseous cavernous hemangioma seen in our hospital from Jan 1, 1986 to Dec 31, 2000 were reviewed. Results: Among all five cases, two were male and three were female. The mean age was 47.6 years old, ranging from 39.0 to 55.0 years. The left orbit was affected in 4 cases and the right one in 1 case. The bony involvement occurred in frontal bone (two cases), zygomatic bone (two cases) and sphenoid bone (one case). A painless, slowly enlarging hard bony mass fixed to the bone with no pulsations was the main clinical sign. The x-ray and CT appearance of intraosseous cavernous hemangioma of the orbit were characteristic and usually diagnostic. The differential diagnosis of it included fibrous dysplasia, eosinophilic granuloma, multiple myeloma and metastatic carcinoma. Treatment is local removal of the bone containing the tumor. Conclusions: Intraosseous cavernous hemangioma is a rare tumor of the orbit and usually has good surgical result. Eye Science 2005;21:147-151.
