OBJECTIVE To develop and evaluate a minimally invasive technique of lateral orbitotomy that provides improved orbital access with fewer complications. METHODS A cadaver study was undertaken to develop a technique of transconjunctival lateral orbitotomy that preserves the structural integrity of the eyelid support system and provides extended access to the orbit from floor to roof. We then eva...

We conducted a retrospective analysis of 22 patients having orbital penetrating gunshot wounds treated over a 4-years period. The neurological status and the site of injury for each patient are evaluated in this study. We propose a practical protocol in the management of these orbital foreign bodies. Surgical treatment was performed in 4 patients (had functional deficit) with medial orbitotomy ...

AIMS To present transcaruncular medial orbitotomy as the preferred approach to manage frontoethmoid mucoceles. METHODS 11 patients with frontoethmoid mucoceles received transcaruncular orbitotomy from 2000 to 2002 at the National Taiwan University Hospital. The incision was made through the caruncle to explore the medial wall periosteum. Then the periosteum was opened and extended to provide ...

Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy the right eye, wide retrobulbar anatomy exposure, dissection structures, identification and distal section optic nerve followed by anastomosis either vicryl (group 1) or fibrin glue 2). Electroretinography recording was performed bef...

CASE REPORT A 74-year-old male presented with an orbital tumor located in the left lacrimal fossa. Ocular examination showed hypotropia, exophthalmos and palpebral ptosis. DISCUSSION Removal of the tumor was performed by a lateral orbitotomy. The histopathologic study showed a tumor consistent with an adenocarcinoma of the lacrimal gland with apocrine differentiation.

purpose:  to report a case of lymphangioma in the lacrimal gland. case report: a 6-year old boy with acute proptosis and inferonasal displacement of the globe was referred.  in ct-scan revealed a heterogenous enlargement of the lacrimal gland. steroid therapy did not lead to a significant improvement. during surgical exploration, a dark black liquid was extracted from the site of the lacrimal g...

The cranio-orbital approaches have been successfully employed for resection of tumours involving the orbit and anterior skull base. With modifications of the cranio-orbital bone flap (changing the position and size of the flap), incorporation of posterior orbitotomy or zygomatic osteotomy, the cranio-orbital approaches can be specifically tailored to optimize the access to tumours located in a ...
