Orbital marginotomies

Background and objectives: Orbital tumours can be approached in several ways, but the orbital rims are often an obstacle to the surgeon’s direct visualization and access, especially if the lesion is deep within the orbit. Orbital osteotomies allowing removal of various segments of the orbital rim improve exposure and control. The author’s aim is to review a series of 8 cases of orbital lesions in which surgical access included temporary removal of orbital rim segments.

Methods: A retrospective review of 8 cases of orbital tumours was made. In all cases tumour approach was based on temporary removal and replacement of orbital rim segments.

Results: Out of the 8 tumours, 6 were approached using a lateral marginotomy (75%), 1 using a combined lateral marginotomy and pterional approach (12.5%) and 1 using a superior marginotomy. Functional and cosmetic results were good in all cases and no complications were found.

Conclusions: Orbital marginotomies are a useful tool for the surgical management of orbital tumours. An appropriate temporary marginotomy improves exposure and access to the operating site. As the fragments of bone are replaced at the end of the procedure, no cosmetic or functional damage is caused.
