title: Transnasal transsphenoid approach: a minimally invasive approach for removal of cavernous haemangiomas located at inferomedial part of orbital apex.
abstract: Ten patients complaining of visual impairment, proptosis or ocular pain, were selected for transnasal transsphenoid microsurgical approach to address cavernous haemangiomas located at inferomedial part of orbital apex. Via this approach, the contents of orbital apex were clearly illuminated and exposed as large as the surgical removal required. All tumours were identified under frameless image-guided neuronavigation and removed completely without any complications and recurrence in a mean of 12.2 months follow-up. It is concluded that a transnasal transsphenoid microsurgical approach is a minimally invasive surgery for cavernous haemangiomas located at inferomedial part of orbital apex.
