A case report of inferior oblique reattachment after Inferomedial Orbital Wall Reconstruction from Total Maxillectom

ABSTRACT

@#The detachment and reattachment of inferior oblique (IO) have been done by ophthalmologists in inferomedial orbital wall fracture repair to avoid inducing a new diplopia in patients post-operatively. However, doing them in orbital wall reconstruction in patient who underwent maxillectomy for a malignancy has not been described yet. We describe a case where a disinserted inferior oblique was reattached after titanium mesh implantation to prevent diplopia after the surgery. This is the case of a 40-year-old male diagnosed with recurrent bilateral nasomaxillary ameloblastoma who underwent total maxillectomy of the right with removal of the inferomedial orbital wall, and detachment and reattachment of inferior oblique with no resulting inferior oblique palsy and diplopia from hypotropia or incyclotorsion. This is the first report, to our knowledge, to describe reattachment of IO in its approximate insertion during reconstruction of the inferomedial orbital wall after total maxillectomy from a malignancy with no resulting diplopia.
