Observation on the efficacy of surgeries for the treatment of orbital floor fractures associated with inferior rectus incarceration

Abstract

Objective To observe the clinical efficacy of surgery for the treatment of orbital floor fractures associated with inferior rectus incarceration. Methods The data of 6 eyes of 6 patients with orbital floor fractures and incarceration of the inferior rectus from Jun. 2013 to Jun. 2014 were analyzed retrospectively. All cases were with diplopia and restriction of upward motility, without enophthalmos, and underwent orbital fracture reduction surgery. The orbital contents protruding into the cavity of the maxillary sinus were returned, and Medpor was implanted for the reconstruction of the inferior orbital wall. Visual acuity, motility and diplopia and CT results pre-and post-operatively were observed and compared. Results All patients were followed up for 3 months. Motility recovered and diplopia disappeared in 5 cases within 2 weeks after injury and 1 patient received surgery more than 2 weeks after injury showed partial improvement of motility and diplopia. Post-operative CT showed the pavimentum orbitae was intact and the inferior rectus reduction. The visual acuity of all patients were not reduced. Conclusion Orbital floor fracture reduction surgery can effectively correct the restricted motility and diplopia of orbital floor fractures and inferior rectus incarceration. Earlier operation might bring more benefits. Key words: Orbital fractures, floor; Inferior rectus incarceration
