Endoscopic endonasal versus transfacial approach for blowout fractures of the medial orbital wall
No full textAbstract
In the last decades, the introduction of computed tomography has allowed an increase in the number of diagnosed fractures of the medial orbital wall. To repair medial wall fractures, many surgical techniques have been proposed (1), each one with its advantages and disadvantages. In this study, we compared endoscopic endonasal and transcutaneous reduction approaches in terms of surgery time and clinical outcome. Between 2001 and 2005, 81 patients with orbital wall fractures were treated at our department. Among these 81 patients, 24 (29.63%) were affected by a medial orbital fracture. Patients with fracture to both floor and medial walls underwent floor reduction by a transcutaneous subpalpebral approach (n = 9, 11.1%), whereas patients with isolated medial wall fracture underwent medial wall reduction by a transcutaneous subpalpebral approach using alloplastic implants (n = 8, 9.88%) or were treated by endoscopic approach (n = 5, 6.17%). After surgery, oculomotor function improved in all 22 patients. None of the patients had complications. Computed tomography revealed a well-consolidated site of fracture in both endoscopic endonasal and transcutaneous approaches. The average operating time for endoscopic endonasal and transfacial approach was 50 and 45 minutes, respectively. In this paper, the author proposed a results comparison between the endoscopic approach and the transcutaneous one
Orbital volume after Le Fort III advancement in craniosynostosis
No full textThere are no quantitative standards for the volumetric measurements of the orbit after Le Fort III advancement. CT Scan images have given the opportunity to compare with accuracy the real anatomical changes, thus the functional improvements, resulted after a surgical treatment. Pre-operative (T0) and post-operative (T1: 6 months after surgery) 3D craniofacial CT scans of the subjects were collected and retrospectively analysed. Image segmentation of the anatomic structures of interest and the 3D graphic rendering were done by using the Dolphin Imaging Plus (TM) 11.0 software. This study showed that the orbital advancement in Caucasian subjects after Le Fort III advancement was significant and produced a critical augmentation of the orbital volume and correction of the ocular bulb proptosis

No full textThe present is a retrospective study on the stability of Le Fort III midface advancement with distraction in craniofacial dynostosis. Twenty-six surgical procedures for midface advancement were performed between 2000 and 2009. Fourteen consecutive patients who underwent Le Fort III osteotomy with midface advancement using a rigid external distraction device (Synthes) in the department of Maxillo-Facial Surgery of the University "Sapienza" of Rome. In this study eight patients (n= 3 females. n= 5 males) affected by craniofacial dysostosis (5 Crouzon, 3 Apert, 1 Pfeiffer syndrome and 1 other) were selected on the basis of age and radiological documentation. The mean age at the time of the procedure was 8.6 years and all the patients had at least 1 year of follow-up after distraction. Bone growth after midface advancement is limited and, as reported in the literature, almost no spontaneous growth is present due to the intrinsic nature of malformations
Orbital trauma with eyeball injuries; diagnostic strategy and combine surgical-prosthetic reconstructive treatment
No full textThe timing for the treatment of orbital fracture addresses to the immediate reduction and fixation whenever possible. Sometimes treatment can be delayed because of patient general conditions or associated other injuries. In these cases bone consolidation occurs in the wrong position. As a consequence both aesthetic and functional impaired healing can occur. The most common complaint in patients presenting this pathologic healing is the alteration of the visual field consisting in strabismus, diplopia. On the aesthetic side, we can observe orbital dystopia both on the frontal plane and sagittal plane. Enophtalmus or exophtalmus are very frequent clinical features of these patients. When direct injuries to the eyeball occur these can be responsible for impairment of view or eyeball size and fatally loss. The most common complaint in patients presenting this pathologic healing is the alteration of the visual field consisting in strabismus, diplopia. On the aesthetic side, we can observe orbital distopia both on the frontal plane and sagittal plane. Enophtalmus or exophtalmus are very frequent clinical features of these patients
