OUTCOMES OF TREATMENT FOR TRAUMATIC ORBITAL FLOOR FRACTURES UTILIZED WITH PREFORMED TITANIUM MESH ON THREE-DIMENSIONAL PRINTED MODELS

Abstract

Objectives: Describe the clinical and radiological features while assessing the treatment outcomes associated with orbital floor fractures in midface bone fractures. This study utilizes a preformed titanium mesh approach implemented on a three-dimensional (3D) printed model, conducted at the Department of Maxillofacial Surgery, Ho Chi Minh City Dental Hospital.

Methods: This study was conducted involving 19 patients, comprising 11 males and 8 females within the age range of 20 to 42 years. These individuals were diagnosed with orbital floor fractures and treated at the Department of Maxillofacial Surgery, Ho Chi Minh City Dental Hospital from November 2021 to March 2023.

Results: Common clinical manifestations: bilateral asymmetry of zygomatic bone (94.7%), step defects or bone discontinuity around the orbital rim, zygomatic arch (94.7%), differences in proptosis (94.7%), differences in downgaze of occults (89.5%). In terms of functional outcomes, at the time of hospital discharge, 10 out of 19 patients (52.6%) exhibited favorable results, while 09 out of 19 patients (47.4%) demonstrated fair results. After a 6-month follow-up, 18 out of 19 patients (94.7%) experienced favorable results, with only 1 out of 19 patients (5.25%) achieving fair results. Evaluation of aesthetic outcomes: 13 out of 19 patients (68.4%) demonstrated favorable results upon discharge, whereas 06 out of 19 patients (31.6%) exhibited fair results. Following the 6-month postoperative period, 17 out of 19 patients (89.5%) displayed favorable results, while 1 out of 19 patients (5.25%) demonstrated fair results.

Conclusion: The surgical management of orbital floor fractures utilizing preformed titanium mesh on three-dimensional (3D) models has demonstrated favorable outcomes in both functional and aesthetic domains. Notably, no instances of failure have necessitated the reconfiguration of the preformed titanium mesh on the 3D models.
