RESUMO
Aims and Objective: The purpose of this study was to assess the use and accuracy of the titanium micromesh for primary internal orbital reconstruction in cases of either pure or impure orbital blowout fractures. Design: Retrospective case series of 21 patients with a mean follow-up of 12 months. Place: Department of Dental Surgery of a teaching tertiary medical college Hospital. Material and Methods: Twenty-one consecutive patients who underwent surgical reconstruction of orbital floor/or Combination of floor and rim fractures using titanium micromesh. Outcome and Evaluation: Persistence of diplopia, orbital dystopia, implant extrusion, enophthalmos, infection, and complications. The recorded data included age, gender, cause of trauma, diplopia, enophthalmos, ocular motility, preoperative orbital PNS/CT, and postoperative paranasal sinus view skull preoperative and postoperative ophthalmological examination. Results: Most of the patients were males and resulted from trauma inflicted during RTA, sport injuries or assault. The most Common fracture pattern was impure Blow out fractures, and commonly associated other facial fractures were midfacial fractures. Clinical examination along with diagnostic aids such as computed tomography of orbital fractures was used. Orbital floor exploration was performed in 21 cases due to functional or aesthetic deficits. All orbital floor bone defects required reconstruction. In these cases, orbital floor was reconstructed with .3 mm titanium micromesh implant. We did not encounter any major complications related to the incisions or implant material, though sample size was small. The rate of complication in which correction was difficult (diplopia) was lower [4%, 1 case]. Conclusion: Titanium mesh gives excellent result in orbital floor fractures. Surgical anatomical landmarks knowledge is very important to prevent any intra- or postoperative complications.
