Orbital trauma may cause significant facial deformities
while also affecting eyesight and the nerve system of the face.
Most orbital floor fractures are open defect injuries, which
separates them from other face bone fractures [10].
Forty percent of the craniofacial injuries are orbital
fractures; the orbital floor, because it is the thinnest of the
orbit's four walls, is the one that sustains injuries the most
often. The relevant literature indicates that these fractures
account for 67.84% of all instances of the bones around the
eye. Generally, the fracture of these bones related to orbital
floor may be divided into isolated and complex fractures; the
first is isolated to bones around orbit, while other one is
involving other around orbit bones a: cheek bones, forehead
bones and naso-ethmoidal [5].
Objective: Our goal of the research to assess whether
titanium mesh implants or cranial bone grafts were more
appropriate for internal orbital repair for clean rupture fractures.
Methods: The case series method was utilized in this
prospective and retrospective analysis on patients who had
internal orbital reconstruction using titanium mesh (0.4mm
thickness) or a skull grafting (external table) at Sohag University
Hospital and Luxor University Hospital for 2 years
Study.
Included 40 men and women suffering from ex-plosive
orbital fractures. Patients were divided into 20 patients who
underwent surgery using titanium mesh (Group A) and 20
patients who underwent surgery using autologous bone graft
(Group B).
Results: Relationship between before and after surgery
with titanium mesh ophthalmic problems did not show a
statistically significant phenomenon (blindness), and the data
were statistically significant (double vision, motion restriction,
suborbital hypoesthesia, vertical abnormality), but in case of
relation between autogenous bone and titanium mesh ophthalmic
problems in preoperative surgery do not show statistically
significant values for all parameters.
Conclusions: Autologous bone grafts do not cause immunological
problems, but the number of donor sites is limited.
There may also be problems related to pain in the second site,
mismatch of mechanical properties of the host bone, and
123
tendency to resorption. Titanium mesh, a synthetic biomaterial,
is an expensive but good alternative and can overcome these
limitations.
