안와 파열 골절 치료 시 삽입물 종류에 따른 후유증 비교 = Comparison of Sequelae According to the Types of Implants in Blow-Out Fracture

다국어 초록 (Multilingual Abstract)

Blow out fracture can present tenderness,
swelling, enophthalmos, extraoccular muscle limitation,
paresthesia, diplopia according to severity of injury, so
reconstruction of blow out fracture is important. Orbital
soft tissue should be in orbit and defected orbital wall
should be corrected by autologus tissue or alloplastic
implants. Every implants have their merits and faults,
every implants are used various. This study was designed
to compare the sequelae of blow-out fracture repair using
the alloplastic implants: micro-titanium mesh(Micro Dynamic
titanium mesh® , Leibinger, Germany), porous polyethylene
(Medpor® , Porex, USA), absorbable mesh plate(Biosorb
FX® . Bionx Implants Ltd, Finland).
Methods: Between January 2006 and April 2008, 52
patients were included in a retrospective study analysing
the outcome of corrected inferior orbital wall fracture with
various kind of implants. Implants were inserted through
subciliary incision. Twenty patients were operated with
micro-titanium mesh, fourteen patients with porous polyethylene
and eighteen patients with absorbable mesh plate.
In comparative category, enophthalmos, diplopia, range of
motion of extraoccular muscle, inferior orbital nerve injury
were more on frequently statistically in patients.
Results: Fourteen of 18 patients underwent surgical
repair to improve diplopia, 11 of 17 patients to improve
parasthesia, 11 of 15 patients to improve enophthalmos,
8 of 9 patients to improve extraoccular muscle limitation.
Duration of follow-up time ranged from 6 months to 12
months(mean, 7.4 months). There was no statistic difference
of sequelae between micro titanium mesh and
porous polyethylene and absorbable mesh plate in blowout
fracture, inferior wall.
Conclusion: There is no difference of sequelae between
micro-titanium mesh, porous polyethylene and absorbable
mesh plate in blow-out fracture, inferior wall. The other
factors such as defect size, location, surgeon's technique,
may influence the outcome of blow-out fracture repair.
