Abstract
The present study was conducted to clinically and radiographically evaluate the use of antero-lateral of maxillary sinus wall in reconstruction of orbital floor fractures and to determine if it can be considered as a useful method to correct diplopia enophthalmos and restriction in ocular mobility.
Ten patients with orbital floor fracture either isolated orbital floor fracture or associated with other maxillofacial fractures were selected for this study proved that the patients were complaining of either diplopia or enophthalmos or restriction in ocular mobility.
Both clinical and radiographic examinations were performed for each patient. Clinically, each patient was examined to detect if the patient has diplopia, enophthalmos or restriction in ocular movements. Before maxillofacial evaluation each patient underwent ophthalmological evaluation to detect if the patient was in need of any urgent intervention like monocular diplopia which indicates that the patient may have lens dislocation or retinal detachment, or if the patient had retrobulbar haemorrhage which needs urgent intervention to evacuate this hematoma by performing lateral canthotomy cantholysis and giving the patient mega dose of corticosteroids. Clinical evaluation was performed also to detect if the patient had any associated injuries either in facial skeleton or outside the facial skeleton.
Radiographic examination was performed to detect fractures that can’t be detected clinically. Radiographic examination was in the form CT scan which considered to be the corner stone in diagnosis of orbital floor fractures.
All the patients were operated upon for reconstruction of the orbital floor defects by antero-lateral wall of maxillary sinus from contralateral side. A subtarsal approach was done to expose the infraorbital rim and to explore the orbital floor.
Forced duction test was done to detect muscle entrapment and then the herniated tissues were released.
The graft harvested from contralateral side by piezosurgery and adapted to the orbital defect with no further mean of fixation, the wound was closed in two layers and the donor site covered with collagen membrane and suturing was done.
Result of study:
The antero-lteral wall of maxillary sinus is a good option in reconstruction of orbital floor defect smaller than 2.5 cm2.
