An Alternative Route for Entrapped Inferior Orbital Nerve in Orbital Floor Fracture
Abstract
:Case History
- Both nasal bones
- Anterior, medial, and lateral wall of the right maxillary sinus with displaced fragments with hemosinus, fracture line passing through the right infraorbital foramen
- Lateral wall of right orbit
- Right zygomatic process
Discussion
Infraorbital Nerve Anatomy
- A bifurcated nerve running in two separate osseous canals and emerging out of two separate infraorbital foramina [15].
- The nerve may run in a canal (complete roof present) or canal plus groove.
- The foramen may be oval, round, or semilunar.
- There may be accessory or supernumerary infraorbital foramina. Kazkayasi et al. found them to be doubled in 5%, tripled in 5%, and more than three times in 0.3% [16].
Surgical Management of Orbital Floor Fractures
- Enophthalmos of more than 2 mm at any time during first 6 weeks
- Diplopia persisting for more than 2 weeks
- Large orbital floor defect of 1 cm2 and above
- Significant hypoglobus
