Morphometric study of Intratemporal course of facial nerve in relation to pneumatization of temporal bones—An original study

DiscussionThe distal segment of nerve is most commonly injured during otologic surgeries. Incus pointer can be considered as a landmark to identify the facial nerve. Accordingly the tympano mastoid part of the facial nerve can be divided into proximal, distal and stylomastoid foramen segments. Radiological evaluations such as Computed Tomographic (CT) imaging techniques and MRI techniques like FIESTA (Fast Imaging Employing Steady-state Acquisition) have become popular in identifying these segments. The morphometric values of facial nerve provided in the present study can help in assessment during procedures, like end to end anastamosis and cable nerve graft repairs in iatrogenic injuries.
