چکیده

OBJECTIVE: We aimed to establish the frequency of postoperative bony dehiscence overlying the mastoid portion of the facial nerve after round window membranous cochleostomy using high-resolution computer tomography, and to ascertain whether this was associated with a higher incidence of facial nerve injury compared with other studies. We also evaluated the usefulness of the St Thomas’ classification in predicting the possibility of performing round window insertions.

Magnetic resonance (MR) is the preferred technique in patients with sensorineural hearing loss and/or vertigo; however, computed tomography (CT) is used to evaluate the IAC or facial nerve canal. Three types of aplasia or hypopl...

ANATOMICAL VARIATIONS OF THE CHORDA TYMPANI NERVE

The author studied anatomical variations of the origin of the chorda tympani nerve from the mastoid portion of the facial nerve. The studies were performed on 200 specimens of human temporal bone. It was found that the chorda tympani may arise from the facial nerve in three levels: most commonly from the mid third of its mastoid segment (70%), less commonly from the proximal third (20%), an...
