“…Among the cases who underwent transmastoid approach for tumor removal at GG or labyrinthine segment, hearing remained unchanged in 62.5% of the cases, hearing change of the remaining 37.5% cases was not more than 10 dB. Actually, transmastoid approach was ever used to decompress the facial nerve from stylomastoid foramen till labyrinthine segment for Bell's palsy, and hearing was affected mildly in minority cases [17][18][19].…”

“…Horn et al (1986), in their study ''The supratubal recess in cholesteatoma surgery,'' mentioned that the facial nerve courses 2 to 3 mm anterior to the cochleariform process before joining the geniculate ganglion. Earlier studies by Yanagihara et al (1979) and Goin (1982) on the subject of decompression of the facial nerve in Bell's palsy mentioned that one-half of the length of the TSFN is encased in bone from the geniculate ganglion to the cochleariform process.

There is a conroversy in the literature about the length of the proximal tympanic segment of the facial nerve (PTSFN). The objective of the current study is to measure the length of the tympanic segment of the facial nerve (TSFN) and of its proximal (PTSFN) and distal (DTSFN) segments, in normal human temporal bones. Moreover, we will explore if these lengths are correlated. If a form of a functional relationship can be established, it could offer insights in partially predicting or estimating the length of the TSFN as well as of its proximal and distal portions. Direct measurements were obtained in 40 normal human temporal bones, which were examined by surgical dissection. Relationships between these measurements were established using Pearson's correlation method (two-tailed). The length of the TSFN was on average 10.97 mm. The length of the PTSFN was on average 5.25 mm and of the DTSFN was 5.72 mm. No significant statistical differences according to gender or side (right or left) were detected. It was determined that the length of the TSFN was in linear correlation with positive direction with its proximal (PTSFN) and distal (DTSFN) segments. Also the PTSFN length was in linear correlation with positive direction with the DTSFN length. The length of the PTSFN comprises about one-half of the TSFN length. The existence of a definite correlation between the lengths of the TSFN, PTSFN, and DTSFN implies the existence of a form of functional interrelationship. This could facilitate prediction and identification of the TSFN and PTSFN lengths from the easily identifiable DTSFN length during surgery.

“…Yanagihara and his colleagues [17] proposed surgical treatment before day 30 in patients with more than 95% degeneration. However, Gantz et al [15] recommended surgical decompression before day 14.…”

“…The surgical approach has been used by Yanagihara et al [17], and we have also described the surgical procedures and possible complications in our previous papers [19,20]. To expose the geniculate ganglion and labyrinthine segment adequately, the incus is removed temporarily and then repositioned exactly.…”
