Zachowanie słuchu i czynności nerwu twarzowego podczas operacji małych guzów kąta mostowo-móżdżkowego z zastosowaniem poszerzonego dostępu przez środkowy dół czaszki Preservation of hearing and facial nerve functions during the extended middle fossa approach operation of small cerebellopontine angle tumors

چکیده
Wyniki: Wśród pacjentów w stadium zaawansowania choroby T1 i T2 słuch zachowało odpowiednio 67.4% oraz 37.5% (p=0.12). Stwierdzono istotnie statystycznie znaczącą korelację pomiędzy lepszymi wynikami badań audiologicznych a stosunkiem guza do pajęczynówki (łatwa do zidentyfikowania płaszczyzna preparacji). Nie stwierdzono istotnego statystycznie wpływu monitorowania śródoperacyjnego na wyniki leczenia (53% versus 50%, p=0.86). Monitoring zastosowano w 43.3% przypadków.

متن کاملPreoperative identification of the facial nerve achieved using fast spin-echo MR imaging: can it help the surgeon?
In this issue of the AJNR, Dr. Sartoretti-Schefer et al (page 810) present a novel study investigating imaging of the facial nerve and its relationship with acoustic tumors. They point out that it has been reported in the literature that the facial nerve lies anteriorly to the tumor 98% of the time. With the T2-weighted fast spin-echo MR technique, they could identify consistently the entire co...
