“…The prognostic utility of intra-operative facial nerve monitoring during neurotologjcal, neurosurgical and skull base procedures has been suggested by numerous articles in the world literature (Delgado et al, 1979;Lye et al, 1982;Moller and Jannetta, 1984;Kartush et al, 1985;Prass and Luders, 1986;Prass et al, 1987;Harner et al, 1988;Silverstein et al, 1988;Benecke et al, 1991;Kartush et al, 1991;Magliulo et al, 1994a). Adjunctive information is available on its potentially useful ability in predicting the facial nerve function at the end of acoustic tumour removal (Beck et al, 1991;Kirkpatrick et al, 1991;Berges et al, 1993;Silverstein et al, 1994).…”
