Of patients with large tumours, 22% had good facial function (grade 1 and grade 2), 37% had moderate function (grade 3 and grade 4) and 41% had poor function (grade 5 and grade 6). Useful postoperative hearing was preserved in 21% of the 47 patients with tumours &lt;3\u2003cm and useful preoperative hearing. In the last 5\u2003years the authors have been operating in conjunction with an ear, nose and throat surgeon (PAB) trained in base\u2010of\u2010skull surgery. Over this period, useful hearing was preserved in 32% of patients with small and medium\u2010sized tumours and useful preoperative hearing.<\/jats:p><jats:p><jats:bold>Conclusions:\u2003<\/jats:bold> Tumour size was an important predictor of the postoperative facial and cochlear nerve function. The multidisciplinary approach to these tumours offers better results.
