Our objective is to prospectively report very early complications and outcomes of cerebellopontine angle (CPA) surgery. Between January and August 2007, 72 patients were operated on by different transpetrosal approaches in a tertiary referral center. During preoperative assessment, facial nerve function (House-Brackmann grading system), the presence of vertigo or tinnitus and caloric test results were recorded and correlated with complications and symptoms occurring daily from day (D) 1 to D 8. The overall number of complications did not differ from those of former retrospective studies; nevertheless, the prospective feature of this study prompts several comments. Even slight (grade II) preoperative facial impairments increased the risk of severe postoperative facial dysfunction. Keratitis was frequent (42%) even in patients with normal facial function. Thrombo-embolic complications only occurred after long air-travel (≥5 h). Preoperative caloric test status was predictive of postoperative vestibular disturbance occurrence. With respect to the activity recovery; younger patients (<40 years old) displayed faster central compensations than the older (>60 years old) patients. This study highlights several features that may be used for preoperative patient counseling and complication management. In particular, the practitioner has to pay attention to even minor preoperative clinical signs of facial dysfunction to properly inform the patient of facial outcome. Routine ophthalmologic evaluation should be practiced, even when facial function is normal or subnormal. Level of evidence: 1b.
