A 45-year-old male patient with reduced hearing in the right ear was diagnosed with
a medium-sized (T3a) acoustic neuroma. The operation was performed through an individually
tailored retrosigmoid mini-craniotomy. Endoscope-assisted microsurgical technique
was applied to early detect the location of the facial and cochlear nerves as well
as to look around the hidden corners during the surgery. The entire operation was
performed without using brain retractors. The moderate intrameatal extension of the
tumor and the use of angled endoscopes allowed to avoid the drilling of the internal
auditory meatus. The lesion could be completely removed and the patient showed a satisfactory
hearing recovery in the follow-up examinations 3 months after the surgery.
