A case of a 44 year-old woman farmer with a total deafness and lack of vestibular function on the left side operated upon the cerebello-pontine cystic neuroma 2.5x2.0x1.5 cm large via the retromastoidal craniectomy is presented. Despite of the negative audiological tests' results the cochlear nerve flatten on the tumor was cautiously separated. Some time after surgery, she observed "a partial recovery of hearing" in the operated ear confirmed by the tonal (mean 0.5-2 kHz 36 dBHL) vocal SRT 70 dB), BERA and EOAEs tests. The paralysis of the left vestibular function did not recover. In consecutive audiogram a notch at 6 kHz 15 dB deep appeared in the operated ear and one can presume an increased vulnerability of this ear to the noise of the agricultural machines used by then by the patient.
