Key inclusion & exclusion criteria

Patients meeting the diagnostic criteria for von Hippel-Lindau (VHL) disease.

No persons who are pregnant or lactating are eligible for the surgical arm of this
protocol until the pregnancy and/or nursing period has reached completion.

No patients with disorders associated with multiple abnormalities of the middle ear and
inner ear. Specific laboratory abnormalities such as anti-HIV-1, FTA-Abs, serum ANA, and
ANCA have been associated with AIDS, Syphilis, Systemic Lupus Erythematosus, and Wegener's
Granulomatosis, respectively.

No patients currently undergoing chemotherapeutic regimen with ototoxic agents (e.g.,
cisplatin). Other agents will be reviewed on a case-by-case basis for their potential to
cause ototoxicity and thereby interfere with audiologic data interpretation.

Patients with an ELST in an only hearing ear will be excluded from the protocol for
surgical treatment of ELST's (except in cases where other medical indications necessitate
intervention for the welfare of the patient).

Patients with only unilateral vestibular function on the side affected by the ELST, as
documented by caloric ENG testing, will be excluded from the surgical treatment group in
most cases.

No patients with the inability to understand all of the requirements of the study or
inability to give informed consent and/or comply with all aspects of the evaluation.
