Two standard operative procedures have been either releasing the plantar fascia or removing the spur with drilling of the calcaneus.

Predictors of Preoperative Tinnitus in Unilateral Sporadic Vestibular Schwannoma.

Objective: Nearly two-thirds of patients with vestibular schwannoma (VS) are reporting a significantly impaired quality of life due to tinnitus. VS-associated tinnitus is attributed to an anatomical and physiological damage of the hearing nerve by displacing growth of the tumor. In contrast, the current pathophysiological concept of non-VS tinnitus hypothesizes a maladaptive neuroplasticity of the central nervous system to a (hidden) hearing impairment resulting in a subjective misperception.
