“…Yet, there are still some cases of recurrence. Morphological studies in the past indicate that remaining sensory epithelia, nerve regeneration and neuroma formation are responsible for recurrence [1][2][3]. However, studies about how behavior or static posture changes after regeneration of the nerve of the sensory cell are scarce.…”

Sectioning of the unilateral vestibular nerve of the bull frog resulted in tilting of the head and the body. The angle of head tilt was periodically measured. The angle returned to 0° in an average of 7.3 weeks. A morphological study demonstrated normal structure of the sensory epithelia and a well-regenerated nerve bundle. Also, discrete action potentials could be recorded from the nerve centrally to the cut site of the vestibular nerve. These results indicate that recovery from the tilting involves two mechanisms, one being central compensation and the other reactivation of the sensory cell-nerve unit.

“…It is indicated in cases of Meniere's disease when useful hearing remains in the affected ear, and when medical management and hearing preserving surgical procedures, such as saccus decompression, have proved ineffective. It may also be indicated if, following attempted surgical destruction of a labyrinth, persisting symptoms suggest residual functioning end organ neuroepithelium, or vestibular stump neuroma (Ludman 1986). Follow-up data of patients who have undergone VNS (Barber and Ireland, 1952;Green, 1958;Kemink and Hoff, 1986) have generally concentrated upon assessment of symptomatic relief of vestibular symptoms and residual cochlear function.…”

Unilateral vestibular nerve section (VNS) creates a state of acute dysequlibrium which resolves by a process of central compensation. This disturbance resolves quickly and central compensation is complete generally within a month with resolution of symptoms and signs. The course of central compensation following VNS will be similar to that seen after labyrinthectomy because the detachment of hemi-labyrinthine input that is achieved by both will be identical. Six patients are presented who have undergone VNS at least 2.7 years ago (Average 3.5 years); all of them have persisting spontaneous peripheral type horizontal jerk nystagmus, present with optic fixation in five. This is obvious clinically and was confirmed in each case by agreement of three independent observers and has been recorded by electronystagmography (ENG). They are free from marked vestibular symptoms. The explanations of mechanisms involved in central compensation are discussed with respect to this previously unrecorded clinical observation.
