Delayed spontaneous return of hearing after acoustic tumor surgery: Evidence for cochlear nerve conduction block†
Laryngoscope, 1990Co-Authors: John F. KvetonAbstract:Unlike the eventual resolution of facial paralysis in most patients with intact facial nerves, delayed hearing return after acoustic tumor resection is rare. This discrepancy in recovery has been ascribed to the inherent resilience of the facial nerve (a Special visceral efferent nerve) to injury versus the cochlear nerve (a Special Somatic Afferent nerve). In the presence of an intact cochlear nerve, hearing loss has been attributed to transection or spasm of the internal auditory artery or to direct mechanical trauma to the cochlear nerve during manipulation of the tumor. The possibility of a reversible conduction block in the cochlear nerve has not been considered. A review of three instances of delayed spontaneous hearing recovery several months after acoustic tumor resection suggests that a conduction block phenomenon can exist. This report describes the patho-physiology and the possible intraoperative predisposing features of this condition.

Sensory System
Mayo Clinic Medical Neurosciences, 2017Co-Authors: Eduardo E. Benarroch, Jeremy K. Cutsforth-gregory, Kelly D. FlemmingAbstract:The sensory system provides information to the central nervous system about the external world (exteroceptive) and the internal environment (interoceptive). Impulses traveling toward the central nervous system are called Afferent impulses. Afferent information may be transmitted as conscious data that are perceived by the organism and then used to modify behavior; as unconscious data that, although used to modify behavior, remain unperceived by the organism; or as both conscious and unconscious data. Afferent impulses are functionally subdivided into 4 categories: general Somatic Afferent impulses (from skin, striated muscles, and joints), general visceral Afferent impulses (largely unconscious, from serosal and mucosal surfaces, smooth muscle of the viscera, and baroreceptors), Special Somatic Afferent impulses (relating to vision, hearing, and equilibrium), and Special visceral Afferent impulses (relating to taste and smell).

Auditory and Vestibular Systems
Noback's Human Nervous System Seventh Edition, 2012Co-Authors: Norman L. Strominger, Robert J. Demarest, Lois B. LaemleAbstract:The auditory and vestibular systems often are considered together because their end organs share space within the petrous portion of the temporal bone (Fig. 16.1) and both arise from the otic vesicle. They also share the VIIIth cranial nerve, albeit the two almost completely separate divisions, auditory and vestibular classified as Special Somatic Afferent. However, the auditory system is exteroceptive, whose purpose is to transduce airborne waves in the acoustic spectrum and most importantly deliver signals to higher centers of the auditory system for perception of sounds. The vestibular system in contrast is proprioceptive. Its receptors monitor head position and movement and convey this information into the brain stem, where it is integrated into the motor systems. The vestibular system is important for maintaining equilibrium and upright posture and for control of synergistic eye movements.
