the IC. The data clearly indicate the usefulness of Arg3.1/arc and BDNF for monitoring trauma-induced activity changes and the associated putative plasticity responses in the auditory system.
VIII Somatic tinnitus
Somatic modulation of tinnitus: test reliability and results after repetitive muscle contrac- tion training. Ann Otol Rhinol Laryngol. 2007 Jan;116(1):30-35.

Objectives: We sought to study the reliability of tinnitus modulation by muscle contractions and to obser- ve the effect of their prolonged repetition. Methods: Thirty-eight patients with tinnitus underwent 9 maneuvers of muscle contractions in test and retest situations. After a 2-month training period of repeating the maneuvers, tinnitus modulation and daily perception were evaluated. Results: There was no difference between the occurrence of tinnitus modulation in test (57.9%) and retest (63.2%) situations. After 2 months, the occurrence of modulation during the maneuvers was simi- lar (55.3%), but a new pattern showed an increase in tinnitus improvement and a decrease in tinnitus worsening. The daily perception of tinnitus was unchanged. Conclusions: Maneuvers of head and neck muscle contractions evoked tinnitus modulation in a fre- quent and reliable manner. Also, the repetition of such maneuvers for 2 months altered the pattern of modulation.

This work seeks to alert medical and odontological staff to understanding and using interdisciplinary handling for detecting different pathologies common otic symptoms. It offers better tools for this shared symptomatology during therapy s conservative phase. Tensor tympani muscle physiology and function in the middle ear have been veiled, even when their dysfunction and anatomical relationships may explain a group of confused otic symptoms during conventional clinical evaluation. Middle ear muscles share a common embryological and functional origin with chewing and facial muscles. This article emphasizes that these muscles share a functional neurological and anatomical dimension with the stomatognathic system; these muscles increased tonicity ceases to be a phenomenon having no logical connections. It offers functionality and importance in understanding referred otic symptoms in common with other extra- otical symptom pathologies. Tinnitus, vertigo, otic fullness sensation, hyperacusia, hypoacusia and otal- gia are not only primary hearing organ symptoms. They should be redefined and related to the neighbo- ring pathologies which can produce them. There is a need to understand temporomandibular disorders and craniofacial referred symptomatology from neurophysiologic and muscle-skeletal angles contained in the stomatognathic system. Common symptomatology is frequently observed in otic symptoms and temporomandibular disorders during daily practice; this should be understood by each discipline from a broad, anatomical and clinical perspective.
