Porém, qualquer região que apresente cobertura pelas leptomeninges é potencialmente um sítio de origem para este tumor. O primeiro relato de um ME exclusivamente intracranalicular (IC) é atribuído a Singh et al. em 1975. Desde então, aproximadamente 15 MEIC se encontram descritos na literatura de língua inglesa.

The use of hearing aids (HA) is not possible in cases in which agenesis or stenosis of the EAC accompanies conductive deafness. In contrast, bone conduction implants such as the Bone Anchored Hearing Aid (BAHA(®)) allow direct stimulation of the cochlea and are thus superior to conventional hearing aids in cases of severe conductive hearing loss. To present 2 cases of patients with Treacher-Collins syndrome who underwent implantation of BAHA(®). The first patient was a 52-year-old woman diagnosed with Treacher-Collins syndrome who presented with severe bilateral mixed hearing loss and a history of unsuccessful previous use of a bone contact conduction device. The BAHA(®) implantation was uneventful, and the post-operative results were good. The second patient was a 14-year-old girl who was also diagnosed with Treacher-Collins Syndrome with bilateral moderate conductive hearing loss by audiometry. The use of a bone vibrator contact device did not improve her hearing; however, implantation of a BAHA(®) resulted in a decreased gap postoperatively. Final comments: BAHA(®) hearing devices provide adequate rehabilitation and consequent improvement of the quality of life in patients with Treacher-Collins syndrome.

Objetivo: Demonstrar, através da dissecção com técnicas microcirúrgicas, as estruturas anatômicas do osso temporal do primata Callithrix sp. Forma de estudo: Experimental. Método: Dissecção de ossos temporais de Callithrix sp e documentação fotográfica. Resultados: Identificamos as principais estruturas do osso temporal (orelhas externa, média e interna, e nervo facial). Conclusão: O primata não-humano Callithrix sp representa aparentemente um modelo viável para o estudo do osso temporal uma vez que apresenta alta similaridade anatômica com humanos.

To demonstrate, by means of micro dissection techniques, the anatomical structures of temporal bones from the primate Callithrix sp. Experimental. Dissection of temporal bone structures of Callithrix sp and photographic documentation. We identified the main constituents of the temporal bone (external, medium and inner ear and facial nerve). The non-human primate Callithrix sp. is an adequate experimental model for the studies of temporal bone structures given its close anatomical similarities to that found in humans.

Acupuncture is recommended for the relief of tinnitus in traditional Chinese Medicine, although scientific evidence is lacking. The aim of this study was to assess the effect of acupuncture on the cochlear function in patients with tinnitus by analyzing otoacoustic emissions. Thirty eight patients with tinnitus were included in the prospective clinical study. Measures of transitory otoacoustic emissions and suppression of otoacoustic emissions were obtained from all subjects before and after acupuncture. Patients were assigned to one of two groups: intervention group 1 (n=19), in which needle acupuncture was applied at the temporoparietal point corresponding to the vestibulocochlear area, and intervention group 2 (n=19), in which the needle was applied 3 cm cranially to this area (which is not a recognized acupuncture point). There was a significant difference between the amplitude of otoacoustic emissions assessed before and after acu...
