Mise au point sur les oto emissions acoustiques [OEA]

Oto-acoustic emission are sounds emitted by the cochlea as a response to a stimulus probably based upon contraction characteristics of the outer hair cells. We are end ebbed to D.T. KEMP who discovered and applied this clinical examination. In 1978, he showed that the cochlea is able to emit sounds either spontaneously or as a response to a stimulus. This examination is simple, quick, non-traumatic, objective and allowing a net examination of the cochlea function. The clinical interest of this examination is unanimous in children mainly in the detection of deafness

Lacervicotomie a visee diagnostic bilan de 320 cervicotomies 1983-1987

In a study of 320 cases of cervicotomy carried out in the ORL department in the specialised hospital in Rabat, we have tried to show the importance of this operation in the setting-up of a sure diagnosis based on an anatomo-pathological study. So, cervicotomy has given a sure diagnosis in 65%, has corrected the presumed diagnosis in 10%, Has confirmed the presumed diagnosis in 25% we have a global efficiency of 75%. The etiology of chronic cervical tumefactions are varied, but they remain predominated by ganglion tuberculosis, however they may reveal a blood disease or unknown cancer
