Semiologia Hearing

The development of the fabric to glandular is bigger in the after-Christmas period, diminishing acentuadamente with the growth of YOU To Another important factor is the supina position, that increases the possibility of refluxo and this form the incidence of average otitis in children. d? Physiology and Pathology: it has YOU 3 main functions in relation to the average ear: 1.Proteo against secretion and gradient of pressure of nasofaringe; 2.Drenagem and clearance of secretion of the average ear for nasofaringe; 3.Ventilao of the average ear for equalizao of its pressure with atmospheric pressure. Physiological ideal Tuba = active and intermittent opening (contraction of the MTVP during the deglutition and yawn), keeping the pressure of the average ear next to the one to the environment. e? Imunolgicos factors: – Secretor immune System of the mucosa of the similar average ear to the mucosa of the remain of the respiratory treatment. – Allergy: the influence of the allergy in the etiology of the average otitis comes being studied.

The alrgica reply at least it premakes use the patient to the effusion of the average ear, since cause congestion and blockage of tuba auditory. Internal ear or Labyrinth is formed by neuroepiteliais structures (ciliadas cells, cells of sustentation and gelatinous membrane), membranoso labyrinth (ductos filled for endolinfa) and sseo labyrinth. The cclea is responsible for the semicircular hearing, and vestibule and canals for the balance. Physiology the sound is a vibratory energy that penetrates in the MOTHER and happens in TM, being transmitted to the ossculos. This sonorous vibration is translated into electric energy in the internal ear, that is sent to the central nervous system with all its characteristics of intensity, frequency and harmony, reaching the brain in previous the secular turn transverso, when the sound is recognized. Semiologia of physical the Semiologia Hearing: inspection; palpao; otoscopia; examination of tuba auditory (air insufflation? Valsalva, Politzer and radiological sounding lead of Itard), cateterismo, examinations (simple x-ray, computerized cat scan and magnetic nuclear resonance).
