IS THE VESTIBULAR SYSTEM AFFECTED BY MIDDLE-EAR EFFUSION

The association between middle ear effusion (MEE) and vestibular pathology is controversial. To investigate this point, 50 children with MEE scheduled for myringotomy and grommet, and 20 normal hearing children without MEE scheduled for adenotonsillectomy, underwent vestibular investigations by craniocorpography and rotatory chair, preoperatively and postoperatively. Most of the correlations, preoperative vs. postoperative, and study vs. control groups, were nonsignificant. Assuming that serous labyrinthitis is responsible for vestibular involvement in MEE, the lack of significant vestibular pathology in our study could probably be explained by the fact that no children with acute otitis media episodes or otalgic were included.
