Induced Changes

Many studies have shown that antihistamines and decongestants are of little use in the treatment of acute otitis media and otitis media with effusion, or in the prophylaxis of these disorders.1 However, because some drugs can improve otitis media with effusion (glycocorticosteroids)2–4 and some can impair the opening function of the eustachian tube (atropine),5 it seems justified to continue studies of eustachian tube function and medication.

The Relationship

The relationship of eustachian tube surfactant and otitis media with effusion on eustachian tube opening pressure was studied in a gerbil model. Injection of killed Streptococcus pneumoniae bacteria created a serous effusion that increased eustachian tube opening pressure. The introduction of exogenous surfactant to this system resulted in a dramatic decrease in eustachian tube opening pressure in both normal ears and those with effusion. Identifying means to increase surfactant in the eustachian tube could be beneficial in reducing persistent otitis media with effusion.

Tube Function

Prolonged observations of the eustachian tube (ET) function were made on 40 ears of 20 patients with nasopharyngeal carcinoma (NPC) who survived more than 5 years after radiotherapy in a state of remission. The ET function tests included passive opening, inflation-deflation, and clearance, and were performed before, at 6 months, and at 5 years after radiotherapy. The test results were found to be worst at 6 months after radiotherapy and improved at 5 years after radiotherapy. Tubal obstruction and inflammation are the main causes of the ET malfunction that results in otitis media with effusion (OME) in NPC patients after radiotherapy. Insertion of a ventilation tube into the ear with OME can relieve tubal obstruction but can aggravate inflammation. Thus, myringotomy and aspiration of effusion and local treatment may be preferable to insertion of a ventilation tube in NPC patients with OME. When hearing improvement in prolonged survival of NPC patients with OME is needed, the use of amplification is recommended.

Experimentally Induced

Exogenous surfactant can improve eustachian tube function in experimentally induced otitis media with effusion (OME). Performing tympanometric recordings, the efficacy of inhaled nebulized surfactant, as compared with inhaled nebulized physiological saline was investigated, for the treatment of OME experimentally induced in the rabbit by intrabullar inoculation of heat-killed Streptococcus pneumoniae. In addition, the histological changes in middle ears after the treatment were investigated in order to establish whether the pathological findings correlated with the results.Middle-ear pressure values before, and after, treatment were analyzed by the Wilcoxon statistical method, and the Mann-Whitney U test was used to compare the post-treatment values between groups. In all ears with OME in the affected animals, which were treated with nebulized surfactant inhalation, a positively significant (p<0.05) increase of pressure more than 20 daPa was recorded. In the control group, after inhalation of nebulized physiological saline, there was no positive increase in the affected middle-ear pressures; on the contrary, more negative pressure changes were recorded. In the histological evaluation, middle-ear epithelia and sub-epithelial space were normal in surfactant-treated ears with OME, whereas mucosal thickening with an oedematous sub-epithelial space containing occasional inflammatory cells and increases in connective tissue and vascularity, and effusions on the epithelial surface were present in the ears with OME in the control group. The significant improvement in the negative middle-ear pressure after nebulized surfactant treatment and the histological findings shown in our study can support the theory that surface-active agents are of importance in eustachian tube function even under pathologic conditions, such as OME.
