To investigate the influence of middle ear effusion (MEE) on perilymph (PL), an experimental otitis media with effusion (OME) was manufactured in chinchillas by injecting the tympanic cavity with immune complexes. The presence of MEE lasted for up to 9 days after the injection of immune complexes. Perilymph was aspirated on the fourth, tenth, and 21st days after the inoculation. The mean concentrations of albumin, immunoglobulin G, histamine, and prostaglandin E2 (PGE2) were significantly greater in PL from ears with induced OME than in that from normal control ears. The 3H-PGE2 placed on the round window membrane of pathologically affected ears passed into PL in significantly greater amounts than in normal control ears. The findings indicate that the immune complexes placed in the middle ear cavity affect the biochemical milieu of PL, and that MEE is a result of immune complexes.

<p class="abstract"><strong>Background:</strong> Cochlear implantation (CI) has revolutionized the treatment of sensorineural deafness. The aim of the study was to compare auditory based performance in cochlear implants who underwent round window insertion and cochleostomy.</p><p class="abstract"><strong>Methods:</strong> Ambispective cohort study was done among the children who underwent perilingual cochlear implant in a tertiary care hospital for period of 1 year. Children who satisfied the inclusion criteria were selected and randomly subdivided into 2 groups: group A- round window insertion and group B-cochleostomy. Pre- and post-operative pure tone average (PTA) and residual hearing preserved were evaluated among the cochleostomy and round window insertion groups separately. Post-operatively, children were evaluated, from three months to 1 year from the activation of cochlear implant, with the use of scores such as Category of Auditory Performance (CAP), Meaningful Auditory Integration Scale (MAIS), Speech Intelligibility rating (SIR) and Meaningful use of speech scale (MUSS score) to measure speech production skills by auditory verbal therapist.   </p><p class="abstract"><strong>Results:</strong> A total of 80 patients were included in the study. Complete hearing preservation (within 10 dB) was significantly high in round window insertion group compared to   cochleostomy technique (p&lt;0.001). None the subjects had complete loss of residual hearing. On evaluating the post CI performance, MAIS score in the round window insertion group (9.34, 18.21, 27.79) were significantly better compared to cochleostomy group during the 3 months, 6 months and 12 months follow-up.</p><p class="abstract"><strong>Conclusions:</strong> Round window insertion technique is significantly more successful in complete hearing preservation at low frequencies compared to cochleostomy technique. Among the auditory scores, only MAIS in the round window insertion group was found to be significantly better compared to cochleostomy group.</p>

AbstractObjective:This study evaluated the complications and outcomes of cochlear implantation in patients who had otitis media with effusion at the time of surgery.Methods:A retrospective chart review study was performed of 87 consecutive paediatric patients (age range 22 months to 10 years, mean 4.8 years) who underwent successful cochlear implantation, with follow-up periods of 5–6 years. All patients had unilateral implants, with eight on the left side. All devices were activated two weeks after implantation. The effect of the middle-ear condition on the procedure, post-operative complications and outcome were evaluated.Results:Unilateral ears of 17 otitis media with effusion patients were implanted with some surgical difficulties but no long-term post-operative complications.Conclusion:For children admitted for cochlear implantation who are subsequently found to have otitis media with effusion, surgeons should be aware of possible surgical difficulties. Greater intra-operative risks should be anticipated and more surgical time allowed for cochlear implantation in these patients.
