The issue of cochlear implantation in deaf children with associated disabilities is an emerging subject. Currently, there is no consensus on whether to implant children with multiple impairments; moreover, it may be difficult to evaluate these children with standard tests pre- or post-implantation. In addition, these children often have poor speech perception and language skills, making assessment more difficult. Despite these factors, these children often receive important benefits in daily life, with an overall improvement in quality of life. In the present study, post-implant outcomes of 23 profoundly deaf children with neuropsychiatric disorders were analysed, using objective measures of speech perception, and a questionnaire administered to the parents, aimed at evaluating the benefits in daily life after implantation. The results were quite variable, but overall positive, in terms of speech perception, communication abilities, and improvement in quality of life. The findings add an additional piece of evidence to support the effectiveness of cochlear implantation in these special cases.

The outcome of cochlear implantation in patients with deafness of prelingual onset is largely unpredictable due to high individual variability. This study evaluated speech perception performances in a group of 18 prelingually deafened subjects (aged 13–30 years) which was homogeneous with respect to duration of deafness, hearing aid use before cochlear implantation, mode of communication and administration of auditory-oral speech therapy. Word discrimination length, word and sentence identification, phoneme identification and word and sentence recognition were tested before cochlear implantation and at 6 months, 1, 2 and 3 years of cochlear implant use. Scores on all tests significantly improved after cochlear implantation, although mean values were lower compared to those achieved by postlingually deafened patients. Speech performances on both word and sentence recognition continued to increase over time also beyond 1 year after cochlear implantation. Moreover, scores on sentence recognition tests were significantly higher compared to disyllabic words at 3 years of cochlear implant use. The presence of an auditory input delivered by hearing aids before cochlear implantation associated with auditory-oral therapy and a good level of education may positively influence the cochlear implant outcome in prelingually deafened adults.

A selective epitympanic dysventilation syndrome is hypothesized; normal ET function seems to be insufficient for complete ventilation of the middle ear, and an open tympanic isthmus or an incomplete tensor fold may be necessary for epitympanic recess ventilation. The selective epitympanic dysventilation syndrome would consist of the contemporary presence of the following four conditions: attic retraction pocket or cholesteatoma, normal tubal function tests, complete epitympanic diaphragm, and isthmus blockage.

Three main types of endoscopic tympanoplasty can be performed for surgical treatment of attic retraction pockets, preserving as much as possible the ventilation routes, physiology, and anatomy of the middle ear.
