We have studied the temporal bones of 4 deceased donors, individuals one with cochlear saccular degeneration, another with Mondini dysplasia, another with an ossification of the basal turn of the cochlea and the round window, post meningitis and the fourth who was implanted 10 years before. The indications and contraindications for cochlear implant placement are discussed.

Recurrent bacterial meningitis is not a common disease and makes physicians seek underlying predisposing factors which can result from anatomic anomalies or immunodeficiency. In this paper we present a boy with recurrent bacterial meningitis with the history of trauma and sensorineural hearing loss. Mondini dysplasia was demonstrated with computed homographic scans (CT-Scan) of temporal bones.

The scientific report written in Latin by Carlo Mondini in 1791, titled The Anatomic Section of a Boy Born Deaf (1), has been often cited but seldom read. Recently, the American Journal of Otology published an English translation by Gordon J. Hartley of Rugby, England, with comments by Peter D. Phelps (2). Originals of Mondini’s publication known to exist in the United States are in the collect...

Mondini dysplasia is a congenital malformation of the inner ear, which is characterized by a short and large cochlear canal of 1.5 turn rather than 2.5 turns and an apical region with cystic dilatation. Patients present with congenital deafness, when both cochlea are affected. Unilateral disease may cause recurrent meningitis, otorrhea or rhinorrhea. In this article, we report a three-year-old ...
