Dr Kana works with audiology and speech therapy colleagues, so that hearing assessment, surgery and postoperative audiological care are coordinated.
Chronic otitis media and cholesteatoma
A persistent perforation of the eardrum or a chronically discharging ear may indicate chronic otitis media. Cholesteatoma is an abnormal growth of skin within the middle ear that can gradually erode surrounding bone, including the hearing bones.
Surgery aims first to create a safe, dry ear and, where possible, to restore hearing. Planning is guided by otomicroscopy, audiometry and CT of the temporal bone.
Conductive hearing loss
Conditions such as otosclerosis or disruption of the ossicular chain can reduce the transmission of sound to the inner ear. Surgical options include stapes surgery and ossicular reconstruction. Hearing aids and implantable devices are appropriate alternatives for some patients.
Paediatric ear care
Recurrent acute otitis media and persistent middle ear effusion in children can affect hearing during an important period of speech and language development. Paediatric ear care, including ventilation tube (grommet) insertion, is provided at Netcare Mulbarton Hospital in Johannesburg South.
Integrated audiological care
Pre- and postoperative audiological testing, hearing-aid fitting and vestibular (balance) assessment are coordinated with audiology colleagues. This supports continuity from diagnosis through surgery to rehabilitation.
