Methods Of Treatment

Malignant external otitis is an infection which begins in the external auditory canal. It is uniformly caused by the Gram negative Pseudomonas aeruginosa organism and mainly affects elderly diabetics. It spreads to the soft tissues beneath the temporal bone and, if not properly treated leads to facial nerve palsy, mastoiditis, sepsis, osteomyelitis of the base of the skull, sigmoid sinus thrombosis, multiple cranial nerve palsies and death. Experience with 72 patients in varying stages of the disease is summarized. Stressed are the diagnostic criteria of nonresponsiveness to the usual methods of treatment, continued suppuration, and the continuing reformation of granulation tissue in the floor of the external auditory canal. Medical treatment is recommended with hospitalization and intravenous carbenicillin and gentamicin. Minor surgical debridement is helpful. All patients should be treated medically for as long as improvement continues, reserving surgical intervention only in the event a plateau is reached or symptoms and signs become worse under treatment. With or without a major surgical procedure, it is imperative to continue treatment for at least seven days after apparent cure in order to avoid recurrent disease possibly at a site distant from the canal.

Conductive Hearing

External auditory canal exostosis (EACE) is prone to occur in patients frequently exposed to cold water, which causes earwax impaction, recurrent otitis externa, and conductive hearing loss. The main treatment for symptomatic EACE is surgical excision. External auditory canal cholesteatoma (EACC) is a bone-destructive cystic mass caused by accumulation of plugs of desquamated keratin debris in the external auditory canal (EAC), which is also mainly treated with surgical removal. The main difficulties in the surgical removal of obstructive EACEs or EACCs are related to the adjacency of EAC skin, tympanic membrane, temporomandibular joint, and the blockage of the medial EAC landmarks during the operation. The piezoelectric device (PZD), which has long been used to cut bony structures in dental surgery, has clinical advantages here with regards to accurate exclusive bone cutting ability and minimal heat production. We report a series of cases that managed EAC lesions using PZD.

External Auditory Canal Cholesteatoma

Three patients with extensive keratosis obturans were treated during a 12-month period. One presented with an idiopathic sensorineural hearing loss and was found to have keratosis obturans in the contralateral, asymptomatic ear. The disease process had resulted in a horizontal semicircular canal fistula in what was now, effectively, the only hearing ear. The second patient had an extensive dehiscence of the tegmen tympani. The third presented with a facial palsy. An automastoidectomy cavity was present, with circumferential skeletonization of the descending facial nerve over a length of 1.5 cm and dehiscence of the temporomandibular joint and jugular bulb. All three patients were successfully treated by surgical formalization of their automastoidectomy cavities. They appeared to represent cases of keratosis obturans rather than external auditory canal cholesteatoma, on the basis of previously published reports.These complications and patterns of bone erosion have not previously been described in keratosis obturans. The third patient is believed to have the most extensive case of keratosis obturans yet described.
