ABSTRACT
This is a report of seven patients with various degrees of stridor and airway obstruction due to redundancy of the aryepiglottic folds. This condition appears to be acquired and is most likely caused by central nervous system pathology which disrupts the normal neuromuscular function of the larynx.

We present an unusual case of bilateral temporal bone destruction due to eosinophilic granuloma in a young child. The patient initially presented with otitis media, with subsequent rapidly developing bilaterally symmetric masses in the mastoid region. Computed tomography demonstrated extensive bony destruction which, after a course of vinblastine chemotherapy, improved dramatically on follow-up scans.

Focused ultrasound was applied at the lateral semicircular canal in 19 patients and at the round window in 12 patients, all of whom had intractable vertigo caused by Meniere's disease. Postoperatively, the vertigo was relieved or diminished in 75% of the lateral canal cases and in 25% of the round window cases. The results indicate that the lateral canal approach may have some therapeutic value, but the treatment is arduous for the patient and the risk of facial palsy is always nettlesome. Utilizing similar techniques, ultrasound irradiation was given to the lateral canals of 6 squirrel monkeys and to the round windows of 15 cats. After survival times of up to 3 months, light microscopic studies of the temporal bones of these animals show no morphological changes which can be attributed to the ultrasound irradiation. In general, these findings are in concert with the reports of other investigators and show that selective ablation of the vestibular sense organs cannot be achieved by current techniques of ultrasound irradiation. It seems doubtful that prolonged relief of vertigo can be expected to occur without a more complete morphological ablation of the vestibular sense organs than is possible with the current methods of ultrasound treatment.

Congenital (primary) cholesteatomata may arise in the petrous apex, mastoid, middle ear, or external auditory canal. Histological studies of the temporal bones of a 20-year old man with bilateral combined deafness show bilateral congenital cholesteatomata of the middle ears associated with dalivary choristomata and other anomalies of the middle and inner ears.
