Practice Essentials Malignant Otitis Externa-MRI. Toulmouche was probably the first physician to report a case of malignant external otitis (MEO), in 1838. Meltzer reported a case of pseudomonal osteomyelitis of the temporal bone. In 1968, Chandler discussed the clinical characteristics of malignant external otitis (MEO) and defined it as a distinct clinical disease.

Acute Otitis Media: Part I. Improving Diagnostic Accuracy Nevertheless, the medical literature suggests that acute otitis media is frequently over-diagnosed. Good otoscopic illumination, cerumen removal and attention to the position and mobility of the tympanic membrane (rather than only to the color) are important for an accurate diagnosis.

Cholesteatoma Hearing and balance tests, and CT scans (3-D x-rays) of the mastoid may be necessary. These tests are performed to determine the hearing level in the ear and the extent of destruction the cholesteatoma has caused. Surgery is performed under general anesthesia in most cases. The primary purpose of surgery is to remove the cholesteotoma to eliminate the infection and create a dry ear.

Myringotomy and Tympanostomy Tube Most cases of otitis media with effusion resolve spontaneously within 3 months of onset. An alternative to myringotomy with tube placement is a new tympanostomy procedure by CO2 laser without ventilation tubes, (also called tympanolaserostomy or laser-assisted tympanostomy [LAT]).

- Some patients may be referred for evaluation after the discovery of radiologic disease on a screening CT scan. These screening sinus CT scans often only include thicker (5-10 mm) axial cross sections of the paranasal sinuses. They can help to establish disease diagnosis in a more cost-effective manner.
