Otitis externa malignant. A case report and review of literature.

Otitis externa malignant (OEM) is a virulent infection if it is not diagnosed and treated promptly. Its mortality rate was reported to be 53% when there is associated facial nerve paralysis. It usually affects elderly diabetic patients, who present with deep-seated pain and other features of non-resolving otitis externa. It is mostly caused by Pseudomonas (P) aeruginosa and the treatment of choice is anti-Pseudomonas antibiotic. A 64-year-old diabetic male patient is described who presented with left ear pain and discharge for two months and did not respond to ordinary treatment. The patient also noticed a progressive facial weakness on the same side. The clinical presentation, investigations, treatment and follow-up of the OEM are discussed on the basis of our case and the review of the literature. The diagnosis of OEM is based on high index of suspicion and confirmed by histopathologic changes and radionuclide studies. Gallium 67 citrate scan is a sensitive way to diagnose and follow up the regression of the disease in response to the medical treatment. Ciprofloxacin is the treatment of choice; however, it has to be in accordance to culture and sensitivity results.

Deep-neck space abscesses.

OBJECTIVE: Despite a reduction in the incidence, deep-neck space infections are still seen today with definite potential for significant morbidity and even mortality. DESIGN: The authors present their experience in the management of 16 patients with 19 deep-neck space abscesses. The distribution of the abscesses were: 5 Ludwig's angina, 4 parapharyngeal abscesses, 3 retropharyngeal abscesses, 3 in the sub-mandibular triangle, 3 in the deep anterior triangle, and 1 in the deep posterior triangle. RESULTS: The source of infection was odontogenic in six patients, pharyngeal in three, otogenic in one, and could not be identified in the other six patients. Most cases presented with pain and neck swelling. Plain x-ray films, computed tomography, ultrasonography, and magnetic resonance imaging were the main diagnostic procedures. Positive culture was obtained in only nine cases (56.2%). No predominant single organism was identified. Antimicrobial therapy and surgical drainage were the mainstay of treatment. Two cases were complicated by internal jugular-vein thrombophlebitis. All the patients survived without major residual sequelae. CONCLUSIONS: The etiology, presentation, and management of deep-neck space infections are briefly reviewed.
