Acute parapharyngeal space infections. A report of 12 cases

Parapharyngeal space infections are a serious condition with a significant morbidity and mortality. Twelve cases seen between 1987 and 1990 are described. From the clinical findings it was clear that the tonsils appeared to be the most common source of infection and not other aetiological factors, such as dental and salivary gland pathology. Computed tomography was excellent in delineating the mass, but if this is not available ultrasonography appears to be of benefit. Intravenous antibiotics and the appropriate surgical intervention, when indicated, is the treatment of choice. An excellent clinical response was experienced; however, in 25% of patients recovery was complicated by aspiration pneumonia.
