Background and Objectives : Parapharyngeal infections are rare but they cause life-threatening complications such as mediastinitis, rupture or aneurysm of the internal carotid artery, internal jugular vein thrombophlebitis. so, until now, the recommended treatment of parapharyngeal abscess is early open surgical drainage. The purpose of this study is to review the clinical course and outcome of treatment in parapharyngeal abscess according to method of treatment. Materials and Method : A retrospective study was performed on 34 cases with parapharyngeal abscess in patients admitted for deep neck infection during a 8-year period from June 1994 to January 2003. All had contrast-enhanced computed tomography (CT) imaging and had cofirmation of an abscess in parapharyngeal space. Results : All patients were treated with intravenous antibiotics, 19 cases ( conservative group) were treated with antibiotics only or needle aspiration, 15 cases (surgical group) were treated with intraoral or external drainage. The mean period of hospitalization was 8.2 days in conservative group and 11.6 days in surgical group. There was no complication except the mediastinitis in one case of conservative group. Five patients required tracheotomy because of severe dyspnea. Conclusion : Neck CT scan is useful diagnostic tool to detect and establish treatment plan of parapharyngeal abscess. Parapharyngeal abscess may, in some cases, respond to antibiotics, become localized to parapharyngeal space and treated conservatively with no need for early open surgical drainage.
