Surgical Management of Parapharyngeal Space Tumors: Our Experience

Abstract

The purpose of this study is to evaluate parapharyngeal space (PPS) tumors with regards to clinico-pathological features and pre-operative assessment and also to analyze the benefits of transcervical approach in the management of PPS tumors. We performed retrospective analysis of patients who had undergone transcervical resection of PPS tumors from May 2006 to May 2009 at KLES Dr. Prabhakar Kore Hospital and M. R. C, Belgaum. Patients were diagnosed on the basis of clinical examination, FNAC and magnetic resonance imaging. All patients were observed with an annual follow-up of at least 3 years by physical examination and ultrasonographic evaluation. The total number of patients were four; with three males and one female patient. Their age varied from 20 to 55 years with a mean age of 36 years. There were two cases of neurilemomas, one case of carotid body tumor and one case of pleomorphic adenoma. All four patients underwent surgical excision of tumor by transcervical approach. There were no major post-operative complications. All four patients are alive with no recurrence in the 3 year follow-up period. Transcervical approach is versatile, flexible and provides good access to the narrow PPS. This approach also provides good vascular control and reduced risk of post-op complications. We recommend transcervical approach even for large sized pre-styloid and post-styloid compartment benign tumors which are free from deep lobe of parotid.
