The Research and Appraisal about the Resection Method of Primary Huge Parapharyngeal Space Neoplasmsthrough the Lateral Entrance of Jaw-neck Joint

According to four cases of resection of primary huge parapharyngeal space neoplasms through the lateral entrace of jaw-neck joint and removal of ramus of mandible, we detailedly introduce the anatomic particularity of parapharyngeal space, the clinical characteristics, the diagnostic methods and the concrete operative steps of primary parapharyngeal space neoplasms And we also overall analyse the advantages and disadvantages about this operative entrance and expound some problems which should be noted in the operation We consider that this operative entrance exposes the field of the operation well and is easy to handle; the operative method is easy to be changed during the operation; the functional disorder in the post-operation is light; this approach is especially suited to resect huge paraphanyngeal space neoplasms
