Abstract

The tumors of parapharyngeal space constitute only 0.5% of all head and neck tumors. The majority (over 80%) of the primary parapharyngeal space tumors arising from pre and poststyloid space are benign. Main structures contained in the prestyloid space are fat, deep lobe of parotid gland and minor or aberrant salivary glands of the oropharyngeal wall. Unlike the poststyloid space, this space does not have important vital neuro-vascular structures, but it is difficult to approach it. In the surgery of poststyloid tumors, the most important problem is to protect vital structures from being injured. A number of surgical approaches have been described to overcome these difficulties. Transcervical approach is the main access to the parapharyngeal space. However, additional combinations of this approach with or without mandibulotomy are mostly applied for wider exposure of the bulging oropharyngeal mass. Our experience proved that the transoral-transcervical dual approaches are the least morbid combination for a wider access. It should be emphasized that this approach is much easier and safer than the other combined approaches. Mandibulotomy must be performed only for malignant tumors that infiltrated the skull base.
