The most common presentation was an intraoral mass (52%) followed by a cervical mass (48%), and the most common primary lesion was a pleomorphic adenoma (29%). Ninety‐six percent of patients underwent surgery. The cervical approach was most frequently used (46%), and the most common complication was vagus nerve injury (13%). Within our institution, 5‐year progression‐free survival for benign and malignant disease was 93% and 61%, respectively (<italic>P</italic> = .196).</p> </sec> <sec id="lary25077-sec-0005" sec-type="section"> <title>Conclusions</title> <p>A parapharyngeal space mass is an uncommon tumor and requires careful preoperative assessment.
