Abstract
BACKGROUND: The parapharyngeal space, situated in the neck's lateral part, poses challenges for surgical intervention due to its complex anatomy. Tumors in this space are rare, accounting for 0.5-1% of head and neck tumors, often remaining asymptomatic until reaching substantial sizes. MATERIAL AND METHODS: This article outlines the surgical management of such lesions using navigation software, illustrated through a clinical case. A 38-year-old male presented with a mass at the right mandibular angle. Preoperative planning with Brainlab iPlan CMF® software aided in understanding the tumor's relationship with adjacent structures. A transcervical approach facilitated tumor excision without damaging vital anatomical structures. Histopathology confirmed pleomorphic adenoma. RESULTS: The paper underscores the rarity of parapharyngeal tumors, the importance of individualized surgical strategies, and the utility of 3D technology in preoperative planning for enhanced anatomical understanding. CONCLUSIONS: The cervical approach remains a satisfactory choice for benign lesions in this challenging space.
