Abstract
Parapharyngeal space tumors account for about 0.5% of all head and neck cancers; the majority of these rare tumors (about 80%) are benign (1). The most frequent parapharyngeal space tumor originates in salivary glands and the pleomorphic adenoma represents the most common histological type. Generally, most tumors originating from the retro-styloid space are neurogenic, while tumors coming from salivary glands usually fill the pre-styloid space. We present a case report of combined cervical trans-parotid and intraoral access in patient with double neoplasms, starting from superficial and deep parotid spreading in the parapharyngeal space. After superficial parotid neoformation removal through a pre-tragal preauricular approach, we performed an intraoral incision laterally to the left tonsil pillar. We detached the neoformation with its capsule, showing no neurovascular structure placed anteriorly to the neoplasm. Through intraoral approach, thus, it is possible to access to MPS in safety, avoiding excessively invasive incisions and approaches, in selected cases of well-defined neoformations, regardless of dimensions.
