RESUMO
INTRODUCTION: The management of parapharyngeal space (PPS) tumors is surgical, but the approach remains a challenge. Attention should be paid to avoid intra-operative bleeding, cranial nerves damage, and external scars. PRESENTATION OF CASE: The authors report a case of a 23-year-old female, with complaint of progressive, painless swelling just below the right angle of the mandible of 6-month's duration. Magnetic resonance imaging images reported the presence of an oval-shaped expansive lesion (maximum diameter 3âcm), from the lower polar region of the parotid gland while fine needle aspiration cytology (FNAC) was not diagnostic. We performed a Trans Oral Robotic surgical excision of the tumors with Da Vinci Robot. DISCUSSION: Thanks to a detailed magnification, the authors were able to reach the PPS region through the tonsillar fossa saving the palatine tonsil without any significant bleeding or nerve lesions. The histological examination confirmed the diagnosis of pleomorphic adenoma of parotid gland. The decision on which surgical approach to be used is determined by site, size vascularity, histology of the tumor, and knowledge of radiological images. CONCLUSION: There is not only 1 surgical approach for PPS tumors but the surgeon must know all the different options and possible outcomes. Transoral Robotic Surgery approach with Da Vinci could represent a valid option with a good knowledge of Robot surgical instruments and a detailed preoperative plan.
