ABSTRACT

Background: Tumors of the jugal (buccal) region are rare, and their origin is variable. Schwannomas represent a particularly uncommon entity in this location. The standard treatment remains surgical excision, with the approach determined by the location and nature of the lesion. The endoscopic approach appears as a promising minimally invasive alternative, allowing for complete resection while preserving aesthetics. Case Summary: We report the case of a 57-year-old patient presenting with a jugal mass evolving over 10 years, diagnosed as an intramasseteric schwannoma by ultrasound and MRI and confirmed by histopathology with S-100 immunostaining. The patient was treated by endoscopic excision under general anesthesia via two 7 mm incisions, achieving complete tumor removal. The 6-month follow-up showed excellent functional and cosmetic outcomes, with no complications or recurrence. Discussion: Intramasseteric schwannomas are uncommon, benign tumors that develop within the nerve sheath and can be challenging to diagnose and treat due to their deep location. While traditional open surgery provides good access, it can affect facial aesthetics. In this case, using an endoscopic approach allowed for precise tumor removal with minimal impact on surrounding tissues, reducing complications and improving cosmetic results. This minimally invasive technique offers a promising alternative for treating certain buccal tumors, ensuring effective removal while preserving the natural appearance of the face.
