Summary
Parotid gland tumors correspond to 70 – 80 % of salivary gland tumors. Approximately 80% of them are benign and the majority appear in adults. These tumors are characterized by a great diversity in their histopathological characteristics. The main complementary tests are computed axial tomography, magnetic resonance imaging, and ultrasound- guided fine needle aspiration. The treatment of benign tumors of the parotid gland is surgical and the type of resection is the subject of debate in the literature, as it varies between wide excision techniques, such as total parotidectomy, partial superficial parotidectomy of the facial nerve, and less severe procedures. invasive procedures such as transparotid excision and extracapsular dissection. The objective of this work is to present the experience of the Maxillofacial Surgery team at the Rancagua Hospital in the surgical resolution of benign neoplasms of the parotid gland with a 5- year retrospective review. An interdisciplinary preoperative evaluation was carried out between teams of Maxillofacial Surgery, Maxillofacial Pathology and Head and Neck Surgery with imaging, serological and FNAC examinations. Of all the tumors biopsied, the benign parotid neoplasms were referred to Maxillofacial Surgery for surgical resolution. Most of these tumors were operated on with preauricular approaches with mandibular subangular extension and extracapsular dissection. The patients presented few post-operative complications, with a low rate of lesion recurrence, considering a conservative surgical treatment compared to superficial parotidectomies, which is a more aggressive and widely used therapeutic alternative. This type of minimally invasive intervention is an effective alternative with a low recurrence rate and minimal postoperative complications. It is worth highlighting the importance of the Maxillofacial Surgery specialty within medical, surgical, and oncological work teams in the resolution of this type of facial neoplasms.
