“…Previously, rejected due to limited working space within the oral cavity and the precarious location of the facial nerve and Stenson's duct. Theoretically, this could make injury to the nerve or duct more likely 14 . Yet, a systematic review has demonstrated no significant difference in rates of nerve or ductal injury between the APG approaches 4 .…”

Accessory parotid tumours are rare, accounting for less than 10% of parotid neoplasms. Although similar tumours affect both the accessory parotid and parotid, accessory parotid tumours are associated with higher rates of malignancy. Surgery is first line management. Standard surgical management involves a similar approach to superficial parotidectomy, despite the anterior location of these lesions. This approach requires extensive subcutaneous access and facial nerve dissection and therefore, poses significant risk. It can also result in poor cosmetic result due to scarring and Frey's Syndrome. On the contrary, a transoral approach to reduces the risk of cosmetic deformity, reduces recovery time and does not increase risk to the facial nerve. We present a case series of patients with accessory parotid masses, which have been successfully excised transoral and without endoscopic assistance.

“…Myoepithelial-differentiated cells present with fusiform and plasmacytoid morphology and, when located in ducts peripheral areas, they exhibit clear cytoplasm. The tumor presents thickness-variable area, with projections of neoplastic cells [16]. It is also observed that a benign neoplasm reveals a mixture of salivary glands epithelia [10].…”

OBJECTIVE: The Pleomorphic Adenoma is the most common among benign neoplasm derived from salivary glands and it might suggest malignancy when there is some sort of fast growth, pain, facial nerve involvement and cervical adenopathy. Its onset occurs between 40 and 60 years old and prevails on the female gender. Salivary glands tumor diagnosis depends on a precise pathological diagnosis as well as non-invasive examinations, which include ultrasonography, sialography, computed tomography and magnetic resonance imaging. The most recommended surgical treatment is the complete lesion excision, indispensable to avoid possible recurrence. Depending on the lesion situs, size, depth, and volume, the surgical technique choice for the pleomorphic adenoma may vary. The adenoma keeps developing if it is not completely removed. CASE DESCRIPTION: The present paper aims to describe a clinical case of a female melanodermic patient, aged 29 years old, who attended the MaxilloFacial Surgery and Traumatology Service of Federal University of Pernambuco complaining of an increased volume in the left submandibular region. The clinical examination revealed a well-delimited lesion in the left parotid area, presenting with a firm and painless consistency. The required ultrasonography image confirmed the initial diagnosis and the patient was referred to the surgical facility in order to undertake tumor resection with partial parotidectomy under general anesthesia.CONCLUSION: The present study concludes that pleomorphic adenoma is a benign tumor with diverse characteristics and surgical technique choice depends on the lesion depth, as well as its extension and relation with the facial nerve.

Cheek swelling can be attributed to several pathologies, including masseteric hypertrophy, diffuse inflammatory changes and neoplasia. We report an extremely rare case of bilateral cheek swelling as a result of ectopic parotid glands. This case is a young female patient with bilateral ectopic parotid glands superficial to the masseter muscle and the zygomatic arch, demonstrated by the enhanced computed tomography (CT).Medical history, clinical features, videography and management of this case are described. After two years of observation, no significant change in symptoms was observed on this patient. Besides, we conducted a case report and systematic review of cases of ectopic parotid gland. A literature search was performed using PubMed, Web of Science, and Ovid electronic database. A total of 144 papers were retrieved and only one paper was included in the systematic review. In conclusion, bilateral ectopic parotid gland is extremely rare and easily confused with other lumps in the area of head and neck. CT, magnetic resonance imaging (MRI), ultrasound imaging and parotid sialography allow for noninvasive diagnosis of ectopic parotid gland. If the parotid ectopic is highly suspected and the patient does not have obvious symptoms, conservative treatment and long-term observation follow-up are recommended.
