Superficial Parotidectomy by Retrograde Facial Nerve Dissection

Introduction: Tumors of the salivary gland are relatively uncommon and represent less than two percentage of all head and neck neoplasms. Parotid gland tumor comprises 85% of the salivary gland tumors of which 80% are being benign. Superficial parotidectomy is the commonest procedure done for parotid tumors which can be performed by either anteretrograde or retrograde facial nerve dissection technique.Methods: Outcome of 60 patients after superficial parotidectomy with retrograde facial nerve dissection has been studied.Results: Total of 60 patients had been studied. Complications like facial nerve weakness, Freys syndrome, salivary fistula, and wound infection were taken into account. Among them, 13.33% patients developed temporary facial nerve weakness, followed by temporary salivary fistula, 1.6%. None of the patients developed any severe complication.Conclusion: Superficial parotidectomy by retrograde facial nerve dissection is an easy technique to carry out with low complication rate and without compromising surgical outcome.Journal of Gandaki Medical CollegeVol. 10, No. 1, 2017, page: 25-27

Abstract Objectives Carcinosarcomas of the salivary gland are rare neoplasms and have been described arising de novo or in association with pleomorphic adenoma (PA). PLAG1 and HMGA2 translocations are known to occur in PAs and carcinomas ex PA but are mutually exclusive. Methods We report a case of a carcinosarcoma in the parotid gland of a 77-year-old man with unusual anaplastic sarcomatoid giant cell morphology. Results Microscopically, a small separate PA was found adjacent to the carcinosarcoma. By conventional notion, the PA and carcinosarcoma would be considered related, as carcinosarcomas are well known to arise from PAs (carcinosarcoma ex PA). However, fluorescence in situ hybridization (FISH) assay demonstrated PLAG1 translocation in the carcinosarcoma and HMGA2 translocation in the separate PA. Conclusions These findings support that the carcinosarcoma likely originated from another PA with a PLAG1 translocation or de novo but not from the coexisting PA harboring a different translocation. To our knowledge, the case is the first to demonstrate PLAG1 translocation by FISH in a sarcomatous component of any parotid gland tumor, which may help better classify these tumors. In addition, multiple PAs are commonly found in the salivary gland, and to our knowledge, our case is the first to demonstrate that the same parotid gland can host PAs and PA-related tumors with different translocations.

Accessory Parotid Gland

Accessory parotid gland (APG) tumors account for 1% to 7% of all parotid gland neoplasms but are more likely to be malignant than main parotid gland tumors. Management of APG neoplasms entails surgical excision. Four primary approaches to resection have been described in the literature with varying facial nerve outcomes. We report a case of a 4-cm APG pleomorphic adenoma utilizing a transoral approach for excision without postoperative facial nerve injury. A transoral approach is known to mitigate patients’ cosmetic concerns; however, prior reports utilized endoscopic assistance on patients with smaller tumors. We conclude that large APG tumors can be excised through a transoral approach without undue risk to the distal facial nerves, though this transoral approach ultimately may not be appropriate for malignant neoplasms or difficult dissections.

Needle Aspiration Cytology

Pleomorphic adenoma, otherwise called as benign mixed tumour, is the most common salivary gland tumour which accounts for 60% of all benign salivary gland tumours. The clinical, radiological and histopathological presentations are varied. The tumour occurs in diverse anatomical sites and can consist of epithelial and mesenchymal components. In this case report, the patient reported with an asymptomatic swelling on the face. CT scan with contrast was advised. The clinical, roentgenographic findings and Fine Needle Aspiration Cytology were indicative of pleomorphic adenoma of the parotid gland. Treatment included partial superficial parotidectomy under general anaesthesia using the modified Blair’s incision. The facial nerve was not involved. Part of the gland along with the tumour was resected completely superficial to the facial nerve with a margin of normal tissue all around. Histopathologic examination of tissue specimen confirmed the lesion as pleomorphic adenoma. The patient was asymptomatic at 6-month follow-up.

Imaging Results

Introduction: Tumors of large salivary glands constitute about 2-3% of all head and neck tumors. Their incidence is statistically greater in males than in females, with the first symptoms usually appearing between the 4th and 7th decade of life. Material and methods: The aim of the study was to assess the usefulness of the new classification proposed by ESGS in comparison with the divisions of procedures previously valid in the literature, making a retrospective analysis of patients operated due to benign tumors of large salivary glands in the Department of Otolaryngology, Head and Neck Oncology of the Medical University of Lodz in 2012-2020. The retrospective examination was based on the material consisting of: surgical protocols, histopathological results, imaging results and clinical observations. Results: The material includes 283 patients (141 women and 142 men): 249 patients with parotid gland tumor and 34 patients with submandibular gland tumor. The most common histopathological diagnosis was pleomorphic adenoma, which was found in 105 patients (42.17%) and adenolymphoma diagnosed in 94 patients (37.75%). The most common type of surgery was superficial parotidectomy including total superficial parotidectomy in 86 patients (34.54%) and partial superficial parotidectomy in 49 cases (19.68%). Then, according to the frequency of surgery, extracapsular tumor dissection (ECD) was performed (91 patients - 36.55%). According to the ESGS classification, in most cases parotidectomy I, II (37.34% of all parotidectomies) and parotidectomy II (28.49%) were performed. In case of ECD, all tumors were located at level II. Conclusions: In summary, the new classification is aimed at unifying, but also simplifying the current nomenclature, reducing the existing nomenclature errors. By determining the exact location and extent of the tumor within the parotid gland, it facilitates postoperative monitoring of patients by ENT doctors and those of other specialties. Key words: ESGS classification, parotid gland, parotidectomy, extracapsular tumor dissection

Pleomorphic Adenomas

AbstractAn oncocytic mucoepidermoid carcinoma and an oncocytic pleomorphic adenoma occurred in a 47-year-old male and a 75-year-old female, respectively. Both presented as asymptomatic parotid gland masses without evidence of facial nerve paralysis and were treated by superficial parotidectomy. There has been no evidence of recurrence or metastasis. Oncocytic change is rare in major salivary gland mucoepidermoid carcinoma with only two previously reported cases. Marked oncocytic transformation of pleomorphic adenomas can cause their confusion with oncocytomas. Recognition of oncocytic differentiation in various salivary gland tumours is important to avoid misclassification of these lesions.
