A Case of Parotid Gland Salivary Fistula Treated by Tympanic Neurectomy

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

AbstractObjectives:We report two cases of congenital salivary fistula of an accessory parotid gland, and we discuss its occurrence in Goldenhar syndrome.Methods:Two teenagers complained of a congenital cheek fistula with constant salivary discharge. Computed tomography fistulography and sialography were performed. The diagnosis of Goldenhar syndrome was established based on clinical and imaging findings. Previously reported cases are reviewed and the clinical and radiological features summarised.Results:In these two patients, a salivary fistula of an accessory parotid gland was demonstrated on computed tomography fistulography, and did not communicate with Stensen's duct. Deformity of Stensen's duct and hypoplasia of the ipsilateral mandibular ramus were present. Tragal appendices have frequently been reported in such cases.Conclusion:A congenital cheek salivary fistula of an accessory parotid gland should be considered indicative of Goldenhar syndrome.

Parotid Surgery

When a patient presents with a mass at the angle of the mandible, a neoplasm within the parotid gland is a strong consideration. The parotid is the largest of the salivary glands. Terminal branches of the facial nerve are found within the gland. Their functional preservation is an important goal of parotid surgery. Risks of facial nerve injury rise in reoperative procedures and resection of cancers. Surgical principles apply in parotidectomy. In addition to facial nerve injury, a numb earlobe, contour deficit, salivary fistula, and gustatory sweating should be discussed with the patient before an operation. Most lesions can be removed after identification of the main trunk of the facial nerve, but a retrograde approach after finding a peripheral branch may be required. No randomized trials support a benefit from nerve monitoring. An intact facial nerve will usually begin to function, but months of recovery time may be needed. Permanent paralysis is rare. Salivary fistulae are usually self-limited. Many methods to ameliorate the cosmetic changes after parotidectomy have been described. None has gained ascendency.

Parotid glands were obtained from five adult (four male and one female) armadillos (Dasypus novemcinctus) which were perfusion-fixed. The glands were located in a position similar to that of most mammals. They extended interiorly to the anterior portion of the submandibular gland.In the light microscope, it was noted that the acini were relatively small and stained strongly positive with the periodic acid-Schiff (PAS) and alcian blue techniques, confirming the earlier results of Shackleford (1). Based on these qualities and other structural criteria, these cells have been classified as seromucous (2). The duct system was well developed. There were numerous intercalated ducts and intralobular striated ducts. The striated duct cells contained large amounts of PAS-positive substance.Thin sections revealed that the acinar cells were pyramidal in shape and contained a basally placed, slightly flattened nucleus (Fig. 1). The rough endoplasmic reticulum was also at the base of the cell.

Parotid Gland Carcinoma

Myoepithelial cells have been observed in the prostate, harderian, apocrine, exocrine sweat and mammary glands. Such cells and their numerous branching processes form basket-like structures around the glandular acini. Their shapes are quite different from structures seen either in spindleshaped smooth muscle cells or skeletal muscle cells. These myoepithelial cells lie on the epithelial side of the basement membrane in the glands. This presentation describes the ultrastructure of such myoepithelial cells which have been found also in the parotid gland carcinoma from a 45-year old patient.Specimens were cut into small pieces about 1 mm3 and immediately fixed in 4 percent glutaraldehyde in phosphate buffer for two hours, then post-fixed in 1 percent buffered osmium tetroxide for 1 hour. After dehydration, tissues were embedded in Epon 812. Thin sections were stained with uranyl acetate and lead citrate. Ultrastructurally, the pattern of each individual cell showed wide variations.
