          Abstract

          Parotid sialocele is characterized by a collection of saliva in the soft tissue surrounding the parotid gland. Etiology may be traumatic, iatrogenic, or laceration to the salivary duct or the gland parenchyma itself. We here report the case of a 40-year-old male patient who presented with a primary complaint of swelling on the right side of his face. The patient had a history of facial trauma, having been stabbed in the face, and the swelling developed several months after receiving medical treatment for the injury. Ultrasonography and sialography were used in order to obtain an adequate diagnostic assessment, and the patient underwent parotidectomy surgery. The objective of this article is to raise awareness regarding an uncommon post-traumatic condition involving sialocele formation in the parotid gland following facial cutting trauma.

          Post-traumatic parotid fistulae and sialoceles. A prospective study of conservative management in 51 cases.

          The management of parotid sialoceles and fistulae have been unsatisfactory in the past, and numerous methods of treatment with varying success and morbidity have been described. The present prospective study reports results of conservative therapy in 51 patients over a 3-year period. In 50 patients, the injury healed upon conservative management. During the early phase of the study, a limited conservative regimen through which the patients received nothing orally for 5 days only was used. During the latter part of the study, patients were administered nothing orally until complete healing of the injury. In terms of the time it took for healing of the injury, the differences of the two regimens (24 +/- 4 vs. 9.4 +/- 0.9 days) was highly significant (p less than 0.001). The response to conservative management depended on the severity of injury as demonstrated by sialography. Injury to minor intraparotid ducts (G1) healed in significantly less time compared with that to a major intraparotid duct (G2) or ductal injuries (p less than 0.001). There was no difference between the healing of G2 injury (10.3 +/- 1.8 days) and partial ductal transections (10.5 +/- 2.2 days) (p greater than 0.05). There was a significantly greater delay in healing with complete duct transections (21.5 +/- 3.7 days) compared with partial duct transections and G2 injuries (10.2 +/- 2.1 days) (p less than 0.01). There was no difference in the mean period for healing between salivary fistulae and sialoceles (p greater than 0.05). It is concluded that a new classification of parotid fistulae based on sialographic findings has prognostic and therapeutic value. Furthermore, the excellent results achieved with conservative therapy in this study suggest that it may be the initial treatment of choice for parotid fistulae.

            Traumatic diseases of parotid gland and sequalae. Review of literature and case reports.

            Parotid gland injuries are accompanied by a large number of sequelae. The aim of this paper is to highlight the importance of thorough management of these parotid glandinjuries especially at initial presentation in order to minimize the complications that accompany these injuries. A review of the aetiology and management of the existing cases of parotid gland injuries obtained from published journals and internet search as well as a report of two cases managed in our centre is presented in this paper. A total of about 70 cases in the previous literatures were reviewed of which assault was responsible for almost 90% of the cases. Sialoceles and fistulae were the main sequelae of these injuries. More than half of the cases (54%) were managed by conservative methods. Surgical drainage was done in about 44% cases; where the Stenson's ducts were accessible, primary repair was done. Excision of the gland was done in very few cases. The two cases managed in our centre were due to assault from broken bottles and road traffic accident respectively and both were managed by conservative methods. The first patient was a case of sialocele following the injury, which resolved within 3 weeks after the cyst formation with reduction in food intake, aspirations and external surgical drainage; while the second patient was a case of persistent fistula which healed after about 5 weeks following the trauma. Follow-up of both patients for about 3 months revealed no further leakage or accumulation of saliva. Management of these injuries involves a thorough understanding of the structure and function of the parotid gland and closely related tissues.
