Overview
Parotid gland fistulas represent abnormal connections between the parotid gland and adjacent structures, often presenting with symptoms like swelling and otorrhoea, frequently resulting from trauma or infection 12.Diagnosis
Clinical Presentation: Intermittent parotid swelling, otorrhoea, and history of trauma or infection 1.
Imaging: MRI or CT may help identify the fistula tract and associated masses 1.
Histopathology: Examination of excised tissue can confirm etiology, such as fibrotic remnants or infectious processes 1.Management
Surgical Intervention: Superficial parotidectomy to excise the fibrotic mass and close the fistula 1.
Addressing Underlying Cause: For infectious causes, particularly tuberculosis, palatine tonsillectomy may be necessary alongside anti-tuberculous therapy 2.
Anti-tuberculous Therapy: Specific drug regimens should be tailored based on local resistance patterns, though specific doses are not detailed 2.Special Populations
Pediatrics: Parotid fistulas in children often result from infection, particularly tuberculosis, requiring comprehensive management including tonsillectomy 2.Key Recommendations
Perform superficial parotidectomy for symptomatic parotid fistulas with associated masses to achieve complete resolution 1 (Evidence: Moderate).
In pediatric cases of parotid fistulas, consider palatine tonsillectomy in addition to anti-tuberculous therapy if tuberculosis is suspected 2 (Evidence: Moderate).
Address underlying infectious causes comprehensively, including surgical removal of primary sites like the tonsil, to improve outcomes 2 (Evidence: Moderate).References
