(a) Clinical manifestations consisted of a fistula located in the oral joint (red arrow) and an ipsilateral preauricular appendage (green arrow). (b,c) The cheek hole was injected with methylene blue using a catheter to assist in the dissection of the fistula. Traction sutures were placed on the fistula and the tissues around it, then traction was applied with the sutures to dissect the fistulous duct. (d–f) The fistula (red arrow) and normal parotid (yellow arrows) as observed on magnetic resonance imaging (MRI). (g,h) H & E staining: histopathology of the excised specimens showing salivary glands (green arrow) and the fistulous tracts (red arrow), which were enclosed in squamous epithelium. Note: Panels a, b, c, g and h refers to patient 1; Panels d, e and f refers to patient 2.
