A 10-year-old male child presented with history of intermittent discharge of watery fluid from an opening in the right cheek since birth. The discharge increased on feeding/eating and was not associated with any swelling or pain. There was no previous history of swelling, redness, pain, or injury to the region. He was otherwise healthy and had normal developmental milestones.\nPatient had normal general/systemic examination with vital parameters. Local examination revealed a small punctum on the right side of the face, at a distance of about 2.5 cm from the angle of the mouth and 1 cm inferior to a line joining the tragus and angle of mouth []. Expression of clear serous fluid on local massage was seen. No associated palpable mass or tenderness was noted. Oral examination was normal with normal Stenson's ducts opening bilaterally.\nBilateral pre-aural appendages were noted on regional examination, two on the right side anterior and anteroinferior to the tragus and one appendage on the left side just anterior to the tragus [Figure and ].\nAs a part of the diagnostic work-up, ultrasonography, sono-fistulography, contrast digital fistulography, contrast digital sialography and contrast CT fistulography [] were done. Laboratory analysis of the fluid revealed raised salivary amylase levels (7800 IU/mL), which confirmed the diagnosis of a salivary fistula. Contrast fistulography revealed an opacified tubular shaped density visualized with opacification of soft-tissue area noted on the plain image. No intra oral spillage of contrast was seen.\nOur patient was successfully managed by a simple surgical technique, described below:\nThe procedure was performed under general anesthesia with local infiltration of 1 in 100,000 adrenaline around the fistulous opening to minimize intra-operative bleeding. Methylene blue was then injected into the fistulous opening using a 26-gauge needle (blunt tip) under microscopic magnification. An incision-along skin crease enclosing fistulous opening was given. The duct was dissected for about 1.5 cm. Then brought out to the mucosal surface through buccinator muscle opposite the first upper molar tooth. The duct was secured in place using absorbable sutures. Skin incision was closed. Pre-auricular tags were also excised. Figures and are showing the dissection.\nPost-operatively, patient was kept on nil by mouth for 24 h and put on intravenous fluids, antibiotics, atropine and analgesics. On stimulating the accessory gland the saliva was found dribbling from the transposited duct opening. Patient was discharged on oral antibiotics and analgesics on the 3rd post-operative day. Her sutures were removed on the 6th day. Histopathological examination of the tissue/fluid adjacent to fistulous tract showed no underlying malignancy or evidence of any specific (granulomatous) disease. At 2 weeks later sialogram was carried out which confirmed the patency of the duct. Our patient was followed-up 3 months later and was found to have successful healing of her wound with no complications or recurrence. Figures and are showing the post-operative status.
A 24-year-old otherwise healthy male patient reported with the chief complaint of watery discharge from a swelling on the right side of the face for the past 1 month. Patient had a history of mandibular condylar fracture from a road traffic accident, for which he was treated elsewhere with direct open reduction and internal fixation of the condyle. The surgical scar was observed on the post-ramus swelling, and there was fistula in one end of the scar that was about 0.5 cm in diameter [Figures and ]. The wound was 2 cm deep and had a healthy granulating margin with no obvious clinical signs of infection, but the wound continued to have a drain of a copious amount of clear, watery, and odorless fluid.\nOn examination of parotid papillae, intraorally, active secretion was present on the left side, but not on the right side. Neurological examination revealed no motor loss due to severance of any branch of facial nerve in the affected side. Location of the fistula and nature of the discharge suggested a laceration of the right parotid gland substance resulting in a sialocele and a right parotid fistula formation. Siaologram confirmed the clinical suspicion [Figures –].\nIn the present case, trauma in the parotid glandular substance lead to formation of sialocele by accumulation of extravasated saliva into glandular parenchyma. It was decided to create a controlled internal fistula with drainage intraorally under local anesthesia. After standard preparation, intraorally, a 1-cm long incision was placed on external oblique ridge behind the third molar. A small artery forceps was forced through the superficial fascia of masseter reaching the sialocele. With the help of this forceps, approximately 5-cm long, slender, sterile, punched plastic tube of diameter 4 mm was positioned with one end in the glandular substance and the other end in the mouth, seated along the vestibule, ensuring complete convenience. The tube was secured by suturing it to the mucosal surface of the cheek []. Extraorally, the wound was sutured primarily in layers, followed by compression dressing on the cheek. The patient was covered with Ciprofloxacin and Metronidazole for 5 days to prevent superadded infections. Saliva stopped draining by 10th postoperative day of surgery. The tube was subsequently removed to enable the internal fistula to close and salivary secretions to drain through the right Stenson's duct normally. The patient's recovery was uncomplicated and follow-up was done for 5 months and lost to follow-up.
