A 1-year-old girl presented with serous discharge from the right cheek since birth which increased on chewing. On examination, there was a 1 mm × 1 mm cutaneous opening over the right cheek, 2 cm lateral to the angle of the mouth along with bilateral preauricular skin tags []. Intraoral examination and duct opening of parotid and submandibular gland was normal on both sides. Sinogram with a 24G cannula showed a thin tubular tract directed posteromedially from the external opening on the cheek into the region of the Stensen's duct/parotid gland []. There was no communication with the oral cavity or mandible. Under general anesthesia, the external opening was cannulated with a 24G intravenous plastic cannula and methylene blue injected []. With circumferential fine dissection around the external opening, the fistula tract was separated from the skin and subcutaneous fat of the cheek and brought into the oral cavity. Further intraoral dissection showed the tract initially going vertically down for 2 cm then turning posteriomedially for 1 cm to finally opening into the right Stensen's duct near the lower part of the parotid gland []. The fistulous tract was transfixed and ligated at its origin in the duct and excised in toto []. At 1-year follow-up, she has a negligible scar with a good cosmetic outcome [].
A 1-yr-old girl presented with a salivary discharge at the facial skin of her right cheek. CT sialography was done and a sialo-cutaneous fistula from an accessory parotid gland was diagnosed (). She also had a skin tag on the tragus of the right ear. At that time, surgical excision was considered at a later age. At the age of five, she visited the outpatient clinic for definitive treatment. The clinical examination demonstrated a 1 mm-sized opening located at the facial skin 1 cm lateral to the angle of mouth. The salivary discharge was clear and serous. The salivary flow rate was calculated by a cotton ball test. It revealed that the flow from the accessory gland was about 10% of the total flow of a parotid gland. According to our previous experience (), fistulectomy was scheduled, but aesthetic considerations for the young girl made the surgical plan change to more conservative management. Under general anesthesia, the 6 cm-long fistula tract was identified with a lacrimal probe. Intraoperative ultrasonography was done to demarcate the accessory parotid gland. Although the accessory gland was too small to be clearly identified, 16 IU of botulinum toxin was injected to the accessory gland under ultrasound guidance. After thin adhesive film was attached on the buccal skin around the fistula opening to prevent spillage of corrosive agent from unwanted skin injury, about 2 mL of 40% TCA solution was injected into the tract with a small metal suction tip (). Thirty seconds later, all the solution was removed with suction and squeezing. This procedure of TCA cauterization was repeated twice. There was no immediate complication postoperatively.\nAfter several days, a tensely inflated sialocele formed and the opening was found to be completely closed up. Aspiration was done with long subcutaneous tunneling from behind so as not to make an iatrogenic sialo-cutaneous fistula. After 4 sessions of weekly aspiration, the sialocele did not recur. During one year follow-up, there was no more salivary leakage or sialocele. Moreover, the aesthetic result was very satisfactory.
