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.
A 38-year-old man reported to the department of oral and maxillofacial surgery with a history of fall. He was diagnosed with left subcondylar, left angle and right parasymphysis fractures. He was thoroughly investigated and open reduction and internal fixation was done under general anesthesia.\nA mini-retromandibular approach was used for the fixation of the subcondylar and angle fracture, while parasymphysis fracture was reduced intraorally. On the seventh postoperative day, a diffuse swelling was observed in the left parotid region and on compressing the swelling; a watery, odorless discharge was seen from the sutured surgical wound [].\nA diagnosis of parotid fistula was made on the basis of history, location of swelling and clinical inspection of the discharge. The pressure dressing was applied for first four days after the aspiration along with antisialagogues and antibiotics. There was no significant decrease in the size of swelling or discharge.\nAfterwards we decided to use hot hypertonic saline injections. A 3% hypertonic saline was poured in a clean steel bowl and was heated to a temperature of 60 degree in an autoclave previously set at the required temperature. The mentioned site was prepared by scrubbing with Betadine solution. Five milliliter of this hypertonic solution was injected into the parotid through fistulous opening, followed by pressure dressing. The patient was instructed to continue same medicines. This procedure was repeated for three days. On the fourth day the patient did not show any signs of swelling or salivary leak as the fistula closed spontaneously.\nPressure dressings and use of antisialagogues cause fibrosis of the gland in 2 to 3 weeks;[] hence closure of fistula in 4 days was attributed to warm hypertonic saline injections. Follow-up was done for 5 months with no morbidity seen. The facial nerve and its branches were evaluated and were found to be normal.
