Reccurent preauricular infected fistula

A 19 year old girl with reccurent preauricular infected fistula for few years.
She was operated twice by GP in Sarawak.
Same problem started on 28 may 2022. I treated her with cal phos and gun powder.
At her last visit few days ago her fistulas has closed. thanks to Dr Tariq

Note :

• cal phos is the go to med for fistulas
• gun powder works well for pus filled infections
• gun powder can be used both orally and topically
