Clinical application of the Rhomboid-to-W technique for chronic external dental fistula

Chronic external dental fistula is associated with relatively large scars and granulation tissue around the cutaneous fistula.We treated 4 cases of external dental fistulas by the Rhomboid-to-W technique, which can be performed simultaneously to the excision of the orifice and canal of the fistula and plastic repair of the tissue defect.Few studies have used this technique to treat external dental fistula.This technique has some advantages for treating external dental fistula and is relatively easy. We report this procedure and some cases.
