[The treatment principles of frontal sinus tract after the frontal approach craniotomy].
OBJECTIVE
To investigate the causes, clinical manifestation and treatment principles of frontal sinus tract after the frontal approach craniotomy.


METHODS
The clinic data of 13 patients with frontal skin sinus tract after the frontal approach craniotomy were retrospectively analyzed. All of them were described in the clinical record to have undergone frontal sinus mucosa pushing down or shaving and bone wax filling in the frontal sinus during the surgery, of whom 3 cases had history of frontal abscess incision drainage. All patients were performed endoscopic frontal sinus surgery and forehead skin sinus tract excision and suture.


RESULTS
All of the patients successfully recovered after one-stage operation, and the frontal skin sinus tract was healed.


CONCLUSIONS
The frontal approach craniotomy with postoperative frontal sinus tract was related with the improper use of bone wax tamponade and sealing of frontal sinus. The treatment principles were to remove bone wax, remove inflammatory granulation tissue around the sinus tract, and to open frontal sinus and promote frontal sinus drainage.
