2.5.1. Sinusectomy and primary closure
An ellipsoid incision was made separately in such a way that tissue loss
will be minimal, and enclosing all primary and secondary sinus orifices
at both sides separately using a No. 11 surgical blade. With the help of
the stylet, the fistula tract was excised subcutaneously with blunt and
sharp dissections (Figure 1a, 1b). Attention was paid not to leave any
diseased tissue at the margins after excision, and bleeding points were
cauterized for hemostasis. The subcutaneous dead space that forms after
the excision was closed subcutaneously with absorbable sutures.
Subsequently, the wound at both sides of the fistula was dressed with
subcutaneous absorbable suture (Figure 1c, 1d).
