Surgical management of the frontal sinus is difficult for several reasons. First, access to the frontal sinus through complicated and varied frontal recesses requires anatomical knowledge and operative skill. Second, not all of the mucosa of the frontal sinus is accessible with curved surgical instruments. Third, once fenestrated, a frontal drainage pathway has a high likelihood of stenosis during the follow-up period. Draf type II and III procedures were introduced in 1991 [1], and since then, have been widely used for frontal sinus diseases.
