ABSTRACT
Intranasal procedures were first proposed in the 1890s, and by 1917 multiple articles discussing the use of intranasal frontal sinusotomy in chronic disease had been published [1-3]. However, these procedures fell from favor and were replaced by a group of external procedures. We suspect that a high failure rate or complication rate associated with intranasal procedures caused them to disappear from the scene. Interestingly, the original articles, as well as the later works of Van Alyea and Mosher, pointed out the importance of the frontal recess in frontal sinus disease [4-7]. This concept of frontal recess disease as the cause of frontal sinusitis was apparently lost with the advent of external procedures and frontal sinus obliteration. Today, however, meticulous attention to endo-
scopic frontal recess dissection and removal of frontal recess disease in endoscopic sinus surgery has become the hallmark of successful frontal sinus treatment (8).
