Measurement of the frontal beak, anteroposterior depth of the frontal sinus, and interorbital distance was performed. There were 4 specimens with poorly pneumatized frontal sinuses that were excluded from the study. Eight cadaveric heads (16 sides) were dissected and a MELP with bilateral transcaruncular and Lynch incisions for access to the lateral frontal sinus was performed. Under image guidance, measurements extended from the midline crista galli to the most lateral point of the frontal sinus visualized using a 0\u2010degree endoscope with straight suction and a 30\u2010degree endoscope with curved suction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The proportion of the ipsilateral frontal sinus accessed through the contralateral nare with a 0\u2010degree endoscope and straight suction using a MELP only, a MELP with transcaruncular approach, and a MELP with Lynch incision, respectively, averaged 41.6%, 51.6%, and 58.9% on the right, and 48.9%, 47.1%, and 61.2% on the left.
