This study attempts to study the relationship of the first olfactory fiber with the frontal sinus posterior wall, assessing its fidelity as a surgical landmark during frontal sinus surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Anatomic study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Fifteen cadaveric specimens were studied. Measurements were obtained bilaterally using the data from individual CT scans. Median A\u2010P was defined as the anteroposterior (A\u2010P) diameter measured just lateral to the intersinus septum, paramedian A\u2010P was measured 5 mm lateral to the septum, and maximum A\u2010P was defined as the maximum anteroposterior diameter on axial images. A surgical navigation device was used to calculate the distance between the first olfactory fiber and the posterior table of the frontal sinus.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean distance between the first olfactory fiber and the posterior wall of the frontal sinus was (4.03 \u00b1 2.7) mm on the right side and (4.2 \u00b1 2.9) mm on the left. This distance strongly correlated with the maximum A\u2010P diameter of the sinus.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>In a cadaveric model, the first olfactory fiber was found to be an average of 4.0 mm posterior to the frontal sinus. The significant variability of this distance should be considered when using the first olfactory fiber to establish the posterior boundary of a frontal sinusotomy. Drilling no further posterior than 7 mm rostral to the first olfactory fiber would be safe in 91% of patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of Evidence<\/jats:title><jats:p>NA <jats:italic>Laryngoscope<\/jats:italic>, 126:1039\u20131045, 2016<\/jats:p><\/jats:sec>","DOI":"10.1002\/lary.25696","type":"journal-article","created":{"date-parts":[[2015,10,22]],"date-time":"2015-10-22T10:02:27Z","timestamp":1445508147000},"page":"1039-1045","source":"Crossref","is-referenced-by-count":17,"title":["First olfactory fiber as an anatomical landmark for frontal sinus surgery"],"prefix":"10.1002","volume":"126","author":[{"given":"Smita","family":"Upadhyay","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head &amp;
