A line from Nasion and the incisive canal was set, the perforation was centered in the area 1ab of the septum mucosa avoiding vestibular skin.

It starts superiorly at the middle turbinate axilla projection, then followed a caudal direction along the nasal septum, reaching the posterior border of the perforation. This incision should not be started posterior to the middle turbinate axilla projection in the septum, because the mean distance between this point and the entrance of the first AEA branch in the nasal septum is between 5.5 mm and 8.7 mm.<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">9</span></a> Moreover, the medial projection of the axilla is also related to the S-point, a highly vascularized area posterior to the septal body.</p><p id="par0035" class="elsevierStylePara elsevierViewall">Once the anterior incision passes the posterior edge of the SP it continues towards the floor of the nasal fossa. Once the anterior incision reaches the nasal floor it travels laterally posteriorly to the piriform aperture until the lateral wall of the inferior meatus is reached. The inferior incision later travels posteriorly inside the inferior meatus until it reaches the inferior turbinate tail, then it goes back down towards the floor of the nasal cavity until the junction of the hard and soft palate (JHSP).</p><p id="par0040" class="elsevierStylePara elsevierViewall">Finally, the posterior vertical incision goes from the JHSP towards the roof of the nasal fossa travelling cranially. The posterior incision was progressively made at a height of 10, 20, 30, and 40 mm from the junction between the septum and the floor of the fossa. Each time the incision was elongated, the flap was rotated clockwise anteriorly.</p><p id="par0045" class="elsevierStylePara elsevierViewall">Once the flap was rotated, the value of the rotation angle of the flap on the septal surface was calculated, taking reference to the resulting rectangular triangle on the septal surface and using the Pythagoras' theorem.

At this point, with a rotation angle of 60° (63° in our case), the flap completely covers this area, and nearly the entire area 1, except for the most inferior and posterior margin. Elevating the incision further increases the excessive thickness of the flap. However, the angle of rotation does not necessarily increase, because with a 20 mm incision the upper anterior portion of area 1 had already been reached.</p><p id="par0075" class="elsevierStylePara elsevierViewall">An inferior incision including only the nasal floor and not the inferior meatus is not enough to cover the most superior and anterior margin of the area 1a with a 20 mm high posterior vertical incision (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>.B). Even though the nasal floor can reach the uppermost portion of area 1 with a 30 mm posterior incision (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>.C), this design generates additional redundant tissue in the upper portion of the septum, it does not cover the most inferior and posterior margin of the rest of area 1, and it does not fully cover the anterior margin. All of these factors in addition to the retraction of the flap itself in the postoperative period can increase the risk of reperforation.</p><p id="par0080" class="elsevierStylePara elsevierViewall">Additionally, this anatomic dissection helps to visualize the concept that in order to avoid redundant tissue at the level of the flap pedicle, which is in the first centimeter posterior to the middle turbinate axilla.<a class="elsevierStyleCrossRefs" href="#bib0020"><span class="elsevierStyleSup">4,9</span></a> It is recommended to start the anterior vertical incision superiorly at the level of the MT, and then direct the incision towards the posterior edge of the perforation (As in <a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). Moreover, the area of the flap that covers the anterior edge of the perforation is limited to the inferior incision, therefore we must extend the flap in the nasal floor laterally until the inferior meatus. The more lateral the inferior incision is made, the closer the flap will be to the anterior septal edge.<a class="elsevierStyleCrossRefs" href="#bib0045"><span class="elsevierStyleSup">9,10</span></a></p><p id="par0085" class="elsevierStylePara elsevierViewall">A short posterior vertical incision can also avoid transecting the most superior branch of the posterior septal artery (PSA).<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a> The superior branch of the PSA contributes along with AEA, and inconstantly with the posterior ethmoidal artery (PEA) to an arterial arch called the S-point. The S-point is a highly vascularized area situated in the superior portion of the nasal septum, at the level of the middle turbinate and posterior to the septal body/tubercle. In this way, by sparing the superior branches of the PSA, the flap remains better vascularized.</p><p id="par0090" class="elsevierStylePara elsevierViewall">Anterior NSP is challenging and demands large flaps to cover the anterior aspect of the defect. Considering the healing process during the postoperative period, it was estimated that the flap should be one third bigger than the perforation to avoid re-perforation of the anterior margin. The AEA flap was originally described for “anterior perforations” (without exactly defining the precise location of an anterior perforation) (4). Based on the anatomical dissection of our study, we conclude that an AEA flap can cover almost all of area 1, except for the most posterior-inferior margin. Therefore, the larger the size of a perforation in Area 1 at the expense of its posterior and inferior border, the greater the risk of not properly covering both the anterior-superior and posterior-inferior border. The length of the inferior incision cannot be less than the distance between the most anterior-superior point and the most posterior-inferior point of the NSP (The oblique diameter). Based on this observation, and the retraction of the tissue after the surgery, we recommend using an alternative technique that allows more tissue to be obtained on those cases of anterior NSP (area 1) in which the posterior edge of the perforation is in area 2.<a class="elsevierStyleCrossRefs" href="#bib0050"><span class="elsevierStyleSup">10,12–15</span></a></p><p id="par0095" class="elsevierStylePara elsevierViewall">This study has some limitations. The dissection was only performed on a single specimen, it was only possible to assess the size and location of a single perforation, and the measurements were made with a millimeter ruler. Despite the limitations, we consider this work has been useful to better visualize and understand the rotation pattern of this type of flap, and therefore tailor a better surgical approach of SP.</p></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0080">Conclusion</span><p id="par0100" class="elsevierStylePara elsevierViewall">An AEA flap with a posterior vertical incision of 20 mm high, with a design that includes the mucosa of the nasal floor, and the inferior meatus, could be enough to achieve adequate rotation of an AEA flap and cover all the margins of an anterior SP.</p></span><span id="sec0030" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0085">Funding information</span><p id="par0105" class="elsevierStylePara elsevierViewall">This research has not received specific aid from agencies from the public sector, commercial sector or non-profit entities.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0090">Conflict of interest</span><p id="par0110" class="elsevierStylePara elsevierViewall">None of the authors have a conflict of interest for this study.</p></span><span id="sec0040" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0095">CRediT authorship contribution statement</span><p id="par0115" class="elsevierStylePara elsevierViewall"><span class="elsevierStyleBold">Octavio Garaycochea:</span> Conceptualization, Data curation, Formal analysis, Investigation, Methodology, Project administration, Validation, Writing -
