We report two cases of successful nasal alar reconstruction using free auricular helix flaps utilizing the flow\u2010through concept. Case 1 was a 37\u2010year\u2010old man presented with a basal cell carcinoma in the nasal cavity. After radical excision, we transferred a 20\u2009\u00d7\u200920\u2009mm<jats:sup>2<\/jats:sup> free flow\u2010through auricular helix flap by interposing the T\u2010portion of the superficial temporal artery of the flap to the transected facial artery. Case 2 was a 39\u2010year\u2010old man presented with neurofibromatosis type I and a nasal alar deformity after multiple excision of the neurofibroma. We corrected the deformity with a 26\u2009\u00d7\u200922\u2009mm<jats:sup>2<\/jats:sup> free auricular helix flap. We used a flow\u2010through arterial graft of the descending branch of the lateral circumflex femoral artery to bridge the gap between the flap artery and the recipient facial artery of the submandibular region because an appropriate recipient artery was not available around the defect. Both of the flaps survived without vascular compromise and no donor\u2010site complication occurred. The esthetic results of the nasal ala were satisfactory. The flow\u2010through arterial anastomosis diverted the arterial flow to the peripheral side of the recipient artery and relieved flap congestion. These physiological properties of flow\u2010through anastomosis may stabilize the flap circulation and improve the success rate of free auricular helix flap transfer.<\/jats:p>","DOI":"10.1002\/micr.31015","type":"journal-article","created":{"date-parts":[[2023,1,30]],"date-time":"2023-01-30T05:59:46Z","timestamp":1675058386000},"page":"392-396","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Nasal alar reconstruction using the free auricular helix flap based on the flow\u2010through concept: Report of two cases"],"prefix":"10.1002","volume":"43","author":[{"given":"Hakuba","family":"Takeishi","sequence":"first","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shimpei","family":"Miyamoto","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoko","family":"Tomioka","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9287-7648","authenticated-orcid":false,"given":"Koji","family":"Kanayama","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mutsumi","family":"Okazaki","sequence":"additional","affiliation":[{"name":"Department of Plastic and Reconstructive Surgery The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,1,29]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0007-1226(75)90136-8"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-198508000-00010"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2003-42635"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/PRS.0000000000008354"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00006534-200205000-00010"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/GOX.0000000000000080"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/PRS.0b013e31817d62c5"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/0007-1226(85)90233-4"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000637-199310000-00001"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-1006852"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000637-199310000-00002"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s002669900089"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/PRS.0b013e31816a8d83"}],"container-title":["Microsurgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/micr.31015","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/micr.31015","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/micr.31015","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,22]],"date-time":"2023-08-22T15:47:40Z","timestamp":1692719260000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/micr.31015"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023,1,29]]},"references-count":13,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2023,5]]}},"alternative-id":["10.1002\/micr.31015"],"URL":"https:\/\/doi.org\/10.1002\/micr.31015","archive":["Portico"],"relation":{},"ISSN":["0738-1085","1098-2752"],"issn-type":[{"value":"0738-1085","type":"print"},{"value":"1098-2752","type":"electronic"}],"subject":[],"published":{"date-parts":[[2023,1,29]]},"assertion":[{"value":"2022-05-07","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-01-13","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2023-01-29","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
