However, many clinicians are concerned about the postoperative effect of removing the ANS<\/jats:styled-content> on the nasal outline, as the ANS<\/jats:styled-content> is integral to supporting the nose. This study aimed to describe the technique of ANS<\/jats:styled-content> bone grafting and to investigate postoperative effects of bone harvesting from the ANS<\/jats:styled-content> on the overall nasal shape.<\/jats:p><\/jats:sec>Material and methods<\/jats:title>Fifteen patients with single maxillary first incisal rehabilitation using dental implant were enrolled in this prospective clinical study. Simply by extending the subperiosteal dissection in the same surgical field without additional local anesthesia, a bone block of about 0.25\u20130.5\u00a0ml could be harvested from the ANS<\/jats:styled-content>. Nose width (NW<\/jats:styled-content>), nasolabial angle (NLA<\/jats:styled-content>), and nasal tip depth (NTD<\/jats:styled-content>) were measured and analyzed by lateral and frontal photographs taken preoperatively (T0), and at postoperative 1\u00a0week (T1), 3\u00a0months (T2), and 6\u00a0months (T3). Postoperative complications were also recorded.<\/jats:p><\/jats:sec>Results<\/jats:title>A significant increase in NW<\/jats:styled-content> and decrease in both NLA<\/jats:styled-content> and NTD<\/jats:styled-content> were found at T1 (P\u00a0<\/jats:italic><\u00a0<\/jats:italic>0.05). At T3, NW<\/jats:styled-content>, NLA<\/jats:styled-content> and NTD<\/jats:styled-content> returned to preoperative measurements at T0 without major complications.<\/jats:p><\/jats:sec>Conclusions<\/jats:title>The ANS<\/jats:styled-content> could be an effective and easily accessible intraoral source for autologous bone. Despite acute soft tissue swelling, the net postoperative effects of removing the ANS<\/jats:styled-content> on the overall nasal shape, including on nasal tip collapse or widening of the nose base, were negligible.<\/jats:p><\/jats:sec>","DOI":"10.1111\/j.1600-0501.2012.02428.x","type":"journal-article","created":{"date-parts":[[2012,2,16]],"date-time":"2012-02-16T02:39:45Z","timestamp":1329359985000},"page":"618-622","source":"Crossref","is-referenced-by-count":14,"title":["Postoperative
