Abstract
Background: Tip refinement procedures are still controversial in secondary unilateral cleft rhinoplasty. The aim of this study was to assess whether the septal extension graft improved nasal and tip deformity and achieved a normal profile with clinical and three-dimensional morphometric analyses.
Methods: A consecutive series of 194 skeletally mature patients with unilateral cleft were included and analyzed. All had undergone secondary open rhinoplasty, performed by a single surgeon, with the use of the septal extension graft between 2013 and 2021. Clinical data were collected, and three-dimensional morphometric measurements were performed. An age-, sex-, and ethnicity-matched normal group was included for comparisons.
Results: The authors' standard procedures included open approach combining reverse-U incision, septal extension graft, dorsal augmentation, lip revision, and vermilion augmentation. The postoperative outcome showed significantly increased numerical values (nasal bridge length, nasal height, nasal tip projection, nasal dorsum angle, columellar angle, columellar-lobule angle, nostril height ratio, nasal surface area, nasal volume) and decreased numerical values (alar width, tip/middle deviation, nasal tip angle, labial-columellar angle) compared with the preoperative morphology. The postoperative measurement showed significantly higher numerical values (nasal protrusion, tip/middle deviation, nasal dorsum angle) and lower numerical values (columellar-lobule angle, nostril height ratio, alar width ratio) compared with the control group.
Conclusions: This study revealed that the authors' secondary cleft rhinoplasty significantly improved the underprojected, up-rotated, deviated, and poorly defined tip and short nasal bridge deformities. The technique could result in the nose of the patients with cleft lip nasal deformity being closer to that of the normative profile.
Clinical question/level of evidence: Therapeutic, IV.
期刊介绍：
For more than 70 years Plastic and Reconstructive Surgery® has been the one consistently excellent reference for every specialist who uses plastic surgery techniques or works in conjunction with a plastic surgeon. Plastic and Reconstructive Surgery® , the official journal of the American Society of Plastic Surgeons, is a benefit of Society membership, and is also available on a subscription basis.
Plastic and Reconstructive Surgery® brings subscribers up-to-the-minute reports on the latest techniques and follow-up for all areas of plastic and reconstructive surgery, including breast reconstruction, experimental studies, maxillofacial reconstruction, hand and microsurgery, burn repair, cosmetic surgery, as well as news on medicolegal issues. The cosmetic section provides expanded coverage on new procedures and techniques and offers more cosmetic-specific content than any other journal. All subscribers enjoy full access to the Journal''s website, which features broadcast quality videos of reconstructive and cosmetic procedures, podcasts, comprehensive article archives dating to 1946, and additional benefits offered by the newly-redesigned website.
