Abstract
BACKGROUND: Cleft rhinoplasty is a challenging form of nasal correction of both esthetic and functional deformities. The septal cartilage in many Asian patients are not sufficient and weak. Does a combination of the septal cartilage and the bony septum have both esthetic and functional benefits to secondary unilateral cleft rhinoplasty? PATIENTS AND METHODS: Thirty patients with a unilateral cleft lip palate underwent open rhinoplasty from October 2018 to January 2021. After preserving a 10 mm L-strut, the posterior cartilaginous and bony septum were harvested as an integrative unit. The osteocartilaginous graft was used as a caudal septal extension graft and an extended spreader graft. Correcting the asymmetry of the tip and tip projection followed. The intraoperative harvested composite graft was analyzed. Acoustic rhinometry and the 3-dimensional anthropometric measurements of the external nose were assessed before and after surgery. RESULTS: The osteocartilaginous unit was much larger than the cartilaginous part of this unit. The mean nasal tip height and the nasolabial angle increased significantly after surgery. The measurement of cross-sectional areas and volumes by acoustic rhinometry revealed that septorhinoplasty provided a significant increase in the function of both nasal cavities. CONCLUSIONS: This septal bony cartilaginous graft is effective for cleft lip nasal deformity when correcting the deviated septum, creating a supporting frame to correct the nasal tip asymmetry, improving function.
