Abstract:
Objective To attempt to achieve a more satisfactory results in correcting the unilateral cleft lip nasal deformities caused by deficiency of the maxilla and collapse of the alar cartilage, using onlay implantation and stable fixation for implants. Methods Since 1996, the authors had implanted rib cartilage (12 cases), rib bone and cartilage (4 cases), silicon rubber (8 cases), skull bone and ePTFE (one case each) in total 26 patients with moderate to severe nasal deformities of unilateral cleft lip to elevate the retro-position alar base in hypoplastic maxillar area and to augment the buckled lateral alar cartilage in effected side. All implants were fixed by absorbable sutures on alar cartilage, and titanic screw and/or plate on maxilla under alar base. Results All wounds recovered without any complication. During 3 to 18 months follow-up postoperatively in 19 cases, the nasal appearences were significantly improved. The implants still provided support for the depressed alar base and the collapsed alar cartilage without obvious displacement, absorption and rejection. Conclusion The onlay implantation and stable fixation using suture and rigid fixation of titanic screw and/or plate for implants is reasonably good in nasal deformity correction of unilateral cleft lip advocated. The definitive effects and well-maintenance of the implant dimension and position have been documented.
