구순열 비변형에 있어서 복합적 골이식술 = THE NEW TECHNIQUE OF CRANIAL BONE GRAFT TO CORRECT HYPOPLASTIC PYRIFORM APPERTURE IN THE CLEFT LIP NOSE DEFORMITY

다국어 초록 (Multilingual Abstract)

General anatomical structure of the Cleft Lip Nose(CLN) deformity have been well documented. Hypoplastic pyriform aperture is major external factor which causes the CLN deformity and also represent such deformities of alar cartilage, nasal tip and septal deviation, which has been well explained with the concept of tilted tripod by Hogan & Converse in 1971
The correction of hypoplastic pyriform aperture which tilts nasal tripod gives satisfactory result of symmetric nasal tripod including its base. For the correction of hypoplastic pyriform aperture autogenous rib bone, iliac bone, calvarial bone, autogenous cartilage graft, homogenous cartilage graft and implant have been used. Although each method has its own pros & cons, autogenous bone graft have been used. Altough each method has its own pros & cons, autogenous bone graft have been most widely used because of its high survival rate, low postoperative complication rate and logterm stability. Recently, the calarium has become the favorite source of autogenous bone graft since it has many advantages. However it is not easy to fabricate bone graft exactly to fit in the defect and enhance rather wide contact with recipient site to lessen late absorption rate.
Authors used outer table of table of calvarial bone, dust and fibrin sealant mixture for the correction of collapsed pyriform aperture. The outer table of calvarial bone play a role to scaffold bone dust and fibrin sealant mixture were used to fit graft material and therefore increase the contact between the donor site and recipient site and molding graft margin for better contouring.
Author successfully treated 8 patients of CLN deformity by this fecnique, 6 patients were male & 2 were female. The youngest was 5 years of age, the oldest was 28 years & 4 patients were under 15 years.
We corrected the hypoplastic pyriform aperture with calvarial bone dust & fibrin sealant mixture, and achieved satisfactory results. We represent our msthods & cases with review of litelatures.
