The Application Of Autologous Cartilage Grafting In Secondary Unilateral Cleft Lip Rhinoplasty

ObjectiveUnilateral cleft lip with nasal deformation is the most common oromaxillofacialcongenital deformation，better correction of nasal deformation has been one majorproblem of plastic surgery. Surgical methods are various．However, due to a singletechnique of suture the instability of limitation and transplant of biological materials,and the complexity of the cleft lip nasal deformity, pathology, clinical manifestation,diversity, we are often difficult to obtain the most satisfactory tectonic effects. Performstudies on the anatomic structure of normal nasolabial portion and the pathologicalmechanism of secondary deformity of unilateral cleft lip，To explore the clinical effectof autologous cartilage grafting in secondary unilateral cleft lip rhinoplasty.Consequently，appropriate individualized therapeutic schemes are designed for thepatients with secondary deformity of unilateral cleft lip．MethodsThe deformities of nasal subunit such as nasal alar cartilage and cartilage of nasalseptum were analyzed preoperation，and the patients with nasal deformity of thedifferent degree were evaluated, the concha cartilage、septal cartilage and costalcartilage nasal cartilage were implanted to reshape the nasal formation on the basis ofsufficient anatoomic reposition. From2010，14patients with secondary deformity ofunilateral clefl lip were operated．The patients were followed up in the ways ofreturning hospitalusing oand Cutting open incision．And we observed the lateral nasalshape、the alar foot position、nostril symmetry、nostrils symmetry and the form. Thefollow up time is from3months to1year．Either the patient’s and the doctor’s satisfaction survey were performed meanwhile．ResultsAll of the14patients were primary healing of incision.Patients were followed up for3months to1year after surgery, by the performer, the patient and family members ofpatients from bilateral nostrils and nasal vault of symmetry, dorsum, columella and thealar and nasal tip and nasal basement ventilation dysfunction and so on various aspectsto evaluate the surgical effect. performer, patient, and the third party were all satisfiedwith the Correction results. Postoperative complications such as material leakage anddorsal deflection were not found, uricle and the chest were good, obvious localdeformity and incision scar were not found either.Conclusion1. Using no immune rejection, strong anti-infection ability, easy to survive aftertransplantation, rarely absorbs of the autologous cartilage, By takeing delay placescratches, concentric, symmetry engraving, stress, and nasal root periosteum placemeentof inferior technology, and the disadvantages of the bend deformation are corrected,unilateral cleft lip nasal deformity autologous cartilage transplantation technology ismore safe and reliable.2.On the basis of pay attention to the correction of nasal septum deviation, usingcolumellar strut cartilage transplants for alar cartilage, improve the nasal symmetryprovides a support base; Function of nasal ventilation and nose form the long-termstability is satisfied， all of these can effectively prevent the recurrence of deformities.3.Comprehensive using of Cutting open incision flange lateral cartilage transplantation,nose, nose cartilage transplantation and premaxilla rib cartilage transplantationtechnology, makes the heavy complicated nasal deformity to be a more comprehensivesystemic repaired.4.According to the nasal deformity index, in view of the different deformationcharacteristic and different gender and facial features, communicate with the patient,choose the appropriate cartilage autograft material and operation method, make the repair of cleft lip nasal deformity is more personalized.
