Purpose: Most surgeons have used autogenous cartilage for columella strut graft. But the supply of autogenous cartilage is often limited. So, this study is to investigate the usefulness of biodegradable plate as columella strut material. Methods: We studied 19 patients who have secondary cleft nasal deformity. Patients were divided into two groups. Group A patients who were not closed their growth plate underwent columella strut graft only with biodegradable plate through endonasal approach. The biodegradable plate was inserted between nasal tip and anterior nasal spine. Group B patients were closed their growth plate. They had an operation for columella strut graft with biodegradable plate fixed with autogenous conchal cartilage. If nasal tip projection was insufficient, we performed additionally onlay graft on nasal tip with autogenous soft tissue or remnant cartilage. Results: As a result of mean 14 months follow-up, we achieved a good nasal tip projection, narrowing of interalar distance and symmetrical nostril shape. No specific complications were reported except 2 cases, which were the extrusion of biodegradable plate into the nasal cavity and Staphylococcus aureus infection. Conclusion: The columella strut graft using biodegradable plate is simple and effective method. Biodegradable plate can be a good substitute for columella strut in patients who can not use autogenous cartilages.

A General survey on the cleft lip and/or palate patients in Pusan National University Hospital was done. The conclusions were as follow. 1. In gender ratio, male was higher than female. 2. In the cleft type, unilateral cleft lip and palate, cleft lip and alveolus, and bilateral cleft lip and palate in higher ratio order. Left unilateral cleft lip and palate was higher than right in ratio. 3. In first hospital visiting age for dental treatment, the group from 6 years old to 12 years old was most and in that the age group for attending elementary school (about 7-8 years old) showed especially higher ratio. The large majority of patient were born in 1980's and lived in Pusan metropolitan city, KyungSangNamDo. Especially, most of them lived in the neighboring Held of Pusan National University Hospital. 4. Class III skeletal pattern and Angle's Class III molar relationship was most prevalent. Angle's Class II molar relationship showed relative higher ratio because tooth loss and malposition. 5. Primary lip closure in 3 months, secondary lip closure in 6-7 years old, palatal closure in 12-16 months and bone graft in 8-10 years old were operated mostly. Rhinoplasty and scar revision were operated in too early age so the need of infantile orthopedics must be considered. 6. Maxillary expansion and protraction were operated mostly in 8-11 years old but operating in primary dentition must be considered. 7. Tooth alignment were started mostly in mixed dentition and consideration about prosthodontic treatment and retention will be need. 8. In tooth anomaly, tooth malformation and missing were most prevalent.
