Abstract
Purpose: To correct the upper lip depression after the correction of unilateral cleft lip, autologous grafts such as bone, dermal, fascial grafts and fat injections or alloplastic implants are used. Transplanted bones, dermis and fascia have a tendency to be absorbed and have donor morbidity. Fat injections are absorbed inconsistently and alloplastic implants have problems such as foreign body reactions, protrusions and infections. Authors corrected the upper lip depression using conchal cartilage graft in unilateral cleft lip deformity and the results was analysed with photos. Methods: 26-unilateral cleft lip and 2-microform cleft lip cases, totally 28 cases were performed. Their mean age was 21.89 years. The male and female cases were 12 and 16, respectively. Under anesthesia (general: 18 cases and local: 10 cases), cavum conchae (n=8), cymba conchae (n=16) and whole conchae (n=4) were harvested. Transversely cut the margin of the obtained cartilage, we cut out the most bent portion and put a partial-thickness incision on concave surface in cases of excessive convexity. Then, we performed the onlay graft of the conchal cartilage via scar revision site in unilateral cleft lip and via the reconstruction site of the cupid bow in microform cleft lip. The augmentation of the upper lip was evaluated with photos. Adapting the baseline connecting between the both cheilions as a horizontal standard line, we measured the highest point among the tangents between the upper lip and nose (point a), the lowest point (point c), the middle point between a and c (point b) and the vertical line from the alare (point d) to the horizontal standard line. To assess the postoperative symmetry, we compared cleft side upper lip contour index (%) A,B,C,D=(a,b,c,d)-ch ${\times}$ 수식 이미지 100/(ch-ch) and non-cleft side upper lip contour index (%) A',B',C',D'= (a',b',c',d')-ch ${\times}$ 수식 이미지 100 / (ch-ch).h) Results: After the surgery, no complication was found except in one case which double layers graft performed in the cleft lip deformity, the lateral portion was protruded. The upper lip contour index, the difference of A and A' were-0.83%, and thus the mild depression was persisted. Difference of B and B', C and C', D and D' were 0.83%, 1.07%, 0.90%. There were statistically significant difference, and thus the depression of upper lip were improved generally. Conclusion: Authors performed the onlay graft of the conchal cartilage in unilateral cleft lip deformity and found that the depression of the upper lip was well corrected except the uppermost part when photogrammetrically analyzed.
