Clinic observation of functional repair for Bilateral cleft lip

Objective To further research the characteristics of the anatomy structure of orbicular muscle in the bilateral cleft lip,to evaluate aesthetic result of muscle functional repair. Methods The chief design principle was keeping the length of prolabium. During surgerical operation,orbicular oris need to be sufficiently dissociated from lateral labial segment and functional reconstructed in the middle of prolabial, labial sulcus and the floor of nasal are synchronously corrected,median tubercle and vermilion-cutaneous ridge are formed from lateral tip tissue. Results 87 patients who suffered from bilateral cleft lip were treated;aged from 5 months to 19 years,all parts of upper lip coordinate when the orbicular muscles move, the upper lip and nasal contours on quiet and dynamic state were satisfactory without unsightly scar. Conclusion It is a recommended processure to obtain further moving effect and perfect lip appearance using functional orbicular muscle repair and deepening prolabial vestibulum.
