Methods The volar digital advancement flap, the lateral digital neurovascular island flap, the lateral digital reverse island flap and the dorsal digital flap had been undergone for 78 patients. The size of the pulp defect varied from 1.0 cm±1.0 cm to 3. 0 cm ± 3. 5 cm. Results All flaps were survived. The follow-up was 1 to 3 years. The appearance of the pulp was satisfactory with good sensory recovery. Conclusion The digital flap is an ideal method for repair of pulp loss, which is a simple and efficient procedure with minimal donor site morbidity. 2 refs.China Medical Abstracts(Surgery)展开更多
