Abstract: ObjectiveTo explore the effect of the lateral island flap with neurovascular pedicle of finger on reconstruction of the sensory function of thumb and forefinger pulp.MethodsSensory functions of 9 thumb pulps and 7 forefinger pulps were reconstructed by the lateral island flap with neurovascular pedicle of ring finger and middle finger.ResultsAll 16 island flaps were survived. Follow-up survey was 6 months to 2 years. The appearance and texture of flaps were satisfactory with sensory function being S3-S3⁺ grade.ConclusionThe lateral island flap with neurovascular pedicle of ring finger and middle finger is a good and reliable method to reconstruct the sensory function of thumb and forefinger pulp.

Key words: island flap, finger pulp, reconstruction of sensory function
