title: Spontaneous sensory recovery in non-innervated radial forearm flaps used for head and neck reconstruction.
abstract: Although several studies have reported the use of reinnervated microvascular free flaps for oro-pharyngeal reconstruction, it has been known for some time that non-innervated flaps demonstrate spontaneous sensory recovery. This study sought to evaluate the degree of such spontaneous recovery in 50 radial forearm flaps used for mucosal reconstruction of head and neck ablative defects. The recovery of sensation to pinprick, light touch and temperature was tested a mean of 38 months (range 15-71) after surgical insetting. Two-point discrimination was also sought. Although 18 flaps (36%) remained anaesthetic, partial recovery in one or more modalities was present in 28 patients (56%). A recovery in all modalities of sensation in at least two-thirds of the flap area was recorded in 4 patients (8%). The mean 2-point static discrimination for fascio-cutaneous flaps was 18.9mm.
