Function-Preserving Neurotized Lateral Arm Free Flap in the Reconstruction of Hemiglossectomy Defects

Introduction and Methods  The glabrous, thin, and pliable texture of lateral arm flap with no loss of any axial vessel of the limb renders it a good choice for hemiglossectomy defect reconstruction. The main caveat of this flap harvest is the loss of sensation in the distribution of posterior antebrachial cutaneous nerve (PABCN). In this article, we present two strategic sites and techniques to preserve the integrity of PABCN and at the same time harvesting lateral arm flap with a lengthy lower lateral cutaneous nerve of arm for the neurotization. The outcome of this function-preserving neurotized lateral arm free flap in the reconstruction of hemiglossectomy defects is analyzed and presented in this article. Results  Ninety percent of the patients attained grade 3 score in objective assessment, leading to a significant p -value of 0.02 with this technique. All had preservation of sensation in the distribution of PABCN. Conclusion  Our technique of harvest and neurotization has brought good functional recovery of the oral cavity with preservation of PABCN.
