The effect of chronic sympathetic and sensory denervation of the growing rabbit ear vasculature on myogenic tone in a resistance artery was studied. Unilateral superior cervical ganglionectomy and section of greater and anterior auricular nerves were performed at 4 wk of age. Compared with the contralateral control, 2 and 6 wk later, the denervated artery developed greater stretch-dependent myogenic tone. This phenomenon may partially account for the return of tone described in the denervated ear vasculature.
