Chronic bilateral T1 denervation in women with macromastia.

Abstract:

INTRODUCTION:The objective of this study was to identify the pattern of neurological deficits and document electrophysiological changes in women with macromastia. METHODS:Patients with macromastia and neurological complaints underwent clinical evaluation and electrodiagnostic (EDx) studies of the upper limbs. RESULTS:Findings include low-amplitude medial antebrachial cutaneous (MACN) sensory nerve action potentials (SNAPs) and median compound muscle action potentials (CMAPs) and chronic denervation changes in the bilateral abductor pollicis brevis (APB) muscles on needle electrode examination (NEE), indicating axonal loss in the bilateral T1 distribution. CONCLUSIONS:The EDx data are in keeping with lesions involving bilateral T1 anterior primary rami (APR). Potential sites of compromise of the T1 APR are discussed. Further study of the effect of treatment for macromastia on the clinical and EDx findings is proposed.
