Table 1. Definition of terms and techniques for sensory restoration and preservation.

Term/technique	Definition	Technical pearls/details
Neurotized flap reconstruction	Coaptation of flap donor nerve to recipient intercostal nerve using direct repair, nerve conduit, or nerve allograft	Most frequently done with DIEP flap reconstruction; anterior branch of third intercostal nerve typically preferred to lateral given proximity to donor vessels
NAC neurotization	Targeted reinnervation of the NAC from the lateral intercostal nerve using either direct repair or repair with nerve allograft or autograft	Connector-assisted repair can be done if a subareolar nerve target can be identified; if not, coaptation to the dermis can be performed
Sensation-preserving mastectomy	Combined approach of nerve reconstruction/NAC neurotization and nerve preservation of lateral and medial intercostal nerves that can be safely preserved from an oncologic standpoint	Requires team approach of breast oncologic and reconstructive surgeons; can be performed with any type of reconstruction and aesthetic flat closure

DIEP, deep inferior epigastric perforator; NAC, nipple-areolar complex.
