Sensory Nerve Coaptation in DIEP Flap Breast Reconstruction

Maastricht University Medical Center126 enrolled

Overview

Restoring the sensation of the breast becomes increasingly recognized as a critical part of autologous breast reconstruction. A prospective study was conducted of all patients who underwent either innervated or non-innervated deep inferior epigastric perforator (DIEP) flap breast reconstruction in Maastricht University Medical Center between August 2016 and August 2018 and who returned between for a follow-up visit between the start of the study and August 2019. Semmes-Weinstein monofilaments were used for sensory testing of the breast.

Interventions

Sensory nerve coaptationPROCEDURE

A recipient sensory nerve branch of the 11th-12th intercostal nerve was reattached to a donor nerve in the chest area. The anterior cutaneous branch of the second or third intercostal nerve was used as the donor nerve. Direct, end-to-end nerve coaptation was performed.

Outcomes

Primary Outcomes

Mean monofilament value as a measure for the sensory recovery of the reconstructed breast

The sensory recovery of the breast to touch was tested at different follow-up moments after the initial surgery. Semmes-Weinstein monofilaments were used for sensory testing. Nine areas of the breast, indicating native skin and flap skin, were tested. Mean monofilament values were calculated for each area and compared between groups.

Time frame: Through study completion up to 36 months postoperatively

Secondary Outcomes

Mean monofilament value as a measure for the sensory recovery of the reconstructed breast

The sensory recovery of the donor site to touch was tested at different follow-up moments after the initial surgery. Semmes-Weinstein monofilaments were used for sensory testing. Four areas of the donor site were tested, two areas above and two areas below the scar. Mean monofilament values were calculated for the total donor site and compared between groups.

Time frame: Through study completion up to 36 months postoperatively
