Nerve Coaptation in LTP Flap Breast Reconstruction

October 19, 2023 updated by: Rene van der Hulst, Maastricht University Medical Center

Sensory Recovery of the Breast Following Innervated and Non-innervated Lateral Thigh Perforator (LTP) Flap Breast Reconstructions

The sensory recovery of the breast remains an undervalued aspect of breast reconstruction and surgical reinnervation is not regarded as a priority by most reconstructive surgeons. A prospective study was conducted of all patients who underwent either innervated or non-innervated lateral thigh perforator (LTP) flap breast reconstruction in Maastricht University Medical Center and returned for follow-up between February 2016 and April 2019. Semmes-Weinstein monofilaments were used for sensory testing of the breast.

Study Population

In this prospective study, patients who underwent an innervated or non-innervated LTP flap breast reconstruction between December 2014 and August 2018 at Maastricht University Medical Center in the Netherlands were included if they returned for follow-up between February 2016 and April 2019.

Description

Inclusion Criteria:

  • Female patients 18 years or older
  • Unilateral or bilateral LTP flap breast reconstruction
  • Returned for follow-up between February 2016 and April 2019
  • Informed consent

Exclusion Criteria:

  • In case of a total flap loss
  • Flaps that required a take-back
  • Follow-up less than six months postoperatively

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Innervated LTP flaps
Patients in this group underwent immediate or delayed, unilateral or bilateral lateral thigh perforator (LTP) flap breast reconstruction with additional sensory nerve coaptation.
Procedure: Sensory nerve coaptation
A recipient sensory nerve branch of the lateral cutaneous femoral nerve (LCFN) 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.
Other Names:
  • Neurotization
  • Reinnervation
Non-innervated LTP flaps
Patients in this group underwent immediate or delayed, unilateral or bilateral lateral thigh perforator (LTP) flap breast reconstruction without sensory nerve coaptation.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The sensory recovery of the reconstructed breast as assessed by Semmes-Weinstein monofilaments
Time Frame: Through study completion up to 27 months postoperatively
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.
Through study completion up to 27 months postoperatively
