Partial breast reconstruction using chest wall perforator flaps (CWPF) is a recent option used by breast surgeons, mainly for lateral quadrant defects with a relatively large volume of excision. We report a single-centre experience of CWPF with surgery details, complications, re-excision, aesthetic and oncological outcomes. This was a prospective observational cohort study of patients who had undergone breast conservation surgery (BCS) plus CWPF reconstruction. All variables were recorded prospectively in the institutional database. A survey was done to analyse patient satisfaction at about 6 months after completion of radiotherapy. Forty patients had CWPF based reconstruction in 3 years. 57.5 % of patients had lateral intercostal artery perforator (LICAP) flap, 5% had lateral thoracic artery perforator (LTAP) flap, 27.5% had combined LICAP plus LTAP and 10% patients had anterior intercostal artery perforator (AICAP) flap. Tumour excision cavity defect was of the lateral quadrant in 82.5%, central quadrant in 10% and medial quadrant in 7.5% of patients. The margin was positive for five patients, out of which four required cavity shave and one had a mastectomy. One patient had complete flap loss, and two patients developed surgical site infection. 96% of patients were satisfied with the scar, and 88% were happy with the treated breast in comparison to the opposite breast. 92% were comfortable going out in public and felt that in retrospect their decision not to have a mastectomy was correct. With a median follow up of 18 (10, 22) months, one patient died, and four had recurrences. CWPF may be used for partial breast reconstruction in the small non-ptotic breast with excellent outcome and high patient satisfaction scores.
