Bilobed propeller parascapular–scapular flap for reconstruction of axillary defects following wide excision of advanced hidradenitis suppurativa
摘要
Radical wide excision is the definitive surgical treatment for advanced (Hurley stage III) axillary hidradenitis suppurativa (HS). However, reconstructing the resulting large and asymmetric defects remains a significant challenge. While single-lobe propeller flaps are effective, they may be insufficient for extensive defects. We aimed to evaluate the feasibility and applicablility of a bilobed propeller parascapular–scapular flap configuration for reconstructing these complex wounds.
MethodsWe retrospectively reviewed eight male patients (mean age: 38 years) who underwent axillary reconstruction using a bilobed propeller flap following radical excision between 2021 and 2025. All patients presented with Hurley stage III disease. The flap design integrated tissue territories supplied by both the transverse and descending branches of the circumflex scapular artery on a single vascular axis. Demographic data, flap dimensions, complications, and functional outcomes were analyzed.
ResultsThe mean flap area was 166 (range: 116–307 ), with a mean body mass index (BMI) of 29.9. All donor sites were closed primarily. At a mean follow-up of 11 months, all flaps survived completely (100% survival rate), and no disease recurrence was observed. Minor wound dehiscence occurred in one diabetic patient (12.5%) and was managed conservatively. Functional shoulder mobility was fully preserved in all patients, with no restrictive contractures reported.
ConclusionsThe bilobed propeller parascapular–scapular flap appears to be a feasible technical refinement for the management of extensive axillary HS. By utilizing two distinct vascular territories on a single pedicle, this design provides adequate coverage with low observed donor-site morbidity and preserved functional outcomes.
