Background: Axillary hidradenitis suppurativa (HS) can result in significant functional impairment in both personal and professional lives. Stage 3 HS requires radical surgical treatment. Flap reconstruction allows for faster healing and better functional and aesthetic outcomes. We compared the results of thoracodorsal artery perforator (TDAP) and propeller inner arm artery perforator (IAAP) flap reconstructions after radical surgical treatment of axillary HS.
Methods: We conducted a retrospective study that included 13 consecutive patients who underwent stage 3 axillary HS treatment between August 2015 and January 2023. Seven patients underwent reconstruction by islanded TDAP flaps, whereas six patients underwent reconstruction by propeller IAAP flaps, with one patient undergoing bilateral reconstruction. The data collected from the patient records included age, gender, smoking status, body mass index, comorbidities, operative time, defect size, flap size, hospital stay, and complications.
Results: Although not statistically significant (P = 0.1923), a higher rate of flap complications is reported here with propeller IAAP flaps (42.86 %), whereas islanded TDAP flaps had no flap complications (0%). We found a statistically significant difference in operative time (P = 0.0006), defect size (P = 0.0064), and flap size (P = 0.0012) between the two groups. All patients exhibited satisfactory functional and aesthetic outcomes. Fourteen flaps were performed in total; only one case exhibited recurrence (7.14%).
Conclusion: After radical surgical management, both islanded TDAP and propeller IAAP flap reconstructions offer excellent outcomes for stage 3 axillary HS. We strongly encourage our peers to consider performing perforator flaps over secondary healing for these patients with a major functional impairment.
