Abstract
Introduction Hidradenitis suppurativa (HS) is a chronic, debilitating, recurrent, auto-inflammatory
disease of the pilosebaceous units of the skin. The axillary region is the most affected
anatomical site and its reconstructive options include skin grafts, local random plasties,
regional axial flaps, and regional perforator flaps. The main aim of this systematic
review is to identify the best surgical technique for axillary reconstruction in the
context of HS, in terms of efficacy and safety.
Methods We adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses
(PRISMA) throughout the whole review protocol build-up. The literature search was
performed using MEDLINE, Embase, and Cochrane library databases, updated to March
2021. Quality was assessed for each study, through the National Institutes of Health
Quality Assessment Tool.
Results A total of 23 studies were included in the final analysis. We reviewed a total of
394 axillary reconstructions in 313 patients affected by HS Hurley Stage II or III.
Skin grafts were associated with the highest overall complication rate (37%), and
highest rate of reconstruction failure (22%). Between thoraco-dorsal artery perforator
flap, posterior arm flap, and parascapular flap, the latter showed fewer total complications,
recurrences, and failures.
Conclusion Regional axial flaps should be considered as the best surgical approach in the management
of advanced HS. The parascapular flap emerges as the most effective and safest option
for axillary reconstruction. Local random flaps might be considered only for selected
minor excisions, due to the higher risk of recurrence. The use of skin grafts for
axillary reconstruction is discouraged.
