Drum Dermatome — Padgett-Hood
The Padgett-Hood dermatome is a drum-type skin-grafting instrument that represents the commercially refined version of the original Padgett drum dermatome (1939), produced by Hood Laboratories. It was the first instrument capable of harvesting calibrated, uniform-thickness split-thickness skin grafts — a transformational advance over the freehand Humby knife and the antecedent Reverdin / Ollier-Thiersch razor-blade era. Largely supplanted by powered oscillating-blade dermatomes for routine STSG harvest, the Padgett-Hood retains defined contemporary niches in harvesting grafts from excised tissue specimens, very thick STSGs for joint surfaces, dermal grafts, and de-epithelialization of free flaps.[1][2]
Historical Context
- Earl Calvin Padgett (University of Kansas Medical Center plastic surgery chair, 1893–1946) imagined the device with help from George J. Hood (engineer at the University of Kansas).
- Hood applied for the first patent in 1938; Padgett displayed a working model at a medical meeting in 1939.
- Based on the adhesion-traction principle — the drum holds the skin in place by adhesive contact while a calibrated blade shaves the graft.
- The Hood modification (Hood Laboratories) became the standard commercially available version, hence the combined name Padgett-Hood.[1]
- A founding member of the American Board of Plastic Surgery called it "the greatest contribution in many decades to the technique of skin grafting."
Design
- Half-cylindrical metal drum that rotates as it is advanced across the donor site
- Dermatome adhesive cement applied to the drum surface adheres the skin to the drum during rotation — provides the counter-traction necessary for a clean even cut[3]
- Calibrated blade mounted alongside the drum with an adjustable gap between blade and drum surface
- Thickness range typically 12/1,000–26/1,000 inches (0.012–0.026") depending on clinical need[2][4]
- Manual operation — no power source
Mechanism
The surgeon rolls the drum across the prepared lubricated donor site; the adhesive pulls the skin onto the drum, and the blade shaves a uniform sheet at the set thickness. Brody 1979 published specific suggestions to facilitate use and care, particularly the maintenance of the drum and blade assembly that determines long-term reliability.[5]
Reconstructive Use Cases — Modern Niche Applications
The drum-with-adhesive design has surgical advantages that no powered dermatome can match, which keep the Padgett-Hood relevant for specific reconstructive scenarios:
1. Reused-Skin-Graft Technique (Donor-Site-Sparing)
The single most distinctive contemporary application. Kuo & Ohara 2003 described the Padgett-Hood specifically for the "reused skin graft" technique in chronic gluteal hidradenitis suppurativa:[2]
- After wide en-bloc excision of affected skin
- The Padgett-Hood harvested STSGs from the excised skin specimen itself (set at 12–20/1,000")
- Grafts then meshed 1.5× and applied to the surgical defect
- No separate donor site needed
- No recurrence during 8–36 mo follow-up
The technique exploits the unique drum-adhesive mechanic: the adhesive holds the excised tissue firmly against the drum even when it is not attached to a living donor site — something no powered dermatome can replicate.
GU translation: directly applicable to groin / perineal / scrotal hidradenitis excision and any large excisional reconstruction where reusing the excised skin would avoid a separate donor.
2. Very Thick STSGs for Mobile / Joint Surfaces
Tang 2010 described the Padgett dermatome for harvesting very thick STSGs (0.024–0.026") for mobile burned-limb surfaces, where thicker grafts minimize joint contracture. Simple and time-saving in his series.[4]
GU translation: applicable when thick-graft coverage is needed over a mobile area in genital / perineal reconstruction.
3. Dermal Grafts
Schaffer 1976 described the drum dermatome technique for obtaining dermal grafts with results equivalent to other mechanical methods.[6]
4. Radial Forearm Free-Flap Donor-Site Coverage
Jaquet 2012 used the Padgett for 0.35–0.45 mm STSGs from the thigh to cover RFFF donor sites in head-and-neck reconstruction — translation to the phalloplasty RFFF donor site is direct.[7]
5. De-Epithelialization of Buried Flaps
The same principle that drives the Padgett electric dermatome's free-flap de-epithelialization use applies to the drum: precise epidermal removal without damaging dermal blood supply. Relevant to buried phalloplasty flaps and any reconstructive context where a buried flap surface needs to be covered by recipient skin.
Advantages
- Excellent graft thickness uniformity — the fixed blade-to-drum gap is highly consistent, superior to freehand
- Capable of very thick grafts (up to 0.026") — critical for mobile / joint surfaces[4]
- Harvesting from excised tissue — the adhesive-drum mechanic uniquely supports the reused-graft technique[2]
- No power source required — fully manual
- Large continuous sheet the size of the drum surface
Limitations
- Adhesive cement requirement — proper application is essential and adds setup complexity[3]
- Technically demanding — drum pressure, rotation speed, adhesive application all require experience
- Slower than powered dermatomes for large-area routine harvest
- Maintenance burden — careful care of the drum and blade assembly required to maintain performance[5]
- Largely supplanted for routine harvesting by powered oscillating-blade dermatomes (Zimmer, Padgett electric)
