Answer:
The Sistrunk procedure (1918) is an ablative procedure like the Charles procedure (see next question), after which the resected areas are covered with skin flaps.
The Homans-Miller procedure (1936) is a modification using thin skin flaps to cover the resected area. Using particularly thin skin flaps, Miller was able to achieve an aesthetically pleasing result. Miller elevates an anterior and posterior flap from both a medial and lateral incision, raising flaps approximately 1 cm thick. The underlying lymphedematous tissue is excised down to muscle fascia. The skin flaps are trimmed and sutured into position. Good aesthetic and functional results are obtained with this procedure, which is now considered the standard ablative approach used in the treatment of forearm and upper extremity lymphedema. However, occasionally second or even third operations are required to obtain the maximum benefit.
The Thompson dermal flap procedure attempts to merge dermal lymphatics with the deep system by burying a deepithelialized dermal flap. A long flap similar to that used in the Miller procedure is raised and instead of the excess tissue being excised it is deepithelialized and buried, thinking that communications between the superficial and deeper tissue will develop, although there has never been documentation of this, as any benefit with this procedure could well be solely due to the excision of tissue. In addition, the viability of this long random pattern flap is questionable, and the procedure as a whole has not become particularly popular.
