Dynamic correction of intractable vaginal prolapse.

Recurrent vaginal prolapse can be very difficult to correct by simple methods. This is especially true when adequate muscle support is lacking. Scar tissues will simply not support the vagina under constant pressure, and the prolapse recurs. A new technique of diminishing vaginal size, correcting the prolapse, and then supporting the vaginal wall dynamically with both innervated gracilis muscles is described with a successful two-year follow-up.

Minimally invasive technic for construction of a cervical esophageal conduit.

Most technics of cervical esophageal reconstruction involve extensive surgical dissection with its attendant hazards. The present report describes a simplified technic that causes minimal trauma to the patient. A partially deepithelialized, superficial skin tube is created without elevation of flaps and joined to the existing stomata. The technic was succesfully used in a frail, five year old patient who had three previous unsuccessful attempts at colonic interposition for a tracheo esophageal fistula.

Experimental definition of independent myocutaneous vascular territories.

Experimental studies were undertaken in dogs to determine whether useful island myocutaneous flaps could be based on the gracilis, sartorius, biceps femoris, trapezius, or rectus abdominis muscles. Dissection and injection studies on these muscles were also undertaken in human cadavers to determine the contributions of these muscles to the blood supply of the overlying skin. In most instances it was considerable. The use of island myocutaneous flaps seems promising in many situations. Such transfers can be done in one operation, without delay procedures, and result usually in a better blood supply with the transfer of a thicker amount of tissue. Clinical research on such flaps in patients will be described in a subsequent paper.

Successful use of muscle flaps or myocutaneous flaps in patients with sickle cell disease.

Sickle cell disease presents an unusual challenge to the reconstructive surgeon. The interaction between the underlying hemoglobinopathy and the circulatory mechanics in pedicled flaps leads to a high incidence of flap necrosis in patients with this disease. We present 3 patients with sickle cell disease in whom the use of axial flaps allowed the repair of difficult reconstructive problems in one stage, without preoperative exchange transfusions. The rationale for this approach is discussed.

Clinical definition of independent myocutaneous vascular territories.

The use of myocutandous flaps can increase the possibilities for construction in many cases by bringing in new blood supply to avascular areas by furnishing additional bulk for filling defects or covering bone grafts or other deep repairs, and sometimes by making longer flaps viable. Also, the need for delay procedures is decreased and sometimes avoided. In this paper we define the vascular territories of 13 clinical myocutaneous flaps, and we describe possible uses of them. Three illustrative clinical cases are presented, in which repairs were done with these flaps. The future uses of these flaps challenge the imagination. Knowledge about them may significantly alter the traditional approaches to flap designs and repairs.
