Free flaps in the elderly.

Microsurgical transfer of tissue has become a primary tool of the reconstructive surgeon. The elderly, as a growing segment of our society, are requiring free-tissue transfers in proportion to their numbers. To investigate the potential morbidity of free-tissue transfers in the elderly, we studied consecutive populations of 31 patients above the age of 65 years and 90 patients below the age of 65 years. Complication rates were 65 and 49 percent, respectively. Premorbid medical conditions were present in 87 percent of patients 65 years and older and in 72 percent of those under 65 years. Medically related complications in free-tissue transfers, previously unreported in the literature, were 35 percent in the elderly group and 10 percent in the younger group. Wound-healing complications were seen in equal proportions between groups. The rates of wound and medically related complications observed in the elderly group were nearly double those observed in the younger group; however, after correction for the presence of preexisting medical conditions, no significant differences were seen between the two groups. These observations suggest that age alone is not a variable in risk for free-tissue transfers. Elective microsurgery can be performed in the elderly patient with a high expectation of success.
