Zusammenfassung:The purpose of this study was to determine whether prior radiotherapy had any effect on the development of postoperative complications in patients undergoing microvascular tissue transfers for reconstruction of head and neck cancer. A prospective database was used to review 354 consecutive patients who had a total of 368 free tissue transfers limited to the head and neck during the 4-year period from July 1988 to June 1992. Postoperative complications in 167 patients who received preoperative radiotherapy (XRT) were compared with those of 187 patients who did not undergo radiotherapy preoperatively (NR). No statistical differences in complications or flap loss between the two groups were noted using the χ 2 test or Fisher's exact test (p>0.2). Total flap loss occurred in 5.3% of the XRT group (9 of 169) and 5.0% of the NR patient group (10 of 199), and partial flap loss occurred in 4.1% of the irradiated patients and 2.5% of the nonirradiated patients. Major wound complications requiring additional surgery occurred in 16% of the XRT group and 11% of the NR group. Minor wound complications that did not require further surgery occurred in 21% of the irradiated patients and 18% of the nonirradiated patients. No significant difference in the timing or dose of preoperative radiation, previous neck dissection, or anastomotic type could be documented in failed versus successful flaps (two-tailed t-test p>0.80, and χ 2, p>0.2). Our results show that, in a large group of cancer patients undergoing free tissue transfers to the head and neck, prior radiotherapy or surgery did not predispose them to a higher rate of acute flap loss or wound complications than their nonirradiated cohorts.
