Background:

The higher life expectancy has increased the incidence of head and neck tumors in elder patients.

Objective:

the aim of this study was to evaluate the outcomes of free flap reconstructions after radical resection (FFRR) of head and neck tumors in patients aged 70 years or older.

Material and methods:

We analyzed a series of patients undergoing FFR due to head and neck tumors between 2000-2020. The patients were divided into two groups: G1: ≥ 70 years, and G2: < 70 years. The demographic, operative and postoperative variables and the risk factors for flap thrombosis in patients ≥ 70 years were analyzed.

Results:

A total of 178 patients were included, 61 in G1 and 117 in G2. Both groups were homogeneous regarding sex, BMI (body mass index), alcohol consumption, smoking habits, neoadjuvant treatment, and incidence of HPV (human papillomavirus). The incidence of ASA grade ≥ III was significantly higher in G1 vs. G2; (p: 0,005). In G1, 33 patients (54%) corresponded to cancer stage ≥ III vs. 99 (87%) in G2 (p: 0.001). Forty-two (69%) patients in G1 received adjuvant therapy vs. 94 (83%) in G2 (p = 0.02) and there were no differences in overall morbidity and mortality and in flap failure. Female sex was the only predictor of vascular flap thrombosis (p = 0.05).

Conclusion:

FFRR in head and neck tumors is feasible and safe in elderly patients, with morbidity and mortality rates similar to those of the general population.
