Reliable reconstructive techniques are essential in the surgical treatment of head and neck cancer patients. Free flaps have often been used as reconstructive options of last resort in the head and neck because of the need for added technical skill, a longer operating time, and a perception of poor reliability. This study reviews our experience with 39 free flaps performed by the Otolaryngology-Head and Neck Surgery Service. For the first 17 cases, an interrupted anastomotic technique was used; a running technique was performed in the remaining 22 cases. The average total ischemic time (3.7 vs. 2.7 hours; p < 0.001) was significantly less with a running technique. There were 10 complications: 7 minor would problems, 1 death from aspiration without surgical wound/flap problem, and 2 cases requiring second flaps (1 flap necrosis, 1 fistula with healthy free flap). No statistical correlation was found between complications and ischemic time, suture technique, age, or hospital (five hospitals). Free flaps are reliable and may obviate the need for sacrifice of trunk muscles for wound closure (e.g., fascicocutaneous free flaps instead of myocutaneous flaps); therefore we recommend revascularized free flaps as the primary mode of reconstruction for head and neck defects.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D013524	Surgical Flaps	Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.
