Assessment of Chronological Volume Changes in Radial Forearm Free Flaps for Tongue Cancer.

ABSTRACT

OBJECTIVE: The radial forearm free flap (RFFF) is a commonly used free flap for tongue cancer. Postoperative changes in the volume of free flap are known to influence the functional restoration of the resected tongue. This study aimed to estimate chronological volume changes in RFFFs for tongue cancer and to determine the clinical factors affecting these changes. METHODS: Clinical data for 19 patients who underwent RFFF reconstruction for tongue cancer between May 2004 and September 2013 were retrospectively reviewed. The flap volume was measured 3, 6, 12, 24, and 36 months after surgery using CT and the Picture Archiving and Communication System software. RESULTS: Relative to volumes at 3 months, median flap volumes decreased to 98.55, 70.16, 62.86, and 58.84% at 6, 12, 24, and 36 months, respectively. None of the evaluated parameters were correlated with volume changes. CONCLUSIONS: Over time, the volume of RFFF in the tongue decreased. Considering this, free flap reconstruction should be carried out in tongue cancer surgery.
