Swallowing and speech function after intraoral soft tissue reconstruction with lateral upper arm free flap and radial...

Swallowing, speech, and morbidity were assessed postoperatively in 25 patients, 18 of whom had had intraoral defects reconstructed by lateral upper arm free flaps (LUFF) and 7 by radial forearm free flaps (RFFF). Video fluoroscopy was used to assess swallowing, the Freiburger audiometric test to assess speech; and measurement of arm circumference to assess donor site morbidity. A questionnaire was used to evaluate swallowing, speech, and donor site morbidity subjectively. The degree of impairment in swallowing depended on the site of resection. Anterior and posterior resections affected swallowing more than lateral resections. Anterior resection and the use of LUFFs reduced intelligibility. There was no significant difference in impairment between LUFF and RFFF. We conclude that the LUFFs are superior to RFFFs because they can be closed primary and the incidence of donor site morbidity is slight.
