RESUMO

OBJECTIVE: To compare the dynamic viscosity of superficial layer of temporalis fascia with that of other biological tissues traditionally used for vocal fold implants to treat vocal fold rigidity. STUDY DESIGN: Experimental. METHOD: Measurement of dynamic viscosity of samples of superficial layer of temporalis fascia, deep layer of temporalis fascia and abdominal fat of 12 cadavers are performed. RESULTS: Dynamic viscosity values of the different samples are presented in the following increasing order: superficial layer of temporalis fascia, deep layer of temporalis fascia and abdominal fat. There is statistical difference among all the samples. CONCLUSION: Dynamic viscosity of superficial layer of temporalis fascia is lower than the ones of deep layer of temporalis fascia and abdominal fat.
