ARAUJO, Marcos Miranda; MASSUDA, Eduardo Tanaka  and  HYPPOLITO, Miguel Angelo. Anatomical and functional evaluation of tympanoplasty using a transitory natural latex biomembrane implant from the rubber tree Hevea brasiliensis. Acta Cir. Bras. [online]. 2012, vol.27, n.8, pp. 566-571. ISSN 1678-2674.  http://dx.doi.org/10.1590/S0102-86502012000800009.

PURPOSE: To compare the role of transitory latex and sylastic^® implants in tympanoplasty on the closure of tympanic perforations. METHODS: A randomized double-blind prospective study was conducted on 107 patients with chronic otitis media submitted to underlay tympanoplasty and divided at random into three groups: control with no transitory implant, latex membrane group, and sylastic^® membrane group. RESULTS: Greater graft vascularization occurred in the latex membrane group (p<0.05). Good biocompatibility was obtained with the use of the latex and silicone implants, with no effect on the occurrence of infection, otorrhea or otorragy. CONCLUSION: The use of a transitory latex implant induced greater graft vascularization, with a biocompatible interaction with the tissue of the human tympanic membrane.
