bookPart Paralisia Facial Periféria(2016) BENTO, Ricardo Ferreira; FONSECA, Anna Carolina de Oliveira; BRITO NETO, Rubens Vuono de- Decompression of the tympanic and labyrinthine segments of the facial nerve by middle cranial fossa approach: an anatomic study(2016) PEREIRA, Marcos Alexandre da Franca; BITTENCOURT, Aline Gomes; ANDRADE, Emerson Magno de; BENTO, Ricardo Ferreira; BRITO, Rubens dePeripheral facial palsy is characterized by the permanent or temporary interruption of facial muscle function. The middle cranial fossa (MCF) approach has been used to decompress the facial nerve (FN) when hearing needs to be preserved. In this work, we describe a technique for decompressing the FN through the MCF approach, which allows the direct exposure of the labyrinthine and entire tympanic segment of the FN, with preservation of inner ear function. Twenty cadavers heads were used in this study. The reference landmarks used were the middle meningeal artery, greater superficial petrosal nerve, arcuate eminence, inferior petrosal sinus and meatal plane following the petrous apex from its most anterior and medial portion. The tympanic segment of the FN presented, on average, a total length of 11 +/- 0.67 mm to the right and 11.5 +/- 0.60 mm to the left. The longitudinal lengths of the bone window in the tegmen tympani were 16.8 +/- 1.67 mm to the right and 16.8 +/- 1.20 mm to the left. The cross-sectional lengths of the bone window in the tegmen tympani were 5.5 +/- 1.20 mm and 5.0 +/- 1.75 mm to the right and left sides, respectively. The average value of the elliptical area formed by the longitudinal and transversal lengths of the bone window made in the tegmen tympani was 72.5 +/- 22.5 mm(2) to the right and 65.9 +/- 30.3 mm(2) to the left. The proposed technique can be used for the surgical decompression of the tympanic, labyrinthine and meatal segments of the FN through the MCF in addition to reducing the surgical time and the risk to patients.
- Vibrant Soundbridge and Bone Conduction Hearing Aid in Patients with Bilateral Malformation of External Ear(2016) MONDELLI, Maria Fernanda Capoani Garcia; MARIANO, Thais Cristina Barbosa; HONÓRIO, Heitor Marques; BRITO, Rubens Vuono deIntroduction Hearing loss is the most common clinical finding in patients with malformation of the external ear canal. Among the possibilities of treatment, there is the adaptation of hearing aids by bone conduction and the adaptation of implantable hearing aids. Objective To assess speech perception with the use of Vibrant Soundbridge (VBS - MED-EL, Innsbruck, Austria) associated with additional amplification in patients with bilateral craniofacial malformation. Method We evaluated 11 patients with bilateral malformation over 12 years with mixed hearing loss or bilateral conductive. They were using the Softband (Oticon Medical, Sweden) and bone conduction hearing aid in the ear opposite the one with the VSB.We performed the evaluation of speech perception using the Hearing in Noise Test. Results Participants were eight men and three women with a mean of 19.5 years. The signal / noise ratio presented significant results in patients fitted with VSB and bone conduction hearing aid. Conclusion The results of speech perception were significantly better with use of VBS combined with bone conduction hearing aids.
