- Middle ear adenoma with neuroendocrine differentiation: relate of two cases and literature review(2013) BITTENCOURT, Aline Gomes; TSUJI, Robinson Koji; CABRAL JUNIOR, Francisco; PEREIRA, Larissa Vilela; FONSECA, Anna Carolina de Oliveira; ALVES, Venâncio; BENTO, Ricardo FerreiraINTRODUCTION: Adenomas with neuroendocrine differentiation are defined as neuroendocrine neoplasms, and they are rarely found in the head and neck. OBJECTIVE: To describe two cases of a middle ear adenoma with neuroendocrine differentiation, with a literature review. CASE REPORT: Patient 1 was a 41-year-old woman who presented with a 3-year history of left aural fullness associated with ipsilateral ""hammer beating"" tinnitus. Patient 2 was a 41-year-old male who presented with unilateral conductive hearing loss. CONCLUSION: Adenoma with neuroendocrine differentiation of the middle ear is a rare entity, but it should be considered in patients with tinnitus, aural fullness, and a retrotympanic mass and remembered as a diferential diagnosis of tympanic paraganglioma.

- Cochlear Implantation and Single-sided Deafness: A Systematic Review of the Literature(2016) CABRAL JUNIOR, Francisco; PINNA, Mariana Hausen; ALVES, Ricardo Dourado; MALERBI, Andrea Felice dos Santos; BENTO, Ricardo FerreiraIntroduction Current data show that binaural hearing is superior to unilateral hearing, specifically in the understanding of speech in noisy environments. Furthermore, unilateral hearing reduce oné s ability to localize sound. Objectives This study provides a systematic review of recent studies to evaluate the outcomes of cochlear implantation in patients with single-sided deafness (SSD) with regards to speech discrimination, sound localization and tinnitus suppression. Data Synthesis We performed a search in the PubMed, Cochrane Library and Lilacs databases to assess studies related to cochlear implantation in patients with unilateral deafness. After critical appraisal, eleven studies were selected for data extraction and analysis of demographic, study design and outcome data. Conclusion Although some studies have shown encouraging results on cochlear implantation and SSD, all fail to provide a high level of evidence. Larger studies are necessary to define the tangible benefits of cochlear implantation in patients with SSD.

- Mastoid Obliteration with Autologous Bone in Mastoidectomy Canal Wall Down Surgery: a Literature Overview(2016) ALVES, Ricardo Dourado; CABRAL JUNIOR, Francisco; FONSECA, Anna Carolina de Oliveira; BENTO, Ricardo FerreiraIntroduction The objectives of mastoidectomy in cholesteatoma are a disease-free and dry ear, the prevention of recurrent disease, and the maintenance of hearing or the possibility to reconstruct an affected hearing mechanism. Canal wall down mastoidectomy has been traditionally used to achieve those goals with greater or lesser degrees of success. However, canal wall down is an aggressive approach, as it involves creating an open cavity and changing the anatomy and physiology of themiddle ear andmastoid. A canal wall up technique eliminates the need to destroy the middle ear and mastoid, but is associated with a higher rate of residual cholesteatoma. The obliteration technics arise as an effort to avoid the disadvantages of both techniques. Objectives Evaluate the effectiveness of the mastoid obliteration with autologous bone in mastoidectomy surgery with canal wall down for chronic otitis, with or without cholesteatoma. Data Synthesis We analyzed nine studies of case series comprehending similar surgery techniques on 1017 total cases of operated ears in both adults and children, with at least 12 months follow-up. Conclusion Mastoid Obliteration with autologous bone has been utilized for many years to present date, and it seems to be safe, low-cost, with low recurrence rates - similar to traditional canal wall down procedures and with greater water resistance and quality of life improvements.
