RESUMO
Objective: To explore the social and clinical factors that predict audiometric outcomes in patients undergoing ossicular chain reconstruction. Methods: A retrospective analytical cohort study was conducted, including patients 18 years of age or older with a history of chronic otitis media (COM) and/or any of its complications, who underwent ossicular chain reconstruction with Partial Ossicular Replacement Prosthesis (PORP) or Total Ossicular Replacement Prosthesis (TORP), at Hospital San José and Hospital infantile Universitario de San José between 2012 and 2020. We excluded patients with ossicular chain malformations and those with incomplete information. Information about sociodemographic and clinical factors was collected. Additionally, the surgery findings information was analyzed using the Ossiculoplasty outcome parameter staging ( OOPS) index. Results: A total of 35 adult patients who underwent ossicular chain reconstruction were retrospectively studied. An improvement was evidenced in the Preoperative Pure-Tone Average (PTA) and postoperative PTA (p-value=0.036), as well as in the pre and postoperative air-bone gap (ABG) (p-value < 0.01). A moderate correlation coefficient was found between the OOPS index and the postoperative PTA (p= 0.429), and between the OOPS index and the postoperative (ABG) (p= 0.653). Conclusion: We found that a higher OOPS score is correlated with worse hearing outcomes postoperatively, and there was no association between the demographic or pathologic factors with a worse postoperative hearing outcome. Therefore, OOPS index can predict audiometric outcomes in patients undergoing ossicular chain reconstruction in a developing country, regardless of the demographic or pathologic factors.
Objetivo: Evaluar los factores sociales y clínicos que predicen los desenlaces audiométricos en pacientes llevados a reconstrucción de cadena osicular en un país envía de desarrollo. Métodos: Se realizo un estudio de cohorte analítico retrospectivo donde se incluyeron pacientes mayores de 18 años, con antecedente de otitis media crónica y/o alguna complicación/secuela de esta, que fueron llevados a reconstrucción de la cadena osicular con prótesis PORP - TORP de la Fundación Universitaria de Ciencias de la Salud entre el año 2012 y 2020, se excluyeron pacientes con malformaciones de la cadena osicular y aquellos con informacion incompleta de su historia clinica y quirurgica. Resultados: La población estudiada fue 35 pacientes, en los cuales se compararon variables demográficas, antecedentes de rinitis o tabaquismo activo, parámetros audiológicos pre y postoperatorios, y hallazgos intraquirurgicos. Se evidenció una diferencia estadísticamente significativa entre el promedio tonal auditivo (PTA) preoperatorio y el PTA postoperatorio (p-valor=0.036), así como en el gap aéreo- oseo pre y post operatorio ( p-valor < 0.01). Se reportó un coeficiente de correlación moderado entre el índice OOPS y el PTA post operatorio (p = 0.429), y entre el índice OOPS y el gap aéreo óseo post operatorio (p = 0.653), lo que indica que a mayor puntaje en el índice OOPS peores desenlaces auditivos. Conclusión: En este estudio un mayor puntaje en el índice OOPS se correlacionó con peores desenlaces auditivos. No se evidenció correlación entre los factores demográficos u otras comorbilidades descritas y un peor desenlace auditivo post operatorio. Aunque se obtuvo un GAO postoperatorio ≤20dB en el 48.5% de los pacientes, se observó una disminución en el GAO estadísticamente significativo.

Abstract Introduction Inactive squamosal disease is unique for having a conflicting treatment protocol, with an age-old debate between early surgical intervention or keeping patients in a long-term follow-up. The shifting paradigm is early intervention to prevent further progress into active disease and improve hearing outcome in its nascent stage. Objective To evaluate recurrence and hearing outcome in cases of inactive squamosal disease after cartilage strengthening tympanoplasty. Methods The study was conducted on 50 patients with inactive squamosal disease. Detailed examination was done to grade the retraction. All patients underwent autologous conchal cartilage tympanomastoidectomy with temporalis fascia grafting. Recurrence and hearing evaluations were done by pure tone audiogram at regular intervals for one year. Results Hearing loss was the most common presenting symptom. Isolated pars tensa retractions were more common (54%) than pars flaccida (12%), or those involving both (34%). Ossicular status was normal in only 14% of the cases, and the most common ossicular damage was to the lenticular process of the incus (52%). Three of the patients (6%) had residual perforation at the 3rd month of follow-up. Subjective improvement in hearing was reported by 42% patients. Hearing improvement greater than 10 dB was found in 24 patients (48%). Air-bone gap reduced from 25.16 ± 8.15 dB preoperatively to 12.90 ± 6.20 at 1 year of follow-up. Recurrence was seen in three patients (6%). Conclusion Early intervention by cartilage strengthening of weakened tympanic membrane and ossicular reconstruction not only offers better hearing results, but also prevents progress to active disease.

RESUMO
RESUMO Objetivos Analisar as publicações científicas sobre audição em indivíduos com osteogênese imperfeita. Estratégias de pesquisa Trata-se de revisão sistemática de literatura. Foram selecionados os descritores Hearing OR Hearing Loss AND Osteogenesis Imperfecta. Duas revisoras consultaram as bases de dados Cochrane Library, PubMed, LILACS, Scopus e Embase. Critérios de seleção utilizaram-se os Descritores em Ciências da Saúde, não sendo delimitado período de publicação dos estudos. Foram critérios de inclusão estudos de coorte, seguimento, transversais, casos controle e em idioma inglês. Foram critérios de exclusão artigos editoriais, relatos/séries de casos, resumos de eventos e estudos conduzidos em animais. Os estudos selecionados foram analisados pela Iniciativa STROBE e pelo Sistema GRADE. Resultados Dos 652 estudos obtidos, foram selecionados 16. A perda auditiva do tipo condutiva foi o tipo mais comum na população com osteogênese imperfeita (OI) e seu início ocorre por volta da segunda década de vida. A definição e a classificação para aferição de perda auditiva, nas publicações com a população com osteogênese imperfeita, apresentaram discordância entre os estudos. Conclusão Esta revisão respondeu às perguntas a que se propôs, constatando que as alterações audiológicas encontradas em pacientes com OI são do tipo condutivo, neurossensorial e misto. Alterações condutivas são mais comuns em pacientes mais jovens e alterações neurossensoriais, em pacientes mais velhos. A Iniciativa STROBE apontou itens descritos de forma parcial e o Sistema GRADE concluiu que os estudos apresentaram alguma falha metodológica.
ABSTRACT Purpose To analyze scientific publications on the hearing issue of patients with osteogenesis imperfecta. Reserch strategy This study is a systematic literature review. The following descriptors were selected "Hearing" OR "Hearing Loss" AND "Osteogenesis Imperfecta". Two reviewers searched the Cochrane Library, Pubmed, Latin American and Caribbean Health Sciences Literature, Scopus and Embase databases. Selection criteria Descriptors in Health Sciences were used and the publication period of studies was not limited. Inclusion criteria were cohort, follow-up, cross-sectional, and control studies in English language. Exclusion criteria were editorial articles, case reports, case summaries, and animal studies. Selected studies were analyzed by the STROBE Initiative and the GRADE System. Results Of the 652 studies, 16 were selected. Conductive hearing loss is the most common type in the osteogenesis imperfecta (OI) population and its onset is around the second decade of life. Definition and classification for hearing loss measurement in publications with the osteogenesis imperfecta population present disparities among studies. Conclusion This review met the objectives proposed, concluding that audiological alterations found in OI patients are of conductive, sensorineural and mixed types; conductive alterations are more common in younger patients and sensorineural alterations in older ones. The STROBE initiative partially pointed out described items and the GRADE system concluded that studies present some methodological failure.

OBJECTIVE: To determine whether patients with simple chronic otitis media and incomplete ossicular discontinuity should undergo ossicular reconstruction. DESIGN: Prospective, randomised surgical trial comparing no intervention with incus interposition over a 5-year period. SETTING: Tertiary referral hospital. PARTICIPANTS: Seventy-six participants with simple chronic otitis media and erosion of the long process of the incus but apparent good transmission throughout the ossicular chain as tested intra-operatively. Forty-four patients had partial erosion of the incus but still bony contact with the stapes head (Group A-Type I), and 32 had mainly connective tissue binding the incus and stapes (Group B-Type II). Each of these groups was randomised to either leaving the ossicular chain as it was (A1 and B1) or performing an incus interposition (A2 and B2). MAIN OUTCOME MEASURES: Average postoperative air-bone gap and the degree of ABG closure. A postoperative air-bone gap under 20 dB was considered a successful result. RESULTS: In group A, there was no significant difference between no intervention and incus interposition. In group B, patients in the no reconstruction subgroup had a significantly worse hearing result than the incus interposition subgroup (postoperative air-bone gap of 27.5 dB and 31% closure within 20 dB vs 15 dB and 75% closure). CONCLUSIONS: For Type I patients, the postoperative hearing results were similar for the reconstruction and no reconstruction groups. For Type II patients, the results clearly favour reconstruction.

Abstract Introduction Chronic otitis media can cause multiple middle ear pathogeneses. The surgeon should be aware of relation between ossicular chain erosion and other destructions because of the possibility of complications. Objective This study aimed to investigate the rates of ossicular erosion in cases of patients with and without facial nerve canal destruction, who had undergone mastoidectomy due to chronic otitis media with or without cholesteatoma. Methods We retrospectively analyzed three hundred twenty-seven patients who had undergone tympanomastoidectomy between April 2008 and February 2014. We documented the types of mastoidectomy (canal wall up, canal wall down, and radical mastoidectomy), erosion of themalleus, incus and stapes, and the destruction of facial and lateral semi-circular canal. Results Out of the 327 patients, 147 were women (44.95%) and 180 were men (55.04%) with a mean age 50.8 ± 13 years (range 8-72 years). 245 of the 327 patients (75.22%) had been operated with the diagnosis of chronic otitis media with cholesteatoma. FNCD was present in 62 of the 327 patients (18.96%) and 49 of these 62 (79.03%) patients had chronic otitis media with cholesteatoma. The correlation between the presence of FNCD with LSCC destruction and stapes erosion in chronic otitis media with cholesteatoma is statistically significant (p < 0.05). Conclusion Although incus is the most common of destructed ossicles in chronic otitis media, facial canal destruction is more closely related to stapes erosion.

Objetivo: describir los hallazgos imagenológicos e identificar los diferentes mecanismos etiológicos de la luxación incudomaleolar. Metodología: Se realizó una revisión bibliográfica en PubMed de los artículos publicados hasta febrero de 2015 con las palabras claves: Ear ossicles; Temporal bone; Bone; Fractures; Dislocation; Conductive hearing loss. Se encontraron 352 artículos de los cuales se seleccionaron aquellos donde se menciona la luxación incudomaleolar. Resultados: Se revisaron los abstracts de los 352 artículos, encontrando 20 donde mencionaban la definición, la epidemiología, la clínica y el diagnóstico imagenológico de la luxación incudomaleolar, los cuales fueron utilizados para la elaboración de esta revisión. Conclusiones: La principal causa de daño en la cadena de huesecillos es la fractura del hueso temporal y dentro de las patologías que puede generar está la luxación incudomaleolar, por lo que es de interés el diagnóstico temprano a todos los pacientes con sospecha clínica para llegar a prevenir complicaciones. La revisión de la literatura permite concluir que la técnica más eficaz para la identificación de la luxación Incudomaleolar es la tomografía computarizada, la cual requiere una adecuada identificación en los diferentes cortes multiplanares, o en las reconstrucciones 3D para poder diagnosticarla.
Introduction: This research emphasizes in the incudomallear dislocation. Although it is rare, it is a disease with great clinical relevance due to the short and long term involvement of patients hearing so that it affects their quality of life, so it is very important a timely diagnosis for an early and effective treatment. Objective: To describe the imaging findings and identify the different etiologic mechanisms of incudomallear dislocation. Methodology: A literature review was carried out in PubMed about articles published until February 2015 with the keywords: "Ear ossicles"; "Temporal bone"; "Bone," "Fractures"; "Dislocation"; "Conductive hearing loss" finding 352 articles and selecting those that mentioned the incudomallear dislocation. Results: The abstracts of 352 articles were examined and 20 of them mentioned the definition, epidemiology, clinical and imaging diagnosis of incudomallear dislocation, and they were used to prepare this research. Conclusions: The main cause of damage to the ossicles is the temporal bone fracture, and among the diseases that this can produce, there is the incudomallear dislocation, therefore it is of great interest a timely diagnosis to all patients with clinical suspicion to prevent complications. The literature review allows us to conclude that the most effective technique to identify the incudomallear dislocation is computed tomography, which requires proper identification in different multiplanar cuts, or 3D reconstructions to diagnose it.

Estapedotomias são realizadas atualmente com o auxílio de microscópios cirúrgicos. Entretanto, o uso do microscópio possui algumas limitações, podendo causar algumas complicações, como lesão no nervo corda do tímpano. Há poucos casos e nenhuma série publicada sobre a utilização de endoscópios nasossinusais na realização de estapedotomias. OBJETIVOS: a) Investigar o uso do endoscópio nasossinusal em estapedotomias, com foco na visualização de estruturas importantes. b) Mostrar os resultados iniciais, discutindo as possíveis vantagens e desvantagens deste instrumento. METODOLOGIA: 15 pacientes com otosclerose foram selecionados para realizar estapedotomias em 2010. Os dados e vídeo cirúrgico foram analisados retrospectivamente (estudo de série de casos). As condições anatômicas do nicho da janela oval e passos cirúrgicos foram descritos para avaliar possíveis benefícios do procedimento endoscópico. RESULTADOS: As cirurgias foram realizadas exclusivamente com endoscópios e todas as estruturas com relevância anatômica, visualizadas sem maiores dificuldades. Nenhuma complicação foi observada e 14 dos 15 pacientes referiram melhora auditiva, confirmada com exames audiológicos pós-operatórios. CONCLUSÃO: Estapedotomias totalmente endoscópicas são tecnicamente viáveis, seguras e promissoras. Nesta pequena série as principais vantagens foram: praticamente nenhum trauma no nervo corda do tímpano e excelente campo de visão. As desvantagens foram falta de visão estereoscópica, trabalho unimanual e curva de aprendizado.
Stapedotomies are perfomed with the aid of surgical microscopes. However, the microscope has some limitations and may cause complications such as damage to the chorda tympani nerve. There are just a few cases and no series published on the use of sino-nasal endoscopes in stapedotomies. OBJECTIVES: a) To investigate the feasibility of using sino-nasal endoscopes in stapedotomies, focusing on the visualization of important structures. b) To show initial results, discuss possible advantages and disadvantages of this instrument. METHODS: 15 patients with otosclerosis were selected to undergo stapedotomies in 2010. The data and surgery videos were analyzed retrospectively (study case series). The anatomical conditions of the oval window niche and surgical steps were described and used to assess possible benefits of such procedures. RESULTS: The surgeries were performed with endoscopes only and all relevant anatomical structures were visualized without difficulty. No complications were observed and 14 of the 15 patients reported improvement of their hearing, confirmed by postoperative audiological tests. CONCLUSION: Totally endoscopic stapes surgeries are technically feasible, safe and promising. In this small series, the main advantages were: virtually no trauma to the chorda tympani nerve and excellent vision. The disadvantages were the lack of stereoscopic vision, having to work with one hand only and the learning curve.
