Temporal bone 3D models – an innovative approach in otologic surgical training

Introduction: Temporal bone surgery requires high precision due to the complexity of its anatomy. Traditional surgical training with cadavers presents limitations such as scarcity of material, anatomical variability, and high costs. This study explores the use of personalized 3D models of the temporal bone from patients scheduled for otologic surgery as an innovative training tool.Materials and Methods: Persona...

Machine learning for automated otoscopic tympanic membrane assessment

Objectives: To develop and evaluate a deep learning model for automated classification of tympanic membrane and middle ear conditions using otoscopic images. Study Design: Retrospective. Materials and Methods: This study trained an EfficientNet-based convolutional neural network (CNN) on 618 labelled images across five categories: normal tympanic membrane (TM), acute otitis media (AOM), otitis media with effusi...

The utility of oropharyngeal pHmetry in the diagnosis and treatment of laryngop...

Introduction: Laryngopharyngeal reflux is a chronic illness with variable and unspecific symptoms, representing up to 10% of otolaryngology appointments. Its diagnosis and treatment are controversial, with high rates of treatment failure. Oropharyngeal pHmetry is an objective diagnosis method that measures both liquid and gaseous pH variations in the oropharynx, having previously demonstrated a higher diagnosis...

Merkel Cell Carcinoma - A clinical case report

Aim: To report a case of Merkel cell carcinoma in a patient who presented with a rapidly growing cervical mass. Background: Merkel cell carcinoma is a rare and aggressive cutaneous malignant tumor, with a high recurrence rate and propensity for metastasis. Our goal is to alert and raise awareness among otorhinolaryngologists about this entity, especially in the differential diagnosis of neck masses. Case descri...

Literacia da informação: luta contra a infoexclusão

A literacia da informação vai além da simples capacidade de um profissional organizar, compartilhar e utilizar dados. Atualmente é necessário que os profissionais dominem o manuseio da informação, mas também se adaptem constantemente aos novos suportes, fontes e às suas exigências. Com a crescente quantidade de informações disponíveis, que inclui tanto dados verídicos quanto desinformação, este profissional tem...

Vestibular schwannoma in patients with asymmetric sensorineural hearing loss: w...

Objectives: (1) To compare clinical and audiometric parameters between patients with vestibular schwannoma (VS) and patients with asymmetric sensorineural hearing loss (ASNHL) of unknown etiology; (2) to evaluate proposed protocols for VS screening. Study Design: Retrospective and cross-sectional. Materials and Methods: Demographic, clinical, and audiometric data were analyzed and compared in 208 patients with ...

No. of bitstreams: 0 Previous issue date: 2017-01-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); During the image acquisition process, some level of noise is usually added to the real data mainly due to physical limitations of the acquisition sensor, and also regardin...

Trauma Crânio-Encefálico Isolado como Causa de Coagulopatia Precoce: Caso Clínico

Resumo A coagulopatia associada ao trauma está descrita no trauma crânio-encefálico isolado. Apresentamos um caso onde a tromboelastometria (ROTEM ® ) foi o único sinal de alerta para coagulopatia precoce. Paciente do sexo feminino, 77 anos, vítima de queda de escadas. Assistida no local, foi intubada orotraquealmente e transportada ao Serviço de Urgência. Realizou tomografia computorizada de crânio que evidenc...
