Temporal bone 3D models – an innovative approach in otologic surgical training
Sousa Teles, Sofia; Claro, Ana; Ferraria, Lília; Neto, Mariana; Pires, Rafael; Oliveira, Leonor; Dias, Joana; Couto, Ana Miguel; Nelas, RicardoIntroduction: 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
Pires, Rafael; Pires, Rodrigo; Gasana, Sammy; Sousa Teles, Sofia; Couto, Ana Miguel; Oliveira, Leonor; Dentinho, Jorge; Antunes, LuísObjectives: 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...
Sousa Teles, Sofia; Ferraria, Lília; Areias, Catarina; Neto, Mariana; Pires, Rafael; Couto, Ana Miguel; Antunes, LuísIntroduction: 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
Oliveira, Leonor; Couto, Ana Miguel; Pires, Rafael; Oliveira, Jorge; André, Carla; Antunes, LuísAim: 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...
