Spectroscopic Evaluation of Middle Ear Infection

This study is testing spectroscopy — a technique that analyzes how light interacts with tissue — to improve the diagnosis and evaluation of middle ear infections (otitis media). Middle ear infections are extremely common, especially in children, and accurately identifying the type and severity of infection (bacterial vs. viral, acute vs. chronic) can be difficult. Spectroscopy could provide a non-invasive way to quickly gather more information during evaluation. Participants are patients of any age (newborn to adult) who have been diagnosed with a middle ear infection and are already scheduled for a surgical procedure (such as placement of ventilation tubes or tympanoplasty). Spectroscopic measurements are taken during surgery alongside standard clinical assessments. You may be eligible if: - You (or your child) have been diagnosed with a middle ear infection - You are scheduled for a surgical procedure related to the infection - You (or your child's parents) can provide informed consent - You are not pregnant You may NOT be eligible if: - You are pregnant - You have cognitive impairment preventing consent - You are a parent with cognitive impairment who cannot consent on behalf of your child Talk to your doctor to see if this trial is right for you.
