Researchers are evaluating a new Short Wave Infrared SWIR otoscope as a diagnostic tool for detecting middle ear infections in children aged 1 to 17 years who are undergoing tympanostomy tube placement surgery. The study aims to provide preliminary data to support future research by comparing the SWIR otoscope with the standard white light otoscope. Otitis media is a common cause for ear infections and tympanostomy tube surgeries, but current diagnosis methods are often subjective and may lead to misdiagnosis or overtreatment. In this study, all participants will have their middle ears imaged using both the SWIR otoscope and the white light otoscope simultaneously during their surgery. The SWIR otoscope records images in AVI format capturing both SWIR and white light data. The presence or absence of middle ear fluid will be confirmed during the standard surgical procedure by fluid removal. The images are then analyzed by a physician and a computer program to assess fluid presence. This comparison will help evaluate the accuracy of the SWIR otoscope. Participants will undergo imaging during their scheduled surgery, with no additional intervention beyond standard care. The study measures the number of accurate diagnoses made by the SWIR otoscope within 30 minutes, confirmed by surgical findings. The involvement includes image analysis and recording during surgery with no extra follow-up beyond the procedure. The total participation period corresponds with the surgical event and imaging process, aiming to improve diagnostic tools for middle ear infections in children.

This table compares participation in this trial with other options available for this condition. The information is drawn from published research and the trial’s study details and is provided for educational purposes only.
| Factors | SWIR Otoscope (Short Wave Infrared Otoscopy) | Standard White Light Otoscopy |
|---|---|---|
| What it is | A handheld imaging device that uses short wave infrared light to visualize the middle ear and assess for presence of fluid through enhanced otoscopic imaging. | A conventional otoscope that uses visible light to examine the tympanic membrane and look for signs of middle ear fluid. |
| Role in trial | Investigational imaging device evaluated for its accuracy in detecting middle ear effusion in children during routine surgical care. | Standard diagnostic method used alongside SWIR otoscopy for comparison in all enrolled children. |
| Primary use | To improve detection of middle ear effusions in pediatric patients by allowing enhanced visualization compared to standard otoscopy. | To visually examine the eardrum for signs of middle ear effusion or infection in children. |
| How it is performed | Images of the middle ear are captured using the SWIR otoscope before tympanostomy surgery; both SWIR and white light modalities are recorded at the same clinical assessment. | Routine otoscopic exam with visible light is conducted to inspect the tympanic membrane prior to surgery. |
| Evidence status | Early clinical studies suggest SWIR otoscopy may improve diagnostic accuracy for middle ear effusions compared to standard otoscopy, but further multicenter validation is ongoing. Results from this specific trial are not yet established. | Standard otoscopy is foundational in pediatric care, but published evidence notes limitations in accuracy for detecting effusions, particularly in distinguishing fluid from other causes of inflammation. |
| Important limitations | Clinical evidence for SWIR otoscopy remains limited to early pilot studies and single-center trials; diagnostic accuracy, usability, and cost-effectiveness in routine pediatric practice are not yet fully established. | Conventional otoscopy frequently misidentifies effusion status, particularly when training or visualization conditions are suboptimal; accuracy depends strongly on clinician experience. |
