Abstract:Assessment of the local relationship between the adenoid and the Eustachian tube orifice may complement overall obstruction grading. However, some existing grading systems already include orifice involvement, so whether local assessment adds value beyond existing grading and clinical information remains to be established. This narrative review examines studies of orifice coverage, contact with or compression of the torus tubarius, and adjacent mucosal findings in relation to current middle ear status, functional mechanisms, disease-course prediction, and treatment benefit. Current evidence suggests that some local features are associated with the presence of otitis media with effusion (OME) and the degree of baseline hearing loss. Small studies suggest a possible association between local morphology and dynamic Eustachian tube function, and some anatomical grading systems have shown better discrimination of OME. Although follow-up outcomes differ among morphology groups, it remains unclear whether local morphology improves individual-level prediction of disease course or can guide treatment selection. In children who already have an indication for endoscopy, bilateral local findings may be documented and interpreted alongside disease duration, hearing, age, and adenoid-related symptoms. Future studies should standardize measurement definitions, pair local morphology with functional assessment on the same side, validate longitudinal prediction, and test treatment interactions to determine whether local information improves clinical decision-making.
