What technique is used in ear irrigation to facilitate the exit of wax?

The technique of pulling the ear upward and backward is the correct method used in ear irrigation to facilitate the exit of wax. This specific maneuver helps to align the ear canal in a way that maximizes the opening, allowing for easier passage of the irrigation fluid and any cerumen (earwax) out of the ear. By performing this action, it straightens the ear canal, which can be particularly beneficial in ensuring that the fluid can flow effectively and help dislodge any impaction.

This positioning is especially important for adults, as the ear canal in adults has a different orientation compared to that in children. Thus, this technique is not just a random choice but is based on anatomical considerations, ensuring that the procedure is both effective and safe. Other techniques mentioned, like pulling the ear forward or pressing on the eardrum, do not facilitate the optimal alignment needed for effective wax removal during irrigation.
