Most AMEs look cursorily in the canal to ensure it isnt full of wax. If this is what you are relying on ask for an ENT opinion. Looking in the ear for a second is not an ENT examination. you may have obstruction to sound for other reasons, or other pathology that can be managed or resolved.
It would be sad to have your career ambitions dashed from ignorance. Deafness happens for a reason!
Good luck
