The collapse usually involves the outer portion of the canal, right at the anterior edge of the conchal cartilage. It is is a major cause of cerumen impaction and makes it extremely difficult to remove the cerumen from the wider medial portion of the canal. At times, the use of a nasal speculum facilitates the visualization of the eardrum and the introduction of a cerumen curette or the nozzle of an ear syringe. Finally, it is sometimes impossible to introduce a hearing aid into a collapsed ear canal.
