Removal of cerumen or wax from the ear forms a significant part of the workload of an otolaryngologist and is, therefore, an essential skill for physician assistants (PA) to master.
There are multiple methods and techniques for removal of cerumen. Some are based on –patient request, –consistency of cerumen or –supervising physician’s preference.
Cerumen Removal of cerumen impaction options include; – Observation – cerumenolytic agents – Irrigation – Manual removal other than irrigation may be performed with a curette, probe, hook, forceps, or suction under direct visualization with headlight, otoscopy, or microscopy. – Combinations of treatment options such as cerumenolytic followed by irrigation; irrigation followed by manual removal, etc. The training, skill, and experience of the clinician plays a significant role in the treatment option selected. Patient presentation, preference, and urgency of the clinical situation also influence choice of treatment

• Warm irrigation under direct visualization (cold water stimulates calorics may cause vertigo). • Must ensure TM is in intact! • Review of completed trials did NOT demonstrate a significant difference between using water or commercially available drops

[Best Evidence] Burton MJ, Doree C. Ear drops for the removal of ear wax. Cochrane Database Syst Rev. Jan 21 2009;CD004326. Contraindications
Contraindications to irrigation include the presence or history of a tympanic membrane perforation, previous pain on irrigation, or previous surgery to the middle ear. A relative contraindication to probing is the inability to visualize the ear canal. Relative contraindications to microsuction are severe previous exacerbation of tinnitus, very hard cerumen, and an uncooperative patient. Exceptional caution has to be used when clearing cerumen in patients who have undergone a mastoidectomy in the past, during which sensitive anatomical structures like the facial nerve and semicircular canals may have been exposed.
Pearl Adjust to the individual patient’s needs.
Meticulous cleaning is required in patients with otitis externa, but less so if they are having a mold made for a hearing aid.
However, for patients who simply present with excessive wax buildup, the clinician only needs to remove most of the cerumen, and the rest can be cleared with weekly drops.
