Removal of cerumen (wax) from the ear forms a significant part of the workload of an otolaryngologist and is, therefore, an essential skill to master. [1] However, general practitioners, emergency department staff, nurses, audiologists, audiological physicians, and alternative medicine practitioners may all be confronted with the scenario of excess ear wax that causes difficulty in examination, hearing loss, or discomfort. [2]

In an evaluation of 279 children with acute otitis media with effusion, ear wax needed to be removed to visualize the tympanic membrane in 29% of consultations. [3] Although many options are available to attempt to clear ear wax, only methods that are used in routine otolaryngological practice (but are still applicable to practitioners of other disciplines) are discussed in this article, with a particular focus on microsuctioning. See the image below.

Relevant Anatomy

The ear is composed of external, middle (tympanic) (malleus, incus, and stapes), and inner (labyrinth) (semicircular canals, vestibule, cochlea) portions. The auricle and external acoustic meatus (or external auditory canal) compose the external ear. The external ear functions to collect and amplify sound, which then gets transmitted to the middle ear. The tympanic cavity (middle ear) extends from the tympanic membrane to the oval window and contains the bony conduction elements of the malleus, incus, and stapes. The primary functionality of the middle ear is that of bony conduction of sound via transference of sound waves in the air collected by the auricle to the fluid of the inner ear. The inner ear, also called the labyrinthine cavity, is essentially formed of the membranous labyrinth encased in the bony osseus labyrinth. The labyrinthine cavity functions to conduct sound to the central nervous system as well as to assist in balance.

Cerumen in the external ear canal is physiological. Indications to address the cerumen include the following [4] :

  • Difficulty in examining the full tympanic membrane
  • Wax occlusion of the external ear canal
  • As part of the workup for conductive hearing loss
  • Prior to taking the impression for hearing aid fitting
  • Suspected external ear canal or middle ear cholesteatoma
  • Suspected external ear canal pathology such as squamous cell carcinoma or eczema
  • As part of the follow-up to canal wall down mastoidectomy
  • As part of grommet insertion or middle ear surgery (preoperatively or perioperatively)
  • Patient request


Specific contraindications exist for each specific procedure. Individual assessment should dictate which technique is the most appropriate.

  • Contraindications to irrigation include the presence or history of a perforated tympanic membrane, 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.


See the list below:

  • Topical anesthetic drops have no documented benefits in ear wax removal.
  • Local anesthetic injections into the ear, although effective, are particularly painful and are, therefore, not used.


The techniques used in cerumen removal include microsuction, mechanical removal, and irrigation. Instruments are shown in the image below.

See the list below:

  • Operating microscope with focal distance of approximately 200 mm and magnification of 4-25 times
  • Suction device capable of 300 mm Hg suction pressure, with a reservoir and built-in filter
  • Suction tips, various sizes, including 16 and 18 gauge (ga)
  • Aural specula, various sizes
  • Crocodile forceps, various sizes
  • Wax hooks
  • Jobson Horne probes, various sizes

Mechanical removal

See the list below:

  • Headlight, otoscope, or microscope (for visualization)
  • Other equipment as listed above for microsuction


Patient positioning may vary according to individual clinician preference or may be dictated by anatomical limitations.

  • Usually, the patient is semi-reclined. Although having the patient sitting upright saves positioning time, the attic region is difficult to access with the patient in this position.
  • Positioning the patient supine with the head on a pillow simulates the operative view and allows good access to the external ear canal and tympanic membrane, including the attic. The supine position also aids patient stability. This is particularly beneficial if the patient experiences vertigo during the microsuction, as is often the case after mastoidectomy.

Patient positioning and room setup are shown in the images below.

Preparation and visual assessment

See the list below:

  • Assemble and prepare all necessary equipment.
  • Take time to explain the procedure to the patient and obtain consent.
  • Connect suction tip and turn on the suction machine and microscope light.
  • Position the patient’s head facing away from the operator, the neck flexed laterally and the shoulder pulled down.
  • Examine the pinna, outer portions of the external canal, and the adjacent scalp for any evidence of previous surgery incision scars, signs of infection, or discharge.
  • Inspect the outer ear canal opening, using the appropriate aural speculum, as shown below.
    View through an aural speculum. View through an aural speculum.
    See the list below:
    • The speculum should be the largest size that fits. It should be placed deep enough to clear the hair-bearing skin but not deeper, as unnecessary pain may result.
    • The speculum should be held with the first and second fingers. Use the other fingers to retract the pinna up and backward in an adult (retract the pinna up and downward in a child).
  • Assess the cerumen. Gently probe with a blunt instrument such as Jobson Horne curette to determine whether the cerumen is soft, hard, or bony hard.
  • Assess whether tympanic membrane is visible. Look for any air spaces around the cerumen.
  • Before beginning the cerumen removal, ensure that the microscope and operator are optimally positioned. The microscope should be positioned to provide the optimal view of the ear canal, and the operator should be sitting comfortably and with a straight back.


See the list below:

  • If space permits, use an instrument to remove the wax. A ring probe (Jobson Horne curette) may be used to scoop the wax out; experienced practitioners may prefer to use a wax hook. If the cerumen is of a harder consistency, attempt to push the wax away from the ear canal walls toward the middle and then pull it out with a crocodile forceps.
  • If the wax is occlusive, use the large-bore suction (16 or 18 ga) device to remove the wax piecemeal. As soon as the hair-bearing skin is passed, downsize the suction device to 20 ga or larger. As experience grows, one develops a sense of the depth of the tympanic membrane, which allows for safe use of the large-bore sucker closer to the tympanic membrane. But suctioning on the tympanic membrane with a large-bore risks causing a perforation and significant discomfort to the patient and should be avoided.
  • Once the cerumen is cleared, reposition the microscope. This may reveal additional cerumen or pathology, especially in the anterior recess or the attic area or if a mastoid cavity is present.
  • If the patient reports discomfort during the procedure, postpone the cerumen removal for 2 or more weeks and encourage the patient to instill ear drops such as sodium bicarbonate (5%) ear drops twice daily. Such drops soften the cerumen and make it easier to remove.

See the list below:

  • Try to stick to the anterior wall while clearing the canal. At the anterior wall, the angle with the tympanic membrane is more acute, and the transition to the tympanic membrane is less likely to be missed.
  • Ask the patient to report pain, as this is a safety net. Pain is likely due to trauma to the ear canal skin. However, touching the malleus can cause pain and is to be avoided. A very stoic patient may try to grin and bear the pain when the malleus is accidentally touched; if he or she does so, this warning sign may be missed.
  • Do not hesitate to postpone the cerumen removal for 2 weeks, as pain and time can be saved by softening the cerumen with drops first. Drops can be selected at the clinician’s individual preference, as reviews have failed to demonstrate significant differences between various drops. [5, 6, 7, 8] In 2009, a review of completed trials also failed to demonstrate a significant difference between using water or commercially available drops. [5]
  • Take special care with pediatric patients. Carefully explaining the procedure, allowing the child to touch the suction device, and introducing suction into the ear canal slowly may help children as young as 4 years to tolerate a microsuction session. However, most children only tolerate this procedure at age 8 years or older. Using a Jobson Horne probe or a ring curette may be a viable alternative in pediatric patients who do not tolerate microsuction.
  • 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 olive oil drops.
  • If visual inspection reveals a foreign body instead of or in addition to cerumen, removal of the foreign body may require different techniques. See Medscape Reference article Ear Foreign Body Removal Procedures for more information.
  • A 0-degree rigid endoscope may be quicker and easier to access than a microscope when visualizing the cerumen, ear canal, and tympanic membrane. [9]


See the list below:

  • Most patients tolerate the procedure very well with no analgesia. A minority of patients experience a mild amount of discomfort or even pain.
  • Some patients experience short-term vertigo.
  • Because of the noise generated by the suction tip, tinnitus may be worsened in some patients. Suction should be limited or avoided in patients with symptomatic tinnitus.
  • Hard cerumen, probes, specula, and suction devices may all cause lacerations to the ear canal skin. Minor bleeding and discomfort may result.
  • Using a large-bore suction device close to the tympanic membrane may cause trauma to the tympanic membrane, including a perforation. Such trauma usually heals spontaneously over the following weeks.
  • Inadvertent force to the ossicular chain may lead to conductive or sensorineural hearing loss.
