Key Takeaways:
- Microsuction uses a thin suction probe (1-3mm diameter) under direct microscope visualisation to remove wax without touching the eardrum
- The procedure typically takes 15-30 minutes for both ears and involves four stages: pre-examination, positioning, suction, and post-procedure check
- Fingertip airflow control allows clinicians to adjust suction pressure in real-time based on wax consistency
- Traditional suction units can reach 140 dB, while modern devices like Zephyr operate at 75 dB or below
How the Microsuction Procedure Works
Microsuction is a straightforward clinical procedure that typically takes 15–30 minutes. Here’s exactly what happens at each stage.
Step 1: Pre-Examination
Before any wax removal begins, your clinician will:
- Take a history — asking about previous ear problems, surgeries, or perforations
- Examine the ear — using an otoscope to assess the type and position of wax
- Determine the approach — deciding whether microsuction is appropriate
If your wax is very hard or impacted, you may be advised to use olive oil drops for a few days before returning for the procedure.
Step 2: Positioning
You’ll be seated in a clinical chair with your head tilted to expose the affected ear. The clinician will position their microscope or loupes for optimal visualisation.
Step 3: The Suction Process
The clinician uses a thin suction probe — typically 1–3mm in diameter — connected to a suction unit. The process involves:
- Gentle insertion of the suction probe into the ear canal
- Direct visualisation through the microscope throughout
- Controlled suction to draw wax away from the canal walls
- Fingertip pressure control to adjust suction strength in real-time
- Careful extraction of wax fragments, piece by piece
The suction probe never touches the eardrum. The clinician maintains a safe distance at all times, guided by magnified visualisation.
Step 4: Post-Procedure Check
After wax removal, the clinician will:
- Examine the ear canal and eardrum to ensure they’re healthy
- Note any findings such as inflammation or perforation
- Provide aftercare advice
The Equipment
A microsuction setup requires several key components:
The Suction Unit
The core device that generates controlled negative pressure. Traditional units can be noisy — some reaching 140 dB during operation. Newer devices have addressed this, with modern units like Zephyr operating at 75 dB or below. For help selecting the right unit, see our guide to choosing microsuction equipment.
The Suction Probe
A thin, sterile tube available in various diameters (typically 1–3mm). Clinicians select the appropriate size based on the ear canal and wax type.
Visualisation
Either a binocular microscope mounted on an adjustable arm, or head-worn loupes with LED illumination. This provides the magnification needed for safe, precise work.
The Speculum
A funnel-shaped device placed at the entrance to the ear canal to hold it open and provide a clear line of sight.
What Makes the Technique Effective?
Three elements combine to make microsuction effective:
- Continuous visualisation — The clinician never works “blind”
- Adjustable suction — Pressure can be modulated based on wax consistency
- Precision instruments — Small-diameter probes allow targeted wax removal
Clinician tip: Fingertip airflow control is critical for patient safety. The ability to instantly modulate suction pressure prevents trauma to the delicate ear canal lining. This is one of the key design features that separates advanced microsuction devices from basic units.
How Long Does It Take?
Most microsuction procedures take 15–30 minutes for both ears. Factors that affect duration include:
- Wax consistency — Soft wax is quicker to remove than hard, impacted wax
- Amount of wax — More wax naturally takes longer
- Canal anatomy — Narrow or curved canals require more careful work
- Patient cooperation — Staying still helps the clinician work efficiently
