Jobson Horne Probe

What it is

The Jobson Horne probe is a double-ended stainless steel instrument: one end carries a small ring loop designed to engage and extract softened wax, and the other is a fine blunt probe tip used for palpation and foreign body localisation. Its slender profile allows atraumatic access to the external auditory canal without requiring irrigation.

When & how it's used

It is used during ear toilet procedures to remove impacted or softened cerumen under direct vision, either with a head mirror and light or with a video otoscope. The probe tip is also used to palpate the canal wall and tympanic membrane margin, and to assess the position of foreign bodies prior to extraction.

The Jobson Horne probe is one of the oldest and most widely used instruments in ENT practice. Its double-ended design means a single instrument serves two complementary functions: the ring loop on one end hooks beneath a bolus of wax or a foreign body to draw it laterally out of the canal, while the blunt probe tip on the other end allows the clinician to gently palpate, separate, and assess structures without cutting or abrading the delicate canal skin. It is lightweight, easy to sterilise, and requires no ancillary equipment, making it indispensable in both primary care and specialist ENT settings.

When used alongside a good light source and magnification — or a video otoscope — the Jobson Horne probe allows precise, controlled wax removal under direct vision. This makes it safer than blind syringing in patients with a history of perforation or canal pathology, and it is the preferred first-line tool in many ENT departments for ear toilet. For harder or more impacted wax, it is commonly used in combination with a cerumenolytic agent applied a few days prior to the appointment.

Design features

• Ring loop end: Small circular loop at the tip engages and extracts soft or semi-solid cerumen without compacting it deeper into the canal.
• Fine probe tip: Blunt, smooth probe end for safe palpation, separation of debris, and assessment of foreign body position.
• Slender shaft: Narrow profile fits within the external auditory canal alongside an aural speculum.
• Stainless steel construction: Fully autoclavable; resistant to deformation and corrosion with repeated sterilisation cycles.
• Balanced handle: Knurled or smooth central handle provides grip without bulk.

Frequently Asked Questions

Can the Jobson Horne probe be used on a perforated tympanic membrane? Yes — unlike syringing, the probe does not introduce fluid under pressure, so it is generally safe to use in patients with a known or suspected perforation. Care must still be taken not to contact the membrane directly with the loop or probe tip.

What is the difference between the ring loop end and the probe end? The ring loop is used to engage and extract wax or debris by hooking beneath it and drawing it out laterally. The probe tip is used for palpation, probing around foreign bodies, and assessing canal anatomy rather than for extraction.

Does wax need to be softened before using this instrument? For hard, impacted cerumen, pre-treatment with a cerumenolytic drop (olive oil, sodium bicarbonate, or commercial preparations) for several days prior improves ease of removal and reduces trauma to the canal. Soft or recently accumulated wax can often be removed directly without pre-softening.

How is the Jobson Horne probe sterilised? It is fully autoclavable by standard steam sterilisation. The instrument should be cleaned of all debris before autoclaving. It can also be cold sterilised with appropriate disinfectant solutions between cases in a clinic setting.
