To aid readability of the numerical data in our reviews, we round many percentages to the nearest whole number. In addition, we use a regular surveillance protocol to capture harms alerts from organisations such as the FDA and the MHRA, which are added to the reviews as required. We included RCTs and systematic reviews of RCTs where harms of an included intervention were assessed, applying the same study design criteria for inclusion as we did for benefits. We excluded all studies described as 'open', 'open label', or not blinded unless blinding was impossible. There was no minimum length of follow-up. Study design criteria for inclusion in this review were: published systematic reviews and RCTs in the English language, at least single-blinded, and containing more than 20 individuals (10 in each arm) of whom more than 80% were followed up. All data relevant to the review were then extracted by an evidence analyst. Studies selected for inclusion were discussed with an expert contributor.

Full texts for potentially relevant studies were then assessed against predefined criteria by an evidence analyst. Titles and abstracts identified by the initial search, run by an information specialist, were first assessed against predefined criteria by an evidence scanner. We also searched for retractions of studies included in the review. Additional searches were carried out in the Database of Abstracts of Reviews of Effects (DARE) and the Health Technology Assessment (HTA) database. The following databases were used to identify studies for this systematic review: Medline 1966 to July 2014, Embase 1980 to July 2014, and The Cochrane Database of Systematic Reviews 2014, issue 6 (1966 to date of issue).

If wax needs to be removed, then various options are available: irrigation (syringing with unregulated manual syringes should no longer be used), wax softeners/solvents, irrigation following wax softeners, mechanical removal, or microsuction.īMJ Clinical Evidence search and appraisal July 2014. Since the deep ear canal may be wider than the opening, a large plug of dry, hard wax deep in the canal can be particularly difficult to remove.

Impacted wax can become adherent to the ear canal skin and tympanic membrane and make removal more difficult. Wax may obscure the view of the tympanic membrane and may need to be removed for diagnostic reasons. The wet, dead keratin can become infected and an otitis externa develop. When wax gets wet, the keratin swells and can lead to the sudden onset of complete occlusion of the canal and a hearing loss. Accumulation can reduce the efficiency of hearing aids. However, partial blockage of the canal alters the resonant properties and the quality of the hearing.

To cause a significant conductive hearing loss, the wax must completely occlude the ear canal. Overall wax is sticky, waterproof, and protective, and there should be a thin coating of wax near the external opening of the canal. Wax is a mixture of all three components, with keratin being predominant. In the outer part of the canal are modified sweat glands (ceruminous glands), which secrete a modified sweat that has bacteriocidal and fungicidal properties, and sebaceous glands that produce an oily material and usually discharge in the hair follicles at the outside of the canal. To prevent the deep ear canal becoming filled with dead skin cells, this skin is migratory and moves from the deep canal outwards. There is no soft tissue between the ear canal skin and the bone, and this gives the ear canal resonance properties that enhance the usual range of sounds we hear at the tympanic membrane. The outer third has cartilaginous and soft tissue walls, while the deep two-thirds has continuous bony walls. The external ear canal in adults is about 24 mm long.
