Approximately 20% of the global population lives with some degree of hearing loss. Although it is often talked about in broad terms, hearing loss is a multifaceted condition affecting each person differently. Single-sided hearing loss is one less-discussed facet of the condition you may not have previously considered.
Single-sided hearing loss, also called unilateral hearing loss (UHL) or single-sided deafness if the loss is profound, occurs when a person loses hearing in only one ear. Although not as common as bilateral hearing loss (present in both ears), approximately one in 1,000 children is born with UHL. Additionally, an estimated 7% of adults in the United States live with the condition.
What Causes Single-Sided Hearing Loss?
Hearing loss is classified as sensorineural (inner ear), conductive (middle and outer ear) or mixed (inner, middle and outer ear). Common causes of single-sided sensorineural hearing loss include head trauma, acoustic neuroma (a benign tumor on the vestibular nerve), Ménière’s disease, infection and illness and loud noise exposure.
Conductive hearing loss occurs most frequently when the path of sound through the ear is damaged or obstructed. Common causes may include ear infection, perforated eardrum, impacted wax and foreign objects in the ear.
What Are the Signs of Single-Sided Hearing Loss?
Common signs of single-sided hearing loss may include tinnitus (ringing in the ear), frequently asking others to repeat themselves or feeling that they are mumbling, withdrawing from social situations, listening fatigue, trouble localizing sounds and turning the volume up on personal devices more than usual.
What Are Your Treatment Options?
In most cases, sensorineural hearing loss is permanent. When this is the case, hearing aids are the most common treatment option. These small but technologically advanced devices work by collecting and amplifying external sounds to improve communication and reduce the impact of hearing loss.
If your hearing loss is conductive, your provider will likely start by trying to fix the underlying cause. This may include administering antibiotics for ear infections or performing surgery or procedures to resolve damage or remove blockages. If conductive hearing loss is permanent, your provider will likely recommend hearing aids.
