Complications of bone-anchored hearing devices
Advances in Oto-Rhino-Laryngology
|March 11, 2011
Summary
Complications with bone-anchored hearing devices involve soft tissue and bone issues, with skin irritation being most common. Proper patient selection and care are key to minimizing these risks.
Area of Science:
- Otorhinolaryngology
- Biomedical Engineering
- Implantology
Background:
- Bone-anchored hearing devices (BAHDs) are used to treat hearing loss.
- Complications associated with BAHDs can affect both soft tissue and bone.
- Understanding these complications is crucial for patient management.
Purpose of the Study:
- To review the types and incidence of complications associated with bone-anchored hearing devices.
- To identify risk factors and management strategies for these complications.
- To emphasize preventative measures for minimizing adverse outcomes.
Main Methods:
- Review of literature on complications of bone-anchored hearing devices.
- Classification of complications into soft tissue and bone-related categories.
- Analysis of factors contributing to complications, including patient demographics and surgical technique.
Main Results:
- Soft tissue complications, such as skin irritation, are more frequent than bone complications.
- Bone complications include early (osseointegration failure) and late (infection, trauma) issues.
- Pediatric patients exhibit a higher predisposition to both soft tissue and bone complications.
Conclusions:
- Most complications can be managed conservatively with topical therapy and wound care.
- Revision surgery may be necessary for severe cases like extensive skin overgrowth.
- Optimal patient selection, surgical precision, and implant hygiene are paramount for complication prevention.

01:11The Auditory Ossicles
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

01:16Anatomy of the Ear
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
01:13The Cochlea
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
