is the main hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss and thus providing a basis for diagnosis and management.
Hearing aids are small electronic devices that can be highly customized to address different types of hearing loss. All digital hearing aids contain at least one microphone to pick up sound, a computer chip that amplifies and processes sound, a speaker that sends the signal to your ear and a battery for power.
Premium hearing devices provide additional features, such as custom sound settings and self-adjustable settings. OTC hearing aids, meanwhile, are not as customizable, and for this reason, not everyone is a good candidate for OTC.
Hearing aids are typically recommended if your hearing test results show hearing loss on an audiogram.
Anyone who suspects they have hearing loss should receive testing and treatment. Hearing loss is not just bad for communication, it's also bad for your health. People with untreated hearing loss have higher levels of brain atrophy and auditory deprivation.
Hearing aids are custom-programmed to address your unique pattern of hearing loss. They are most often prescribed for people who have a type of hearing loss known as "sensorineural," meaning that some of the tiny hair cells of the inner ear are damaged. The surviving healthy hair cells pick up the sound delivered by the hearing aid and send them as neural signals to the brain via the auditory nerve. For people with mild-to-moderate hearing loss, standard hearing aids work best. "Power" models are often used for people who have severe-to-profound hearing loss as the technology can provide more power to treat a severe hearing loss.
Hearing aids can be classified into two main groups: in-the-ear (ITE) styles and behind-the-ear (BTE) styles.
Our guide to hearing aid types and styles discusses many options available to you. Sizes range from virtually invisible to filling the entire bowl of the ear. Your hearing care professional will be a vital asset in helping you pick the best style for you. You might also find it helpful to review the basic parts of a hearing aid.
Many of the hearing aids produced today use telecoils and even advanced technology like artificial intelligence. Telecoils improve hearing in public settings, such as theaters and airports. Meanwhile, wireless technology allows two hearing aids (one on each ear) to communicate with each other and essentially operate together as one complete hearing system. It also means hearing aids can connect to external sources of sound that are transmitted wirelessly, such as via Bluetooth.
Even better? Many manufacturers now make accompanying hearing aid apps that give users added control over their devices.
Once a hearing healthcare professional recommends hearing aids for you, a number of factors will be considered when selecting and fitting a device. The best fit for you will depend not only on the severity and type of hearing loss you have but also your budget, cosmetic preferences, career demands and other concerns. Your provider will likely perform real ear measurement to verify the amplification levels.
Because hearing aids are personalized, not every brand, style or technology level of hearing aid is suited for everyone. Even two people with the same hearing loss may end up with different hearing aids based on other selection criteria. This can make comparing hearing aids difficult. It’s best to talk to your hearing healthcare provider about what options and features are ideal for you.
Signia is one of the largest hearing aid brands in the world. Signia hearing aids are manufactured by WS Audiology, the same parent company that manufactures Widex and Miracle Ear hearing aids. Prior to being purchased by Sivantos in 2015, and merged into WS Audiology in 2019, Signia hearing aids were manufactured under the Siemens brand name.
Endoscopy is a diagnostic medical procedure that’s minimally invasive.
Nasal endoscopy, also referred to as Rhinoscopy, is typically performed in an otolaryngologist's or ear, nose, and throat office where they have a direct, high-quality and magnified vision as they evaluate your sinus and nasal passages.
A nasal endoscope is an instrument that consists of a rigid, thin tube with fiber-optic cables. It connects to a video camera and light source where magnified images project onto a screen. The otolaryngologist then captures and records the endoscopic images to document for each patient. During a nasal endoscopy procedure, the ear, nose and throat physician inserts the instrument into your nose and guides it through your sinus and nasal passages as they view the images of the area they're examining. The procedure helps with diagnosing and treating different health conditions. Sometimes, the physician may use small tools to perform certain tasks like gathering tiny tissue samples.
Nasal endoscopy indications may include:
Findings of a study show office-based biopsy and nasal endoscopy are an important and safe diagnostic tool to evaluate sinonasal neoplasms. This procedure is normally safe and gives physicians the diagnostic information they require to make changes to treatment decisions, if needed. Procedure limitations do exist, generally accuracy-related.
Throat endoscopy, also known as laryngoscopy or pharyngoscopy, is a medical procedure used to examine the throat, larynx (voice box), and surrounding structures. It involves the use of a flexible or rigid endoscope, which is a thin, tube-like instrument with a light and a camera on the end.
Laryngoscopy may be indicated for the evaluation of patients with the following:
In particular, patients at high risk of head and neck cancer (eg, heavy smokers or alcohol users) may benefit from laryngoscopy, especially if they have had hoarseness, sore throat, or ear pain for 2 weeks. Laryngoscopy can also be useful to evaluate the airway prior to orotracheal intubation. Urgent laryngoscopy may be indicated in patients with angioedema, stridor, epistaxis, and/or craniofacial trauma. Flexible laryngoscopy can be tried for patients who do not tolerate direct laryngoscopy.
In patients with stridor or angioedema, stimulation of the laryngopharynx may further compromise the airway. If laryngoscopy is essential, it should be done in the controlled setting of an operating room with a person skilled at difficult airway management (including surgical techniques) present.
