Ear canal infections, or otitis externa is a frequent patient complaint in ENT clinics near you. In this blog, we will review the ear anatomy, what causes otitis externa, the diagnosis and management, as well as prevention
The Ear Canal: A Natural Cleaning Mechanism
Our auditory system is a complex system, and the ear canal plays a pivotal role. It’s a passage that leads from the outer ear to the eardrum, not only capturing sound waves but also equipped with a self-cleaning mechanism. The ear canal’s structure helps to naturally expel debris, ensuring our ears remain clean and functional.
What is Otitis Externa?
Otitis externa, commonly known as swimmer’s ear, is an infection of the outer ear canal. It is typically caused by bacteria or fungi, often triggered by moisture remaining in the ear after swimming or showering. Symptoms include ear pain, itching, redness, and potential discharge from the ear. Sometimes, the pain extended to the TMJ or the joint connecting the jaw to the skull, causing difficulty in chewing.
Ear Canal Infections: Risk Factors and Causes
Understanding what sets the stage for infection of the ear canal is crucial. Prolonged moisture exposure, humid climates, using earphones for extended periods, and even aggressive ear cleaning practices can heighten the risk. Avoidance of these factors can prevent you from developing otitis externa.
Why Should You Consult an Ear Doctor Near You?
The ear is a delicate organ for hearing and balance. Any infection in this area, if untreated may lead to unwanted consequences (see below). It is important to consult an ENT doctor near you for proper diagnosis and a tailored treatment plan. Most of the time, history and ear examination are enough to diagnose an ear infection. However, if you have comorbid illnesses, your ENT doctor in Palawan may request for additional diagnostic tests to help in the diagnosis and treatment.
Treatment of Otitis Externa
Your trusted ENT doctor specialist will give you a personalized treatment plan for your otitis externa. This may involve antibiotic or antifungal ear drops, pain management, and recommendations on how to keep your ear dry during recovery. Sometimes, when the ear canal is too swollen, your ENT doctor near you may place a small piece of medicated gauze inside your ear canal.
Complications of Untreated Otitis Externa
Unchecked otitis externa can spread beyond the ear and lead to serious complications, particularly for individuals with comorbid illnesses. Inside the ear, it can lead to abscess or pus formation, and even a complication known as an ear polyp, as well as hearing loss. If it spreads to the nearby areas, it may cause cellulitis of the skin, or perichondritis of the cartilage around the ear canal. In patients with diabetes or weak immune systems, life threatening conditions such as spread to the bones and tissues of the skull base (malignant otitis externa) and sepsis (infection spreading through the bloodstream) may occur.
Preventing Otitis Externa
Prevention is indeed better than cure. To avoid otitis externa, keep your ears dry after swimming or showering, avoid inserting objects into your ears, and opt for earplugs during swimming sessions. Some divers customarily apply a mixture of vinegar and rubbing alcohol after sea exposure, as this can help dry out moisture and potentially reduce the risk of otitis externa.However, ensure your eardrum is intact and consider consulting a medical professional, like an ENT doctor, before using such solutions.Regular ear hygiene, coupled with professional guidance, can keep ear infections at bay.
Remember that your ears deserve attentive care. If you have ear infections, consult an ENT near you to arrive at a prompt diagnosis and proper treatment. With knowledge, prevention, and professional care, you are ensured that you have healthy ears.
