Types of Ear Deformities

Ear deformities are more common than people think. Nowadays, children or even adults are suffering from this condition. However, some are dealing with microtia, while others are dealing with anotia. So, there is no single common ear deformity of the ear. There are many types of ear deformities; some are congenital, and some develop after birth due to injuries. Children or adults with these kinds of problems have to face many issues, such as fear of judgment, lack of acceptance, and rejection in relationships.

However, ear deformities are nothing to be afraid of, as with the growing technology, there are many treatments available for it. You just need to find the right treatment option and the best ENT specialist to cure it efficiently. In this blog, you will understand the types, causes, and treatment options for ear deformities.

What Are Ear Deformities?

Ear deformities are conditions where the outer ear is shaped, sized, and positioned differently than usual. These unusual formations of the ear may be present at birth (congenital) or may appear later due to accidents or injuries. There are many types of ear deformities; some can be treated without surgery, while others cause hearing loss and require surgical treatment.

Causes of Ear Deformities

Actually, there is no exact or scientifically researched cause of ear malformations, even though scientists are not able to understand the phenomenon as to why children are born with such a disease. However, these mentioned-below causes may be the possible reasons behind this:

Genetic Factors & Syndromes

Inherited gene mutations and syndromes, including Goldenhar syndrome, Down syndrome, and Treacher Collins syndrome, can cause structural ear deformities.

In-Utero Positioning

Sometimes, limited womb space can increase pressure and reduce sufficient blood supply to the ear. Moreover, when a child’s ear is pressed against the uterine wall or limbs for prolonged periods, causing malleable cartilage to fold and flatten.

Environmental Factors

Exposure to certain medications and drugs like isotretinoin (Accutane), thalidomide, valproic acid, and quinine can cause malformed ear disease, especially during pregnancy. Moreover, alcohol and nicotine consumption can also cause ear deformities.

Injuries

Physical damage, infections, and burns are also causes of ear deformities. It can be accidents, infections like auricular perichondritis, and fire burns, to the ear cartilage. This is uncertain and can be developed at any age.

Common Types of Ear Deformities and Their Treatment Options

Ear deformities are common, but they come in many forms. Depending on the condition and disease, appropriate treatment is required. Here are some common types:

1.Microtia

This is a congenital ear disease in which the outer ear is underdeveloped. It is classified into 4 stages. In the initial stage, it looks smaller than a normal ear, but it doesn’t affect hearing. While in the last stage (anotia), the ear is completely absent. The severity or size of microtia does not increase consistently with age.

Treatment of Microtia:

The main goal of treating microtia is to reconstruct the external structure and correct hearing loss. Treatment may involve surgery, while in some cases, it can be cured with implants. The main treatment options are:

• Autologous Rib Graft Reconstruction: A specialized surgeon uses patients’ own rib cartilage to construct a new ear, similar to the normal structure.
• Medora/Alloplastic Framework: A biocompatible or durable alloplastic material is used for ear reconstruction.
• Prosthetic Ear: In this treatment, a natural-looking artificial ear is created, using medical grade silicone to replace the missing and malformed area of the ear.

Treatment of Hearing Loss:

In some conditions of microtia, the ear canals are absent or narrow, due to which the problem of hearing loss will arise. The treatment options for hearing loss are given below:

• Bone-Anchored Hearing Aids (BAHA): It is a surgically implanted device that treats hearing loss. The device directly sends the sound into the inner ear via bone conduction, bypassing the middle and outer ear.
• Atresia Repair Surgery: It is a surgical process in which the damaged, narrowed, and abnormally formed ear canal is reshaped or widened to improve hearing.

2.Prominent/Protruding Ears (Otapostasis)

The ears protrude 2 centimeters from the head, making it look even more conspicuous and unusual. It is also a congenital ear deformity that occurs when the antihelix fails to develop properly, or if the ear canal is too deep or large. As these problems pushes the ear to stick out.

Treatment of Protruding Ears

The treatment option for a protruding ear varies from non-surgical to surgical procedures. These options are used to reshape or reposition the sticked out ear. The treatment options include:

• Otoplasty: It is a surgical procedure used to improve the shape and position of the ear. This procedure is usually performed on children above the age of 5 and adults.
• Non-Surgical Ear Molding: This technique is non-surgical, used to reshape a protruding ear. It is usually done at an early age of a child, as newly born babies have soft and pliable ear cartilage.
• Cosmetic Correctors: The skin-friendly material, such as silicone or Otostick, is designed to keep the protruding ear sticked with the skin of the head.

3.Constricted Ear

A congenital ear deformity, also researched as genetic, where the upper rim of the ear is folded, tight, or wrinkled. Sometimes, it looks like a pointer shaped ear. The real cause of it is unknown, but the belief is that there is a shortage of skin or cartilage.

Treatment Options Include:

There are both surgical and non-surgical options to treat constricted ear deformity.

• Ear Molding: A painless and non-surgical process used to correct the folded and constricted ear. This process should be done within an initial 2-3 weeks of birth.
• Otoplasty: This is a surgical option to reshape the existing molded ear cartilage into the normal ear shape.
• Cartilage Reconstruction: In this method, the rib cartilage of the patient is used to rebuild the upper ear structure.
• Skin Grafting: A surgical reconstructive technique used to expand the folded or wrinkled part of the upper ear. The procedure aims to increase the vertical height of the ear and straighten the rim to give a normal and realistic look.

4.Stahl’s Ear

Stahl’s ear is a rare congenital ear deformity resulting in the pointed ear shape. This is usually caused by an abnormal ‘third crus’ that creates a pointed appearance. This doesn’t affect hearing but may affect self-confidence, as the ear shape looks so weird and abnormal compared to normal looking ears.

Treatment Options for Stahl’s Ear

There are both surgical and non-surgical options to treat Stahl’s ear deformity:

• Ear Splinting: It is a non-surgical and highly effective process in which molding devices like EarBuddies are used to flatten the extra molded skin of the ear. It is best to do it in the first 2–8 weeks of a kid’s life.
• Cartilage Reshaping: A surgical process designed to correct the pointed-ear deformity.
• Cartilage Scoring: This is a surgical technique used to correct the “pointed” or “elf ear” shape of the ear. It is done through making precise, shallow cuts on the back of the stiff ear cartilage.

5.Cauliflower Ear

This is an ear deformity often seen in people like boxers, wrestlers, and rugby players. This is an acquired disease later in life, due to blunt trauma. In this condition, the ear looks swollen, discolored, and lumpy, and develops a cauliflower shape. When athletes like boxers receive multiple punches to the ear, there is repeated pressure and friction on the ear, leading to this condition.

Treatment Options for Cauliflower Ear Deformity:

The treatment of cauliflower ear deformity should be done earlier, within hours, as the stored fluid or blood in the ear may cause permanent cartilage hardening. The options of treatment are:

• Needle Aspiration: It is a medical procedure used to drain trapped blood from a swollen ear before it turns into a permanent deformity. The blood drains through the syringe or needle.
• Compression Dressings/Splints: These are tools used to press the skin firmly against the cartilage after blood withdrawal to prevent blood from refilling the area.
• Medications: If the injury is not major, then a few medications will be suggested to prevent infections.

Conclusion

Ear deformities are not just physical conditions but also an emotional challenge. These conditions can be treated effectively at a young age, and children do not face various social challenges, but in adulthood, abnormal ears make it difficult to cope with society and rejection. There are several types of ear deformities; some are congenital like microtia and protruding ears, while others are acquired later in life due to injuries and accidents.
