Ear Problems in Diving and How to Avoid Them

Ear Problems in Diving and How to Avoid Them

For most divers, the sensation of gliding weightlessly through the underwater world is one of pure joy. Yet, even the most seasoned among us can encounter an unwelcome guest: ear problems. These issues, ranging from mild discomfort to severe pain, can quickly put a damper on your dive plans and, in some cases, lead to more serious complications. Understanding why they occur and how to prevent them is crucial for a safe and enjoyable diving career.

Barotrauma: The Pressure Culprit

The most common ear problem divers face is barotrauma, which literally means "pressure injury." As you descend, the ambient pressure increases, and this pressure is transmitted to the air spaces in your body, including your middle ear. If the pressure in your middle ear isn't equalised with the external water pressure, the eardrum can be pushed inwards, causing pain and potentially leading to injury.

Symptoms of ear barotrauma can range from a feeling of fullness or mild discomfort to sharp pain. In more severe cases, you might experience ringing in your ears (tinnitus), dizziness, or even a ruptured eardrum, which can lead to hearing loss and allow cold water to enter the middle ear, causing vertigo. Ascending with unequalised ears can also cause barotrauma, though this is less common.

Prevention is key for barotrauma:

• Equalise early and often: Don't wait until you feel pain. Start equalising gently before you even leave the surface and continue frequently throughout your descent, especially in the first 10 metres.
• Use a technique that works for you: The Valsalva manoeuvre (pinching your nose and gently blowing) is common, but try other methods like the Frenzel manoeuvre (using your tongue to push air into your Eustachian tubes) or swallowing. Many divers find a combination works best.
• Descend feet first: This orientation can make equalisation easier as it helps keep your Eustachian tubes open.
• Avoid diving with a cold or congestion: If your Eustachian tubes are blocked by mucus, equalisation will be difficult, if not impossible.
• Take it slow: If you're having trouble equalising, slow your descent, ascend slightly, try again, and if necessary, abort the dive. There's no shame in calling a dive for safety.

Reverse Block: A Less Common but Troublesome Issue

While barotrauma on descent is more prevalent, a "reverse block" can occur during ascent. This happens when air gets trapped in your middle ear during descent, and as you ascend and the ambient pressure decreases, this trapped air expands. If it cannot escape through the Eustachian tubes, it puts outward pressure on the eardrum, leading to pain and potentially a rupture.

Reverse blocks are often associated with diving with congestion or taking decongestants that wear off during the dive. The decongestant might allow you to equalise on the way down, but as its effects fade, the Eustachian tubes can become blocked again, trapping air.

To prevent reverse block:

• Never dive with congestion or a cold.
• Be cautious with decongestants: If you must use them, consult a dive physician and ensure their effects will last for the entire dive and ascent.
• Ascend slowly: A slow, controlled ascent allows more time for any trapped air to escape.
• If you feel pain during ascent: Descend a meter or two, try to equalise (swallowing or wiggling your jaw can help), and then slowly resume your ascent. If the pain persists, you may need to make a very slow, controlled ascent, potentially with some discomfort.

Ear Infections: When Microbes Join the Party

Beyond pressure-related issues, ear infections are another common problem for divers, particularly "swimmer's ear" (otitis externa). This is an infection of the outer ear canal, often caused by bacteria or fungi thriving in warm, moist environments. Repeated exposure to water, especially in tropical climates, can wash away the protective earwax and leave the ear canal vulnerable.

Symptoms include itching, redness, swelling, and pain in the outer ear, which can worsen when the ear is pulled or touched. In some cases, there might be discharge.

Preventing ear infections:

• Rinse your ears: After diving, rinse your ears with fresh water.
• Dry your ears thoroughly: Use a towel or a hairdryer on a low, cool setting from a distance.
• Consider ear drops: Over-the-counter drying ear drops (e.g., those containing alcohol or acetic acid) can help dry out the ear canal and restore its acidic balance. You can also make a simple solution of equal parts white vinegar and rubbing alcohol.
• Avoid cotton buds: These can push earwax deeper into the ear canal or scratch the delicate skin, increasing the risk of infection.
• Maintain good hygiene: Clean your diving mask straps and hoods regularly.

When to Seek Help

If you experience persistent ear pain, hearing changes, discharge, dizziness, or any other concerning symptoms after diving, it's important to seek medical attention. A doctor, particularly one with diving medicine experience, can diagnose the problem and recommend appropriate treatment.

In many cases, a ruptured eardrum will heal on its own, but it requires time out of the water. Infections may need antibiotics or antifungal drops. Prompt treatment can prevent more serious complications and get you back in the water safely.

Understanding the causes of ear problems and adopting preventive measures is fundamental for every diver. By taking care of your ears, you can continue to enjoy the incredible experiences the underwater world has to offer without unnecessary discomfort or risk.
