Ear candling is a form of alternate therapy that has been widely discouraged by health organizations like the FDA. The efficacy of ear candling is not backed by science and the procedure puts the patient at risk of injuries to the ear and face. 
Ear Candling is an alternate medical therapy intended to remove wax from a patient’s ears. Manufacturers claim that ear candling helps treat discomfort in the ears and sinuses, rhinitis, sinusitis, “glue” ear, colds, flus, migraines, and hearing loss. The candle usually consists of a tube of linen coated in beeswax with additives like honey or essential oils.
The procedure includes placing a hollow candle in the ear canal and lighting the other end of the candle, usually while the patient is lying on their side. This allegedly causes negative pressure to build up in the ear canal to help suction the wax out of the ear. Other suppliers claim that the heat from the candle melts earwax so that the wax can leave the patient’s ear in the following days. 
The FDA does not approve the use of ear candles to treat any condition and warns that ear candling can result in serious injuries, even when used according to the manufacturers’ instructions.
The Mayo Clinic also discourages the use of ear candling and claims that it isn’t an effective or safe treatment for any condition. The process can have the opposite effect of removing ear wax and can actually push earwax deeper into the ear canal, causing it to feel clogged along with other hearing problems. 
A patient followed up with her doctor after a session of ear candling and found a large piece of candle wax lodged in her ear canal that had been causing hearing problems. The patient told her doctor that the candling practitioner had burned their hand on the candle and dripped candle wax into the patient’s ear during the session. The patient had the candle wax removed from her ear while under anesthesia, but she still suffered from mild hearing loss in her right ear that hadn’t improved by her follow-up appointment one month later. 
A study was conducted to test the ear candling manufacturers’ claims that ear candling helped remove ear wax by creating negative pressure in the ear canal. The study was conducted on an artificial ear by measuring pressure levels in the ear canal throughout a candling session. The study concluded that the practice did not create any negative pressure in the ear or remove any ear wax. 
In one study about ear candling, 122 doctors from the Northwest Academy of Otolaryngology-Head and Neck Surgery were surveyed about their patients and ear candling. 40 doctors reported having patients that admitted to using ear candling, and 20 doctors reported having treated patients with injuries that resulted from ear candling.
