Claim 1: Interconnections in the head allows the candles to drain the entire system through the ear.
FALSE: Liquids and gases cannot pass through a normal healthy ear drum. For example, most people have experienced pressure in their ears when changing altitude while driving in mountains, or ascending or descending during flight. This pressure sensation results from atmospheric pressure changes acting on the middle ear space. If liquids and gases could readily pass through the ear drum, changes in atmospheric pressure would not create a "change in pressure" sensation. And, by the way, there are no empty interconnecting passages. Yes, there are arteries, veins, lymph systems, and neural networks, but they have very specific ongoing functions that cannot be impinged upon while mysterious things are allegedly drained through solid barriers!
Claim 2: Oxygen drawn through the candle will create a vacuum.
FALSE: A basic scientific evaluation measured the amount of vacuum force created by ear candles when placed in a simulated human ear canal. Despite numerous trials, this presumed phenomena (creation of a vacuum) simply did not occur at any point during the trials (Seely, Quigley, Langman, 1996; Kaushall and Kaushall, 2000).
Claim 3. When a vacuum is created, it will pull residue out from the ear canal.
FALSE: A scientific study compared individuals' ear canals before and after candling. Some subjects had impacted earwax and others had completely clear ear canals prior to candling. In all instances, after candling, there was no reduction in the amount of ear wax found in individual's ear canals. In fact, after candling, some participants had candle wax deposited in their ear canals. Indeed, meticulous analysis of the contents in the ear candle after use (using gas chromatography) showed multiple alkanes of candle wax, with no constituents of cerumen (Seely, Quigley, Langman, 1996). If anything, individuals subjected to ear candling have complained about significant pain from the heat funneled into the ear and very loud "bubbling" noises created from the candle.
Claim 4. The method is safe, noninvasive, and effective.
FALSE: Candling is dangerous. Survey responses from medical specialists (otolaryngologists) in the United Kingdom reported ear injuries from ear candling including; burns, ear canal occlusions and ear drum perforations and secondary ear canal infections with temporary hearing loss (Seely, Quigley, Langman, 1996). In some patients, multiple complications were found. There have been reports within the United States demonstrating ash remnants and residue from ear candling coating the eardrum (Kutz and Fayad, 2008). Additionally, significant fires associated with ear candling have been reported, one of which led to the user's death (Powell, 2005). In recent years Health Canada's Medical Device Regulatory Agency declared that selling ear candles requires a license from Health Canada before anyone can sell them for therapeutic purposes. Yet, Health Canada has not issued any licenses for ear candles, consequently selling ear candles for "therapeutic purposes" in Canada is illegal. The U.S. FDA and Health Canada have acted against manufacturers of ear candles by providing alerts to consumers not to use ear candles, seizing products, and issuing bans for importing ear candles. Despite the proactive stance of these government agencies, there are hundreds (perhaps thousands) of "practitioners" around the United States ready to perform the procedure (see multiple FDA references, below).
Ear candling is dangerous (even when used as directed by the manufacturer) and serves no legitimate purpose and there is no scientific evidence showing effectiveness for use. It is of significant concern that some ear candles are advertised for use with children (including babies), potentially placing them at great risk—with no known or documented benefit.
As hearing professionals and doctors, we strongly recommend prior to undertaking ear candling, consumers and patients are urged to discuss the matter with their physician, audiologist, or hearing aid dispenser. Bottom line: Ear candling is ineffective and potentially dangerous and we do not recommend it at any time for any reason.
