If you're a left-brain thinker, chances are you use your right hand to hold your cell phone up to your right ear, according to a newly published study from Henry Ford Hospital in Detroit.

The study ­– to appear online in Journal of the American Medical Association (JAMA) Otolaryngology-Head & Neck Surgery ­– shows a strong correlation between brain dominance and the ear used to listen to a cell phone. More than 70 percent of participants held their cell phone up to the ear on the same side as their dominant hand, the study finds.

Left-brain dominant people – who account for about 95 percent of the population and have their speech and language center located on the left side of the brain – are more likely to use their right hand for writing and other everyday tasks.

Likewise, the Henry Ford study reveals most left-brain dominant people also use the phone in their right ear, despite there being no perceived difference in their hearing in the left or right ear. And, right-brain dominant people are more likely to use their left hand to hold the phone in their left ear.

"Our findings have several implications, especially for mapping the language center of the brain," says Michael Seidman, M.D., FACS, director of the division of otologic and neurotologic surgery in the Department of Otolaryngology-Head and Neck Surgery at Henry Ford.

He notes that the study also may offer additional evidence that cell phone use and tumors of the brain, head and neck may not necessarily be linked.

Since nearly 80 percent of people use the cell phone in their right ear, he says if there were a strong connection there would be far more people diagnosed with cancer on the right side of their brain, head and neck, the dominant side for cell phone use.
