A 7-year-old Seattle boy is dressing up as his personal superhero this Halloween --- his surgeon. Landon Browne was born deaf, but received his first cochlear implant when he was only 9 months old, ABC News reported. Dr. Jay Rubinstein performed the operation seven years ago, and the professor of Otolaryngology-Head and Neck Surgery at the University of Washington also performed a second implant surgery this summer. As a result, Browne decided he wanted to emulate his hero this Halloween. Browne gave his costume a test run at the hospital on Wednesday. "I'm pretty smart," Landon told ABC News affiliate KOMO-TV . "I don't mean to be not humble." Rubinstein said that Browne has become an important aspect of his research into cochlear implants and his attempts to help those patients hear music more clearly, ABC News reported. "I'm very grateful for him for all the effort he's made on our behalf," said Rubinstein. "For him to do this makes it clear he feels the same way." Browne's mother said she hopes her son will be able to hear music more clearly in the future, especially because his father is a musician. "I completely got goose bumps, because who would want their child to not experience the beauty of music," Alysia Browne said. Brown's family said he has grown into a precocious kid who likes to beat box.
