A prominent plastic surgeon at Boston Children’s Hospital said Tuesday that advocates for preserving a garden at the hospital misused his name in a full-page advertisement for their cause that ran in the Globe.

Dr. John G. Meara, the hospital’s chief plastic surgeon, said that he did not sign a petition to save the Prouty Garden or consent to have his name used in the advertisement that appeared in the paper Tuesday.

“I would have liked to have seen [advocates] vet those names a little more carefully,’’ Meara said in an interview Tuesday night. “I felt like it was unfair for my name to be used.’’

The ad was submitted by the Friends of the Prouty Garden, which launched a website, saveprouty.org, to voice their support for the garden, which is slated to be demolished to accommodate the hospital’s planned expansion of treatment facilities for patients.

In a statement to the Globe, the group said that Meara’s name was mistakenly added because of a “transcription error from a handwritten signature,’’ and that the group would now only accept online signatures to ensure the mistake is not repeated.

“We regret this error and sincerely apologize,’’ the group said. “We will retract his name from any further publishing of this petition. . . . To our knowledge, this is an isolated incident and no other staffers have voiced similar concerns.’’

A Globe executive said the ad met the paper’s standards.

“We require that there is no reader confusion between advertisements and editorial. For paid placement, the ‘paid for by’ is evident, and there are no obvious false claims,’’ Jane Bowman, vice president of marketing and sales development for Boston Globe Media said in a statement. “The Save Prouty ad met these requirements. Both the website and contact information is provided. The content of the ad is the responsibility of the advertiser.’’

Meara’s name appeared in the ad along with dozens of other Children’s staffers beneath a message that said, “We . . . respectfully implore the hospital to revise its plans for this new clinical building to allow Prouty Garden to remain as an enduring therapeutic resource’’ for patients.

Meara said that while he understands the support for the garden, he backs the hospital’s planned expansion.

On its website, the group said that more than 12,000 people have signed their petition to protect the garden.

Prouty Garden is a half-acre of green space that for decades has been a haven for sick children and their families, who have drawn comfort in its meandering paths, colorful azaleas, and stately dawn redwood tree that stands sentry 65 feet over the garden.

In April, the Boston Landmarks Commissionrejected pleas to protect the garden as a landmark, clearing the way for it to be razed to make way for the expansion that will include a new neonatal intensive-care unit with single rooms for families.

Meara said that several months ago, Prouty advocates had circulated a form among hospital employees asking whwhether they supported the garden and the value of green space.

He said he does not recall signing the paperwork, and that it appears the form was the basis for the advertisement, unbeknownst to people who did sign it.

Rob Graham, a spokesman for Boston Children’s, declined to comment when asked whether any additional employees have raised objections about their names appearing in the advertisement. .

“Throughout the process, we’ve tried to engage the entire Boston Children’s community, including those who oppose the [expansion] effort,’’ Graham said. “In the end, we’ll have a stronger Boston Children’s Hospital that will better serve patients and families moving forward.’’
