Dr. Michael Obeng -- the plastic surgeon who freed Tessica Brown from her head full of Gorilla Glue -- is reaping benefits or his good deed ... he says patient inquiries are up a hundredfold!!!
The Beverly Hills doctor tells TMZ ... since Tessica's procedure last week -- which he did gratis -- his office has received around 5,000 calls asking about all sorts of surgeries -- although most are unrelated to glue removal.
He says callers inquire about the usual stuff -- breast augmentation, butt lifts, vaginoplasty, yada yada. He says one person even wanted oblique muscle removal ... something he doesn't normally do. Point is ... demand is sky-high.
There's more good news for Dr. Obeng too. He explains how he was able to formulate the anti-glue solvent for Tessica on his own with his staff ... and he thinks he's got something special.
He says there's a potential deal in the works with manufacturing companies to produce his "magical solution" for people like Tessica ... who find themselves in a really bad spot with super glue.
If that happens ... multiple businesses could be booming for the doctor.
