All surgeries have some risks. If performed by a competent surgeon, complications are infrequent and minor. The vast majority of these operations go perfectly well with excellent results and happy patients. All patients will experience some scratchy sensation for a few days after the surgery.
Any surgery has some risk of bleeding and infection. Wound disruption and heavy scarring are also possible. These are very rare in this surgery, and other complications are even less common. For some of these complications, a touch-up procedure might be necessary for correction. Dr. Tandon will discuss any possible risks with you before surgery is done, and answer all of your questions.
