Maybe, but I would be wary of looking for "silver bullet" solutions. Like depression, stuttering is an symptom with many possible causes, and few of the causes are well understood. If a medical examination found a specific physical abnormality that could be corrected with surgery, the that would be great for that person. However, I personally view such a scenario as statistically unlikely. For most of us, the name of the game is learning how to manage the symptoms (a large part of which for me is cultivating a positive head space).
