On average, how long is the wait for surgery after a consultation?

This is largely dependent on how busy the office is. There also might be some delays if medical clearance is necessaryprior to surgery. This timeframe might vary depending on the time of year as well.  

It really depends on the surgeon's availability and the availability of the OR that your procedure will be done in. Most busy places will be booking at least 4-6 weeks in advance. Hope that helps!
