Left Lower Jaw bone cyst. The hospital.

I have a jaw bone cyst of szie 80x30x20 mm. Never had any trauma. Got an xray for wisdom teeth and got to know about the cyst. Got a biopsy done and it's a cyst (not malignant and not ameloblastoma) Doctor is suggesting a surgery where he'll first do root canal for 3 teeth to preserve them (if not done, he will have to remove the teeth and add implants later). After the root canal, he'll remove the cyst and add bone graft. I will be hospitalised for 3-4 days and then will have to take rest for a month. The swelling will be visible for 3 months after the surgery. Bone will take around 8-9 months to grow. I have to get regular OPGs after the surgery. One every six months to check if the cyst is growing back or not. I am getting the surgery done in Bangalore. And then will fly back to Hyderabad for resting for a month or so. I want to know when I can fly back to Hyderabad after the surgery. How many days should I wait after getting discharged from the Hospital.
