Asian rhinoplasty using rib cartilage. How long would it take to heal?

For the most significant change in Asian rhinoplasty, rib cartilage is the best choice for a number of reasons.  The rib and chest will be somewhat sore for the first 4-5 days after surgery, and sutures are removed a week after surgery.  By the second week, most of this soreness has resolved and patients may resume light exercise after 2 weeks.  At this point the incision line is typically well-healed.  By 4 weeks full exercise may resume.  A 2 cm linear scar hidden in the crease below your breast is all that remains by this point.  The incision for rib cartilage harvest is typically smaller and more medially placed than the incision for breast augmentation, and should not affect it.  Nearly a third of my female patients have had breast augmentation, and the rib harvest is performed entirely below the breast, and does not interfere with the implant or breast at all.  

Costal cartilage provides great grafting material. However, if you are concerned about healing from the extra incision, perhaps you would benefit from a small synthetic dorsal implant. They have been used successfully and safely in many patients.

Rib cartilage for Asian Rhinoplasty is a great way to build a great nose without synthetic implants.  However, it is not necessarily the first line for autogenous reconstruction.  I would recommend septum (if there is enough) and ear cartilage along with diced cartilage and fascia for the bridge.  There are many techniques that can get you a great result.  Be sure to explore them all so you can make a great choice.
