Can allogeneic bone rhinoplasty last a lifetime?

Allogeneic rhinoplasty, which involves using bone material from another individual for nasal augmentation, is a relatively complex cosmetic surgical procedure. Whether the results of allogeneic rhinoplasty can last a lifetime mainly depends on the surgical technique, the processing method of the allogeneic bone, the patient's immune response, and postoperative care.

If the surgical procedure is performed precisely, allowing for accurate carving and implantation of the allogeneic bone and reducing surgical complications, the success rate and longevity of the allogeneic rhinoplasty can be improved. To minimize the risk of rejection and infection, allogeneic bones usually undergo strict sterilization and antigen removal processes to reduce the likelihood of being recognized by the immune system as foreign material. However, the human immune system may gradually identify and reject the allogeneic bone, leading to resorption or displacement, which can affect the stability of the nasal shape. Postoperative care is also a crucial factor in determining how long the results of allogeneic rhinoplasty can last. Patients need to follow their surgeon's instructions, properly care for the wound, and avoid strenuous activities and trauma to ensure good integration and stability of the allogeneic bone with surrounding tissues.

Although allogeneic rhinoplasty can provide long-lasting nasal shape improvement, the duration of its effects is not fixed but rather influenced by multiple factors. Regular follow-up examinations and possible revision surgeries are necessary to maintain the desired nasal appearance. However, the exact duration of the results must be determined based on the patient's individual circumstances and the surgeon's evaluation.
