Jovan, a patient from France, underwent double jaw surgery (maxillary and mandibular osteotomy) combined with sliding genioplasty at Kangnam Aesthetic Hospital, Ho Chi Minh City. The procedure was performed by Dr. Nguyen Khac Hao (Dr. Edward Nguyen), Head of the Maxillofacial Surgery Department.
For many people considering jaw surgery, one of the greatest concerns is not only the operation itself but also the recovery process—particularly the possibility of prolonged numbness in the lips or chin and the ability to eat and chew normally afterward.
Jovan shared the same concerns. Before deciding to undergo surgery, he researched common postoperative effects and learned that temporary numbness around the lips and chin may occur because this area is closely associated with the sensory branches of the inferior alveolar and mental nerves.
He chose to undergo a consultation at Kangnam Aesthetic Hospital, Ho Chi Minh City, where the Department of Maxillofacial Surgery evaluated his condition before recommending an appropriate treatment plan.
Note: Temporary numbness after orthognathic surgery is a recognized postoperative response. The severity and duration of sensory recovery vary among individuals depending on the preoperative condition, surgical technique, and each patient’s healing response.
Jovan was examined and treated by Dr. Nguyen Khac Hao (Dr. Edward Nguyen), Head of the Maxillofacial Surgery Department at Kangnam Aesthetic Hospital, Ho Chi Minh City.
During the consultation, the surgeon assessed the anatomy of the maxilla, mandible, dental occlusion, and lower facial proportions to develop an individualized surgical treatment plan.
Following the evaluation, Jovan was recommended to undergo double jaw surgery involving both the upper and lower jaws, combined with sliding genioplasty, to correct the skeletal jaw relationship, improve occlusion, and achieve better overall facial balance.
According to Kangnam’s treatment protocol, surgical planning may incorporate advanced technologies such as AI Face Design surgical simulation software and specialized orthognathic surgical techniques to support treatment planning and improve surgical precision.
For Jovan’s case, the surgeon not only explained the surgical procedure in detail but also provided comprehensive counseling regarding the recovery process, particularly the expected return of sensation in the lips and chin following surgery.
Note: Treatment recommendations are based on each patient’s clinical examination and are individualized. The same treatment approach may not be appropriate for every patient.
According to Jovan, his recovery progressed in stages:
These recovery milestones reflect Jovan’s individual experience and should not be considered typical recovery timelines for all patients.
According to Kangnam’s postoperative care protocol, patients undergoing orthognathic surgery are instructed to attend scheduled follow-up appointments so that the surgeon can monitor bone healing, occlusal stability, and postoperative recovery throughout the healing process.
Note: Recovery time varies depending on individual anatomy, the extent of the surgical procedure, postoperative care, and adherence to the surgeon’s instructions.
