Skeletal jaw disorders are alterations in the growth or position of the bones that form the upper jaw (maxilla) and the lower jaw (mandible). These changes can affect chewing, speech, breathing, and even facial aesthetics, influencing the quality of life of those who experience them.
Orthognathic surgery-together with a multidisciplinary approach—is the treatment of choice to correct these problems, restoring facial harmony and proper oral function.
Orthognathic surgery is a procedure designed to correct skeletal discrepancies of the jaws by repositioning, advancing, setting back, or rotating facial bones. Its main goal is to achieve a functional and aesthetic balance, improving both the bite and facial symmetry. This treatment requires meticulous planning and the involvement of different specialists, as it includes several stages ranging from diagnosis to final rehabilitation.
The first step in treatment is the initial consultation with the orthodontist or maxillofacial surgeon. During this stage, the professional performs a thorough clinical evaluation, including a review of the patient’s medical and dental history and the main reasons for consultation. Additional tests are requested—such as X-rays, CT scans, and photographs—to identify the type and magnitude of the skeletal alteration.
Functional aspects (chewing, breathing, speech) and aesthetic concerns are also assessed, since treatment will impact all of these areas. Clear communication between the medical team and the patient is essential to understand expectations and design a plan tailored to individual needs.
Before any surgical intervention, it is essential to prepare tooth position with orthodontics. Pre-surgical orthodontics aims to align and level the dental arches, eliminating dental compensations that can mask the true skeletal problem. This process may take several months—or even years—depending on case complexity.
During this period, the orthodontist adjusts brackets or aligners and schedules regular check-ups to monitor progress. Patient cooperation with appliance use and oral hygiene is key. Proper dental alignment will facilitate surgery and optimize functional and aesthetic results afterward.
Technology plays a central role in planning. Today, virtual planning software is used to simulate—down to millimetric precision—the bone movements required and to predict aesthetic and functional outcomes. Through 3D scanning and the integration of radiologic images, specialists can visualize different surgical scenarios and choose the best option for each patient.
This stage includes the creation of customized surgical guides, which are used during the procedure to ensure the planned movements are carried out accurately. Virtual simulation is also a valuable tool to communicate expected changes to the patient and align expectations with achievable results.
Orthognathic surgery is performed in an operating room under general anesthesia. It involves making controlled cuts (osteotomies) in the jaw bones to reposition them according to the prior plan. The bones are then fixed in the new position with titanium plates and screws, which provide stability and allow progressive healing.
The procedure may involve one or both jaws, depending on the diagnosis. In some cases, techniques are combined to address associated problems such as sleep apnea or bite disturbances. Surgery time varies by complexity but typically ranges from two to five hours.
During hospitalization—which generally does not exceed two or three days—the medical team manages pain and swelling and monitors proper early healing.
In recent years, intraoperative navigation has revolutionized the precision of orthognathic surgery. These are computerized systems that guide the surgeon in real time during the procedure, ensuring bone movements match the plan exactly.
This technology—similar to a GPS for surgery—minimizes the margin of error and reduces the risk of complications. It also helps resolve complex cases and enables documentation of the entire process, contributing to safety and treatment quality.
The postoperative period is crucial for recovery. In the first days, patients may experience swelling, discomfort, and difficulty speaking or eating. The medical team typically recommends a soft diet, pain relievers and anti-inflammatories, as well as specific oral hygiene measures.
Close follow-up helps detect and treat potential complications early, such as infections or healing problems. Over the following weeks, patients gradually resume daily activities, always under professional supervision.
The orthodontist resumes treatment for minor adjustments and to ensure long-term bite stability. This post-surgical orthodontic phase often lasts several months.
Once the surgical and orthodontic phases are complete, rehabilitation begins. This may include speech therapy, physiotherapy to restore jaw mobility, and reinforcement of healthy habits. The goal is to achieve optimal chewing, breathing, and speech function, as well as to consolidate aesthetic outcomes.
Long-term follow-up is essential: periodic check-ups help monitor stability, prevent relapse, and maintain oral health. In some cases, additional treatments may be needed, such as dental implants or prosthetic restorations.
The success of treatment for skeletal jaw disorders depends largely on the coordinated work of a multidisciplinary team. Specialists in orthodontics, maxillofacial surgery, anesthesiology, speech therapy, physiotherapy, restorative dentistry, and—at times—psychology or nutrition may be involved.
Each professional contributes a complementary perspective that strengthens the approach and ensures comprehensive patient care. Communication between specialties is essential to anticipate challenges, prevent complications, and optimize results at every stage.
In addition, psychological support can be crucial to help patients cope with the physical and emotional changes involved, promoting adaptation and overall well-being.
Correcting skeletal jaw discrepancies with orthognathic surgery offers significant functional, aesthetic, and emotional benefits. Patients often experience notable improvements in chewing, breathing, speech, and facial harmony, positively impacting self-esteem and quality of life.
It is essential for patients to maintain open communication with the treating team, understand each stage of the process, and participate actively in recovery. Commitment and mutual trust are key to achieving the best results and enjoying a full, healthy life without limitations.
