“…Due to occlusal and functional worsening, a new approach was necessary to install a thicker osteo-synthesis system associated with an iliac crest graft to fill the bone gaps, enabling the achievement of the treatment goals with occlusal stability, allowing recovery of all masticatory physiology and visualization of complete neoformation bone between bone fragments confirmed by imaging exams. Despite the challenges of the re-operation related to the initial surgery, the literature states that this technique is effective for pseudoarthrosis treatment, with a higher success rate,3,5,6 finding also confirmed in our study.…”

“…Pseudoarthrosis, or nonunion, after orthognathic surgery is characterized by the formation offibrous tissue instead ofosteoid material in the interfragmentary gaps 7. Symptoms such as pain, malocclusion, and bone mobility usually appear late and can go unnoticed when periodic monitoring is not performed 5. As a consequence of these factors, few reports of pseudoarthrosis are found in the literature,3,5,8 making many aspects of this complication, such as etiology, treatment, and incidence, remain controversial.…”

: Orthognathic surgery to treat dentofacial discrepancies has become an increasingly common elective procedure in sur-gical practices. Despite its numerous advantages such as improved aesthetics and masticatory and respiratory function, some complications and unfavorable results can be observed. Pseudoarthrosis after orthognathic surgery is a rare complication and is little reported in the literature. Pseudoarthrosis is characterized by an increasing occlusal worsening associated with bone mobility and pain. Due to the low incidence of pseudoarthrosis, it is necessary to study its involvement to elucidate its etiology and treatment. The aim of this work was to report a clinical case of bilateral mandibular pseudoarthrosis after orthognathic surgery, where multiple interventions and prolonged treatment time were necessary until the case was concluded. The precise diagnosis associated with the choice of the most effective treatment based on the literature proved to be essential for the management of this complication.

Unfavourable outcomes are part and parcel of performing surgeries of any kind. Unfavourable outcomes are results of such work, which the patient and or the clinician does not like. This is an attempt to review various causes for unfavorable outcomes in orthognathic surgery and discuss them in detail. All causes for unfavorable outcomes may be classified as belonging to one of the following periods A) Pre- Treatment B) During treatment Pre-Treatment: In orthognathic surgery- as in any other discipline of surgery- which involves changes in both aesthetics and function, the patient motivation for seeking treatment is a very important input which may decide, whether the outcome is going to be favorable or not. Also, inputs in diagnosis and plan for treatment and its sequencing, involving the team of the surgeon and the orthodontist, will play a very important role in determining whether the outcome will be favorable. In other words, an unfavorable outcome may be predetermined even before the actual treatment process starts. During Treatment: Good treatment planning itself does not guarantee favorable results. The execution of the correct plan could go wrong at various stages which include, Pre-Surgical orthodontics, Intra and Post-Operative periods. A large number of these unfavorable outcomes are preventable, if attention is paid to detail while carrying out the treatment plan itself. Unfavorable outcomes in orthognathic surgery may be minimized If pitfalls are avoided both, at the time of treatment planning and execution.
