What pre-operative condition is likely to cause the most unacceptable aesthetic concerns in a maxillary LeFort procedure?

• A. Concave facial profile
• B. Obtuse nasolabial angle
• C. Severe malocclusion
• D. Bone asymmetry

Answer: (B)

In the context of a maxillary LeFort procedure, the aesthetic outcome is heavily influenced by the relationships between facial structures during and after surgical correction. An obtuse nasolabial angle can significantly affect the overall facial aesthetics because it contributes to the perception of mid-facial projection and facial harmony. A nasolabial angle that is too obtuse can result in a flattened appearance of the midface, which is often perceived as less youthful or attractive. This angle is influenced by the positions of the nose and the upper lip in relation to the maxilla, and surgical corrections involving the maxilla can directly affect this relationship. Therefore, if an individual already has an obtuse nasolabial angle, a LeFort procedure aiming to improve other aspects of the maxilla may inadvertently exacerbate the issue, leading to an aesthetically undesirable outcome. In contrast, while other factors such as a concave facial profile, severe malocclusion, and bone asymmetry are important considerations during surgery, they may not have as direct and immediate an impact on the aesthetic perception as an obtuse nasolabial angle. Each of these conditions poses challenges for surgical correction and can affect overall facial harmony, but the nasolabial angle is particularly crucial in facial aesthetics and how others perceive
