Description

Background Art

[0002] The disadvantages of the existing methods for determining the genioplasty osteotomy angle are as follows:

[0003] I. Strong subjectivity:

[0004] The determination of the genioplasty osteotomy angle depends to a large extent on the doctor's personal experience and aesthetic concepts. Different doctors will determine the osteotomy angle based on their own understandings and preferences, which leads to a certain degree of subjectivity and uncertainty in the surgical results. This subjectivity not only affects the consistency of the surgical effect but also may cause patients to be dissatisfied with the surgical results after the operation.

[0005] II. Lack of quantitative standards:

[0006] Currently, the methods for determining the osteotomy angle are mostly based on the doctor's intuitive judgment and feel, lacking objective and quantitative evaluation criteria. This makes it difficult for doctors to accurately determine the osteotomy angle during the operation, thus increasing the surgical risk and uncertainty. At the same time, the lack of quantitative standards also makes it difficult to evaluate and compare the postoperative effects.

[0007] III. Large individual differences:

[0008] There are differences in the facial structures and bone morphologies of each person, which makes the determination of the genioplasty osteotomy angle more complicated. Even if the same surgical method is adopted, there are significant differences in the surgical results of different patients. Such individual differences require doctors to spend more time on facial analysis and surgical planning before the operation to ensure the accuracy and satisfaction of the surgical results.

[0009] IV. High technical difficulty:

[0010] Genioplasty osteotomy surgery is a surgery with relatively high technical difficulty, which requires doctors to have rich experience and excellent skills. When determining the osteotomy angle, doctors need to comprehensively consider multiple factors such as the patient's facial structure, bone morphology, and soft tissue distribution, which makes the operation process complicated and challenging. If the doctor's technical level is not high enough or the experience is insufficient, it will lead to unsatisfactory surgical results or complications.

[0011] V. Difficult to predict the postoperative effect:

[0012] Due to the existence of the above disadvantages, it is difficult to accurately predict the effect after genioplasty osteotomy surgery. Even if doctors conduct detailed facial analysis and surgical planning before the operation, various factors during the operation may cause the surgical results to deviate from the expectations. This may create a gap between the patient's expectations of the surgical effect before the operation and the actual results after the operation, thus affecting the patient's satisfaction and the surgical success rate.

[0047] The present application will be further described in detail below with reference to the drawings and embodiments. Through these descriptions, the features and advantages of the present application will become more clearly defined.

[0048] The special term "exemplary" here means "serving as an example, embodiment, or illustrative". Any embodiment described as "exemplary" here does not have to be interpreted as superior to or better than other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0049] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0050] To facilitate the understanding of the method and system for calculating the mentoplasty osteotomy angle provided by the embodiments of the present application, the application scenario thereof will be described first. The method and system for calculating the mentoplasty osteotomy angle provided by the embodiments of the present application are used to realize the standardization of determining the mentoplasty osteotomy angle. The disadvantages of the existing methods for determining the mentoplasty osteotomy angle are as follows: First, strong subjectivity: The determination of the mentoplasty osteotomy angle depends to a large extent on the personal experience and aesthetic concepts of doctors. Different doctors will determine the osteotomy angle according to their own understandings and preferences, which results in great subjectivity and uncertainty in the surgical results. This subjectivity not only affects the consistency of the surgical effect but also may make patients dissatisfied with the surgical results after the operation. Second, lack of quantitative criteria: At present, the methods for determining the osteotomy angle are mostly based on the intuitive judgment and feel of doctors, lacking objective and quantitative evaluation criteria. This makes it difficult for doctors to accurately control the osteotomy angle during the operation, thereby increasing the surgical risk and uncertainty. At the same time, the lack of quantitative criteria also makes it difficult to evaluate and compare the postoperative effects. Third, large individual differences: There are differences in the facial structures and bone morphologies of each person, which makes the determination of the mentoplasty osteotomy angle more complicated. Even if the same surgical method is adopted, there are significant differences in the surgical results of different patients. Such individual differences make doctors spend more time on facial analysis and surgical planning before the operation to ensure the accuracy and satisfaction of the surgical results. Fourth, high technical difficulty: The mentoplasty osteotomy operation is a highly technical operation that requires doctors to have rich experience and excellent skills. When determining the osteotomy angle, doctors need to comprehensively consider multiple factors such as the patient's facial structure, bone morphology, and soft tissue distribution, which makes the operation process complicated and challenging. If the doctor's technical level is not high enough or lacks experience, it will lead to unsatisfactory surgical results or complications. Fifth, the postoperative effect is difficult to predict: Due to the existence of the above disadvantages, it is difficult to accurately predict the postoperative effect of the mentoplasty osteotomy. Even if doctors conduct detailed facial analysis and surgical planning before the operation, various factors during the operation may cause the surgical results to deviate from the expectations. This creates a large gap between the patient's expectations of the surgical effect before the operation and the actual results after the operation, thereby affecting the patient's satisfaction and the surgical success rate. For this reason, the embodiments of the present application provide a method and system for calculating the mentoplasty osteotomy angle to realize the standardization of determining the mentoplasty osteotomy angle. The following will be described in detail with specific drawings by way of examples.

[0062] Enhance facial three-dimensionality: A reasonable design of the osteotomy angle of the chin can enhance the facial three-dimensionality, making the facial lines smoother and more natural.

[0063] III. Reduce surgical risks

[0069] In summary, constructing a calculation model for the osteotomy angle of the chin and using this model for surgical design can accurately customize plastic surgery plans, optimize the facial contour, reduce surgical risks and improve patient satisfaction; it has broad application prospects and important clinical significance.

[0070] In a specific feasible implementation plan, according to the aesthetic proportion relationship and aesthetic plane standard, the steps of constructing the calculation model for the osteotomy angle of the chin specifically include:

[0071] Calculate the length value of the chin and the anterior movement amount of the chin according to the aesthetic proportion relationship and aesthetic plane standard;

[0072] Construct the calculation model for the osteotomy angle of the chin according to the calculated length value of the chin and the anterior movement amount of the chin.

[0076] In a specific feasible implementation plan, the aesthetic proportion relationship includes the proportion of the length and width of the face, the proportion of the three facial regions, and the proportion of the upper and lower chin-lip heights.

[0077] Specifically, refer to Figures 3 to 7, given X and Y, plan W and Z, and determine the genioplasty osteotomy angle; where X is the original length of the chin, Y is the original height of the chin, W is the chin length value, and Z is the anterior movement amount of the chin.

[0078] Take Figure 7 as an example for illustration. Given that angle C = 90°, find angle B.

[0079] According to the sine and cosine formulas,

[0080] SIN B = b (opposite side) ÷ c (hypotenuse);

[0081] COS B = a (adjacent side) ÷ c (hypotenuse);

[0082] Therefore, the lengths of a and b are obtained as:

[0083] a = w;

[0084] b = (Z - X) ÷ 2;

[0085] Both are known planning data.

[0086] According to the Pythagorean theorem,

[0087] c 2 = a 2 + b 2 ;

[0088] The length of side c can be obtained.

[0089] Then SIN B or COS B can be calculated.

[0090] Then, through the calculated SIN B or COS B, use the arcsine function or arccosine function to obtain angle B, and adding 90° is the obtuse angle.
