A document is presented with the results of various investigations related to data patterns, more specifically those that have been designed with intelligent computational tools. The use of data patterns in medicine is something that has emerged in recent decades and that increasingly presents development alternatives for engineering projects. Various scientific publications are evaluated in this document to relate engineering applications in medicine, and contrast the possible technological impact offered by computational sciences.

Renal cell carcinomas are tumors known for their metastatic potential. The lungs, the lymph nodes, the lungs, the spleen, the adrenal gland and the cervix remain the metastatic sites of predisposition. The symptoms of metastatic lesion may be due to the initial manifestation of renal malignancy. We report in this work a buccal localization of metastases from renal cell carcinoma to clear cells in a patient aged 65 years or less in our department of otolaryngology and cervical-facial surgery.

The development relates to information technology and can be used to process medical images. This task is achieved by the fact that DICOM files containing the results of computed tomography of the human head are subject to correction. They change the color of the pixels at the transition points from black to gray or vice versa, and also replace the black pixel with white. As a result, the percentage of loss of information about small bones is reduced from 22-31 % to 3-5 %, and, therefore, the accuracy of the three-dimensional model of the facial skull of the human head is increased. All this contributes to a significant improvement in the quality of facial surgery.

Abstract Introduction Gender affirming surgery of primary and/or secondary sex characteristics has been shown to alleviate gender dysphoria. A descriptive snapshot of current treatment preferences is useful to understand the needs of the transgender population seeking health care. This study aimed to describe preferences for gender affirming treatment, and their correlates, among individuals seeking health care for gender dysphoria in Sweden after major national legislative reforms. Methods Cross-sectional study where transgender patients (n = 232) recruited from all six Gender Dysphoria centers in Sweden 2016–2019, answered a survey on treatment preferences and sociodemographic, health, and gender identity-related information during the same time-period. Factors associated with preferring top surgery (breast augmentation or mastectomy), genital surgery, and other surgery (e.g., facial surgery) were examined in univariable and multivariable regression analyses in the 197 people without prior such treatment. Main study outcomes were preferences for feminizing or masculinizing hormonal and surgical gender affirming treatment. Results The proportion among birth assigned male and assigned female patients preferring top surgery was 55.6% and 88.7%, genital surgery 88.9% and 65.7%, and other surgery (e.g., facial surgery) 85.6% and 22.5%, respectively. Almost all participants (99.1%) wanted or had already received hormonal treatment and most (96.7%) wished for some kind of surgical treatment; 55.0% wanted both top and genital surgery. Preferring a binary pronoun (he/she) and factors indicating more severe gender incongruence were associated with a greater wish for surgical treatment. Participants with somatic comorbidities were less likely to want genital surgery, while aF with lacking social support were less likely to want internal genital surgery, in the multivariable analyses. Conclusions In this sample of Swedish young adults seeking health care for gender dysphoria, preferences for treatment options varied according to perceived gender identity. Policy Implications The study findings underline the need for individualized care and flexible gender affirming treatment options. The role of somatic comorbidities should be further explored, and support should be offered to transgender people in need. There is an unmet need for facial surgery among aM.

Abstract Background In recent years, aesthetic surgeries have gained significant momentum. A recent audit identified that more than 28,000 cosmetic surgeries were performed in the United Kingdom (UK) in 2018.1. We present an unfortunate case of morbid complications related to the use of malar implant for cosmesis. Case Presentation A 63-year-old Caucasian female presented to the Emergency department with sepsis related to a large painful, tender swelling of the right side of the face. There was discharge of pus from two cutaneous sinuses with additional ectropion/chemosis of the right eye. An orocutaneous communication due to infection/migration of the implant was also noted. The patient reported a history of bilateral malar implants placement three years ago. The patient initially required emergency drainage & subsequent removal of the infected malar implant. Discussion Malar implants provide suitable volume enhancement providing structural and aesthetic benefits including the ‘high cheek bone’ appearance. It is generally considered to be a safe surgical technique with multiple approaches possible to insert the implant. including transoral approach). Spadafora (1971) & Hinderer (1972) first described the use of malar implants for facial augmentation.2,3 Rayess et al.(2017) conducted a 10 year review of complications related to facial implants & noted that 75% of complications related to malar implants were due to infection with 38% of these implants needing removal.4 Conclusion There is a surge in presentations of complications related to cosmetic facial surgery and knowledge of these adverse effects is essential to appropriately manage these patients & their concerns.

Standardisation of image acquisition in Aesthetic Plastic Surgery is critical to accurately communicate changes from cosmetic surgical and non-surgical interventions. Depth of Field, Exposure, Perspective and point of view are the four factors that need to be replicated between photographic sessions to accurately represent these changes without the introduction of photographic bias. Despite many excellent articles on standardisation in plastic surgery photography, no paper fully discusses the four areas that lead to consistency in photographs taken at different times. Depth of field, exposure, perspective and point of view cover all the variables required. We have a system which locks many variables in place, leaving final composition matching to the photographer, the only area that needs intelligent input. There are also misunderstandings in the literature about some of these that need explanation, particularly exposure and perspective.

In order to deeply study oral three-dimensional cone beam computed tomography (CBCT), the diagnosis of oral and facial surgical diseases based on deep learning was studied. The utility model related to a deep learning-based classification algorithm for oral neck and facial surgery diseases (deep diagnosis of oral and maxillofacial diseases, referred to as DDOM) is brought out; in this method, the DDOM algorithm proposed for patient classification, lesion segmentation, and tooth segmentation, respectively, can effectively process the three-dimensional oral CBCT data of patients and carry out patient-level classification. The segmentation results show that the proposed segmentation method can effectively segment the independent teeth in CBCT images, and the vertical magnification error of tooth CBCT images is clear. The average magnification rate was 7.4%. By correcting the equation of R value and CBCT image vertical magnification rate, the magnification error of tooth image length could be reduced from 7.4. According to the CBCT image length of teeth, the distance R from tooth center to FOV center, and the vertical magnification of CBCT image, the data closer to the real tooth size can be obtained, in which the magnification error is reduced to 1.0%. Therefore, it is proved that the 3D oral cone beam electronic computer based on deep learning can effectively assist doctors in three aspects: patient diagnosis, lesion localization, and surgical planning.

AbstractOrthognathic surgery is a complex type of facial surgery that can have a profound impact on a patient's occlusal function and facial aesthetics. Close collaboration between the maxillofacial surgeon and an orthodontist is required, and the surgical team must have a strong foundation in facial analysis and firm understanding of the maxillofacial skeleton to achieve surgical success. Herein, we review the maxillary LeFort I osteotomy as it pertains to orthognathic surgery, with particular attention to the indications, contraindications, preoperative assessment, surgical technique, and possible complications encountered.
