A ansiedade e a preocupação dos pacientes decorrentes da obscuridade das informações relacionadas ao procedimento cirúrgico ortognático despertou o desenvolvimento deste estudo, que objetivou identificar as necessidades de informação do paciente sobre o cuidado pós-operatório da cirurgia ortognática. Trata-se de pesquisa exploratória qualitativa, que utilizou como método de coleta de dados o grupo focal com pacientes em pós-operatório de cirurgia ortognática de um ambulatório de cirurgia e traumatologia bucomaxilofacial. Os dados foram submetidos à análise de conteúdo para identificação das falas significativas para o alcance do objetivo. Entre os assuntos mais abordados, destacaram-se o longo tempo de recuperação e as dificuldades relacionadas à alimentação, higienização e redução dos sinais e sintomas pós-operatórios. Comentários relacionados à autoimagem e à satisfação com os resultados da cirurgia apontam para a necessidade de exploração em futuros estudos.

Complete removal of hypertrophied inferior nasal turbinates may favour the occurrence of the empty nose syndrome (ENS). Some surgeons recommend partial turbinectomy in order to minimize the occurrence of ENS. However, little is known about whether total removal of the inferior nasal turbinate is associated with ENS. The aim of the present study was to evaluate the effects of total turbinectomy and septoplasty on the breathing of individuals undergoing orthognathic surgery with maxillary impaction. A total of 20 individuals participated in this cross-sectional study, in which the relationship between exposure (maxillary orthognathic surgery) and outcome (nasal respiratory function) was investigated. The Empty Nose Syndrome 6-Item questionnaire and Nasal Obstruction Symptom evaluation scale were applied to investigate the ENS. A three-dimensional assessment of the piriform opening was performed pre- and postoperatively by computed tomography in order to measure the volume of the nasal cavities using the Dolphin Imaging software. ENS was detected in 35% of patients, while 13 reported improved breathing. Symptoms of ENS such as dryness, suffocation, nose feels too open and nasal crusting were mentioned. The mean nasal cavity volume was 7477.15 mm³ greater in the initial evaluation (p<0.05). In summary, the occurrence of ENS does not constitute an absolute contraindication of total turbinectomy, a procedure that contributed to the improvement of airway permeability.

Eye-tracking studies explore visual photographic perception from a variety of perspectives, as a renewed approach to traditional assessment. The present article aimed to evaluate the esthetic visual perception of laypeople on the lower third of the face, simulating an Angle Class I, Class II, and Class III profile. Class I (straight profile), Class II (mandibular retrognathism), and Class III (mandibular prognathism) were analyzed through a series of edited profile photographs, in the magnitudes of 2.5 mm 5mm, and 7.5 mm in male and female subjects. The changes occurred only in the lower third of the face and the maxilla remained unchanged. The scanning trace of 60 laypeople raters (30 males and 30 females) were recorded using the eye-tracker hardware and the Ogama software to visualize the ocular movement in areas of interest. Heat maps and dots maps were generated by the software to evaluate the main regions of ocular fixation. Each subject was asked to score the attractiveness of each profile separately using a visual analog scale. One-way ANOVA was performed to identify statistically significant differences (p < 0.05). Regarding the heatmaps, the perception of lip called great attention from the laypeople. Statistical difference was found for a complete-time of fixation between Class I and Class II 5mm (p=0.029) for the female model, Class I and Class III 7.5mm (p=0,028), Class I and Class II 7.5mm (p=0,013) for the male subject, where the images with the alterations called more attention than with the Class I for both models. As for attractiveness scores, Class, I for the female and male models were considered more attractive. The lower and upper lip demonstrated an influence on profile perception for alterations of 7.5mm in class III for males and females. Class I was considered more attractive for both models. More aged evaluators tented to give higher grades for attractiveness.

Facial asymmetry can result from numerous types of diseases, such as: trauma (edema, emphysema, hematomas) and serious infectious processes that generate volumetric increases in the face quickly and noticeably. On the other hand, the development of cysts and tumors, changes in development/growth of both hard and soft tissues, are slower processes and consequently perceived when there is a significant change. Osteochondroma (OC), one of the intraosseous lesions can be defined as a protrusion of bone cartilage that arises from the outermost surface of the affected bone. The objective of this work is to describe a complex, but stable and satisfactory treatment methodology with good stability and satisfactory aesthetic-functional results. Discussion directly related to therapeutic modality, cost-effectiveness of localized treatment compared to combined treatment, risks, benefits and the like. The results show images that make it possible to verify the accuracy and applicability of virtual planning in the correction of deformities associated with the expertise of surgeons with great experience in surgical treatments, ending with a satisfactory result for the patient and team.

To demonstrate the efficiency of Bimaxillary Orthognathic Surgery in patients with Obstructive Sleep Apnea Syndrome. To this end, we proceed to the clinical case of a patient with retrognathism, with complaints about difficulties to sleep, night snoring, difficulty breathing and little disposition throughout the day. She also complained about her facial appearance. Through intra-oral, extra-oral clinical examinations and confirmed by imaging exams, it is thus diagnosed as Angle class II. The treatment with orthognathic surgery is pertinent to patients who exhibit facial imperfections, including the teeth and the skeleton of the face. being remedied only with orthodontic treatment. Because the deficiency to be solved is in the jaw and / or maxilla and not only in the dental positioning. Thus, it is observed that the results obtained through surgery with osteotomies and traction myorhaphy of the suprahyoid muscles become efficient. It is concluded that when well planned and indicated, orthognathic surgery does not become an invasive procedure, but effective in the treatment.

Objective: To evaluate the quality of life and degree of satisfaction of patients submitted to orthodontic-surgical treatment after orthognathic surgery. Methodology: thirty ortho-surgical patients responded two specific questionnaires (Portuguese versions) -one on quality of life (Orthognathic Quality of Life Questionnaire – OQLQ) and another on degree of satisfaction (Post-Surgical Patient Satisfaction Questionnaire - PSPSQ) - and responded to a form containing socioeconomic-educational data and post-surgical time. The associations between the independent (age, gender, civil status, educational level, family income and post-surgical time) and dependent variables (quality of life and degree of satisfaction) were submitted of the Mann-Whitney test (significance of 5%). Spearman correlation test (significance of 5%) was applied to analyze the relationship between the dependent variables. Results: The OQLQ had a mean of 16.17 (±19.17) and median of 12, characterizing the sample with a good quality of life profile. The PSPSQ obtained a mean of 26.6 (±1.99) and median of 27, evidencing a high degree of satisfaction after surgical treatment. There was a significant correlation between the OQLQ x PSPSQ of the moderate negative type (0.40 to 0.69) and there was no significant correlation between socioeconomic-educational variables and post-surgical time with OQLQ and PSPSQ. Conclusion: The study indicated that the high satisfaction with the surgical treatment is directly related to the good quality of life presented after the treatment, demonstrating the importance of the ortho-surgical treatment.

Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is the most common sleep disorder in the population and is characterized by five or more episodes of partial or total upper airway (UA) obstruction during sleep, for a period equal to or greater than 10 seconds. The most common reported symptoms are daytime sleepiness, night snoring, restless sleep and excessive fatigue, which directly interfere at the individual's quality of life. This work aims to approach orthognathic surgery as a treatment option for Obstructive Sleep Apnea-Hypopnea Syndrome. It is a literature review where it was performed a search related to the topic covered at the databases SCIELO (Scientific Electronic Library On-line), PubMed, Science Direct and Google Scholar, in the period from 2013 to 2020. OSAHS is a serious public health problem, and it is also up to the dental surgeon to diagnose and treat, being the advancement maxillomandibular orthognathic surgery a safe and effective alternative.

Introduction: The most common complication resulting from bilateral sagittal split osteotomy in orthognathic surgery to reposition the mandible in relation to the skull base is the possible damage to the lower alveolar nerve, causing paresthesia in the region of the lower lip and tip of the chin. The incidence of paresthesia after performing this technique is 85-87% of cases. Throughout history, many treatments aimed at restoring sensorineural function in this area have been reported. One of the fields that is currently growing is low power laser therapy. Objective: The aim of this study was to review the literature on the use of laser therapy in the postoperative period of bilateral sagittal osteotomies of the mandibular branch. Methodology: The articles were selected using the PubMed database. For inclusion criteria of the article it should be published in English and whose adopted methodology would allow obtaining significant evidence. Results: The main results found were that low-level laser therapy is effective in helping to control postoperative pain as well as speeding up the repair and regeneration process of tissues, especially nerves, thus reducing postoperative paresthesia. Conclusion: It is concluded that low-power laser therapy is beneficial in accelerating tissue repairs, bringing greater comfort to the patient. However, further studies and follow-up are needed in this area in order to establish a complete application protocol.

This paper aims to provide a bibliometric analysis of the literature on oral and maxillofacial surgery, comparing different databases and discussing the advantages, disadvantages, and specific features of each one. A bibliographical search for oral and maxillofacial surgery literature was conducted on Pubmed, Scopus, Web of Science, Dimensions, SciELO, LILACS, and Google Scholar. Seven different search strategies were used on each database. VOSViewer and Microsoft Excel were used for tabulation and data visualization. Some statistical tests were performed with a 95% confidence interval, which was considered significant. A table comparing the number of articles obtained during seven different literature searches was created. A correlogram created in RStudio showed the correlation between the number of articles in the different databases evaluated. The functionalities of each database were compared. It is recommended to use more than one database when searching for literature related to surgery. Among the analyzed databases, PubMed stands out for its functionalities, precision, and quantity of available articles.

The early benefit protocol in orthognathic surgery or surgery-first approach (SFA) has as its main idea the surgical approach before previous orthodontic preparation, in contrast to the idea of ​​the traditional approach, which advocates a preoperative orthodontic treatment, which may present more uncomfortable for the patient when compared to surgery-first because it takes a very long time, discomfort during the orthodontic treatment, and the patient may present psychosocial problems related to the delay in the resolution of the main complaint and/or even the aggravation of such complaint due to attenuation of facial asymmetry resulting from the correct position of the teeth in the arches, and possible intra-oral complications related to hygiene and oral health with the use of intra-oral orthosis. The surgery-first approach is based on initially improving facial aesthetics, which is usually the patient's main complaint, and then moving on to the second stage of occlusal movement and alignment. This literature review aims to evaluate and compare the findings regarding the conventional protocol. and the suggestion-first protocol. A MEDLINE search. Inclusion criteria were 1) human study and 2) orthognathic surgery with surgical-first approach or equivalent, and 3) three-dimensional planning with virtual flow in a suggestion-first approach. After an evaluation of the contemporary literature, it was concluded that this approach is positive when related to treatment time, patient's quality of life, post-surgical orthodontic time and occlusal stability. Overall, the SFA achieved optimal results comparable to the conventional protocol regarding treatment success.
