The aim of the study was to correlate several studies dating from 1997 to 2015 to identify the most effective treatments for mucocele in the frontal sinus (with/without other paranasal sinuses), considering successful outcomes and recurrence. We aimed to conduct a literature review for articles published between 1997 and 2015. For this, we accessed articles in the SciELO database, as well as LILACS, PubMed, and Google Scholar databases. Were identified 32 work-related injuries in the paranasal sinuses; 2 of these were not related to mucoceles or mucopyocele, 4 had no relation to the frontal sinus, 9 were related to the frontal sinus and other paranasal sinuses, 4 were related to mucocele associated with other sinuses, and 13 involved only the frontal sinus. Endoscopic techniques decrease intra- and postoperative morbidity, reducing the operative time, allow a larger view of the lesion and surrounding anatomical structures, and decrease chances of recurrence. Thus, the successful outcomes have been beneficial to both the surgeon and the patient.

Purpose: The present study aims to report the reoperation of an unsuccessful orthognathic surgery with the use of heterogeneous graft and hybrid rigid internal fixation. Case Report: We report the case of V.M.S., a 19-year-old female patient with the main complaint of "crooked chin." The patient revealed that she previously underwent two operations that were conducted by a different team. The first surgery was carried out to correct the dentofacial deformity, while the second one was intended to eliminate a postoperative infection. After a detailed anamnesis, facial analysis, cephalometric analysis with tomography, and examination of gypsum models, we observed mandibular left-handedness and vertical maxillary excess on the right side. In addition to these previously reported problems, there was a nonunion in the region of the sagittal fracture of the left jaw. Results: The patient underwent surgery to correct dentofacial deformity using the Le Fort I maxillary osteotomy technique and bilateral sagittal osteotomy with hybrid rigid internal fixation plus mentoplasty. Conclusion: Six months following the procedure and orthodontic completion, the patient has a satisfactory occlusion and stability of nonunion without the laterognathism in the skeletal and soft tissue profile.

One of the most impressive soft tissue injuries is the facial degloving, normally associated with industrial machines and traffic accidents. This injury is characterized by the separation of the skin and cartilage from the bones, compromising the soft tissues correlated in the trauma area, nerves, and blood vessels. A 28-year-old patient, male, was referred to Araçatuba's Santa Casa Hospital, after a motorcycle accident, hitting his face on the sidewalk. The patient was conscious, oriented, denying fainting and unconsciousness during the accident, and complaining of pain in the nasal region of the face. The suture of wounds was performed using 5-0 absorbable sutures for muscle planes, and reconstruction of the septum and nasal cartilages. The skin was sutured with interrupted stitches using 6-0 nylon. After reducing the edema, a slight increase in alar base was observed. Subsequently, the alar base cinch suture was performed aiming to bring the alar bases to a measure of 34.0 mm in diameter. As a conclusion, the knowledge of the anatomy of the region involved, the healing of tissues, and suture techniques for the facial region process were critical to the successful treatment. The evaluation of the alar base in degloving cases can involve aesthetic features.

Facial asymmetry, following early childhood condylar trauma, is a common complaint among patients who seek surgical treatment. G.D.M., a 27-year-old male patient, sought professional help to correct his cosmetic flaw, caused by a condylar fracture when he was 8-years-old. After the proper orthodontic treatment, he underwent a double jaw orthognathic surgery and, 9 months later, a second one to correct the remaining asymmetry. Two years after this second procedure, the patient is still under surveillance and has no complaints.
