SummarySkeletal malocclusions may be due to disturbances in the growth of the mandible or maxilla. In most cases, discomfort is the result of tooth-to-tooth malocclusion or tooth-to-softtissue contact. Currently, in veterinary medicine, these problems are treated palliatively. In humans, orthognathic surgery is indicated to correct severe skeletal malocclusions, offering aesthetic and functional benefits to the patients. This research evaluated the effects of an intra-oral mandibular sagittal split osteotomy in 20 dog cadavers with skeletal malocclusion. After sagittal osteotomy and mandibular repositioning, the osteotomies were fixed with titanium mini-plates and 1.5 mm diameter screws or 1.5 mm bicortical screws. The statistical analysis revealed a significant occlusion difference in the treated cadavers (Wilcoxon test, p <0.05). In 19/20 cadavers there was correction of the angular osteotomy while the mandibular alveolar vessels and nerve were preserved during osteotomy and fixation in all cadavers. In conclusion, intra-oral mandible sagittal osteotomy allowed correction of malocclusion in cadavers. However, it would be important to prepare a preoperative orthodontic-surgical treatment plan to obtain a satisfactory occlusion during the surgery in clinical patients.

Background: The number of patients undergoing combined orthodontic treatment and orthognathic surgery is increasing. Hence, this study aimed to examine the impact of combined orthodontic and orthognathic treatment procedures on the life quality of patients with skeletal malocclusion. Materials and methods: 15 patients who had to undergo combined orthodontic and orthognathic treatment procedures were subjected to 22-item Orthognathic Quality of Life Questionnaire customised for the study. The questions were grouped into 4 domains – aesthethic, awareness, pschyological and social domains. They were assessed in three time lines - rst when they are explained and made aware of the treatment plan (T0), T1 when the orthodontic treatment is almost complete, and the patient is made ready for orthognathic surgery, then 6 months after the completion of the combined orthodontic-orthognathic surgery (T2). Results: Out of 15 patients, 9 were females and 6 were males between the age of 18-25 years. As the treatment progressed changes were noted in the patient's attitude. During T1 signicant change was observed in functional outcome – chewing. At T2 signicant changes were observe in esthetic, functional, social and psychological components (p<0.001). The treatment outcome did create a positive change in the patients by correcting their skeletal and dental abnormalities. Conclusion: The esthetic, functional, social and psychological outcomes of patients who have undergone combined orthodontic and orthognathic treatments are better post operatively.

Introduction: The aim of the study was to assess the effectiveness of surgical treatment of patients with Eagle's syndrome, taking into account both early and late results. Materials and methods: The study group consisted of 15 patients who underwent resection of the styloid process due to Eagle syndrome in the period of 2005-2017. During the follow-up visit, the patients were asked to fill in a post-operative questionnaire that compared the pre-operative symptoms and their severity with the patients' current health condition. The VAS pain scale was used to assess each symptom, and the Laitinen scale was used to assess the quality of life. Data from patients' medical records were also included. The results of the surveys were subjected to statistical analysis. Results: The study showed that in 11 out of 15 cases there was a significant improvement in the level of pain (70.5% on average) and an improvement in quality of life (on average 65%) comparing to the pre-operative condition. The Wilcoxon test for binding pairs, the Mann-Whitney test, the Kruskal-Wallis test and the Spearman correlation coefficient were used in the statistical analysis. There were statistically significant correlations between the recorded improvement rate and the length of the resected styloid process and its setting. Discussion: The study proved that resection of prolonged styloid process from extraoral approach in most cases is an effective method of treatment of Eagle syndrome, that carries low risk of complications.

Society imparts great importance to physical appearance in this modern age. The physical and psycho-social impact of a dentofacial deformity on an individual is often impossible to assess with certainty. A facial deformity can profoundly affect the quality of life and thereby entailing lifelong adjustments. Facial aesthetics affect an individual's confidence and their overall acceptance in society, which in turn has an apparent effect on their quality of life. Corrective jaw surgeries are indicated in cases not amenable to produce acceptable post-treatment results with orthodontics alone. Orthognathic surgery aims to produce a more aesthetic facial appearance and strives to improve stomatognathic functions in the process. WHO defines Quality of Life as- An individual's perception of their position in life in the context of the culture and value systems in which they live and concerning their goals, expectations, standards and concerns. It is a broad-ranging concept affected in a complicated way by the person's physical health, psychological state, level of independence, social relationships, personal beliefs and their relationship to salient features of their environment. The impact of dentofacial deformities on an individual's holistic emotional, physical and social development has been a focus of research for a long time. Several patients reported outcome scales are employed to assess the quality of life and this review aims to discuss the use of these scales as an indicator of successful surgical treatment. At the same time, these scales may serve as a patient education tool because a holistic health indicator is required which considers the psychological well being of the patient along with regards to functional and aesthetic demands before formulating a surgical treatment plan.

Aim: Orthognathic surgery aims to correct facial skeletal deformities and the correct condylar positioning is very important for stable results. The aim of the present study was to verify the occurrence of changes in the postoperative condylar positioning in artificial skulls with a skeletal Class II maxillomandibular relationship submitted to bilateral sagittal split osteotomy when the method of cephalometric data transfer was used. Methods: Ten skeletal Angle class II polyurethane skulls were used with metallic markers in the articular surfaces of the temporomandibular joint and mandibular condyles. The skulls were submitted to preoperative and postoperative cone beam computed tomography before and after the bilateral sagittal split osteotomy. To verify the condylar positioning, measurements between the distances of the markers at the temporal bones and mandibular condyles were taken in the coronal and sagittal views by the DISTANCE tool of the iCat Vision software. All measurements were obtained by one examiner in the preoperative and postoperative CBCTs, tabulated and submitted to statistical analysis by the Wilcoxon test with a level of significance of 5% (p<0,05). After 15 days of the completion of the first data collection, all measurements were redone to determine the random and systematic error by the Intraclass Correlation Coefficient. Results: With the exception of the average of the lateral-medial distance (from the measurements between the medium left markers only), the averages of the anterior-posterior distances (only in the left posterior and lateral right markers) and the vertical average (only in the central markers) showed no statistically significant differences between the preoperative and postoperative distances of the metallic markers. Conclusion: Even when using the method of cephalometric data transfer, variation of the condylar positioning occurred between the preoperative and postoperative periods. This variation occurred only in a few points of the mandibular condyles.

Introduction. The primitive malignant melanoma of nasal mucosa and paranasal sinus is a rare tumor of uncertain etiology, with unpredictable biologic behavior and bad prognosis. Unlike skin melanomas, there are no risk factors and the disease is frequently manifested in older patients, whose clinical otorhinolaryngology complaints are normally non-specific and ranges from nasal obstruction to rhinorrhea and epistaxis. Unfortunately, this disease is diagnosed basically in advanced stages which makes the surgery difficult. Objective. To report a case of primitive malignant melanoma of nasal mucosa, ethmoid and frontal sinuses, that was diagnosed in 2015. It was performed a subtotal resection in another hospital in 24.08.2015, with a large local reccurence. Report. Our patient was a 78-year-old woman with bilateral nasal obstruction, light epistaxis and unilateral rhinorrhea. The ENT, CT and  MRI exams showed a tumour with important, invasion of the nasal cavity structures (billateral nasal bones, left frontal process of the maxilla, the superior midpoint of the nasal septum, bilateral middle and superior turbinates, left ethmoid and bilateral frontal sinuses). The patient was submited for surgery: total macroscopic resection in the combined endoscopic approach; transnasal and modified lateral rhinotomy with titaniul plates reconstruction of the external nose architecture. Conclusions. Malignant melanomas of nasal mucosa are, in general, diagnosed in advanced stages. Their histological characteristics in the mucosa makes difficult the surgical treatment, which is one of the most efficient options, because they are resistant to chemo and radiotherapy. The early diagnosis and a good surgical treatment plan are the best option for this tumor nowadays.

The analysis aims at assessing the current trends in orthognathic surgery. The retrospective study covered a group of 124 patients with skeletal malocclusion treated by one team of maxillofacial surgeons at the University Hospital in Zielona Góra, Poland. Various variables were analysed, including demographic characteristics of the group, type of deformity, type of osteotomy used, order in which osteotomy was performed and duration of types of surgery. The mean age of the patients was 28 (ranging from 17 to 48, SD = 7). The group included a slightly bigger number of females (59.7%), with the dominant skeletal Class III (64.5%), and asymmetries were found in 21.8% of cases. Types of osteotomy performed during surgeries were divided as follows: LeFort I, segmental LeFort I, BSSO, BSSO with genioplasty, LeFort I with BSSO, LeFort I with BSSO and genioplasty, segmental LeFort I with BSSO, isolated genioplasty. Bimaxillary surgeries with and without genioplasty constituted the largest group of orthognathic surgeries (49.1%), and a slightly smaller percentage were one jaw surgeries (46.7%). A statistically significant correlation was found between the type of surgery and the skeletal class. In patients with skeletal Class III, bimaxillary surgeries were performed significantly more often than in patients with skeletal Class II (57.5% vs. 20.0%; p = 0.0002). The most common type of osteotomy in all surgeries was bilateral osteotomy of the mandible modo Obwegeser–Epker in combination with Le Fort I maxillary osteotomy (42.7%). The order of osteotomies in bimaxillary surgeries was mandible first in 61.3% of cases. The longest surgery was bimaxillary osteotomy with genioplasty (mean = 265 min), and the shortest surgery was isolated genioplasty (mean = 96 min). The results of the analysis show a significant differentiation between the needs of orthognathic surgery and the types of corrective osteotomy applied to the facial skeleton.

Background. HFM patients’ reconstruction has always been a challenge for maxillofacial surgeons, and numerous reconstructive techniques have been described. Surgical treatment depends on the patient’s age and contemplates Temporomandibular Joint (TMJ) reconstruction in conjunction with orthognathic surgery, usually necessary following completion of growth to maximize the functional and esthetic results. Distraction osteogenesis had gained popularity as valid alternative in growing patients, but the two primary methods to reconstruct the TMJs involve the use of autogenous, using free or microvascular bone grafts, or alloplastic graft, but there is no widely accepted method. Methods. The increasing use of temporomandibular prosthesis for temporomandibular problems has led us to use them even in HFM. A case of female nongrowing patients with HFM type IIb treated with temporomandibular prosthesis in an all-in-one protocol is presented. Results. Incisal opening, measured with BioPAK system (Bioresearch Inc., Milwaukee, USA), was 21.4 mm in the presurgical period and 32.2 mm after all-in-one procedure, for an increase of 50.5%. Excursive movement to the right side was 2.2 mm in the presurgical period and was 1.5 mm after surgery, for a decrease of 31.8%. Left excursion movement changed from 5 mm to 6.1 mm, for an increase of 22.0%. Conclusions. The TMJ Concepts patient-fitted TJP in conjunction with orthognathic surgery for TMJ and jaw reconstruction is a valid option for patients with HFM.

AbstractIn 1976 Dr. Paul Tessier described numeric classification for rare craniofacial clefts. He first emphasized that a fissure of the soft tissue corresponds, as a general rule, to a cleft of the bony structure. The classification, easy to understand, became widely accepted because the recording of the malformations was simple and facilitated communication between observers.was to present our own experience with treatment of patients with rare facial clefts.Our Department has 11 patients with rare craniofacial clefts under its care. This group includes 8 boys and 3 girls. The patients aged from 2 months to 18 years at the time of the first consultation.In two patients the cleft was median, in seven patients it was one-sided and in two – bilateral. The most common type of cleft was number 6, and the rarest were 2, 3, and 7. All patients underwent surgical treatment.Atypical facial clefts are rare congenital anomalies, however because of functional and aesthetic disturbances they constitute a serious medical and therapeutic problem. Facial clefts are characterized by variable clinical presentation and require individualized treatment plan.
