Treatment and complications of orbito-zygomatic fractures

The aim of the present study was to analyze the etiology, type and treatment employed in the orbito-zygomatic fractures (OZ). Also, postoperative complications are described and correlated with the type of treatment used. Fifty patients with OZ fractures were evaluated. Orbital fractures in which the zygomatic bone was not involved were excluded. Epidemiologic data and characteristics of treatment such as the type of material used for osteosynthesis, number of anatomical sites on which rigid internal fixation (RIF) was applied, surgical approaches and associated complications were recorded. The main causes of trauma were motorcycle and bicycle accidents, constituting 52% of the sample. The osteosynthesis system used was the 2.0 mm, except in four patients in whom the 1.5mm system was used for fixation at the infra-orbital rim. A total of 18% of the patients required reconstruction of the internal orbit and in all cases titanium mesh was used. 46% of the patients received RIF in three anatomical sites, most in the fronto-zygomatic suture, infra-orbital rim and zygomatic-maxillary buttress. The most frequent complication was paresthesia of the infra-orbital nerve (34 patients, 68%). Other findings were also discussed with the intent of better understanding the treatment of the OZ fractures.

Dificuldades relatadas por estudantes de odontologia diante de procedimentos relacionados à periodontia

Objective: This study aimed at evaluating the difficulties reported by last-year dentistry course students regarding basic and surgical periodontal procedures. Methods: A proposed questionnaire with 24 questions, 14 related to basic periodontal procedures and 10 to surgical procedures, was applied to 45 undergraduate students with jobs involving these procedures, during the practical activities of the Integrated Clinic Discipline, a compulsory subject in the curriculum of the course, taught to last-year students. Students were asked about their own perceptions of the difficulties in implementing the various steps related to the treatments. The degree of individual difficulty was determined according to the Likert scale: 0 = none, 1 = mild, 2 = moderate, 3 = high, 4 = very high. Exploratory analysis of data was applied, and the difficulty level was also dichotomized into none to mild (scores 0 and 1) and moderate to very high (scores 2–4). Results: Regarding the basic periodontal treatment, bone level probing was the procedure with the highest number of student difficulties (57.5%). As for the difficulties reported by students regarding the stages of periodontal surgery, only the procedures related to anesthesia and suture removal had no report of doubts. Conclusion: Periodontal surgery was the procedure involving the most prevalent questions reported as moderate to very high, and the indication for the most suitable surgical technique was the stage with the highest percentage of questions (66.6%) among the undergraduates.

End-to-side loop neurorrhaphy: axonal comparative stereological study

Accidents or diseases can affect the peripheral part of the nervous system, which raises clinical and surgical therapies, among others. In this context, the technique of end-to-side neurorrhaphy is a treatment option, yet its modification loop needs some additional efficacy studies. The purpose of this study was to compare, among rats, stereological results (axons volume density) after end-to-side neurorrhaphy and after end-to-side loop neurorrhaphy. Thirty Wistar rats were used, divided into six groups (five animals per group), consisting of two control groups (for the fibular and tibial nerves), two study groups for the fibular nerve (one with an end-to-side neurorrhaphy, and the other with an end-to-side loop neurorrhaphy) and two study groups for the tibial nerve (with an endto- side neurorrhaphy and the other one with an end-to-side loop neurorrhaphy). After 180 days, all groups were sacrificed for axonal stereological analysis (volume density) in distal nerve stumps. There was significant maintenance of neuronal-axonal density in the distal stumps to neurorrhaphy (p< 0.005) compared with the normal stumps. The end-to-side loop neurorrhaphy is a therapeutic option as suture technique after complete nerve section, in order to restore most of the axonal functional integrity.

Supratarsal approach to treatment of zygomatic complex fractures

Many incisions have been described for approaches to zygomatic fractures. Precise repositioning of zygomatic complex fractures is difficult. The traditional approach is through an eyebrow incision, but it can produce a scar that causes aesthetic and psychological problems for the patient. We describe the supratarsal fold approach to expose the frontozygomatic suture and to reduce small displacements of frontal sinus anterior wall; it gives good access and excellent aesthetic results.

Ferimentos faciais: relato de caso

Facial injuries vary in their clinical characteristics and complexity, deserves an appropriate approach for each case, considering that the failures may result in aesthetic and functional changes that can be harmful both functionally and psychologically. Aspects such as exposure time of the injury, anesthesia, suture materials and tetanus prophylaxis are important factors. The objective is to present a case of extensive facial injuries in an automobile accident patient.

Parâmetros assistenciais em saúde bucal: comparação entre duas programações do atendimento clínico no serviço público

Objective: To compare two forms of scheduling clinical dental care for the oral health teams (OHT) included in the strategy of family health, regarding productive aspects of assistance. Methods: Two OHT worked concurrently, using two methods of clinical care: the parameter recommended by the Ministry of Health Ordinance No. 1101, 2002, which establishes 03 dental visits per hour (c/h) per team, and a Testing model, with 02 c/h, being each method applied for a period of 615 hours. The quantitative data was collected in OHTs’ daily production spreadsheets, covering the following items: the number of dental visits (initial, for maintenance and for emergency procedures), procedures performed, consumption of material and sterilization cycles. Data was compared and statistically analyzed through the BioStat 5.0 by applying the paired t-test (p <0.05). Results: Under the Ministerial method and the Testing model, were performed, respectively, 288 and 365 first dental visits, 921 and 686 return dental visits, 167 and 172 emergency dental attendances, with 469 and 110 fouls, 212 and 327 treatments were finished and 2501 and 3046 dental procedures were realized. Among eleven analyzed consumables, five were consumed in smaller quantities in the Testing model: gloves (9%), anesthesia (38%), anesthetic needle (34%), suture material (24%) and aspirators (11%), while the six remaining items presented similar consumption rates between the two models. Conclusions: The testing model revealed to be more productive and economical.

Particularities in the technique of calvaria graft

Calvaria grafts provide good bone quantity for the reconstruction of the atrophic maxilla, and have lower morbidity and resorption rates when compared to iliac crest. The aim of this paper is to present the technique for obtaining a graft of the skull. Initially, the depth of the osteotomy is determined by a manually conducted bur, which establishes the limits of the structures of the skull (outer table, diploe and inner table), making the removal of bone blocks easier and safer. Thus, osteotomies of the blocks are made with greater security, avoiding the complications inherent to surgical technique. The case that will be presented it is from a male patient of 65 years who refused to submit to the iliac crest graft, opting for the calvaria, despite being bald, that is a contraindication for this treatment modality. A delicate suture associated with placement of titanium mesh to maintain the conformation of the patient's skull in the region of the bone defect, created after removal of the graft, provided a good cosmetic result at the donor site. The use of titanium mesh for re-anatomization of bone defects created in the grafts is well indicated for bald patients.

Osteologia craniana e aspectos evolutivos de Mycteria (Aves: Ciconiidae)

The genus Mycteria (Ciconiidae) is composed of species with controversial phylogenetic hypotheses of relationships. This study sought to describe the cranial osteology of the four species included in the genus Mycteria, comparing with representative species from other genera of the family. The monophyly of Mycteria coud be hypothesized based on the following cranial characters: 1) medial process of the mandible medially oriented and 2) pseudo temporal tubercle developed when compared to other species Ciconiidae. Mycteria ibis and M. leucocephala are sister groups supported by: 1) deep temporal fossa, 2) reduced “T” tubercle and 3) expansion of the caudal fossa coanalis relative to other species of Ciconiidae. Among the species studied, the most basal was M. cinerea and the taxon formed by M. ibis and M. leucocephala is sister group of M. americana, sustained by the presence of total fusion of lacrimal and frontal bones, whereas in remaining species of Ciconiidae the suture between these bones is visible.

Acute phase response following ovariohysterectomy in female dogs

The concentrations of acute phase proteins are correlated with the severity of the surgical trauma, being elevated when severe tissue injury is produced. The aim of this study was to evaluate the leukogram and the acute phase proteins concentrations in healthy female dogs submitted to minimally invasive ovariohysterectomy, with the use of nylon cable ties (G1), and conventional (laparotomy) ovariohysterectomy, with the use of nylon suture (G2), as methods to ligate the ovarian pedicles and uterine body, respectively. Blood samples from 30 adult healthy female dogs (15 for each group) were obtained before surgery, and at 24 and 48 h and 7 days after surgery. Serum protein fractions were determined by means of sodium dodecyl sulfate polyacrylamide gel electrophoresis. Neutrophilia was observed 24 h after both surgical procedures but did not differ (P ≥ 0.05) between the groups. In G1, the estimated concentration of ceruloplasmin increased (P ≤ 0.05) 48 h after the surgical procedure. The estimated ceruloplasmin concentration was significantly higher in G1 (P ≤ 0.05) when compared to G2 48 h postoperatively, and the estimated haptoglobin concentration was also significantly greater in G1 (P ≤ 0.05) than in G2 from 24 h to 7 days after surgery. Through the ceruloplasmin and haptoglobin estimated concentrations, we conclude that the minimally invasive ovariohysterectomy caused a more intense inflammatory response, which was not reflected in the white blood cell count.
