The outbreak caused by the SARS-CoV-2 virus is currently very active in Spain. Many infected people still require to be hospitalized. Around 10-15 % of hospitalized patients require intensive care, where they are intubated for a prolonged period, needing tracheotomies some weeks after the intubation. We will be conducting an observational study of the tracheotomies performed by our oral and maxillofacial Department to COVID-19 patients on intensive care units between March 17th and April 17th, 2020. This study will be analyzing the patients’ epidemiological and clinical aspects, surgical technique employed, surgical time, type of cannula used, postoperative complications and the patients’ clinical monitoring. A total of 22 patients underwent open elective tracheotomy. There were twenty-two males and three females aged between 40 and 77 (mean: 64,9 years-old). In all cases tracheotomy was carried out due to pulmonary process caused by COVID-19 bilateral pneumonia. Two patients presented pneumothorax in the immediate postoperatory care as a complication, one perished during the procedure and another did so after arriving to the Intensive Care Unit after the tracheotomy surgery. Even though tracheotomy is a ruled surgical technique, the special characteristics of COVID-19 patients make of this procedure a critical situation, mainly due to lung instability and quick desaturation of the patients. This requires the surgery to be carried out by experienced physicians in order to reduce operative time and to be able to react to any eventualities that may arise.

Aims: A retrospective study was conducted in the Department of Oral and Maxillofacial Surgery Dr. Atilio Perdomo; Ángel Larralde Hospital, CaraboboVenezuela, which describes the procedure and protocol of the postoperative period of patients operated on multiple occasions for the closure of palatal fistulas. Material and methods: A total of 20 patients treated for palatal fistulas were included in this study, in the period between 2014-2018. Patients with presence of sequelae of palatal fistulas, large fistulas with inadequate local scars, presence of oronasal communication and hypernasal resonance were considered. Patients were evaluated during the first 24 hours, 21 days and 6 months. Results: A total of 20 patients (12 men and 8 women) with palatal fistulas were treated with tongue flap, aged between 25 and 40 years. In the postoperative period, patients reported 58% of cases, mild pain. The most frequent clinical signs during the postoperative period were presented in 60% of the patients, showing headache, passive bleeding, severe pain. No significant changes in lingual motility. Acoustic analysis of the 6month late postoperative control voice, presented favorable changes in the intonation line, showing its continuity. All remaining cases showed satisfactory cure, and donor site morbidity was minimal. Conclusions: The tongue flaps are an excellent alternative for closing large or recurrent palatal fistulas, due to their versatility and excellent vascularity of the area. However, the design and the delicate manipulation of the flap are also decisive.

Introduction: Crying in newborns and infants is a functional expression of biological interest. Through, acoustic analysis of crying, results of a primary palatoplasty can be evaluated in patients with cleft palate before development of speech, is objective, non-invasive, quick and simple tool for vocal exploration. The objective is to determine Fundamental Frequency (F0) of spontaneous crying in patients with pre and postoperative cleft palate, and compare with healthy control group through PRAAT software, in period between 2017 and 2019. Materials and methods: A sample of 16 patients from 18 to 30 months of age with cleft palate was obtained. Recordings were made of spontaneous pre and postoperative crying, and healthy control group; later were digitally recorded, and analyzed through PRAAT Software. Results: 56.2 % were female and 43.7 % were male, witn average age of 25.8 months. Primary palatoplasty was performed using Veau Wadrill technique and Furlow technique. F0 of crying was Pitch average value 349.125 Hz preoperative and Pitch average postoperative control 369.775 Hz. More acute crying emissions were observed in postoperative period (p < 0.000), presenting similar values with control group (p < 0.000). Conclusion: Fundamental frequency (F0) was determined in patients with cleft palate, they presented a significant increase of 15,5 % in postoperative controls of primary palatoplasty, similar to healthy control group.

Introduction: Restoration of normal orbital volume and globe position following traumatic injury is often difficult. Intraoperative navigation has emerged as a tool to allow the visualization of the implant position intraoperatively, by means of the planification in the preoperative computed-tomographic scan (CT scan). Objectives: The aim of this study was to compare the postoperative changes in orbital volume between two groups of study: one group that underwent surgical intervention before the implementation of intraoperative navigation (control group), and other group of patients which had undergone surgery with the aid of a navigation system (Software iPlan CMF version 3.0.5, Brainlab®, Feldkirchen, Germany) (navigation group). Another endpoint of our study was to determine it the presurgical planification and intraoperative navigation aided to position the implant. For that purpose, we determined the implant position with respect to the orbital floor and medial orbital wall and compared it between both groups of study. As secondary endpoints, we compared the rate of postoperative outcomes and reintervention rate between both groups. Materials and methods: A retrospective cohort study was designed. We selected a total of 35 consecutive orbital operations for unilateral orbital fractures performed between 2015 and 2018 at the Department of Oral and Maxillofacial Surgery in La Paz Hospital (Madrid), Spain. We collected information regarding: demographic data, cause of the fracture, time elapsed between diagnosis and surgical treatment, symptoms at diagnosis (diplopia, globe projection, ocular motility impairment), radiological findings (affected wall, muscular entrapment, herniation of the periorbital structures), and outcomes after surgical treatment (diplopia, globe position, ocular motility impairment, reintervention). By means of the iPlan CMF software, the orbital volume was determined in the preoperativeand postoperative CT scan. The plate position was determined by measuring the distance between the plate and the orbital rim, the distance between the plate and the residual posterior intact bony ledge and the distance between the plate and the medial orbital wall. Measurements were performed automatically in the three planes of space, although we used the sagital plane to measure the distance between the plate and the orbital rim and between the plate and the residual posterior intact bony ledge. To measure the distance between the plate and the medial orbital wall we used the axial plane. Results: After surgery, we observed that abnormal globe position was significatively less frequent in the navigation group than in the control group (p = 0.029). The reoperation rate was 11 % in the navigation group and 35% in the control group (p = 0.071). Mean orbital volume of the unaffected orbit was 29.32 ± 2.64 cm3 in the navigation group and 28.64 ± 2.68 cm3 in the control group. Mean orbital volume of the affected orbit was 34.19 ± 3.67 cm3 in t

ABSTRACT Aim: In biomaterials and tissue engineering studies, dental pulp cells are used to regenerate or replace deficiencies of bone tissue in the oral cavity. To evaluate its clinical potential, cell culture models are employed, in which different extraction methods of the dental pulp are applied. Mainly, the tooth is broken by fracture mechanics and the cutting method to obtain the dental pulp. However, it is not clear yet which method is the most convenient. Therefore, the purpose of this study was to compare the effect of two methods of fracture mechanical and cutting methods on the dental pulp cell viability. Methodology: Dental pulp tissue was removed of fully developed and healthy teeth of 32 patients between 18 to 40 years, through two techniques: the methods of fracture mechanics (group 1) and cutting (group 2). To determine the cell viability, trypan blue dye was used. The cells were counted in the microscope, blue stained cells (dead) and birefringent (living). Results: Using the mechanical fracture method, 87.72 % of cell viability was obtained. While with the cutting method was achieved a lower viability 83.59 %. There was a significant difference (p = 0.006) when analyzing the data (n = 16 per group) under t-Student test. Conclusions: The use of mechanical fracture method for the extraction of the dental pulp tissue allows to obtain higher percentages of cell viability compared to cutting method.

There was a significant difference (p = 0.006) when analyzing the data (n = 16 per group) under t-Student test. \u0000 \u0000Conclusions: \u0000The use of mechanical fracture method for the extraction of the dental pulp tissue allows to obtain higher percentages of cell viability compared to cutting method.","PeriodicalId":35298,"journal":{"name":"Revista Espanola de Cirugia Oral y Maxilofacial","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68143885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
