Extraoral surgical removal of an ectopic impacted third molar of the mandible. Report of a case

2020

Intraoral approach for the removal of impacted third molars represents a common surgical procedure for the specialized clinician. However, in some cases such as ectopic third molars, extraoral surgical removal seems to be inevitable. We present a step by step case of a 56 year old woman with an ectopic third molar of the lower jaw along with a cystic lesion, which were surgically removed by a submandibular approach. Postoperative clinical course was uneventful and there were no signs of facial nerve paresis. In such cases, appropriate preoperative planning must be made based on careful study of radiographic imaging and clinical examination. The more conservative technique that would minimiz…

Efficacy of fentanyl transdermal patch in pain control after lower third molar surgery: A preliminary study

2015

Background Surgical removal of impacted lower third molars is a common oral surgical procedure, generally followed by moderate to severe postoperative pain. Transdermal drug delivery as a concept offers interesting possibilities for postoperative pain control. The aim of this study was to evaluate the efficacy of transdermal system with fentanyl in relieving pain following impacted lower third molar surgery. Material and Methods Seventeen patients with bilateral impacted lower third molars were included in this preliminary study. For postoperative pain control, patients randomly received a fentanyl patch plus placebo tablet after the first operation and regular (placebo) patch and an analge…

Infectious postoperative complications in oral surgery. An observational study

2019

Background The main objective of this investigation was to determine the incidence of infectious postoperative complications in oral surgery. Material and methods A observational and descriptive study was developed, with the use of prospective registry of the patients admitted for oral surgery at the San Borja Arriaran Hospital Complex during twelve months observation period (April 2017 to March 2018). Results The sample consisted of 532 patients undergoing surgical procedures of oral surgery and 19 cases of infectious postoperative complications. The incidence of complications reached 3,57% and it was observed predominantly in exodontic type interventions. The most commonly observed compli…

Comparison of the analgesic efficacy of oral ketorolac versus intramuscular tramadol after third molar surgery: A parallel, double-blind, randomized,…

2015

Background Preemptive analgesia is considered an alternative for treating the postsurgical pain of third molar removal. The aim of this study was to evaluate the preemptive analgesic efficacy of oral ketorolac versus intramuscular tramadol after a mandibular third molar surgery. Material and Methods A parallel, double-blind, randomized, placebo-controlled clinical trial was carried out. Thirty patients were randomized into two treatment groups using a series of random numbers: Group A, oral ketorolac 10 mg plus intramuscular placebo (1 mL saline solution); or Group B, oral placebo (similar tablet to oral ketorolac) plus intramuscular tramadol 50 mg diluted in 1 mL saline solution. These tre…

Effect of pre-operatory low-level laser therapy on pain, swelling, and trismus associated with third-molar surgery

2017

Background The extraction of impacted third molars is commonly associated to pain, edema, trismus, limited jaw opening and movements. The aim of this retrospective study is to verify if pre-surgical low-level laser therapy (LLLT) associated with the extraction of impacted lower third molars could add benefits to the postoperative symptoms respect LLLT performed only after surgery. Material and Methods Data from 45 patients subjected to a surgical extraction of lower third molars were pooled and divided into three groups. Patients that received only routine management were inserted in the control group. Group 1, were patients that received LLLT immediately after surgery and at 24 hours. In g…

Influence of surgical ultrasound used in the detachment of flaps, osteotomy and odontosection in lower third molar surgeries. A prospective, randomiz…

No. of bitstreams: 0 Previous issue date: 2020-07-01 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Background: As third molar surgery is the most commonly procedure performed in Dentistry and has been accompanied by serious postoperative disorders such as pain edema and trismus, the study aimed to evaluate if ultrasound device would be able to reduce such postoperative features. The aim of this study was to assess the effects of soft tissue flap elevation, osteotomy and odontosection using piezosurgery versus conventional technique in mandibular third molar extractions. Material and Methods: Twenty patients with impacte…

Graft-versus-host disease (GvHD) is a key contributor to the morbidity and mortality after allogeneic hematopoetic stem cell transplantation (HSCT). Regulatory Foxp3(+) CD4(+) T cells (Treg) suppress conventional T cell activation and can control GvHD. In our previous work, we demonstrate that a basic mechanism of Treg mediated suppression occurs by the transfer of cyclic adenosine monophosphate (cAMP) to responder cells. Whether this mechanism is relevant for Treg mediated suppression of GvHD is currently unknown. To address this question, bone marrow and T cells from C57BL/6 mice were transferred into lethally irradiated BALB/c recipients, and the course of GvHD and survival were monitore…

Multimedia application to support distance learning and other social interactions in real-time

2000

Supporting social interactions, in distance learning situations for example, with modern technology is very difficult. Generally Internet, networked PC, document handling and communication services and applications are not designed from a multiple user perspective but to support a one-person-one-device (or tool) interaction. This approach creates problems for supporting awareness of, and communication with other people while simultaneously working on documents. Such simultaneous activities have been identified as essential by CSCW and CHI studies, where users are reported to move promiscuously between media and devices, and combine applications and media intuitively, while maintaining aware…

Critical approach to 3D virtual realities for group work

2002

Collaborative virtual environments (CVEs) have been studied extensively during the past few years. In this paper, the concept of virtual reality (VR), and its value for group work are critically examined. To ground the discussions, experiences from a virtual reality project, from 3D chats, and from present CVE applications are analysed in the light of human communication. It is argued that the value of virtual reality is often overemphasised and overrated in the group work context, especially when conce rning desktop virtual realities and generic groupwork without an explicitly defined task or purpose. The main problem with VR is its self-centricity and inadequate support for shared real-li…

Perioperative Management of Pheochromocytoma: From a Dogmatic to a Tailored Approach

2021

Background: Perioperative management of pheochromocytoma (PCC) remains under debate. Methods: A bicentric retrospective study was conducted, including all patients who underwent laparoscopic adrenalectomy for PCC from 2000 to 2017. Patients were divided into two groups: Group 1 treated with alpha-blockade, and Group 2, without alfa-blockers. The primary end point was the major complication rate. The secondary end points were: the need for advanced intra-operative hemostasis, the admission to the intensive care unit (ICU), the length of stay (LOS), systolic (SBP), and diastolic blood pressure (DBP). Univariate and multivariate analysis was conducted. A p-value &lt
