Is the injection of tramadol effective at control of pain after impacted mandibular third molar extractions? A systematic review and meta-analysis

Background: Third molar extraction is among the most common surgical procedures performed by oral-maxillofacial surgeons. Postoperative pain, swelling and trismus are common, especially in wisdom teeth, due to trauma to local tissues and the duration of the surgical procedure, among other factors. Material and methods: This systematic review was conducted in accordance with the 'Preferred Reporting Items for Systematic Reviews and Meta-Analyses' in order to answer the focused question: 'Is the local submucosal injection of tramadol effective at the control of postoperative pain in patients submitted to impacted mandibular third molar extractions?'. We analyzed papers published until March 30, 2021 in the MEDLINE|PubMed, Web of Science and Cochrane Library databases. Gray literature was also consulted. Standard pairwise meta-analyses of direct comparisons were performed using a fixed-effect model; I2 ≥ 50 % or ≥ 75 % indicated moderate or high heterogeneity, respectively. Risk of bias was assessed by Cochrane Collaboration's tool. Results: In total, 172 participants (98 males and 74 females, aged 18 or over) from three randomized placebo-controlled trials were considered for analysis. The submucosal injection of 2 ml of tramadol adjacent to the impacted mandibular third molar was effective in controlling pain up to 6-hours after surgery, in increasing the onset of consumption of rescue analgesic and in reducing the total number of rescue analgesics used. Conclusions: The submucosal injection of tramadol can be considered a safe and effective procedure for pain control after impacted mandibular third molar extractions. (AU)

Surgical Management of Gunshot Injury to the Temporomandibular Joint.

One of the indications of the surgical approach of the temporomandibular joint is the presence of foreign body in its interior. However, joint handling offers risks, especially bleeding. In these cases, angiography and embolization of the arteries involved with the projectile play an important role in the prevention of complications. In this report, the authors describe a case of a 23-year-old male victim of firearm attack with comminuted fracture of the right mandibular condyle. The patient underwent angiography and prophylactic embolization of the arteries adjacent to the foreign body. A surgical procedure was performed to remove the projectile and bone fragments with the aid of the X-ray image intensifier, which resulted in the restoration of mandibular function, absence of joint pain, and satisfactory dental occlusion. This case shows the importance of auxiliary imaging methods for performing a safe surgical procedure for removal of ballistic and bony fragments from the interior of the temporomandibular joint.

Manejo de fratura bilateral de mandíbula através de fixação interna rígida pela técnica de Champy ­ relato de caso / Management of bilateral mandibular fracture through rigid internal fixing by Champy technique ­ case report

As fraturas de mandíbula são as mais comuns no campo da Cirurgia e Traumatologia Bucomaxilofacial. Acometem cerca de 42,5% dentre os traumas faciais. O método a ser escolhido para o tratamento depende de diversos fatores, como o deslocamento e a cominuição dos fragmentos ósseos, a presença de má oclusão, a ação muscular local, a idade do paciente e a habilidade do cirurgião. Este trabalho tem por objetivo relatar um caso de fratura bilateral de mandíbula em corpo esquerdo e ângulo direito, tratado através de fixação interna rígida e técnica de Champy. Esta abordagem mostrou-se eficaz e segura neste tratamento, além de evitar cicatrizes antiestéticas e lesões às estruturas adjacentes. Um resultado pós-operatório de 3 meses é apresentado (AU).

Mandibular fractures are the most common in the field of Buccomaxillofacial Surgery and Traumatology. The prevalence rate is about 42.5% of facial traumas. The method of choice for the treatment depends on several factors, such as displacement and comminution of the bone fragments, presence of malocclusion, local muscular action, the age of the patient and the surgeon's skill. This paper aims to report a case of bilateral mandibular fracture in the left body and right angle treated through rigid internal fixation and the Champy technique. This approach proved to be effective and safe in this treatment, besides avoiding unsightly scars and lesions on adjacent structures. A 3-month postoperative result is presented (AU).
