Rehabilitación de trauma facial ocasionado por fuegos artificiales utilizando triamcinolona / Aesthetic and functional rehabilitation using triamcinolone on patient suffered by facial firework injury

Introduction: Facial injuries are a common occurrence at the emergency room. Treatment for this type of trauma is complex in terms of re-establishing good oral and facial function, plus aesthetics. Objective: This paper aims to report a clinical case of aesthetic and functional rehabilitation using triamcinolone in a patient affected on the face by a fireworks explosion. Case report: A 26-year-old man was admitted to the oral and maxillofacial surgery service of the Sergipe Urgency Hospital presenting trauma after the explosion of a "Firework rocket" in his face. The patient had extensive soft tissue injury in gingival mucosa, right labial commissure, and tongue. There was also inferior incisive avulsion and dentoalveolar fracture. His clinical and tomographic evaluation presented comminuted mandibular fracture. After eighteen days he was discharged and sent to the dentistry service of the Federal University of Sergipe for aesthetic and functional rehabilitation of his facial damages. Two months later, the patient attended a University dental service to begin aesthetic and postoperative functional rehabilitation. First, the necrotic bone was removed, following intralesional infiltration of hexacetonide triamcinolone 20mg/mL into the scar of the labial region and the commissure of the lips was performed. Each application was performed after twenty days of interval. Later, lingual frenectomy and glossosplasty were done for improving his lingual mobility and then hexacetonide triamcinolone 20mg/mL infiltrations were also done in the tongue base in the following sessions. Conclusions: After five infiltrations, it was observed an improvement in the scar appearance and texture, which also had a lower contracture, as well as a lingual motricity improvement(AU)

Introducción: Las lesiones faciales son frecuentes en el servicio de emergencia. El tratamiento para este tipo de trauma es complejo en términos de restablecer una buena función bucal y facial, además de la estética. Objetivo: Reportar un caso clínico de rehabilitación estética y funcional a través del uso de hexacetónido de triamcinolona en un paciente afectado por una explosión de fuegos artificiales en su rostro. Caso clínico: Hombre de 26 años ingresado en el servicio de cirugía oral y maxilofacial del Hospital de Urgencia de Sergipe por presentar un traumatismo después de la explosión contra su rostro de un cohete de fuegos artificiales. El paciente tenía una lesión extensa de partes blandas en la mucosa gingival, comisura labial derecha y lengua. También hubo avulsión incisiva inferior y fractura dentoalveolar. A través de la evaluación clínica y de tomografía, fue posible observar fragmentación múltiple ósea en el sitio de la fractura, compatible con fractura mandibular conminuta. Después de dieciocho días fue dado de alta y enviado al servicio de odontología de la Universidad Federal de Sergipe para la rehabilitación estética y funcional de sus daños faciales. Dos meses después, el paciente asistió al servicio dental de la universidad para comenzar la rehabilitación funcional estética y posoperatoria. Primero, se retiró el hueso necrótico, luego se realizó la infiltración intralesional de hexacetónido de triamcinolona 20 mg/mL en la cicatriz de la región labial y se realizó la comisura de los labios; con un intervalo de 20 días entre cada aplicación. Posteriormente, se realizaron frenectomía lingual y glososplastia, para mejorar su movilidad lingual, y luego se realizaron infiltraciones de 20 mg/mL de hexacetónido de triamcinolona en la base de la lengua en las sesiones siguientes. Comentarios principales: Después de cinco infiltraciones se observó una mejora en el aspecto y la textura de la cicatriz, que también tenía una contractura más baja, así como una mejora de la motricidad lingual(AU)

Palatal needle-free anesthesia for upper molars extraction. A randomized clinical trial.

BACKGROUND: The aim of this study was to compare the ability of liposomal and non-liposomal lidocaine and prilocaine in hydrogel formulations to promote topical anesthesia in palatal mucosa during upper molar extractions. METHODS: In this randomized, cross over, triple-blinded clinical trial, a liposomal and a non-liposomal formulation of the eutectic mixture of local anesthetics, 2.5% lidocaine and 2.5% prilocaine, were used to promote palatal anesthesia without the local anesthetic infiltration during bilateral upper molars extractions. RESULTS: From the total of 40 patients included in this study, the non-liposomal eutectic lidocaine-prilocaine formulation failed in 40% of cases, unlike the liposomal formulation, which was effective for all patients (Fisher's exact test, p < 0.0001). Furthermore, the liposomal formulation (26.75 ± 7,47 min) induced longer anesthesia duration (t-test, p < 0.0001) than the non-liposomal formulation (16.78 ± 4.75 min). No mucosal ulceration or discomfort was reported for both formulations. CONCLUSION: The liposomal formulation was able to induce adequate anesthesia in palatal mucosa during dental extraction, avoiding the local anesthetic infiltration. For the first time, a topical formulation allowed upper molars surgical removal without injection of any local anesthetic agent into palatal mucosa in adults.

Comparison of two vasoconstrictors on glycemic levels in diabetic patients.

OBJECTIVES: The aim of this study was to evaluate glycemic levels in diabetic patients before, during, and after extractions using 2% lidocaine with 1:100,000 epinephrine (Lido/Epi) and 3% prilocaine with 0.03 IU/mL felypressin (Prilo/Fely). MATERIALS AND METHODS: A double-blind, randomized clinical trial was conducted to evaluate changes in body parameters and glycemic levels in diabetic patients undergoing two anesthetic protocols during dental extractions. During surgery, we evaluated blood pressure (BP), heart rate (HR), saturation (SpO2), and capillary glycemic levels (Gly). These parameters were measured at the following surgical moments: basal, 30 min after medication, incision, tooth removal, suture, and 30 and 60 min after anesthesia. RESULTS: Data analysis showed no differences between the groups considering age, weight, and time spent in surgery. Increased systolic BP and decreased diastolic BP were observed in the lido/epi group. No difference was observed in the prilo/fely group among the surgical moments or between the groups regarding BP. No difference was observed in HR and SpO2 between the groups at any surgical moment. However, differences were found when compared the differences in glycemic and basal levels in both groups with greater decreases in blood glucose values for the lido/epi group. In anxiety level evaluation, there was no difference between the different surgical moments. CONCLUSION: Thus, both lido/epi and prilo/fely (maximum 3.6 mL) can be safely used in controlled diabetic patients CLINICAL RELEVANCE: The use of lidocaine associated with epinephrine did not increase glycemic levels but leads to decrease over time when associated with an anxiety reduction protocol, offering some advantage over prilocaine plus felypressin for diabetic patients.

Fratura cominutiva de mandíbula por fogos de artifício: relato de caso / Comminuted mandible fracture by firework: a case report

As fraturas mandibulares são comuns na rotina dos serviços de Cirurgia e Traumatologia Buco-maxilo-facial. Embora sejam raras, as fraturas ocasionadas por fogos de artifício merecem atenção devido ao poder de destruição. O presente trabalho tem como objetivo relatar um caso de fratura mandibular cominutiva, com perda de substância dos tecidos duros e moles da face e cavidade oral. Nesse caso, foi preciso celeridade ao tratamento cirúrgico de urgência, para assegurar as vias aéreas do paciente e, em seguida, reconstruir as áreas destruídas, tendo todo o cuidado em relação ao acompanhamento do caso devido aos riscos de infecção e possíveis sequelas...

The mandible fractures are common in routine of Oral & Maxillofacial Surgery services. However, the ones occasioned by fireworks are rare. Nevertheless, they deserve attention because of the their destruction power. The present study aims to report a case of comminuted mandible fracture, with loss of substance from hard and soft tissues from the face and mouth. In this case, emergency surgery was urgently needed, to ensure the airways and then to rebuild the destroyed areas, paying attention to the follow-up of the case because of the high risk of infection and possible complications...
