A cervicofacial emphysema was found when the physical exam was carried out. Computerized axial tomography was indicated, which showed fracture of the medial and lateral walls of the left maxillary sinus. It was decided to use the conservative technique for air extraction by means of the needles placement. The patient had a favorable clinical course and he didn't have relapses.

Neumomediastino espontáneo en pacientes COVID-19. Serie de casos / Spontaneous pneumomediastinum in COVID-19 patients. Case series

Resumen El neumomediastino espontáneo es la presencia de aire libre en el mediastino sin el antecedente de alguna causa como trauma de tórax. Es una condición benigna autolimitada que se trata en forma conservadora. El diagnóstico clínico se basa en dos síntomas: dolor torácico y disnea; y en un signo en particular: enfisema subcutáneo. Ha sido reportado en pacientes con influenza A (H1N1) y síndrome respiratorio agudo grave; sin embargo, ha sido raramente observado en pacientes con COVID-19. En este trabajo describimos seis pacientes del sexo masculino con COVID-19, con edades entre 27 y 82 años, que presentaron neumomediastino espontáneo y enfisema subcutáneo; ambos se reabsorbieron totalmente con manejo conservador.

Abstract Spontaneous pneumomediastinum is defined as the presence of free air within the mediastinum without an apparent cause such as chest trauma. It is a benign, self-limiting condition that is conservatively treated. Clinical diagnosis is based on two symptoms: chest pain and dyspnea; and on a particular sign: subcutaneous emphysema. It has been reported in patients with influenza A (H1N1) and severe acute respiratory syndrome; however, it has been rarely observed in COVID-19 patients. In this work, we describe six male patients with COVID-19, aged between 27 and 82 years, who presented with spontaneous pneumomediastinum and subcutaneous emphysema; both conditions were completely resorbed with conservative management.

Spontaneous pneumomediastinum incidence and clinical features in non-intubated patients with COVID-19

OBJECTIVES: To evaluate the presentation characteristics and disease course of seven patients with COVID-19 who spontaneously developed pneumomediastinum without a history of mechanical ventilation. METHODS: A total of seven non-intubated patients with COVID-19, of age ranging from 18-67 years, who developed spontaneous pneumomediastinum between 01 April and 01 October 2020 were included in the study. Patients' demographic data, clinical variables, and laboratory values were examined. Spontaneous pneumomediastinum was evaluated using posteroanterior chest radiography and thorax computed tomography. RESULTS: During the research period, 38,492 patients reported to the emergency department of our hospital with COVID-19 symptoms. Of these, spontaneous pneumomediastinum was detected in seven patients who had no previous history of intubation. Chronic obstructive pulmonary disease (2/7) and asthma bronchiale (2/7) were determined as the most common causes of comorbidity. CONCLUSIONS: In our study, the frequency of spontaneous pneumomediastinum developing without pneumothorax was found to be high in non-intubated patients. Whether this is related to the nature of the disease or it is a result of the increase in cases diagnosed incidentally owing to the increasing use of low-dose computed tomography should be explored in further studies.

Mediastinitis necrotizante descendente de origen dental: revisión de la literatura y presentación de un caso / Descending necrotizing mediastinitis of dental origin: a case study and review of the literature

La mediastinitis se define como una inflamación aguda severa de los tejidos conectivos ubicados en la cavidad torácica media, en la que 20% de los casos puede implicar una infección difusa y polimicrobiana del mediastino denominada mediastinitis necrotizante descendente (MND), secundaria a la propagación de una infección grave desde los tejidos bucofaríngeos o cervicales tales como infecciones odontogénicas (de 36 a 47%), faríngeas (de 33 a 45%), cervicales (15%) y otras infecciones de cabeza y cuello (5%). Clínicamente, los pacientes presentan aumento de volumen, temblores, trismus, odinofagia con disnea, disfagia, hipotensión, dolor de cuerpo y del ángulo de la mandíbula. Puede observarse signo de Hamman (crepitación mediastinal con el latido cardiaco) y enfisema subcutáneo. El manejo quirúrgico de las infecciones odontogénicas, sin importar su severidad, consta de dos principios: eliminar el foco etiológico y el vaciamiento quirúrgico de los espacios anatómicos comprometidos con la instalación de un drenaje adecuado. Se presenta el caso de un masculino de 60 años con diagnóstico de mediastinitis necrotizante descendente de origen dental (AU)

Mediastinitis is defined as a severe acute inflammation of the connective tissues affected in the middle thoracic cavity, in which 20% of cases may involve a diffuse and polymicrobial infection of the mediastinum, descending necrotizing mediastinitis (MND), secondary to the spread of a serious infection from the oropharyngeal or cervical tissues, stories such as odontogenic infections (36 to 47%), pharyngeal (33 to 45%), cervical (15%) and other head and neck infections (5%). Clinically, patients present with increased volume, tremors, trismus, odynophagia with dyspnea, dysphagia, hypotension, pain in the body and in the angle of the jaw. Hamman sign (mediastinal crepitus with heartbeat) and subcutaneous emphysema may be observed. The surgical management of odontogenic infections, regardless of their severity, consists of two principles: eliminate the etiological focus and the surgical emptying of the anatomical spaces compromised with the installation of adequate drainage. We present the case of a 60-year-old man diagnosed with descending necrotizing (AU)

Neumomediastino espontáneo idiopático. Primer caso pediátrico en Colombia / Idiopathic spontaneous pneumomediastinum. First colombian pediatric case

Resumen El neumomediastino espontáneo idiopático es la presencia de aire en el mediastino, sin ninguna causa aparente, siendo descrito en 1939 por el Dr. Hamman. Se atribuye a una fuga dinámica de aire desde los alvéolos a través del intersticio de personas jóvenes (efecto Macklin). La clínica no es específica, pero el dolor torácico agudo retroesternal y la tos, son los síntomas más orientativos; los signos más específicos son los crépitos precordiales (signo de Hamman) y el enfisema subcutáneo. La radiografía de tórax es suficiente para el diagnóstico, aunque otras técnicas de imagen sirven para evaluar causas secundarias. El tratamiento es reposo, analgésicos y, opcionalmente, oxígeno suplementario. Se presenta el caso de un niño en edad escolar con neumomediastino espontáneo sin ningún desencadenante identificable, siendo el primer caso pediátrico colombiano reportado de esta variante. MÉD.UIS.2019;32(2):47-52

Abstract Idiopathic spontaneous pneumomediastinum is the presence of air in the mediastinum, without any apparent cause, it was described in 1939 by Dr. Hamman. It is attributed to a dynamic escape of air from the alveoli through the pulmonary interstice of young people (Macklin effect). The clinical symptoms are not specific, but acute retrosternal chest pain and cough are the most indicative symptoms; the most specific signs are precordial crepitus (Hamman's sign) and subcutaneous emphysema. The chest X-ray is enough for the diagnosis; however, other imaging techniques are used to evaluate secondary causes. The treatment is rest, analgesics and, optionally, supplemental oxygen. There is presented the case of a school-age child with spontaneous pneumomediastinum without any identifiable trigger, being the first reported Colombian pediatric case of this variant.

INTRODUCCIÓN: El neumomediastino es la presencia de aire en el mediastino, tiene incidencia variable que oscila entre 1/80 000 y 1/42 000 a nivel mundial, genera una diversidad de características clínicas, puede ser secundario a entidades torácicas o extra torácicas; dentro de las causas extratorácicas, podemos asociarlo a procedimientos dentales siendo de vital importancia considerar la posibilidad y la asociación a dichos procedimientos para su diagnóstico y tratamiento adecuado. CASO CLÍNICO: Paciente de sexo femenino de 23 años, que 24 horas previas a su ingreso, se realizó procedimiento dental tipo exodoncia del tercer molar inferior izquierdo, en el que se usó instrumental manual y neumático, que debió ser suspendido; la paciente presentó dolor intenso más dificultad respiratoria, posterior a ello dolor torácico opresivo, mandibular y en cuello de lado izquierdo, acompañado de enfisema subcutáneo en hemicara izquierda, cuello bilateralmente y subclavicular izquierdo. EVOLUCIÓN: Paciente es ingresada con diagnóstico de neumomediastino secundario a procedimiento dental para tratamiento antibiótico de amplio espectro y vigilancia, durante su hospitalización por tres días permanece estable, afebril con mejoría clínica general. CONCLUSIÓN: El neumomediastino es una complicación poco frecuente tras intervenciones odontológicas, se debe sospechar por el uso de instrumental neumático que disecan los tejidos blandos faciales, del cuello y tórax; la paciente tuvo una evolución favorable en base al diagnóstico y tratamient

BACKGROUND: Neumomediastinum is defined as the presence of air in the mediastinum, It has variable incidence that oscillates between 1/80000 and 1/420000, generates a diversity of clinical characteristics. It can be secondary to thoracic or extra thoracic entities, within extrathoracic causes; it can be associated with dental procedures, being of vital importance consider the possibility and the association to this procedure to get to an adequate diagnosis and treatment. CASE REPORT: A 23-year-old female patient who, 24 hours prior to admission, underwent a dental procedure such as a third-molar left third molar extraction, in which manual instruments and pneumatics dental lathe were used, which had to be suspended; the patient presented severe pain plus respiratory difficulty, after that she presented oppressive chest pain, mandibular and left side neck, accompanied by subcutaneous emphysema in the left side of the face, neck bilaterally and left subclavicular EVOLUTION: The patient was hospitalize with a diagnosis of neumomediastinum secondary to dental procedure to receive treatment with broad spectrum antibiotic and surveillance, during her hospitalization for three days she remains stable, afebrile with general clinical improvement. CONCLUSIONS: The neumomediastinum is a rare complication after odontological interventions. It should be suspected when pneumatic instrument lathe are used that dissect facial, neck and thorax soft tissues; the patient had a favorable evolution based on the diagnosis and early treatment proposed by the doctors according to the patients symptoms.

Avulsión de bronquio fuente derecho debido a traumatismo torácico cerrado / Right main bronchus avulsion due to thoracic blunt trauma

La incidencia de roturas traqueobronquiales secundarias a un traumatismo torácico cerrado es baja, y la mayoría de estos pacientes no llegan con vida a los centros de atención hospitalaria. La presentación clínica es variable dependiendo de la localización de las lesiones, los daños asociados y si las estructuras peribronquiales permanecen íntegras. Para su diagnóstico temprano se debe tener un alto índice de sospecha clínica y una correcta interpretación de los hallazgos semiológicos y radiológicos, lo que permite su rápida y correcta resolución. La demora en el tratamiento aumenta tanto la mortalidad como las complicaciones tempranas y tardías.

The incidence of tracheobronchial ruptures secondary to blunt thoracic trauma is low and most affected patients do not arrive alive to hospitals. Clinical presentation varies with the location of lesions, associated injuries and whether the peribronchial structures remain intact. Early diagnosis requires a high index of clinical suspicion and a correct interpretation of semiologic and radiologic findings, which allows for a rapid and correct resolution. Delay in treatment increases the mortality as well as early and late complications.

Parálisis del XI par craneal secundaria a enfisema subcutáneo por uso de pieza de mano de alta velocidad en cirugía de terceros molares / Paralysis of the XI cranial nerve following subcutaneous emphysema by use of high speed handpiece in third molar surgery

Introducción: La cirugía de los terceros molares es el procedimiento quirúrgico más frecuentemente realizado por los cirujanos orales y maxilofaciales, que a pesar de contar con una vasta experiencia y entrenamiento en el área quirúrgica pueden presentarse complicaciones transoperatorias y postoperatorias. Cuando éste es realizado por un cirujano dentista de práctica general las complicaciones pueden aumentar. Presentación de caso clínico: Se trata de un paciente de 25 años de edad sometido a extracción quirúrgica de terceros molares por un dentista de práctica general, el cual realiza procedimiento quirúrgico con uso de pieza de mano de alta velocidad. Tres días posteriores al evento quirúrgico el paciente acude al Departamento de Cirugía Oral y Maxilofacial del Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado por presentar edema, infl amación y crepitación en región bucal, maseterina y submandibular derecha, así como limitación a la apertura bucal de 25 mm. En tomografía computarizada contrastada se obs erva desviación de la vía aérea hacia el lado izquierdo. Se decide manejó del proceso infeccioso y de enfi sema subcutáneo con farmacoterapia y drenaje del mismo. Una vez remitido el enfi sema subcutáneo, en la cuarta semana de evolución el paciente refi ere limitación a la abducción del hombro derecho, observándose atrofi a del músculo trapecio y esternocleidomastoideo ipsilateral, correspondiente a lesión del XI par craneal. Discusión: La lesión del nervio accesorio (XI par craneal) ocasiona parálisis del músculo trapecio, principal estabilizador de la escápula que contribuye en los movimientos de fl exión, rotación y abducción del hombro. El trayecto del XI par craneal es superfi cial en el triángulo posterior del cuello presentando susceptibilidad a ser lesionado de manera iatrogénica, en este caso la utilización de pieza de mano de alta velocidad durante la extracción quirúrgica de los terceros molares generó enfi sema subcutáneo que condicionó la posible compresión del nervio accesorio, lesionando al mismo (AU)

Introduction: The third molar surgery is the most frequent surgical procedure performed by oral and maxillofacial surgeons, who despite their vast experience and training in the surgical area can present transoperatory and postoperative complications. When the oral surgery is done by a general practice dentist the complications can be increased. Case presentation: A 25-year-old male patient undergoing third molar surgery by a general practice dentist who performs a surgical procedure using a high-speed handpiece. Three days after the surgical procedure patient comes to the Department of Oral and Maxillofacial Surgery Institute for Social Security and Services for State Workers by present edema, swelling and crepitus in buccal space, masseteric and right submandibular region and limitation of mouth opening of 25 mm. Contrast computed tomography shows airway deviation to the left side. We decided to manage the infectious process and subcutaneous emphysema with antibiotic therapy and drainage. After subcutaneous emphysema was in remission, in the fourth week of evolution, the patient reported limitation of abduction of the right shoulder, with atrophy of the trapezius muscle and ipsilateral sternocleidomastoid, corresponding to a lesion of the XI cranial nerve. Discussion: Accessory nerve injury (XI cranial nerve) causes palsy of the trapezius muscle, the major stabilizer of the scapula that contributes to the fl exion, rotation and abduction movements of the shoulder. The trajectory of the XI cranial nerve is superfi cial in the posterior triangle of the neck presenting susceptibility to iatrogenic injury, in this case, the use of high-speed handpiece during the surgical extraction of the third molars, caused subcutaneous emphysema that conditioned the possible compression of the spinal nerve (AU)

Subcutaneous emphysema, a different way to diagnose / Enfisema subcutâneo: uma forma diferente de diagnosticar

Summary Introduction: Subcutaneous emphysema (SE) is a clinical condition that occurs when air gets into soft tissues under the skin. This can occur in any part of the body depending on the type of pathology. The most common site is under the skin that covers the chest wall or neck. It is characterized by painless swelling of tissues. The classic clinical sign is a crackling sensation upon touch, resembling that of touching a sponge beneath your fingers. Objective: To describe a new way to diagnose subcutaneous emphysema. Method: Our finding was a matter of serendipity while inspecting a patient with subcutaneous emphysema using a stethoscope. Instead only hearing the patient's chest, the stethoscope was gently pressed against the skin with SE and so we were able to detect a different sound. Results: This new way to diagnose subcutaneous emphysema consists in pressing the diaphragm part of stethoscope against the patient's skin where SE is supposed to be. Thus, we are able to hear a sound of small bubbles bursting. Crackle noise has an acoustic emission energy that varies between 750-1,200 Hz, considered high frequency. Conclusion: Although currently the use of imaging methods is widespread worldwide, we would like to strengthen the value of clinical examination. Auscultation is an essential diagnostic method that has become underestimated with the advances of healthcare and medicine as a whole. We therefore propose a different approach to diagnose SE.

Resumo Introdução: O enfisema subcutâneo é uma condição clínica que ocorre quando o ar entra nos tecidos sob a pele. Isso pode ocorrer em qualquer parte do corpo, dependendo do tipo de patologia. O local mais comum é sob a pele que cobre a parede torácica ou o pescoço. É caracterizado por inchaço indolor de tecidos. O sinal clínico clássico é a sensação de crepitação quando se toca a região afetada, assemelhando-se à sensação de se tocar uma esponja. Objetivo: Descrever uma nova maneira de diagnosticar enfisema subcutâneo. Método: Este achado foi uma serendipidade, caracterizada por inspeção clínica de pacientes com enfisema subcutâneo com uso de estetoscópio. Além da auscultação do tórax do paciente, o estetoscópio foi suavemente pressionado contra a pele com enfisema subcutâneo, sendo possível detectar um ruído diferente. Resultados: Essa nova maneira de diagnosticar enfisema subcutâneo consiste em pressionar o diafragma do estetoscópio contra a pele do paciente supostamente afetada por enfisema subcutâneo, sendo possível ouvir o ruído de pequenas bolhas estourando. O ruído de crepitações tem uma energia de emissão acústica que varia de 750-1.200 Hz, considerada alta frequência. Conclusão: Atualmente, o uso de métodos de imagem é generalizado em todo o mundo, mas gostaríamos de fortalecer o valor do exame clínico. Embora a ausculta seja um método de diagnóstico essencial, foi subestimado à medida que os cuidados de saúde e os medicamentos avançaram. Propomos uma maneira diferente de diagnosticar enfisema subcutâneo.

Sindrome de Hamman y anorexia nerviosa: presentación de un caso y revisión de la literatura / Hamman's syndrome and anorexia nervosa: case report and literature review

Presentamos el caso de una adolescente de sexo femenino quien cumple criterios clínicos de anorexia nerviosa y presenta dolor torácico, documentándose pneumomediastino espontáneo (PE). El PE se define como presencia de gas libre en el mediastino en ausencia de causa precipitante. La incidencia es muy baja pero heterogénea. Se presenta principalmente en la población pediátrica en especial durante crisis asmáticas; es mayor en el sexo masculino. La anorexia es una causa inusual y han sido descritos únicamente 20 casos en la literatura hasta el momento. Clínicamente, el síntoma principal es el dolor torácico, seguido de disnea y a la exploración física es importante reconocer signos específicos, de los cuales el más frecuente es el enfisema subcutáneo, así como el signo de Hamman considerado patognomónico. Esta es una patología con un curso generalmente benigno y su manejo en la mayoría de los casos es conservador, aunque sigue siendo un tema controversial.

This is a case report of a severely malnourished young female patient, who met clinical criteria for anorexia nervosa and developed chest pain in whom spontaneous pneumomediastinum (SP) was documented. SP is defined as the presence of free air or any other gas in the mediastinum in the absence of an obvious precipitating cause. The incidence is very low. Spontaneous pneumomediastinum occurs mainly in the pediatric population especially during asthma attacks, is greater in the male. Anorexia is an unusual cause and have been reported only 20 cases in the literature up to now. The main symptom is chest pain, followed by dyspnea and in the physical examination is important to recognize specific signs, of which the most common is the subcutaneous emphysema and Hamman’s sign, considered pathognomonic. This is a clinical entity with a generally benign course. Although it remains controversial in most cases its management is conservative

Spontaneous pneumomediastinum. case report

ABSTRACT Introduction: Spontaneous pneumomediastinum (SPM) is defined as the presence of air in the mediastinum. It is a rare entity considered benign and self-limiting, which mostly affects young adults. Its diagnosis is confirmed through clinical and radiological studies. Case description: 21-year-old male patient with cough and greenish expectoration for four days, associated with dyspnea, chest pain, fever and bilateral supraclavicular subcutaneous emphysema. Chest X-ray suggested pneumomediastinum, which was confirmed by tomography. The patient was hospitalized for observation and treatment. After a positive evolution, he was discharged on the sixth day. Discussion: SPM is a differential diagnosis in patients with chest pain and dyspnea. Its prevalence is lower than 0.01% and its mortality rate is low. It should be suspected in patients with chest pain and subcutaneous emphysema on physical examination. Between 70 and 90% of the cases can be identified by chest X-ray, while confirmation can be obtained through chest tomography. In most cases it does not require additional studies. Conclusion: SPM is a little known cause of acute chest pain, and rarely considered as a differential diagnosis; it is self-limited and has a good prognosis.

Enfisema subcutáneo generalizado más neumotórax a tensión posterior a CPRE / Generalized subcutaneous emphysema plus pneumothorax to tension after CPRE

La colangiografía retrograda endoscópica (CPRE) es una técnica invasiva que permite diagnosticar y tratar patologías de vía biliar. La tasa de complicaciones es baja volviendo al procedimiento seguro, no exento de complicaciones como pancreatitis, sangrados, colangitis e incluso perforación (incidencia menor al 1,5%). Se presenta el caso clínico de un paciente de sexo masculino, con dolor en hipocondrio derecho, vómito y fiebre que presenta dilatación del extremo distal del colédoco por causa litiásica evidenciado por colangioresonancia. Se programa para CPR intentándose la canulación sin papilotomía; durante el procedimiento el paciente presenta enfisema subcutáneo y neumotórax a tensión ameritando tratamiento de emergencia. Se decide manejo quirúrgico a las doce horas de la CPRE por la marcada inestabilidad hemodinámica del paciente; en el intraoperatorio y en una endoscopia ulterior no se evidenció una lesión macroscópica que justifiquen la clínica e imágenes radiológicas que presentó el paciente. Se realiza tratamiento quirúrgico de perforación duodenal que obligó una estancia en terapia intensiva durante 11 días. Se complementa con una revisión bibliográfica de las complicaciones post CPRE. (AU)

Endoscopic retrograde cholangiography (ERCP) is an invasive technique that allows diagnosing and treating pathologies of the bile duct. The rate of complications is low returning to the safe procedure, not free of complications such as pancreatitis, bleeding, cholangitis and even perforation (incidence less than 1.5%). We present the clinical case of a male patient, with pain in the right hypochondrium, vomiting and fever that presents dilatation of the distal end of the common bile duct due to lithiasic cause evidenced by cholangioresonance. It is programmed for CPR, trying cannulation without papillotomy; During the procedure, the patient presents subcutaneous emphysema and tension pneumothorax, requiring emergency treatment. Surgical management was decided twelve hours after ERCP due to the marked hemodynamic instability of the patient; In the intraoperative period and in a subsequent endoscopy, there was no evidence of a macroscopic lesion that justified the clinical and radiological images presented by the patient. Surgical treatment of duodenal perforation wasperformed, which forced a stay in intensive therapyfor11 days. It is complemented by a bibliographic review of post-ERCP complications. (AU)

Enfisema subcutáneo masivo, nemotórax a tensión y neumomediastino tras traqueotomía percutánea / Massive subcutaneous emphysema, nemotórax voltage and pneumomediastinum after percutaneous tracheostomy

Mujer de 68 años que ingresa en la Unidad de Cuidados Intensivos por shock séptico. En el posoperatorio la paciente se mantiene inestable y se decide realizar traqueotomía percutánea (TP) por intubación prolongada. Al inicio la paciente presenta un enfisema subcutáneo que progresa hasta convertirse en masivo. Se realiza TC torácico donde se observa pérdida de la morfología habitual de la pared posterior traqueal con solución de continuidad. Tras revisión mediante traqueobroncoscopía se decide colocar cánula de traqueotomía larga para dejar la lesión proximal al neumotaponamiento y así evitar la fuga de aire. Desde la colocación de la nueva cánula, la paciente presenta una disminución progresiva del enfisema hasta su total resolución. La TP es un procedimiento seguro que se realiza con mucha frecuencia en los servicios de medicina intensiva, sin embargo, no está exenta de complicaciones. En la revisión de Powell y cols describen las complicaciones de la TP destacando la inserción peritraqueal, la hemorragia, las infecciones de la herida, el neumotórax y la muerte. El rango de complicaciones en la literatura oscila entre 3% y 18%. Además, no se encuentran diferencias significativas respecto a las complicaciones entre la TP y la técnica abierta.

A 68-year-old woman who enter in intensive care unit due to septic shock. In the postoperative period, the patient remained unstable and decided to perform a percutaneous tracheotomy (PT) because prolonged intubation. In the first, the patient presents subcutaneous emphysema that progresses until becoming massive. Thoracic CT is performed where loss of the usual morphology of the posterior tracheal wall with continuity solution is observed. After revision by means of tracheobroncoscopia, it is decided to place a long tracheotomy cannula to leave the lesion proximal to pneumotaponamiento and thus avoid air leakage. From the placement of the new cannula, the patient presents a progressive decrease of the emphysema until its total resolution. PD is a safe procedure that is performed very frequently in the Intensive Care Services3, however, it is not without its complications. The review of Powell et al4 describes the complications of PT emphasizing peritracheal insertion, hemorrhage, wound infections, pneumothorax, and death. The range of complications in the literature ranges from 3 to 18% 5. In addition, no significant differences were found regarding the complications between the TP and the open technique.

Enfisema subcutâneo abrangendo os espaços temporal, orbital, bucal, submandibular e cervical após cirurgia para extração de terceiro molar / Subcutaneous emphysema envolving temporal, orbital, buccal, submandibular and cervical spaces after third molar surgery

Enfisema subcutâneo é uma complicação bem estabelecida de trauma ou infecção com pneumonia ou tuberculose, que tem incluído o aumento da pressão intrabucal no local de uma lesão da mucosa ou a provisão de ar comprimido em uma ferida. A incidência desse tipo de complicação tem aumentado consideravelmente, desde a introdução de peças de mão em alta rotação, usadas em cirurgias de terceiro molar. Este artigo tem como objetivo apresentar um relato de caso de um paciente do gênero masculino que foi submetido à cirurgia para remover o terceiro molar superior direito, com a ajuda de peça de mão em alta rotação, desenvolvendo um enfisema subcutâneo dos espaços fasciais no pós-operatório imediato. As imagens da tomografia computadorizada revelaram a presença de enfisema com dissecção do espaço periorbitário com envolvimento das pálpebras superior e inferior, espaços temporal e bucal, estendendo-se para a região submandibular, sublingual e cervical. A partir da descrição desse caso, os autores propõem uma forma de tratamento, evidenciando os meios de diagnóstico e prevenção dessa complicação... (AU)

Subcutaneous emphysema is a well-established complication of trauma or infection pneumonia and tuberculosis, which have included increasing the intraoral pressure at a site of the mucosal lesion or compressed air supply on a wound.

Síndrome de Hamman / Hamman syndrome

Resumen Se conoce como Síndrome de Hamman al neumomediastino espontáneo. Condición considerada benigna, autolimitada y poco reportada en la literatura nacional e internacional. Es probable que exista un subregistro o no se dé a conocer lo suficiente. Debe tenerse en cuenta en todo paciente joven que ingrese a los servicios de urgencias por dolor torácico, disnea y enfisema subcutáneo. El diagnóstico se realiza por sospecha clínica y se confirma con los rayos x de tórax. El tratamiento es netamente conservador. Presentamos un caso ilustrativo de esta condición que se presentó en un joven después de un episodio paroxístico de tos ocasionado por contacto con gasolina. Su condición previa era completamente normal. (Acta Med Colomb 2016; 41: 206-210).

Abstract Spontaneous pneumomediastinum is known as Hamman's syndrome. This condition is considered benign, self-limited and is little reported in the national and international literature. It is probably underreported or is not enough publicized. It must be considered in every young patient admitted to the emergency department with chest pain, dyspnea and subcutaneous emphysema. The diagnosis is made by clinical suspicion and is confirmed by chest X-rays. The treatment is clearly conservative. An illustrative case of this condition that occurred in a young man after a paroxysmal coughing episode caused by contact with gasoline is presented. Its previous condition was completely normal. (Acta Med Colomb 2016; 41: 206-210).
