[Emphysema after cochlear implantation - risk factors and therapeutic options]. / Emphyseme nach Cochlea-Implantation ­ Risikofaktoren und Therapieoptionen.

OBJECTIVE: In case of cochlear implantation seroma, hematoma, local wound infections or vertigo are rare but typical complications. In contrast, emphysema is seldom reported. They can occur after cochlear implantation both in the postoperative healing phase and years later. A therapeutic algorithm does not yet exist. METHODS: We report on 3 patients with subcutaneous emphysema in the area of the receiver-stimulator. An unsystematic review of the literature of cases with emphysema after cochlear implantation highlights possible risk factors and the therapeutic options. RESULTS: The 3 cases developed subcutaneous emphysema 2-11 month after cochlear implantation due to nose blowing or CPAP therapy in obstructive sleep apnea. The current literature reports another 35 cases of emphysema after cochlear implantation. Air insufflation via the Eustachian tube is the most frequently described cause. Diseases of the nose and sinuses, tube dysfunction and obstructive sleep apnea are potential risk factors. Pressure bandage, puncture, tympanic tubes, and surgical revision are common treatments. CONCLUSIONS: Most emphysema can be controlled by conservative methods such as pressure bandaging and behavioral instruction. Punctures should be avoided due to the risk of upcoming infections. The prophylactic use of antibiotics seems dispensable. Surgical revision should be considered especially in cases of pneumocephalus with suspected leakage in the dura. The coverage of the mastoidectomy by a bony cap can be precautious and beneficial in cases with risk factors.

Conservative Approach For The Management Of Bilateral Pneumothorax And Pneumomediastinum After Laparoscopic Totally Extraperitoneal Inguinal Hernia Repair.

Laparoscopic totally extraperitoneal inguinal hernia repair is considered a common and safe procedure. Here, we present the case of a 31-year-old male with right indirect inguinal hernia and no medical history. The patient underwent laparoscopic totally extraperitoneal inguinal hernia repair and the operation was completed successfully. During extubation, subcutaneous emphysema was noted at the neck, chest, and above the nipples. Tracheal injury was excluded by the anaesthesiologists and otorhinolaryngologists. On arterial blood gas, the patient's oxygen saturation was 95% with nasal oxygen support. The patient was followed-up closely in the general surgery inpatient clinic. Computed tomography was performed, on which bilateral pneumothorax and pneumomediastinum were noted. Conservative management was planned and the patient was discharged on the fourth postoperative day. Laparoscopic totally extraperitoneal inguinal hernia repair is considered a routinely applied safe procedure, however, appropriate care should be taken to avoid possible complications.

Pneumoperitoneum, pneumomediastinum and subcutaneous emphysema following argon plasma coagulation treatment of colonic angioectasia.

INTRODUCTION: The paper presents unusual symptoms as a complication of therapeutic colonoscopy. CASE REPORT: A 70-year-old polymorbid female patient in chronic dialysis program underwent argon plasma coagulation treatment of leaking angioectasias in the cecum and ascending colon. Shortly after the procedure she presented with shortness of breath and subcutaneous emphysema of the neck which was initially misdiagnosed as swelling. Further tests revealed pneumoperitoneum, subcutaneous emphysema and pneumomediastinum. Considering the high risks for our patient (comorbidities, obesity), a laparoscopic approach was indicated. During laparoscopy neither peritonitis nor intestinal perforation were found. The patient recovered without complications after further complex treatment. CONCLUSION: Shortness of breath and subcutaneous emphysema are not typically among the first symptoms of colonoscopic perforation. Our case confirms that we should bear this complication in mind and when suspected, the diagnostic process should be started without delay.

Pneumopericardium, pneumomediastinum and surgical emphysema in spontaneous pneumothorax.

Spontaneous pneumothorax leading to pneumomediastinum, pneumopericardium and surgical emphysema is a benign condition. Progression to the development of epidural pneumatosis is rare. We report a 19-year-old man who presented with dyspnoea and swelling of the chest wall following a bout of cough. Bilateral subcutaneous emphysema was palpated on the anterior chest wall from the sternum to the midaxillary regions. His chest X-ray revealed subcutaneous emphysema and pneumopericardium. His computed tomography of the thorax to rule out life-threatening conditions revealed bilateral subcutaneous emphysema, pneumomediastinum, pneumo-pericardium and pneumothorax. He was transferred to the intensive care unit. An intercostal drainage tube was inserted in the left pleural cavity. The patient was followed up with repeat chest X-rays. The patient's symptom got relieved and was discharged after day 9. Diagnosis of pneumomedia-stinum may not be as lamentable as it is seen. Close cardio-pulmonary monitoring is mandatory for complications and accompanying conditions. Most patients with uncomplicated spontaneous pneumomediastinum respond well to oxygen and conservative management. In this case, the patient's symptoms and severe tachypnoea prompted the insertion of an intercostal drainage tube.

Four Different Reasons of Subcutaneous Emphysema With or Without Pneumomediastinum and Pneumothorax After Facial Bone Surgery.

ABSTRACT: In the present study, the authors report rare case series with subcutaneous emphysema with or without pneumomediastinum and pneumothorax after orthognathic and facial bone contouring surgery, compare their clinical and radiologic findings, and suggest precautions. Four patients who showed subcutaneous emphysema on follow up chest X-ray and computed tomography after orthognathic and facial bone contouring surgery were included in the study. In all cases post-op subcutaneous emphysema were detected, however, the aspect and mechanisms of post-op air spread were all different. After the conservative management with administering the O 2 by nasal cannula or endotracheal tube, the symptoms were relieved except 1 patient who needed chest tube insertion and further supra-sternal incision. In conclusion, subcutaneous emphysema with or without pneumomediastinum and pneumothorax after orthognathic and facial bone contouring surgery can be occurred by cervical fascia injury or alveolar ruptures. To preventing those complications, traumatic naso-tracheal intubation, excessive positive pressure ventilation, intermaxillary fixation immediate after the surgery, and increase of intra-alveolar pressure of the patients should be avoided.

Hyperbaric oxygen for the treatment of severe subcutaneous and mediastinal emphysema after Renuvion/J-Plasma therapy®.

Subcutaneous and mediastinal emphysema are known complications of liposuction and body sculpting procedures. Treatment options are limited, and recovery is often prolonged. We discuss a case of severe subcutaneous and mediastinal emphysema after a skin-tightening procedure involving helium gas. The patient received one treatment of hyperbaric oxygen and was followed until symptom resolution. We review the known literature on hyperbaric oxygen therapy as a treatment for subcutaneous emphysema.

Traumatic subcutaneous emphysema of the hand/forearm: A case report.

Subcutaneous emphysema is commonly associated with infection caused by gas-producing organisms. In this case report, we describe a rare instance of traumatic subcutaneous emphysema of the hand and forearm caused by a puncture injury to the first web space of the hand. Our objective is to increase awareness of the potential for seemingly minor trauma to cause entrapment of significant air in subcutaneous tissues, thereby decreasing the likelihood that a clinically benign-appearing patient will be started down an unnecessarily aggressive treatment pathway. A 16-year-old, otherwise healthy white female, presented to the pediatric emergency room with an impressive amount of subcutaneous emphysema that developed over a 12-h period after sustaining an accidental laceration to the first web space of her right hand. She appeared nontoxic and had a clinically benign presentation. A comprehensive work-up was performed. She was splinted by the orthopedic surgery resident on call, and was admitted to the Pediatric Intensive Care Unit for overnight monitoring. She received tetanus vaccination and broad-spectrum antibiotics. The patient was discharged 2 days after admittance, with a splint applied to her right hand and forearm. She undertook home-based physical and occupational therapy. She had a pain-free range-of-motion in the right wrist, elbow and shoulder. The swelling in the right hand subsided completely. Although initially alarming, traumatic subcutaneous emphysema in an otherwise healthy patient from minor wounds (as featured in this case) does not necessarily mean one ought to proceed down an aggressive treatment algorithm. Careful evaluation of the patient's history, clinical examination findings, and determination of the Laboratory Risk Indicator for Necrotizing Fasciitis score can help guide physicians in the management of traumatic subcutaneous emphysema and potentially avoid unnecessary and costly interventions.

[SARS-CoV-2-associated pneumothorax, pneumomediastinum and soft tissue emphysema. Clinical implications based on a case series]. / SARS-CoV-2-assoziierter Pneumothorax, Pneumomediastinum und Weichteilemphysem. Klinische Implikationen anhand einer Fallserie.

The new coronavirus (SARS-CoV-2) that arose in 2019 causes a wide spectrum of symptoms and different courses of disease. Pneumothorax, pneumomediastinum and soft tissue emphysema are rare complications in patients with pulmonary involvement. They are the sequelae of severe, virus-induced structural changes of the pulmonary architecture. High pressure artificial ventilation aggravates the problem. Hence pneumothorax and ectopic air in soft tissues are indicators of extensive pulmonary damage. Therefore, efforts should be made to treat even very small or multiply recurrent pneumothorax by drainage procedures.

Successful Management Foreign Body Aspiration Associated with Severe Respiratory Distress and Subcutaneous Emphysema: Case Report and Literature Review.

The presence of a foreign body in the airway is a potentially life-threatening clinical condition that requires urgent medical attention. We present a case of a 12-year-old boy who presented in the emergency room with a history of an episode of choking after aspiration of a foreign body, followed by severe respiratory distress and subcutaneous emphysema. Chest radiography revealed hyperinflation data, pneumothorax, and subcutaneous emphysema data. The flexible bronchoscope examination showed the presence of an inorganic foreign body impacted on the carina with tracheal lesions and laryngeal edema. It was necessary to perform a tracheostomy for its definitive extraction. The gold standard in the treatment of foreign body aspiration is bronchoscopy; although, in children, the technique adopted continues to be controversial, flexible bronchoscopy can be effective and very useful.

[Subcutaneous emphysema after dental or stomatological treatment, rare complications or consequences of malpractice ?] / Emphysèmes sous-cutanés après soins dentaires ou stomatologiques, rares complications ou conséquences d'une mauvaise pratique ?

The occurrence of pneumomediastinum and subcutaneous emphysema following oral treatment is the result of the inappropriate use of dental equipment using pressurised air. However, their use in oral surgery, including dental extractions, continues nowadays. In addition to being a source of subcutaneous and pneumomediastinum emphysema at risk of infection, pneumatic instrumentation can also be a source of potentially serious gas embolisms. A thorough knowledge of this type of complication by the practitioners and the proper use of the instrumentation will enable a significant reduction of the incidence of theses complications.

La survenue de pneumomédiastins et d'emphysèmes sous-cutanés à la suite de traitements buccaux est le résultat d'une utilisation inadéquate de matériels dentaires utilisant l'air pressurisé. Leur usage dans des soins de chirurgie orale, dont les extractions dentaires, persiste néanmoins à l'heure actuelle. En plus d'être pourvoyeur d'emphysèmes sous-cutanés et pneumomédiastin à risque de surinfection, l'instrumentation pneumatique peut également être la source d'embolies gazeuses potentiellement graves. Une connaissance approfondie de ce type de complications par les praticiens ainsi que la bonne utilisation de l'instrumentation permettront une réduction significative de leur incidence.

Cervico-Thoracic Air Collections in COVID-19 Pneumonia Patients - Our Experience and Brief Review.

Introduction: Abstract COVID-19 (Coronavirus-19 disease), a new clinical entity caused by SARS-COV-2 infection, could explain the physiopathology of cervicothoracic air collections (pneumothorax, pneumomediastinum, and subcutaneous emphysema). Material and Methods: We conducted an 8-months retrospective analysis of a single-center SARS-CoV-2 cases associating pneumothorax, pneumomediastinum, and subcutaneous emphysema, either alone or combined. Results: All non-intubated patients with the complications cited above had a favorable outcome after pleural drainage, percutaneous drainage, and/or conservative treatment, while the intubated patients, with multiple comorbidities, have had an unfavorable outcome, regardless the chosen treatment. Pleural drainage was used for pneumothorax cases; pneumomediastinum with subcutaneous emphysema required insertion of subcutaneous needles or angio-catheters with manual decompressive massage. Conservative methods of treatment were used for patients with pneumomediastinum and medium or severe respiratory disfunction. Conclusions: Etiopathogenic classification of pneumothorax should include SARS-CoV-2 infection as a possible cause of secondary spontaneous pneumothorax due to COVID-19 pneumonia. Survival rate after the occurrence of these complications was small (18,75%), 4 of the patients were cured, 2 had a favorable outcome and 26 have died. Pleural drainage which is mandatory to do for patients with pneumothorax complication in COVID -19 pneumonia, doesn't change the prognosis for those with severe affecting lungs, because the prolonged ventilation and the other comorbidities have led to death in most of these cases.

[Negative Pressure Wound Therapy as a Treatment Option for Extensive Post-Trauma Subcutaneous Emphysema]. / Moznosti lécby rozsáhlého poúrazového podkozního emfyzému pomocí podtlakové terapie.

Subcutaneous emphysema can be a secondary complication of chest trauma or one of the complications of ruptured bullae in advanced chronic obstructive pulmonary disease. Massive subcutaneous emphysema impairs the respiratory mechanics and affects the venous returns of the head and neck. It can lead to respiratory insufficiency with the need for mechanical ventilation. The treatment should focus on the primary pathology. Nonetheless, in patients with subcutaneous emphysema as the only but serious symptom, the treatment can zero in solely on this complication. The standard procedure consists in the insertion of chest drain which does not necessarily have to lead to successful treatment results. The authors present a case study of a 77-year-old man with major comorbidities, with extensive subcutaneous emphysema after blunt chest wall trauma, in which respiratory insufficiency developed. The chest drain was ineffective. The solution was to apply subfascial negative pressure therapy infraclavicularly to the area of the pectoral muscle, which made the subcutaneous emphysema almost immediately subside and which substantially improved the clinical condition of the patient. Local negative pressure therapy can be used as the method of choice for treating massive subcutaneous emphysema in patients, in whom the standardised treatment by chest drain with active suction mechanism failed and the lung is expanded in the pleural cavity, and for whom surgery is far too risky. Key words: negative pressure wound therapy, subcutaneous emphysema, rib fracture.

Urgent Subconjunctival Needle Decompression for Orbital Compartment Emphysema Caused by Compressed Air Injury.

Orbital compartment syndrome is a critical ophthalmic emergency that needs urgent diagnosis and treatment to prevent permanent vision loss caused by optic nerve compression or retinal ischemia. In this article, we present a child with orbital compartment syndrome caused by orbital emphysema as a result of a rare type of ocular trauma and introduce a simple technique to decompress the pressure. The patient was a 4-year-old boy who experienced a compressed air blast to his left eye. He presented to the emergency department with a frozen globe, tight orbit, and chemosis, without any evidence of globe rupture, conjunctival laceration, and orbital bone fracture. Computed tomographic scan demonstrated extensive subcutaneous, intraorbital, and intracranial emphysema. The pressure was immediately relieved under intravenous sedation by inserting a 27-gauge needle into the chemotic subconjunctival space at the lower lid fornix, followed by gentle manipulation of the globe to help the air escape through the needle. Compressed air injury is a rare type of orbital trauma, and this patient constituted the youngest case ever reported in the English literature, to our knowledge. Air decompression through the conjunctiva as described in this article is a useful technique that can be applied by emergency medicine specialists with special caution for patients with orbital compartment syndrome and orbital emphysema caused by compressed air injury.

Surgical Emphysema in a Pediatric Tertiary Referral Center.

BACKGROUND: Laryngeal trauma in pediatrics is extremely rare; however, because of the smaller pediatric larynx, it can have catastrophic consequences. Following laryngeal trauma, surgical emphysema is a relatively common presentation. In pediatrics, it can be a life-threatening condition. Here we describe 2 cases of laryngeal trauma resulting in extensive surgical emphysema. CASES: The first case described involves bilateral pneumothoraces, airway compromise, and respiratory arrest and was managed with bilateral chest drains, intubation, and tracheostomy. The second case resulted in widespread surgical emphysema in a stable patient and was managed conservatively. Both cases were monitored closely for a period of time to ensure there were no further sequelae. DISCUSSION: Patients with laryngeal trauma resulting in surgical emphysema have the potential to deteriorate rapidly. Furthermore, surgical emphysema degrades the quality of ultrasound images, which may delay the diagnosis. If there are any concerns about the safety of the airway, then it should be secured definitively with either endotracheal intubation or emergency tracheostomy depending on clinical judgment. It is acceptable to monitor patients closely in a high-dependency unit setting if they are stable and do not show any evidence of laryngeal edema. CONCLUSIONS: We present 2 cases of laryngeal trauma that were dealt with effectively so that both patients made a full recovery. It is important to act quickly to secure the airway if there are any concerns about its patency. Stable patients with no evidence of laryngeal edema can be managed conservatively. Close monitoring is essential to prevent any potential airway compromise.

Pulmonary barotrauma during hookah diving: a case report.

When commercial sea harvesters have dive accidents, it is sometimes difficult to obtain an accurate dive history and make a definitive diagnosis. We report a sea harvest diver who dived to collect sea snails (Rapana venosa) by using a hookah dive system. He experienced mediastinal and subcutaneous emphysema due to interruption of breathing airflow. Thoracic computed tomography performed one year prior to the accident revealed paramediastinal subpleural blebs on both lung apices. Emphysema was resolved by administering normobaric oxygen.

Getting the wind knocked out of him - Report of a broncho-cutaneous fistula caused by staphylococcal pneumonia, and review of literature.

A broncho-cutaneous fistula (BCF) refers to the formation of an abnormal fistulous connection between the tracheobronchial tree and the cutaneous surface of skin. A rare occurrence in and of itself, the disease entity may have varied etiologies, and may or may not be associated with a broncho-pleural fistula. We describe a case of a young patient who developed a BCF as a complication of a necrotizing pneumonic process, and his subsequent clinical course. In so doing, we review the clinical features of this peculiar disease entity, analyzing the available medical literature similarities in etiology and variations in management strategies described in the literature thus far.

[Vac-therapy in the management of tension pneumomediastinum and subcutaneous emphysema]. / Vakuum-terapiya v lechenii napryazhennogo pnevmomediastinuma i podkozhnoi emfizemy.

Pneumomediastinum and subcutaneous emphysema are the main manifestations of gas syndrome in patients with tracheal injury. Traditional mediastinal decompression in case of tension emphysema is carried out through different types of cervical or transpleural mediastinotomy and subsequent passive drainage. Clinical observation of the use of VAC-therapy in the patient with injury of the membranous part of trachea followed by tension pneumomediastinum is presented. Cervicotomy with dissection of anterior mediastinum and installation of vacuum-assisted dressing were performed. Fast regression of subcutaneous emphysema and relief of pneumomediastinum were noted. There were no complications. The patient was discharged in 6 days after admission. Effectiveness of VAC-therapy in patients with tension subcutaneous emphysema and pneumomediastinum was confirmed.

Colonoscopy-assisted percutaneous sigmoidopexy: a novel, simple, safe, and efficient treatment for inoperable sigmoid volvulus (with videos).

BACKGROUND AND AIMS: Many patients with sigmoid volvulus are old with co-morbidities, making elective surgery prohibitive. Colonoscopic management is often successful but volvulus often recurs. We devised a method of colonoscopy-assisted percutaneous sigmoidopexy as an alternative method to prevent recurrence of sigmoid volvulus. This study aimed to assess its safety and effectiveness. METHODS: Patients with sigmoid volvulus American Society of Anesthesiologists physical status classification ≥3 or Barthel index <30 were included. We excluded patients with intestinal necrosis and those who were unable to be repositioned but who could undergo intestinal resection. Colonoscopy-assisted sigmoidopexy was performed under radiographic observation. First, a colonoscope was inserted to the fixation site. A site for percutaneous puncture of the colon was identified by transmitted illumination and finger pressure. An exploratory puncture through the abdominal wall was made with a 23-gauge cattelan needle with the patient under local anesthesia, followed by a skin incision. Sigmoid fixation was then performed using a 2-shot anchor device that allows the sigmoid colon to be sutured to the abdominal wall. Fixation was repeated at 5 to 10 sites (average 8.8). The primary outcome measurement was sigmoid volvulus recurrence within 12 months. The secondary outcome measurement was adverse events. RESULTS: Eight patients received colonoscopy-assisted sigmoidopexy, and no sigmoid volvulus recurred during the 12-month follow-up period. One case of postoperative subcutaneous emphysema was successfully managed with conservative therapy. CONCLUSION: Colonoscopy-assisted sigmoidopexy was an effective, safe alternative method to prevent the recurrence of sigmoid volvulus.

[Life-threatening subcutaneous emphysema after minor blow to the neck]. / Lebensbedrohliches Hautemphysem nach banalem Stoß gegen den Hals.

After a minor blow to the neck from the handlebars of a bike, a 5-year-old boy developed a massive subcutaneous emphysema with respiratory distress. Orotracheal intubation was performed. A computed tomography (CT) scan of the neck and thorax showed a pneumomediastinum and a bilateral pneumothorax. No injury to the large airways was identified. The patient was stabilized by insertion of chest tubes and controlled ventilation. The endoscopic examination of the trachea revealed a tear of the pars membranacea, which was successfully treated conservatively. The specific features of the injury and the airway management are discussed based on a review of the current literature.

The Unusual Presence of Gas From a Puncture Wound: A Case Report.

The presence of gas within soft tissues as suggested by plain film radiographs and magnetic resonance imaging is usually sufficient evidence for a gas-producing bacterial infection. A thorough clinical examination and history and tissue culture are necessary to better determine the source of the gas. However, despite the unremarkable physical examination findings, the present case of a plantar puncture wound rapidly developed gas in the tissues and warranted surgical exploration and repair. Delaying treatment in any case of potential gas gangrene can be limb- and life-threatening. Only later was it revealed by the patient's husband that the wound might have been contaminated soon after the injury from a source other than the puncture, which led to the early presentation of gas on the imaging studies.
