Background: Limited data are available on the mortality rates of patients receiving extracorporeal membrane oxygenation (ECMO) support for coronavirus disease 2019 (COVID-19). We aimed to analyze the relationship between COVID-19 and clinical outcomes for patients receiving ECMO. Methods: We retrospectively investigated patients with COVID-19 pneumonia requiring ECMO in 19 hospitals across Korea from January 1, 2020 to August 31, 2021. The primary outcome was the 90-day mortality after ECMO initiation. We performed multivariate analysis using a logistic regression model to estimate the odds ratio (OR) of 90-day mortality. Survival differences were analyzed using the Kaplan–Meier (KM) method. Results: Of 127 patients with COVID-19 pneumonia who received ECMO, 70 patients (55.1%) died within 90 days of ECMO initiation. The median age was 64 years, and 63% of patients were male. The incidence of ECMO was increased with age but was decreased after 70 years of age. However, the survival rate was decreased linearly with age. In multivariate analysis, age (OR, 1.048; 95% confidence interval [CI], 1.010–1.089; P = 0.014) and receipt of continuous renal replacement therapy (CRRT) (OR, 3.069; 95% CI, 1.312–7.180; P = 0.010) were significantly associated with an increased risk of 90-day mortality. KM curves showed significant differences in survival between groups according to age (65 years) (log-rank P = 0.021) and receipt of CRRT (log-rank P = 0.004). Conclusion Older age and receipt of CRRT were associated with higher mortality rates among patients with COVID-19 who received ECMO.

Primary thyroid lymphoma is a rare malignancy that can grow rapidly and compress the airway. In such cases, a tracheostomy or thyroidectomy is generally required. Here, we report a case of a 76-year-old woman diagnosed with primary thyroid diffuse large B-cell lymphoma (DLBL), with dyspnea attributed to tracheal compression by the enlarged thyroid. The patient’s poor general condition meant that thyroidectomy was considered challenging. Therefore, a temporary endotracheal silicone stent was successfully inserted to maintain the airway, as tracheal stenting has been shown to be an effective treatment for both benign and malignant obstructive airway diseases. We conclude that, in patients with primary thyroid DLBL who present with airway compression but are not eligible for surgery, tracheal stent insertion can maintain the airway and allow time for chemotherapy to be administered.

Aspiration, the entry of material into the airway below the true vocal folds, has been reported in various type of postsurgical head and neck patients. The important of correctly identifying the cause of aspiration in the head and neck surgical patient. Clearly each cause represents a different physiologic or anatomic disorder which requires different management strategy. We discuss about the cause of aspiration during head and neck treatment.

As population ages, much more elderly patients have been diagnosed with head and neck cancer especially in Korea. Diverse factors such as comorbidities and disabilities make the establishment of evidence-based guidance more challenging. Chronological age, literally measured in days, months and years from the time the individual was born, is not an ideal predictor in determining personal health condition; individualization of treatment protocols with identifying the concept of frailty is the key to produce an advanced treatment plan of elderly patients suffering from head and neck malignancy. Frailty is a type of geriatric syndrome which refers to the status with age-associated declines in physiologic function and increased vulnerability to stress conditions independent of age. Therefore, screening the status of frailty may be beneficial for the elderly patients to determine decent treatment option and maximize the efficiency. In order to provide otolaryngologists prognostic information adapting the concept of frailty, research papers published from 2000 to 2018 are comprehensively reviewed in this article. For optimal care of elderly patients with head and neck cancer, frailty is definitely required to be assessed in order to establish an ideal treatment option and increase the efficacy of the treatment.

Ceruminous adenoma is a benign neoplasm of the ceruminous gland, and its development in human external auditory canal is very rare. Due to the limited number of cases, controversy still exists about nomenclature, classification, diagnosis and its treatment. Recently we experienced a 55 years old woman who was diagnosed with ceruminous adenoma of the external auditory canal, and who was treated with wide excision. So we report this uncommon case in combination with a review of the literature.

Actinomycosis is a slowly progressive, chronic infectious disease. It is caused by the genus Actinomyces, which are gram-positive anaerobic bacteria. It presents as a mass-like lesion, composed of bacterial nidus and characteristic granulomatous inflammatory fibrosis. As such, it has frequently been mistaken for a malignancy. Surgical resection is a common procedure in these patients prior to a definite diagnosis. Although actinomycosis can occur in a variety of regions, including oral-cervicofacial, thoracic, and abdominopelvic cavities, the involvement of the pancreas is very rare. We report a case of a 44-year-old male with a symptomatic actinomycosis caused by a mass in the tail of the pancreas. The diagnosis was made using an endoscopic ultrasound-guided fine needle aspiration biopsy without surgical resection. After the treatment with antibiotics, the pancreatic mass was confirmed to be resolved on the follow-up computed tomography.

Small cell carcinoma commonly originates in the lung, with only about 4% of cases arising at extrapulmonary sites. Furthermore, small cell carcinoma of the sinonasal tract is extremely rare. In Korea, only 2 cases of primary sinonasal small cell carcinoma have been reported in the nasal cavity and the nasal septum, respectively. Recently, we have experienced a rare case of small cell carcinoma arising from the right maxillary sinus coexisting with a fungal ball lesion. Herein, we report this case with a review of the literature.

Marginal zone B-cell lymphomas are indolent lymphomas that arise from the memory B cells in the marginal zone of lymphoid tissue. They include mucosa-associated lymphoid tissue lymphoma, splenic marginal zone lymphoma, and nodal marginal zone lymphoma. These three subtypes share morphologic and immunophenotypic features, but can be distinguished by primary site at presentation. Recently, we experienced a rare case of primary nodal marginal zone lymphoma that arose from an intra-parotid lymph node. So we report this case with a review of literature.

Primary cartilaginous tumors of the laryngeal lesion are rare and it accounts for only 1% of laryngeal tumor pathology. They are most commonly located on the endolaryngeal surface of cricoid cartilage, and it is extremely rare to find them in vocal muscle lesion. In most cases, treatment of choice is based on surgical excision, and postoperative radiotherapy is typically recommended. We experienced a case of a 22-year-old young woman without underlying disease, presenting extraskeletal myxoid chondrosarcoma of vocal cord, especially in the vocal muscle. The patient underwent mass excision through suspension laryngoscope and radiation therapy.
