Obstruction of the maxillary ostium refers to a blockage in the opening of the maxillary sinus, which can impede normal drainage and airflow. This condition can lead to sinusitis, resulting in symptoms like facial pain, pressure, and nasal congestion. The obstruction may be caused by factors such as inflammation, infection, or anatomical variations. Treatment often involves addressing the underlying cause to restore proper drainage.
A paralytic ileus is caused by an obstruction of the intestine due to paralysis of the intestinal muscles. The obstruction does not have to be complete to cause ileus.

Intrinsic airway obstruction refers to a blockage of the airways caused by internal factors, such as inflammation, swelling, or the presence of foreign bodies. Conditions like asthma, bronchitis, or tumors can lead to narrowing or obstruction of the air passages, making it difficult for air to flow in and out of the lungs. This type of obstruction differs from extrinsic obstruction, which is caused by external factors like pressure from surrounding tissues or external objects. Effective management often involves addressing the underlying cause to restore normal airflow.
A low-lying cecum in the pelvis can be caused by various factors, including congenital anatomical variations, such as an abnormally long mesentery or laxity of the supporting structures. Additionally, conditions like pelvic organ prolapse or significant weight gain can contribute to the descent of the cecum. Chronic constipation or bowel obstruction may also lead to altered positioning of the cecum. This anatomical change can sometimes be associated with certain gastrointestinal disorders or surgeries.
A blocked bile duct is caused by biliary blockage caused by gallstones, inflammation of bile ducts, tumore, parasites or caused by diseases such as hepatitis and cirrhosis.
In Spanish stands for Enfermidad Pulmonar Obstruction Cronica. A progressive disease mainly caused by smoking.
