SinusitisCaldwell's view: Caldwell's view (or Occipitofrontal view) is a radiographic view of skull, where X-ray plate is angled at 20° to orbitomeatal line. The rays pass from behind the head and are perpendicular to radiographic plate.Paranasal sinuses: Sinus}}Underwood's septa: In anatomy, Underwood's septa (or maxillary sinus septa, singular septum)Maestre-Ferrín L, et al. Maxillary sinus septa: a systematic review.Mucocele: A mucocele is any dilatation (typically pathologic) with accumulation of mucus. Examples include:Orbital apex syndrome: Orbital apex syndrome, also known as Jacod syndrome, is a collection of cranial nerve deficits associated with a mass lesion near the apex of the orbit of the eye. This syndrome is a separate entity from Rochon–Duvigneaud syndrome, which occurs due to a lesion immediately anterior to the orbital apex.Honeymoon rhinitis: Honeymoon rhinitis is a condition in which the sufferer experiences nasal congestion during sexual intercourse.Pasteur point: The Pasteur point is a level of oxygen (about 0.3% by volume which is less than 1% of Present Atmospheric Level or PAL) above which aerobic microorganisms and facultative anaerobes adapt from fermentation to aerobic respiration.Endoscopy unit: An endoscopy unit refers to a dedicated area where medical procedures are performed with endoscopes, which are cameras used to visualize structures within the body, such as the digestive tract and genitourinary system.

NCDs can refer to chronic diseases which last for long periods of time and progress slowly.BacitracinLaryngitisExternal bacterial infection (fish): External bacterial infection is a condition found in fish.Dense artery sign: In medicine, the dense artery sign or hyperdense artery sign is a radiologic sign seen on computer tomography (CT) scans suggestive of early ischemic stroke. In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases.ErtapenemEthmoid sinus: The ethmoidal sinuses or ethmoidal air cells of the ethmoid bone are one of the four paired paranasal sinuses. They are a variable in both size and number of small cavities in the lateral mass of each of the ethmoid bones and cannot be palpated during an extraoral examination.Topical decongestant: Topical decongestants are decongestants applied directly to the nasal cavity. By applying them directly to the site of action, topical decongestants relieve nasal congestion while reducing the side effects associated with systemically-acting decongestants, such as high blood pressure.Streptomyces cyaneus: Streptomyces cyaneus is an actinobacterium species in the genus Streptomyces.Tympanocentesis: Tympanocentesis is the drainage of fluid from the middle ear usually caused by otitis media, by using a small-gauge needle to puncture the tympanic membrane, also known as the eardrum.Amoebic brain abscessSubdural empyema: Subdural empyaema is a form of empyema in the subdural space.Man flu: Man flu is a pejoratively used phrase that refers to the idea that men, when they have a cold, exaggerate and claim they have the flu.

Antibiotics are listed alphabetically within their class or subclass by their nonproprietary name.Moraxella catarrhalis: Moraxella catarrhalis is a fastidious, nonmotile, Gram-negative, aerobic, oxidase-positive diplococcus that can cause infections of the respiratory system, middle ear, eye, central nervous system, and joints of humans. It causes the infection of the host cell by sticking to the host cell using a Trimeric Autotransporter Adhesins (TAA).Amoxicillin
