The correct size airway is chosen by measuring the device on the patient: the device should reach from the patient's nostril to the earlobe or the angle of the jaw. [10] The outside of the tube is lubricated with a water-based lubricant so that it enters the nose more easily. [5] The device is inserted until the flared end rests against the ...
The oropharyngeal airway was designed by Arthur Guedel. [2]Oropharyngeal airways come in a variety of sizes, from infant to adult, and are used commonly in pre-hospital emergency care and for short term airway management post anaesthetic or when manual methods are inadequate to maintain an open airway.
The Eustachian tube (/ j uː ˈ s t eɪ ʃ ən /), also called the auditory tube or pharyngotympanic tube, [1] is a tube that links the nasopharynx to the middle ear, of which it is also a part. In adult humans, the Eustachian tube is approximately 35 mm (1.4 in) long and 3 mm (0.12 in) in diameter. [ 2 ]
Tornwaldt's disease is a rare benign disorder caused by persistent notochord remnants. [3] This disease almost remains asymptomatic. [citation needed] At about the 10th week of embryonic development, the pharyngeal pouch forms by adhesion of the pharyngeal ectoderm to the cranial end of the notochord.
A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent (open and unobstructed) airway. Tracheal tubes are frequently used for airway management in the settings of general anesthesia, critical care, mechanical ventilation, and emergency medicine. Many different types of ...
Adenoid hypertrophy, also known as enlarged adenoids refers to an enlargement of the adenoid (pharyngeal tonsil) that is linked to nasopharyngeal mechanical blockage and/or chronic inflammation. [1] Adenoid hypertrophy is a characterized by hearing loss , recurrent otitis media , mucopurulent rhinorrhea , chronic mouth breathing , nasal airway ...
On its lateral wall is the pharyngeal opening of the auditory tube, somewhat triangular in shape and bounded behind by a firm prominence, the torus tubarius or cushion, caused by the medial end of the cartilage of the tube that elevates the mucous membrane. Two folds arise from the cartilaginous opening:
Pharyngeal flap surgery has been completed in both children and adults. When younger children undergo the surgery, fewer speech impairments tend to occur. A possible explanation is that the earlier the surgery, the less likely the child will have developed compensatory strategies to overcome the velopharyngeal incompetence (Armour et al. , 2005).
