Clinical Head and Neck Flashcards
Pure tone audiometry
Determines the quietest sound (threshold of hearing) heard at each frequency in each ear.
Produces an audiogram
Tympanometry
Pushes air pressure into the ear canal, making the eardrum move back and forth, measuring its mobility.
Produces a tympanogram
Can assist in detecting: fluid in the middle ear, wax blockage or perforation
Pharyngeal pouch (Zenker’s diverticulum)
Herniation of the pharyngeal mucosa forming a pouch where food can lodge causing infection.
Presents as dysphagia etc.
Excised if large
Branchial cyst
An embryological remnant due to failure of fusion of branchial arches
Asymptomatic until infected when it presents as a solid painless mass, anterior to the sternocleidomastoid
Treatment: conservative or excision
Septal haematoma
A blood-filled cavity (usually bilateral) between the cartilage of the septum and the overlying perichondrium, usually caused by trauma.
As the cartilage relies on the blood supply of the perichondrium, if untreated this can lead to septum necrosis and perforation
Treatment = drainage
Premature fusion of cranial sutures
craniosynostosis
The brain doesn’t have space to grow so other structures bulge out
Rhinomanometry
Air is massed through the nose to measure the degree of nasal obstruction in each side of the nose
