Acoustic impedance measurements and their importance in cleft palate patients. 1979

M M Arora, and V L Sharma, and S P Gudi, and C Balakrishnan

There is a high incidence of middle ear pathology in cleft palate patients, secretory otitis media being the most common lesion. Impedence audiometry gives more valid information about conditions in the middle ear, as confirmed by exploratory paracenteses. Impedance audiometry, therefore, should be done as a routine, wherever facilities exist, in conjunction with the clinical examination.

D010033	Otitis Media	Inflammation of the MIDDLE EAR including the AUDITORY OSSICLES and the EUSTACHIAN TUBE.	Middle Ear Inflammation,Inflammation, Middle Ear
D002971	Cleft Lip	Congenital defect in the upper lip where the maxillary prominence fails to merge with the merged medial nasal prominences. It is thought to be caused by faulty migration of the mesoderm in the head region.	Harelip,Cleft Lips,Harelips,Lip, Cleft,Lips, Cleft

D004432	Ear, Middle	The space and structures directly internal to the TYMPANIC MEMBRANE and external to the inner ear (LABYRINTH). Its major components include the AUDITORY OSSICLES and the EUSTACHIAN TUBE that connects the cavity of middle ear (tympanic cavity) to the upper part of the throat.

D000158	Acoustic Impedance Tests	Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance).
