Infrared tympanic thermometers (ITT's) measure the frequency of infrared light emitted by the tympanic membrane.
Dr. Baguant, ENT specialist comments, " Cotton buds can cause the formation of cerumen plugs by pushing cerumen toward the tympanic membrane.

From the Phascolomyidae, the two families, which may be collectively designated Phalangeroidea, differ by the circumstance that in the skull the tympanic process of the alisphenoid covers the tympanic cavity and reaches the paroccipital process.
Infrared tympanic thermometers (ITT 's) measure the frequency of infrared light emitted by the tympanic membrane.
Without taking steps to equalize pressure, the tympanic membrane could rupture, causing hearing loss.
Tympanic membrane Tympanic membrane temperature accurately mirrors oesophageal temperature and is a good indicator of core and brain temperature.
Unlike many bones in a whale 's skeleton, the tympanic bone is very dense.
Core temperature was assessed at presentation using a tympanic probe on patients over 65 years of age.
Myringotomy is a surgical procedure in which a small incision is made in the eardrum (the tympanic membrane), usually in both ears.
It is also called myringocentesis, tympanotomy, tympanostomy, or paracentesis of the tympanic membrane.
Tympanic membrane-The eardrum, a thin disc of tissue that separates the outer ear from the middle ear.
A perforated eardrum (tympanum perforation) is an opening or rupture in the eardrum (tympanic membrane), the thin membrane that separates the outer ear canal from the middle ear.
The eardrum (tympanic membrane) is a thin, semi-transparent membranous wall that stretches across the ear canal and separates the outer ear from the middle ear.
The external ear canal is a tube approximately 1 in (2.5 cm) in length that runs from the outside opening of the ear to the start of the middle ear, which is behind the tympanic membrane (eardrum).
Outer ear-Outer visible portion of the ear that collects and directs sound waves toward the tympanic membrane by way of a canal which extends inward through the temporal bone.
The tympanic process of the alisphenoid bone of the skull is short, not covering the cavity of the tympanum, nor reaching the paroccipital process.
Birds possess an ear-muscle which at least acts as a tensor tympani; it arises near the occipital condyle, passes through a hole into the tympanic cavity, and its tendon is, in various ways, attached to the inside of the membrane and the neighbouring extracolumellar processes.
The tibia and fibula are united inferiorly, the tympanic bulla is hollow and the infra-orbital foramen narrow.
The infra-orbital foramen is generally narrow, and the tympanic bulla hollow.
The third sub-family is that of the Microtinae, or voles, which are distributed all over Europe, Northern Asia and North America, and are characterized by the tympanic bulla of the skull being filled with honey-combed bony tissue, the small size of the infra-orbital foramen, and the deep pterygoid fossa on the palatal aspect.
In the skull the tympanic bulla is hollow, the pterygoid fossa shallow and the zygomatic arch slender, with a rudimentary jugal bone.
They have long hind limbs, large eyes and ears; and in correlation with the latter an enlarged auditory bulla to the skull, which is hollow and divided into a tympanic and a mastoid portion.
In the skull the lachrymal bone is large, the paroccipital process is directed vertically downwards and the tympanic bulla is hollow.
The three remaining families of the Hystricoidea, of which one is African while the other two are chiefly South American, are very closely allied and often brigaded in a single family group. In the Capromyidae, which includes only the South American and West Indian hutias, the South American coypu and the African cane-rats, the tympanic bulla of the skull is hollow, the par-occipital process straight, the lachrymal small, and the cheekteeth rooted, with deep enamel-folds; the first front toe Leing occasionally absent.
The Octodontidae, which are exclusively South American, differ from the preceding family by the tympanic bulla being filled with cellular bony tissue, and by the par-occipital process curving beneath it, while the cheek-teeth are almost or completely rootless and composed of parallel plates.
In the Oreodontinae or typical section of the family, which includes several genera nearly allied to Oreodon, the skull is shorter and higher than in the camels, with a swollen brain-case, a preorbital glandpit, the condyle of the lower jaw transversely elongated, the tympanic bulla hollow, and the orbit surrounded by bone.
As is always the case with large-eared animals, the tympanic bullae of the skull are of unusually large size; the size varying in the different genera according to that of the ears.
Although the present article does not discuss mammalian osteology in general (for which see Vertebrata), it is interesting to notice in this connexion that the primitive condition of the mammalian tympanum apparently consisted merely of a small and incomplete bony ring, with, at most, an imperfect ventral wall to the tympanic cavity, and that a close approximation to this original condition still persists in the monotremes, especially Ornithorhynchus.
The periotic and tympanic are welded together, but not with the squamosal.
The tympanic forms a tubular meatus auditorius externus directed outwards and slightly backwards.
The circular space on each side of the basi-temporal (bt.) is the opening of the anterior tympanic recess.
