Aural/Ear syringe: used to flush out anything like ear wax or foreign bodies from the external ear Toynbee's auscultation tube: Otoscope/Auriscope: to examine the external auditory canal and ear drum; used during aural toileting, removal of wax, myringotomy, stapedectomy and to dilate the stenosis of canal Mouth gag - •Doyen's mouth gag
Ear instillation is the process of introducing otic medication or other liquids into the ear canal. Proper care is needed in delivering such liquids.
A myringotomy is a surgical procedure in which an incision is created in the eardrum (tympanic membrane) to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear. A tympanostomy tube may be inserted through the eardrum to keep the middle ear aerated for a prolonged time and to prevent reaccumulation of fluid ...
Otorrhea (ear discharge) is the most common complication of tympanostomy tube placement, affecting between 25–75% of children receiving this procedure. [2] [6] [9] [10] Saline washouts and antibiotic drops at the time of surgery are effective measures to reduce rates of otorrhea, which is why antibiotic ear drops are not routinely prescribed.
This process is called embedding. [22] The substance used to embed tissue is embedding media, which is chosen depends on the category of the microscope, category of the micro tome, and category of tissue. [23] Paraffin wax, whose melting point is from 56 to 62°C, is commonly used for embedding. [22]
Tissue embedded within optimal cutting temperature compound (OCT), mounted on a chuck in a cryostat, and ready for section production. The frozen section procedure is a pathological laboratory procedure to perform rapid microscopic analysis of a specimen. It is used most often in oncological surgery. [1] The technical name for this procedure is ...
Paraffin impregnation was introduced in 1925, and the embedding of organs in plastic was developed in the 1960s. [citation needed] Body preservation methods current to the 21st century are cryopreservation, which involves the cooling of the body to very low temperatures to preserve the body tissues, plastination, and embalming.

The fluid or pus comes from a middle ear infection (otitis media), which is a common problem in children. A tympanostomy tube is inserted into the eardrum to keep the middle ear aerated for a prolonged time and to prevent reaccumulation of fluid. Without the insertion of a tube, the incision usually heals spontaneously in two to three weeks.
