Tympanoplasty can be performed through the ear canal (transcanal approach), through an incision in the ear (endaural approach) or through an incision behind the ear (postauricular approach). A graft may be taken to reconstruct the tympanic membrane. Common graft sites include the temporalis fascia and the tragus. The surgery takes 1 ⁄ 2 to 1 ...
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
Otoplasty (surgery of the ear) was developed in ancient India and is described in the medical compendium, the Sushruta Samhita (Sushruta's Compendium, c. 500 AD).The book discussed otoplastic and other plastic surgery techniques and procedures for correcting, repairing and reconstructing ears, noses, lips, and genitalia that were amputated as criminal, religious, and military punishments.
The ear is washed and a small incision made in the eardrum. Any fluid that is present is then aspirated, the tube of choice inserted, and the ear packed with cotton to control any slight bleeding that might occur. This is known as conventional (or cold knife) myringotomy and usually heals in one to two days. [13]
The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear.The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
The round window is situated below (inferior to) and a little behind (posterior to) the oval window, from which it is separated by a rounded elevation, the promontory.. It is located at the bottom of a funnel-shaped depression (the round window niche) and, in the macerated bone, opens into the cochlea of the internal ear; in the fresh state it is closed by a membrane, the secondary tympanic ...
Traditional tympanoplasty, usually using the microscope and performed through a 10 cm incision behind the ear lobe. This technique was introduced by Wullstien and Zollner [8] and popularized by the Jim Sheehy at the House Ear Institute. [9] Endoscopic tympanoplasty, usually using the endoscope through the ear canal without the need for incision.
Major causes are ear infections or conditions that block the eustachian tube, such as allergies or tumors. [3] Blocking of the eustachian tube leads to decreased pressure in the middle ear relative to the external ear, and this causes decreased motion of both the ossicles and the tympanic membrane.
