Type II tympanoplasty is used for tympanic membrane perforations with erosion of the malleus. It involves grafting onto the incus or the remains of the malleus
Supernovae are classified as Type I or Type II depending upon the shape of their radioactive decay of the unstable heavy elements produced in the explosion.
Massive stars, typically with a mass greater than 8 times that of our Sun, explode in a type II supernova. These stars undergo a core collapse followed by a massive explosion, resulting in the release of vast amounts of energy and debris into space.
Betelgeuse is expected to end its life in a supernova explosion, likely as a Type II supernova due to its massive size and age. This type of supernova occurs when a massive star exhausts its nuclear fuel and collapses under its own gravity.
if you say copper(II) then it means that you are denoting a atom with +2 as valency. and copperIII) means u denote this atom with +3 as valency
Type II compounds typically involve metal atoms that can form ionic bonds with nonmetals. Metals that do not commonly participate in these types of compounds include noble metals like gold (Au) and platinum (Pt), as they tend to be resistant to oxidation and do not easily form ions. Therefore, either of these metals would not be involved in the formation of a type II compound.
Type III tympanoplasty is indicated for destruction of two ossicles, with the stapes still intact and mobile. It involves placing a graft onto the stapes, and providing protection for the assembly.
Type IV tympanoplasty is used for ossicular destruction, which includes all or part of the stapes arch. It involves placing a graft onto or around a mobile stapes footplate.
An incision is made into the ear canal and the remaining eardrum is elevated away from the bony ear canal, and lifted forward. The surgeon uses an operating microscope to enlarge the view of the ear structures.
tympanoplasty (reconstruction of the ear drum),Tympanoplasty =Surgical modification of the eardrum.
For tympanoplasty with ossicular reconstruction, the patient usually stays in the hospital overnight
