These include the overlay tympanoplasty, (5) the underlay tympanoplasty, (6) over underlay tympanoplasty, (7) Gelfilm
sandwich tympanoplasty, (4) Crown cork tympanoplasty, (8) swinging door tympanoplasty, (9) laser assisted spot welding techniques, (10) and microclip techniques (11) and others like the fascial pegging, (12) annular wedge tympanoplasty, (13) loop tympanoplasty (14) which are but modifications of the basic technique.

disc was used to cover the denuded promontory.
These problems occurred in spite of the use of gelfilm
, stents, and other spacers, he said.
A drop of autologous PRP was placed on the Gelfilm to make it wet and to be adherent to the tympanic membrane (Figure 3).
Out of 35 perforations, 18 were subjected to chemical cauterization and 17 to freshening and application of Gelfilm patch and platelet rich plasma.
Younis: Gelfoam, Gelfilm
, paper, and tape have all been used to patch perforations following tube removal, and I don't know if there is any consensus as to whether one is better than another.
The absorbable dressings may be derived from number of materials and include Blood products (Fibrin glue, Floseal), Animal based (Hyaluronic acid based products like Sepragel, Merogel, Gelfilm
, Surgiflo), Plant based (Surgicel, carboxy methyl cellulose), Synthetic (Nasopore).
At the end of the procedure, a rolled-up Gelfilm
splint can be inserted into the surgically widened middle meatus to help keep the space open (figure, D).
splints were then placed between the middle turbinate and the lateral nasal wall on both sides (figure, C and F).
can be rolled into a multilayered stent and placed in the middle meatus (figure, A).
