Then few pieces of gelfoam
were put in middle ear to create bed for perichondrial graft.
Semi-solid (polyvinyl alcohol [PVA], Gelfoam
slurry, Embozenes) and liquid (glue) embolic agents were injected through the coaxial needle after withdrawing the stylet.
To date, there have been many debates concerning the best material used for embolization; however, there is a general consensus on the superiority of temporary materials (11, 12), such as autologous blood clots, gelfoam
, or sponge, with a minimal risk concerning complications, but unfortunately recurrences may be encountered.
Type 1 tympanoplasty was done by Wilde's Post Aural approach using Temporalis fascia as graft material placed by Underlay technique after proper clearance of disease from middle ear with anterior support of Graft by Gelfoam
. Wide cortical mastoidectomy was done and Ventilation was established in all the cases by clearing granulations/disease in attic/aditus/ antrum if any.
Topical administration of a saline-soaked gelfoam
over the site of neurorrhaphy+intraperitoneal saline
Since then, the administration of various kinds of drugs and materials such as autologous fat grafts, Adcon-L, polytetrafluoroethylene membrane, Gelfoam
, and fibrinolytic agents have been administered desperately to the surgical field to act as a barrier or reduce the epidural fibrosis formation around the dura matter and nerve roots.
Oral intubation preparations dislodged the blood clots leading to hemorrhage from anterior extraction site which had to be sutured after hemostatic agent (Gelfoam
, Pfizer, USA) was packed into the sockets before the intubation.
Several pieces of Gelfoam
soaked in ofloxacin were placed in the middle ear to support the tympanic membrane.
Embolic agents commonly used during this procedure were absorbable gelatin sponge particles (Gelfoam
, 1400-2000 [micro]m, Hangzhou Alicon Pharm SCI and TEC Co.
A small piece of absorbable biomaterial (Gelfoam
) was used as a scaffold to guide growth of new bone across the cleft palate.
The pituitary fossa closed at the end of the procedure with raised nasoseptal flap or dermal graft placed onto the bony defect, human tissue glue and gelfoam
placed over it.
A gelatin embolization (Gelfoam
, Pfizer, New York, NY) slurry was injected until slowed flow and pruning of the distal vessels was observed.
