BACKGROUND Adhesion formation is a frequent and serious post-operative problem in ENT surgery. This study assessed the effect of two anti-adhesive haemostatic agents on an experimental guinea pig model. METHODS The middle-ear mucosa of 14 guinea pigs was exposed to surgical trauma. After surgery, Arista™ AH was injected into the right middle ear of seven animals, while Ankaferd Blood Stopper was injected into the right middle ear of the other seven animals. The left ears were left untreated and regarded as the control group. The three groups were compared by histological examination at post-operative week 4. RESULTS In each of the three groups, consolidation of the lamina propria and epithelium mucosae, increments in the number of active fibroblasts, collagen fibrils and inflammatory cells, and increased vascular dilation were observed on haematoxylin and eosin-stained sections, and were more prominent in the control and Ankaferd Blood Stopper groups. Epithelial thickness and capillary vasodilation were significantly lower in the Arista™ AH group compared with the control and Ankaferd Blood Stopper groups (p < 0.008). CONCLUSIONS Arista™ AH may prevent the formation of adhesions in middle-ear surgery. Further experimental studies are required to determine its ototoxic potential.

D011183 Postoperative Complications Pathologic processes that affect patients after a surgical procedure. They may or may not be related to the disease for which the surgery was done, and they may or may not be direct results of the surgery. Complication, Postoperative,Complications, Postoperative,Postoperative Complication
D004432 Ear, Middle The space and structures directly internal to the TYMPANIC MEMBRANE and external to the inner ear (LABYRINTH). Its major components include the AUDITORY OSSICLES and the EUSTACHIAN TUBE that connects the cavity of middle ear (tympanic cavity) to the upper part of the throat.

D006168 Guinea Pigs A common name used for the genus Cavia. The most common species is Cavia porcellus which is the domesticated guinea pig used for pets and biomedical research. Cavia,Cavia porcellus,Guinea Pig,Pig, Guinea,Pigs, Guinea
D006490 Hemostatics Agents acting to arrest the flow of blood. Absorbable hemostatics arrest bleeding either by the formation of an artificial clot or by providing a mechanical matrix that facilitates clotting when applied directly to the bleeding surface. These agents function more at the capillary level and are not effective at stemming arterial or venous bleeding under any significant intravascular pressure.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
