Abstract

Background: The most frequent cause of the damage to the facial nerve is trauma of the bone face, which is quite common especially in highly industrialised countries. Reconstruction of these nerves is carried out only in specialist centres and does not give satisfactory results. Therefore, methods enabling better anastomosis are still being sought.
The goal of the research was clinical analysis of anastomosis after cutting the cranial nerve of the dog.
Material and methods: The extracranial stem of the facial nerve was anastomoted using own derived venous muff (experimental group) and by traditional end to end method (control group). After operation the dogs were observed for 6 months. The time of restoration of normal state of mimic muscles was observed.
Results: Results of the research were compared. In the experimental group, symptoms of normal functioning of the anastomosed nerve were detected seven days after operation. Total restoration of normal state of the mimic muscles was noted four weeks after operation. Anastomosis of the facial nerve using venous muff gave satisfactory results in a time two times shorter than the end to end method.
Conclusions: 1. Anastomosis of the cranial nerve using venous muff gives satisfactory results in a time two times shorter than the traditional method. 2. Anastomosis can be performed in each surgical ward. 3. This method does not require additional technical preparations.
