Dehiscence of Facial Canal

Swayam Jothi . S

Abstract :

 Introduction: Physiological presence of fetal dehiscence of the facial canal has been observed. As early as 1949, Guild (1949) regarded such natural absence as a “not uncommon anomaly”. Henner & Buckingham (1956) listed dehiscence among the severe abnormalities encountered in otological surgery. Excellent descriptions usually with a report on evidence have been provided by Derlacki (1957), Shambaugh (1980); Kodres and Buckingham (1957) and Cawthorne (1969). Materials & Methods: 30 fetuses were used to expose 60 fetal temporal bones. In these the petrous part was dissected, decalcified and serial sections were taken. Observation: In 6 specimens the wall of the facial canal was found to be deficient in the medial wall of the middle ear. The deficiency was varying from a minimal area to a wider area. If there is dehiscence of the facial canal in the middle ear there can be unexpected post operative facial nerve complications. The nerve will be involved in middle ear infections.
