Abstract

Mastoidectomy forms the main surgical procedure for eradication of disease in chronic otitis media. Such a surgery which contemplates a complete exenteration of all the tympano-mastoid cavities is rightly considered as a difficult one mainly because a large number of vitally important structures are crowded together in the small field of operation and there is always a risk of damaging them. It is therefore, extremely important that the otologist who would undertake this surgery be thorough with the details of the surgical relations of this region. Out of the various structures seen on the lateral surface of temporal bone one very important structure is the suprameatal spine. It is shown to have great variations in shape and size and has been a mystery to researchers due to the implications it is known to have on mastoid region anatomy. In this study we have evaluated the various types of suprameatal spine, prevalence of each type and the effect of each to other landmarks encountered during surgery and also the effect of mastoid pneumatisation on the same.
