Resumo
The sinuses of the posterior wall of the tympanic cavity are formed between the bony ridges, bridges and other osseous prominences, remnants of the tympanum widening process. Anatomical limits and relationships of these sinuses were observed in 100 human temporal bones. Many morphological variabilities were found due to different levels of development of the middle ear posterior wall. The most important sinuses of this complex are the Sinus tympani and the Facial Sinus (Facial recess) seen in all cases. The Lateral tympanic sinus is well-formed in 83% of the cases and the Posterior tympanic sinus in 20% of our series.
