Introduction: The classic anatomic description of the middle ear cleft consists of three structural sets : the mastoid, the tympanic cavity and the bony eustachian tube.

Aims and objectives: The author try to find out observations and arguments demonstrating and defending the original and personal concept of a specific portion (fitting) of the middle ear cleft, which consists in a morphofunctional partition that separates the middle ear cleft in two functional sets; in two different compartments : anteroinferior and posterosuperior.

Methods: After having reviewed the literature and from the perspective of our combined clinical and research experience, the authors shall critically evaluate the various factors that contribute to the morphofunctional partition of the middle ear cleft.

Results: This partition is an entity, with clinical and surgical implications, and is defined by distinct anatomic, organogenic, mainly histologic, histopathologic and clinic characteristics.

Conclusions: This original concept of a morphofunctional partition of the middle ear cleft contributes to a better understanding of the physiology of the middle ear cleft, as well as of the pathogenesis of otitis media.
