Learning Objectives: To discuss the classification, preventio and treatment of pediatric retraction pockets.

Tympanic membrane retraction pocket (RP) is defined as an inward displacement of the TM from its normal position. It is characterized by partial collapse of the meso or epitympanic spaces, which correspond clinically to a retraction of a portion of the TM in its pars tensa (PT) or pars flaccida (PF). Even if several classification have been proposed, there is not a consensus in the treatment of this condition. The available classification systems will be reviewed as well as the medical and surgical treatment proposed.
