The posterosuperior retraction pocket, if allowed to progress will lead to
EUSTACHIAN TUBE OBSTRUCTION || PERSISTENT NEGATIVE PRESSURE IN THE MIDDLE EAR || ATTIC OR POSTEROSUPERIOR RETRACTION POCKET || PRIMARY ACQUIRED CHOLESTEATOMA Hearing is normal in atticoantral type when vesicular continuity is intact or when cholesteatoma, having destroyed the ossicles, bridges the gap caused by destroyed ossicles. Hearing loss is mostly conductive but sensory neural element may be added. (Ref: Textbook of diseases of ENT, PL Dhingra, 7th edition, pg no.79)
