Association of various factors related to mastoid buffer and middle ear ventilation in etiopathogenesis of squamous chronic otitis media—a cross-sectional study

Abstract Background Active squamous chronic otitis media (COM) is an entity with a deep retraction pocket of the pars tensa or flaccida that has retained debris epithelial where fundus cannot be visualized involving tensa, associated cholesteatoma. Eustachian tube dysfunction (ETD) known etiological factor for COM, based on Wittmack’s theory; however, there are very few recent studies in this regard. Contracted mastoid pneumatisation (diploic primary sclerosis) and presence Korner’s septum have also been implicated to middle ear pathology, conflicting results. Hence, present study was undertaken find out association three important factors, namely eustachian dysfunction, type pneumatisation, related buffer ventilation etiopathogenesis active media. The attempted identify various conditions nose nasopharynx ETD. This would enable us appropriate surgical decision making long term benefits hearing disease outcomes. Results Out total 37 patients, media, it observed found 23 (62.16%). majority patients had diploic/primary sclerosed pneumatization pattern which 32 (86.48%) patients. 13 (35.13%) All these findings were statistically significant. Conclusion In study, we significant positive all factors contracted (diploic/primary sclerotic mastoid), causation occurrence diploic seemed most constant association. mechanical type, nasal pathologies, common was, deviated septum.
