Pneumatization Pattern in Squamousal Type of Chronic Otitis Media
To study the pneumatization pattern of mastoid bone in cases of squamousal type of chronic otits media and analyze pneumatization pattern of opposite normal ear in cases of unilateral chronic otitis media (COM). A total of 94 patients (104 ears) between the age group of 7–84 years attending the E.N.T outpatients, inpatients and casualty of Acharya Vinoba Bhave Rural Hospital, Sawangi (Maghe), Wardha, after applying inclusion and exclusion criteria were found suitable and hence selected for the present study and were subjected to bilateral X-ray mastoid (Schuller’s view). HRCT temporal bone done in selected 55 patients. On analyzing patients radiologically (X-ray mastoid), it was found that out 104 ears, mastoid was pneumatized in 2 (1.92 %) diploic in 20 (19.23 %) and sclerotic in 82 (78.85 %) ears. Contralateral mastoid of 70 normal ears, mastoid was pneumatized in 30 (42.86 %) diploic in 22 (31.43 %) and sclerotic in 18 (25.71 %) ears. Most of the diseased ear demonstrated non pneumatized mastoid (98.08 %) whereas contra lateral mastoid of 70 normal ear, showed significantly more pneumatization This difference is statistically significant (P value < 0.0001). Significantly more sclerosis and non pneumatization in the ear with COM of squamousal type than the healthy contralateral ear supports the environmental theory.
