Abstract
Chronic Otitis Media (COM) of the squamosal type was primarily managed by performing a canal wall down mastoidectomy; however, the latter era otolaryngologist envisioned benefits in preserving the posterior canal wall. Our primary objective was to assess the disease specific quality of life following canal wall up (CWU) mastoidectomy and canal wall down (CWD) mastoidectomy surgery after a 6 month post-operative period. A prospective observational study was done from September 2017 to August 2018 where the charts of 380 patients from Christian Medical College, Vellore were reviewed. Details of patients above 18 years who had undergone the above surgeries for COM active squamosal disease from the period of January 2014 to December 2016; and had their post-operative follow up (average of 16 months) during the period of study were looked at. The CWU group had a significantly better disease-specific quality of life in the symptoms subscale than the CWD group (p value < 0.01). The CWU group showed a significant air-bone gap closure to 23.3 dB as compared to 27.7 dB in CWD (p value = 0.005). The recurrence rates were 4.5% (9 cases) in the CWU group and 3.9% (7 cases) in the CWD group, which was not statistically significant. Both CWU and CWD methods of mastoidectomy for COM squamosal type give comparable outcomes in terms of recurrence with the CWU group having a better disease-specific quality of life after surgery.
