Effectiveness of Volumetric Reduction of Middle Concha Bullosa by Crushing Technique in Chronic Nasal Obstruction.

To study the effectiveness of volumetric reduction of middle concha bullosa by crushing technique in chronic nasal obstruction cases on selection basis of 3Dimensional computed tomography measurements. Patients with complains of nasal obstruction underwent an Observational study. They were subjected to nasal endoscopy and computed tomography of paranasal sinuses with 3D size estimation of middle turbinate to confirm concha bullosa. 37 patients with unilateral/bilateral lesions were divided into 4 groups on the basis of ranged sizes. These were subjected to volume reduction by crushing technique with marsulizer under local/general anesthesia with necessary post-operative medications and the final outcomes were judged on basis for nasal endoscopy and computed tomography of paranasal sinus at 1 year. Out of 37 patients with total 42 concha bullosa, 5 had bilateral lesion. After crushing techniques, following results were obtained. In group A with pre-operative volume of concha between 0.60 and 0.80 ccm, 11 succeeded to achieve post-operative value of < 0.60 ccm. In group B, C, D with preoperative concha volume > 0.80 ccm all succeeded in achieving the post-operative value of < 0.60 ccm. 50% reduction in volume of concha occurred in 88% cases of group A and 100% in cases of other groups post-operatively at 1 year. Encouraging results with negligible consequences are ensued upon in case of chronic nasal obstruction due to concha bullosa by doing its volumetric reduction by crushing technique with marsulizer instrument.
