Introduction: In pathologies of the spine involving dorsal vertebrae, it is a routine practice to go for left-sided thoracotomy. It is so because in this approach, we encounter the aorta before reaching the concerned dorsal vertebra which is easy to handle as compared to the inferior vena cava on the right-sided approach. This is because the aorta is a structure with thick muscular wall. However, there are conditions which demand right-sided thoracotomy for better outcome such as idiopathic scoliosis and dorsal spine tuberculosis (TB). The selection of side of thoracotomy should be done on case-to-case basis. Study Design: This was a prospective study of 10-year duration. Purpose: The purpose of the study was to analyze whether it is more rational to do thoracotomy from the right side than left for dorsal spine TB. Materials and Methods: The study was performed on 102 dorsal Koch patients with neurological deficit who required surgical decompression. Magnetic resonance imaging of those patients was analyzed. Seventy-two patients had predominant right-sided lesion. Left and central types of predominant results were in 19 and 11 patients, respectively. Among these 102 patients, 82 were operated with right-sided thoracotomy, whereas 20 were operated for left-sided thoracotomy. Preoperative and postoperative kyphosis angle (K angle), average surgical time, mean blood loss, and visual analog scale (VAS) score were calculated. The SPSS 17 software was used for the statistical analysis. Results: Right thoracic approach turned out to be better approach than left in dorsal Koch spine. The average surgical time and mean blood loss were less in the right thoracotomy than left. Postoperative K angle and VAS were improved in the right thoracic approach as compared to left. Conclusion: Tubercular debris in the dorsal spine predominantly is on the right side, and right thoracotomy gives better results as there is better decompression of lesion.
