MORPHOLOGICAL STUDY OF FISSURES AND LOBES OF LUNGS: CLINICAL IMPLICATIONS

Abstract

This study investigates the morphological variations in the fissures and lobes of human lungs, focusing on their anatomical structure, clinical implications, and challenges in surgical and diagnostic practices. The research was conducted at KIMS Medical College, where 50 cadaveric lung specimens were dissected, and 100 MRI scans of living patients were analyzed. The cadaveric specimens were selected based on availability and absence of major pathological lung diseases, while MRI patients were chosen from hospital records, excluding those with prior lung surgery or significant lung pathology. Variations such as incomplete fissures, accessory fissures, and absent fissures were identified. These anomalies affected surgical outcomes, increasing air leak risks, and led to radiological misinterpretations, where accessory fissures were confused with pneumothorax or fibrosis. The study highlights the importance of preoperative imaging and awareness of anatomical variations to improve surgical precision and avoid diagnostic errors.
