title: The morphological features of major and accessory fissures observed in different lung specimens.
abstract: The current study reports the presence of accessory fissure and anomalies in the major fissure and lobation in both the right and left lungs. The results indicated that out 102 lung specimens observed in the dissection room 37.26% appeared to have fissural or lobation anomalies and 63% of the anomalies were described in the right lung. Fissural anomalies accounted for 28.44% while the lobation anomalies were observed in 8.82% of the specimens. The abnormal fissure that were observed included the left minor fissure 10.78%, incomplete horizontal fissure 7.84%, diaphragmatic fissure 7.84%, right minor fissure 0.98% and azygos fissure 0.98%. Further observation revealed that 5.88% of the right lungs appeared to have two lobes and 2.94% of the left lungs had three lobes. The current study indicates that the right lung is commonly affected with fissural and lobation anomalies and that the left minor fissure is the commonly occurring fissural anomaly. Documentation and familiarization of these anomalies remain to be important for making correct radiological diagnosis and also for proper surgical management of lung pathology.
