Background: The presence of fissures in the normallungs enhances uniform expansion and hence facili-tates more air intake. Accessory and incomplete fis-sures of varying depth can be seen in unusual locationsof the lung, delimiting abnormal lobes which correspondto the normal bronchopulmonary segments. The knowl-edge of anatomical variations of lung fissures is essen-tial for clinicians, surgeons, and for radiologist for rec-ognizing various images of related abnormalities be-cause an accessory or anomalous fissure can be mis-taken for a lung lesion or an atypical appearance ofpleural effusion. Aims and Objectives: The aim of thepresent study is to observe the variations of lung fis-sures in Indian population. Fifty pairs (right- 50; left-50) of lungs were used for this study. Each lung wasstudied carefully for number of fissures whether com-plete or incomplete or absent. Presences of accessoryfissures were noted. Results: We observed completeabsence of fissures in two right and left lungs. Acces-sory fissures were present in 38% right lungs and 32%in left lungs. Conclusion: Incidence of absence ofoblique fissure and accessory fissure was greater inour present work when compared our results with otherauthors. Considering this we feel that more elabora-tive study should be done on this topic which will throwmore light on this.
