Morphological anatomy of accessory fissures in lungs.
BACKGROUND
Knowledge of the position and grade of accessory fissures and lobes is necessary for appreciation of lobar anatomy and thus locating bronchopulmonary segments.


METHODS
Morphological variations of accessory fissures and lobes of the lungs were studied in 40 pairs of lungs from cadavers.


RESULTS
Four left-sided lungs and two right-sided lungs showed accessory fissure in the lower lobe. Only one accessory fissure of left lung belongs to grade-ii and the remaining belongs to grade iii. [According to Craig and Walker's fissural classification]


CONCLUSIONS
Awareness regarding accessory fissures and lobes is essential for performing lobectomies, segmental resection, for differential diagnosis and interpreting radiological images.
