What is oblique fissure in lungs?

The oblique fissure, which extends from the costal to the mediastinal surface of the lung both above and below the hilum. It divides the left lung in an upper and a lower lobe and in the right lung, separates the inferior from the middle and superior lobes, and is closely aligned with the fissure in the left lung.

In which view oblique fissures are visible?

The left lung is divided into two lobes, upper and lower, by the oblique (major) fissure. Only the horizontal fissure is commonly seen on a frontal chest X-ray. The oblique fissures (also known as the major fissures) may be visible on lateral images.

Where does oblique fissure begin?

Its approximate position can be marked by a curved line on the thoracic wall that begins roughly at the spinous process of the T4 level of the thoracic spine, then crosses the fifth intercostal space laterally, and follows the contour of the right 6th rib anteriorly 1.

Where does the oblique fissure start and end?

The right lung has three lobes; superior, middle and inferior. The lobes are divided from each other by two fissures: Oblique fissure – Runs from the inferior border of the lung in a superoposterior direction, until it meets the posterior lung border.

Do both lungs have an oblique fissure?

The oblique fissures (also called the major fissures or greater fissures) are bilateral structures in both lungs separating the lung lobes.

Where is oblique fissure of lung?

What does the oblique fissure separate in the right lung?
