What anatomical feature complicates resective osseous surgery near mandibular molars?

The external oblique ridge is a significant anatomical landmark in the posterior mandible, serving as the attachment site for muscles and influencing the contour of the bone. During resective osseous surgery near the mandibular molars, awareness of the external oblique ridge is critical because it can limit the amount of bone that can be safely removed without compromising the integrity of the surrounding structures. Removing bone too close to or over the ridge can risk damage to adjacent soft tissues and can affect the mechanics of occlusion.

Additionally, the presence of the external oblique ridge can dictate the angles and approaches that a surgeon must take during the procedure. Surgical maneuvers need to be performed with caution in this area to avoid complications, making the external oblique ridge a prominent factor for consideration in these surgical procedures. Understanding the relationship and orientation of the external oblique ridge to the molars is essential in planning and executing surgeries effectively while minimizing potential complications.
