parrot beak tear

(redirected from Flap Tear)

The most common meniscal tear, a type of radial tear which begins at the free (inner) edge like other radial tears, but then curves into a longitudinal orientation—similar to longitudinal meniscal tears—as the tear extends toward the meniscal periphery. As the tear is traced on sequential MR images, it moves closer to the outer portion of the meniscus and then remains equidistant from the outer meniscal margin on subsequent images, as seen on longitudinal tears

par·rot beak tear

(par'ŏt bēk tār)

An injury to articular cartilage resulting in the separation of a narrow, curved wedge resembling a parrot's beak.

Mucosal flap tear was the most common complication encountered after endoscopic septoplasty which occurred in 4(7%) and was due to sharp spur, synechaiem in 3(5.2%), hemorrhage seen in 1(1.7%), septal perforation in 1(1.7%).

Out of 36 grade-3 medial meniscal tears, 9 (25%) tears were classified as horizontal tears, 4(11.1%) as vertical, and 15(41.6%) complex tears, 3(8.3%)-bucket handle, 3(8.3%) radial tear and 2(5.5%) as flap tear (Fig.

Flap tears (Figure 7) produce U or V shape breaks with the apex of the flap pulled into the vitreous cavity but still attached at the anterior border of the tear.
