The patients endonasal exam revealed that the quadrangular cartilage
was deviated toward the cleft side.
In his technique, he had suggested removal of the quadrangular cartilage
, flattening it using a septal morselizer and placing it between the mucoperichondrial flaps.
We consider the most expedient in all cases to do a cut on a left-hand side, even at displacement of the first line or a dislocation of a quadrangular cartilage
After nasal suctioning of debris, examination of the septum revealed the presence of a 6-ram perforation along the anterior portion of the quadrangular cartilage
To create this flap, the surgeon first makes a hemitransfixion incision and elevates the mucoperichondrium on both sides of the remaining caudal quadrangular cartilage
back to the anterior margin of the perforation.
the junction of the dorsal quadrangular cartilage
and the perpendicular plate) is imperative in order to prevent nasal-tip collapse.
Analysis of biopsy specimens revealed some exposed bone and an absence of quadrangular cartilage
If there is no mucosal tear, blood can collect in the space between the perichondrium and the quadrangular cartilage
, causing a hematoma.
