Nasal septal abscesses (NSAs) occur between the mucoperichondrium and the nasal septum.
Even minor trauma may injure the nasal septum, which can lead to the development of a nasal septal hematoma or nasal septal abscess, defined as a collection of pus between the cartilaginous or bony nasal septum and its normally coapted mucoperichondrium or mucoperiosteum.
Hemorrhage from these vessels creates a hematoma between the mucoperichondrium and the septal cartilage, depriving the avascular cartilage of its blood supply.
Ambrus et al define a nasal septal abscess as a collection of pus between the bony or cartilaginous septum and its overlying mucoperiosteum or mucoperichondrium.
1,2) This process involves the collection of blood between the septal cartilage and mucoperichondrium.
The patient was not returned to the operating room for a resection of the mucoperichondrium once the diagnosis of a low-grade tumor was confirmed.
If cartilage remains in the septum posterior to the perforation, the proposed new surgical procedure will preserve the blood supply from the sphenopalatine artery to the mucoperichondrium and then to the attached underlying cartilage.
The surgeon creates a composite flap made up of mucoperichondrium and a "button" of attached cartilage (figure 2).
During the procedure, a well-defined, complete, bilateral erosion of the mucoperichondrium was noted (figure 2, A).
The case of our patient illustrates the potential for an impacted nasal magnet to rapidly cause pressure necrosis of the septal mucoperichondrium.
If a septoplasty is being performed concurrently with spreader graft placement, a bridge of mucoperichondrium should be left attached to the septum at the inferior edge of the spreader pocket.
Wide undermining of the skin soft-tissue envelope and septal mucoperichondrium is performed in order to achieve complete exposure of both the nasal bones and the deflected septum.
