|
what is the typical angle of the internal nasal valve?
|
10 to 15 degrees
|
|
|
In rhinoplasty, when do you place speader grafts?
|
when the internal nasal valve angle is less than 10 degrees
|
|
|
In rhinoplasty, when do you do an alar base flap?
|
correction of vestibular stenosis accompanied by malpositioning of the alar base
|
|
|
When does vestibular stenosis accompanied by malpositioning of the alar base occur?
|
often occurs in patients undergoing secondary rhinoplasty procedures
|
|
|
In rhinoplasty, when are patterned composite grafts of auricular cartilage used?
|
in patients who have external nasal valve deformities that involve cartilage and vestibular skin.
|
|
|
In rhinoplasty, when are lateral crural strut grafts indicated?
|
indicated for correction of alar rim collapse and concavity or malpositioning of the lateral crura
|
|
|
anterior ethmoidal nerve enters the nose near what structure?
|
crista galli
|
|
|
what does the external branch of the anterior ethmoidal nerve supply?
|
supplies the skin of the nasal tip and alae
|
|
|
the internal branch of the anterior ethmoidal supplies sensation to what?
|
the septum and the internal nasal walls
|
|
|
what does the infraorbital nerve supply?
|
the cheek, lip, lower eyelid, and the upper gingiva
|
|
|
where can the nasopalatine nerve be found?
|
the nasal septum in a groove in the vomer
|
|
|
what does the nasopalatine nerve supply?
|
It supplies sensation to the septum and the hard palate.
|
|
|
what is the treatment for periostitis of the dorsal hump after rhinoplasty?
|
oral administration of an antibiotic to treat the infection. After the erythema resolves, the dorsal prominence can be surgically excised in 8 to 12 months
|
|
|
what structures comprises the internal nasal valve?
|
septum, the nasal floor, and the caudal portion of the upper lateral cartilage.
|
|
|
what manuevers can be done to increase projection of the nasal tip?
|
graft to the tip, suturing the medial crura, and placing a strut graft between the medial crura. In addition, the caudal margin of the septum and cephalic alar rim can be resected
|
|
|
what manuevers can be done to decrease projection of the nasal tip?
|
resecting the lateral and medial crura and the nasal spine
|
|
|
what procedure can be done to decrease alar flare and nasal base reduction?
|
Weir-type alar resection or nasal sill resection
|
