- 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
