Can perichondrium or temporalis fascia add slight augmentation and fullness to bridge?

Fascial or perichondrial grafts can be used to camouflage irregularities and are most commonly used over the dorsum or tip. If augmentation or volume is required, these grafts can be combined with crushed or diced cartilage (from septum, ear or rib) to achieve the desired result. Camouflaging grafts are especially useful in patients with thin skin, however, the bony or cartilaginous irregularities in your nose may require correction to smooth out the area as opposed to the addition of further graft material. This is something you can discuss with your surgeon.

Temporalis fascia can help to soften inperfections but does not typically add a lot of projection unless combined with crushed cartilidge.  I would post a few photos for better advice.

Both  perichondrium and temporal is fascia are excellent grafting sources  for a revision rhinoplasty. The amount and nature of the defect will determine the best source of material to use. When there is a cartilage or bony deficiency, we usually use cartilage grafting to replace missing tissue. For many examples of cartilage grafts used in our rhinoplasty practice, please see  the link below

Temporalis fascia can provide mild augmentation and is a good choice to hide irregularities in some patients. However, I need to see pictures to determine if this is a good choice for you.
