The forehead flap is known as the best donor site for repairing nasal defects because of its size, superior vascularity, skin color, texture and thickness.

Other spangenhelms include a full face mask. The spangenhelm was an effective protection that was relatively easy to produce. Weakness of the design were its partial head protection and its jointed construction. It was replaced by similarly shaped helmets made with one-piece skulls (nasal helms), kettle hats and eventually the great helm or casque.

Nasal surgery is a specialty including the removal of nasal obstruction that cannot be achieved by medication and nasal reconstruction. Currently, it comprises four approaches, namely rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, targeted at different sections of the nasal cavity in the order of their external to internal positions.
