A frontal sinus fracture treatment algorithm is proposed and statistically validated. Nasofrontal outflow tract involvement with obstruction is best managed by obliteration or cranialization. Osteoneogenesis and fat obliteration are associated with unacceptable complication rates. Observation is safe when the nasofrontal outflow tract is intact.

The greatest epidermal, dermal and total skin thickness are found in the upper lip, right lower nasal sidewall, and left lower nasal sidewall respectively. The least epidermal skin thickness is in the posterior auricular skin. The least dermal skin thickness, and the least total skin thickness, are both in the upper medial eyelid.
