The bimanual examination for assessing instability in naso-orbitoethmoidal injuries.

A new technique is presented for examining patients suspected of having fractures in the naso-orbitoethmoidal region. It consists of a bimanual examination with a Kelly clamp intranasally and the opposite index finger externally. It has proven reliable in over 500 patient screenings to date. This technique is recommended as an addition to, and not a replacement for, the standard physical examination and radiologic evaluation of the maxillofacial trauma patient.
