B. Indications of Injury to the NOE Complex Structures
In general, the subjective symptoms and objective signs of injuries to
the NOE complex will reflect the pathology evidenced by the specific
structures that are injured.
1. Symptoms (Subjective)
The subjective symptoms of injuries to the NOE complex include the
following:
y
y
Diplopia.
y
y
Nasal stuffiness.
y
y
Epistaxis.
y
y
Visual disturbances.
y
y
Pain.
y
y
Dizziness, vertigo.
y
y
Anosmia.
2. Signs (Objective)
a. Traumatic Telecanthus
The average interpupillary distance is 60–62 millimeters (mm), which
corresponds to an intercanthal distance of approximately 30–31 mm.
The diagnosis of traumatic telecanthus requires a measurement in
excess of those normative values (Figures 3.14 and 3.15). The pathology
can be either unilateral or bilateral, with the former more difficult to
measure.
