“…These phenomena are described as syndromic exorbitism in contrast with non-syndromic exorbitism (NSE) wherein no underlying cause can be found in the patient's medical history 2 . Although exorbitism can cause different aesthetic and functional eye debilitations for patients,2, 4 only a small number of studies have focused on precise definition, pathogenesis, and surgical operation success rate in exorbitism 4 …”

PurposeTo measure orbital dimension of patients with exorbitism and defining criteria for its diagnosis.MethodsTwelve patients with non-syndromic exorbitism (NSE) were compared with 24 control samples by means of computed tomography scan (CT-scan) findings. The proptosis severity, lateral wall length, medial wall length, optic nerve straight length, lateral wall angle, ethmoidal sinus surface area, mid-interorbital distance, anterior interorbital distance, external orbital distance, inter-pupillary distance, and lateral wall curve cord were evaluated in order to define a criterion for NSE.ResultsAmong eleven compared radiological parameters between the study and control groups, five parameters including lateral orbital wall angle (P = 0.02), mid-interorbital distance (P = 0.007), anterior inter-orbital distance (P < 0.001), inter-pupillary distance (P = 0.01), and proptosis severity (P < 0.001) were found to be significantly different between the study groups. Therefore, NSE could be diagnosed with lateral wall angle greater than 41.74°, mid-interorbital distance more than 31.84 mm, and anterior interorbital distance more than 25.90 mm, with a sensitivity of 91% and specificity of 71%.ConclusionsUsing lateral wall angle, mid-interorbital distance, and anterior interorbital distance, we defined the criterion for diagnosis of NSE. Moreover, by focusing on parameters which play a role in developing exorbitism, we can determine the best approach for improvement of aesthetic and functional features of this condition.

Airway management is one of the most important anaesthetist's skills as major complications of airway management, although rare, can be among the most life threatening in medicine. Crouzon syndrome is a rare condition with physical characteristics that can result in difficult airway manipulation. A correct preanaesthetic evaluation and a planned preinduction strategy should be designed to facilitate intubation.

“…The main aim of midface distraction 1 in conditions such as Aperts and Crouzon is to achieve increased orbital depth 2 and occlusion 3 simultaneously. The most important factor determining the success of this surgery is the vector of distraction.…”
