There's a nice
article I found on Long Face Syndrome here. Of interest here is the note about thin cortical plates and the implication that has for compensatory orthodontics, especially if you'd like to keep your teeth later in life. A strong statement here:
For long face patients with no prospect for successful growth
modification, surgery is probably the only treatment option.
Orthodontic camouflage does nothing to improve the excessive
facial height and can even further worsen it. A patient with
a genuine long face problem who does not accept a surgical
treatment protocol is better off without any treatment
