The optimal age for the maxillomandibular reconstruction is controversial; as of 2004, this classification has been used:Type I (mild) and Type IIa (moderate)           13–16 years
Type IIb (moderate to severe malformation)     at skeletal maturity
Type III (severe)                              6–10 years
When the teeth are cutting, the teeth should be under supervision of an orthodontist to make sure no abnormalities occur. If abnormalities like dislocation or an overgrowth of teeth are seen, appropriate action can be undertaken as soon as possible. Orthognatic treatments usually take place after the age of 16 years; at this point, all teeth are in place and the jaw and dentures are mature. Whenever OSAS is detected, the level of obstruction is determined through endoscopy of the upper airways. Mandibular advancement can be an effective way to improve both breathing and æsthetics, while a chinplasty only restores the profile. If a nose reconstruction is necessary, it is usually performed after the orthognatic surgery and after the age of 18 years. The contour of the facial soft tissues generally requires correction at a later age, because of the facial skeletal maturity. The use of microsurgical methods, like the free flap transfer, has improved the correction of facial soft tissue contours. Another technique to improve the facial soft tissue contours is lipofilling.
Recently, the first robot-assisted surgery was described.Another approach to treatment involves catheter-based embolisation, often preceded by phlebography to visualise the vein on X-ray fluoroscopy.Ovarian vein coil embolisation is an effective and safe treatment for pelvic congestion syndrome and lower limb varices of pelvic origin. Many patients with lower limb varices of pelvic origin respond to local treatment i.e. ultrasound guided sclerotherapy. In those cases, ovarian vein coil embolisation should be considered second line treatment to be used if veins recur in a short time period  i.e. 1–3 years. This approach allows further pregnancies to proceed if desired. Bilateral coil embolisation is not advised if a future pregnancy is possible. This treatment has largely superseded operative options.Coil embolisation requires exclusion of other pelvic pathology, expertise in endovascular surgery, correct placement of appropriate sized coils in the pelvis and also in the upper left ovarian vein, careful pre- and post-procedure specialist vascular ultrasound imaging, a full discussion of the procedure with the patient i.e. informed consent. Complications, such as coil migration, are rare but reported. Their sequelae are usually minor.If a Nutcracker compression (see below) is discovered, operative relocation of the renal vein should be considered before embolization of the ovarian vein. Stenting is not advised. Reducing outflow obstruction should always be the main objective. History
The entity was first described by Clark in 1964. Following initial scepticism and lively discussion in the medical literature, it is now recognised by many authors. == References ==
