They credited this change to a change in the posterior positioning of the tongue due to the crib therapy.Some of the side-effects of using a tongue-crib therapy is that this appliance may trap food,  causing inflammation around the appliance. Repeated contact of the tongue with the appliance may lead to an imprint on the tongue which will self-resolve when the appliance is removed. It is important to note that this type of therapy will only work in patients who do not have a skeletal open bite tendency. A skeletal open bite tendency may be addressed via surgery or other treatment. Blue Grass appliance
Its a type of appliance which is similar to Nance appliance, but instead of acrylic pad that rests on the anterior palate, this appliance has a plastic roller that patient can use their tongue to break their habit. This appliance is banded to the upper 1st molars and bars extend the appliance to anterior palate where the plastic roller is placed. Vertical pull chin cup
Hakan Iscan and others used vertical pull chin cup in 17 patients for 9 months where they applied 400g of force on each side. Compared to controls, they found that patients included in the experimental group had increased eruption of the mandibular incisors, decrease of the ramal inclination, decrease of the mandibular plane, increase of the overbite, decrease of the gonial angle and increase of the mandibular corpus inclination were found. They stated that vertical chin cup maybe effective in treating skeletal open bite patients. However, Pedrin et al.
Terson syndrome or Tersons syndrome is the occurrence of a vitreous hemorrhage of the human eye in association with subarachnoid hemorrhage. Vitreous hemorrhage of the eye can also occur in association with intracranial hemorrhage and elevated intracranial pressure (ICP). Intraocular hemorrhage can be a subretinal, retinal, preretinal, subhyaloidal, or intra-vitreal hemorrhage. Its likely cause is a rapid increase in ICP. The classic presentation is in the subhyaloidal space, which is beneath the posterior vitreous face and in front of the retina.In subarachnoid hemorrhage, 13% of patients have Tersons syndrome, which is associated with more severe SAH (higher Hunt-Hess score, a marker of severity), and risk of death is significantly increased.The first known report of the association was by the German ophthalmologist Moritz Litten in 1881. Still, French ophthalmologist Albert Tersons name is more commonly associated with the condition after a report by his hand from 1900. References
