Unlabelled:
Because stability is known as the fundamental key of the successful outcome of orthodontics treatment, this study investigated the stability of tongue, hyoid bone and airway dimensions at least two years after active treatment with Faramand functional appliance in patients with class II div 1 malocclusion.
Conclusion:
The present findings indicate that treatment with functional appliance has the potential to increase pharyngeal airway dimensions and changes in tongue and hyoid position. Importantly, these achieved changes seemed to be maintained in long-term, up to 4 years on average.

The Hyoid Bone
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.
Pharynx
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
