Introduction:
Orthognathic surgery aims to treat facial dysmorphoses related to an anomaly of the maxillomandibular complex. This surgical treatment is most often performed in parallel with orthodontic treatment for functional and aesthetic purposes. In order to provide more efficient management and obtain a better stability of result, simple procedures must be added to orthognathic surgery to treat chronic nasal obstruction (CNO).
Materials And Methods:
The authors describe the techniques for surgical correction of CNO during orthodontic-surgical treatment and illustrate with some clinical cases.
Conclusions:
Restoration of nasal ventilation should be an objective of orthodontic-surgical treatment. CNO treatment can be performed at the same time as a maxillomandibular osteotomy.

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,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
