Orthognathic surgery and nasal obstruction

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.
