Management of the nasal apparatus in maxillary surgery.

Many patients requiring maxillary surgery for the correction of dentofacial deformities have pre-existing nasal airway obstructions.

Techniques for eliminating pre-existing nasal obstructions and of avoiding adverse effects on the nasal airway resistance after maxillary surgery are presented.
