Rationale: An open nasal airway establishes physiologic breathing and may minimize the use of the open oral airway. It should be remembered that when the mouth is open the lower jaw auto-rotates open and allows the tongue to fall back into the posterior airway space. In some patients improvement of the nasal airway may also improve CPAP tolerance and /or compliance.
Indications: Nasal airway blockage caused by bony, cartilaginous or hypertrophied tissues that interfere with nasal breathing during sleep.
Techniques: Septal and /or bony intranasal reconstruction, alar valve or alar rim reconstruction, turbinectomy.
Clinical Outcomes: The ease and high success rate of nasal reconstruction makes this procedure a very valuable technique. It may not make a significant impact on moderate or severe SDB, such as the improvement seen with other procedures (palatal or tongue base surgery). However, it is still an essential part of the upper airway that should not be ignored in the overall treatment of SDB.
