Abstract

Apparatus and methods for the treatment of conditions including obstructive sleep apnea and/or snoring resulting from excessive nasal airway resistance are disclosed. A rapid maxillary expansion device (10) is fitted to teeth (12, 14) of the upper jaw, and by operation of the jack screw (20), the maxilla is expanded such that, usually, the intermaxillary suture opens. The expansion is maintained until the maxilla stabilizes, for example by new bone growth along the suture. In this way the minimum cross-sectional area of the nasal cavity increases, reducing nasal airway resistance and curing, or at least ameliorating, obstructive sleep apnea and/or snoring.

Claims

1. A method for the treatment of obstructive sleep apnea and/or snoring comprising the steps of:

identifying an individual that suffers from at least one condition selected from the group consisting of obstructive sleep apnea and snoring;

separating the intermaxillary suture of the individual; and

maintaining the separation until a gap formed thereby is occupied by new bone growth and an intermaxillary suture is reformed, resulting in an increased nasal airway volume.

2. The method claim 1, comprising the further step, following said identifying step, of clinically assessing that said individual is a suitable candidate for the treatment of the subsequent steps.

3. The method of claim 2, wherein clinically assessing said individual includes observing that said individual exhibits maxillary constriction.

14. A rapid maxillary expansion device when used to perform the steps of any one of claims 1 to 6 or 9 to 13.

4. A method for the treatment of obstructive sleep apnea and/or snoring comprising the steps of:

identifying an individual that suffers from at least one condition selected from the group consisting of obstructive sleep apnea and snoring;

securing an expansion device between opposed sides of the upper jaw of the individual;

expanding the expansion device to cause orthopaedic displacement of opposed sides of the upper jaw to achieve separation of the intermaxillary suture; and

maintaining the separation until the gap formed thereby is occupied by new bone growth and intermaxillary suture is reformed.

5. A method as claimed in claim 4, comprising the further steps of surgically performing a partial corticotomy of the buccal surfaces of the maxillae with or without extension to the piriform aperture or the pterygomaxillary fissure in conjunction with the step of expanding.

7. The method of claim 4, comprising the further step, following said identifying step, of clinically assessing that said individual is a suitable candidate for the treatment of the subsequent steps.

8. The method of claim 7, wherein clinically assessing said individual includes observing that said individual exhibits maxillary constriction.

6. A method as claimed in 4, whereby the expansion device is secured to one or more of the posterior teeth on opposed sides of the upper jaw.

9. A method for the treatment of the pathophysiological effects of mouth breathing resulting from maxillary constriction, the method comprising the steps of:

laterally expanding the maxilla; and

maintaining the maxillary expansion until a stable state of the maxilla is established.

10. A method for the treatment of obstructive sleep apnea and/or snoring comprising the steps of:

identifying an individual that suffers from at least one condition selected from the group consisting of obstructive sleep apnea and snoring;

laterally expanding the maxilla of the individual; and

maintaining the maxillary expansion until a stable state of the maxilla is established.

11. The method of claim 10, comprising the further step, following said identifying step, of clinically assessing that said individual is a suitable candidate for the treatment of the subsequent steps.

12. The method of claim 11, wherein clinically assessing said individual includes observing that said individual exhibits maxillary constriction.

13. A method for the treatment of obstructive sleep apnea and/or snoring comprising the steps of:

identifying an individual that suffers from at least one condition selected from the group consisting of obstructive sleep apnea and snoring;

laterally distracting the maxillae of the individual; and

maintaining the distraction until a stable state of the maxillae is established.

15. The method of claim 13, comprising the further step, following said identifying step, of clinically assessing that said individual is a suitable candidate for the treatment of the subsequent steps.

16. The method of claim 15, wherein clinically assessing said individual includes observing that said individual exhibits maxillary constriction.

17. A method for the treatment of obstructive sleep apnea comprising the steps of:

identifying an individual that suffers from at least one condition selected from the group consisting of obstructive sleep apnea and snoring;

separating the intermaxillary suture of the individual, the separation of the intermaxillary suture being surgically facilitated; and

maintaining the separation until a gap formed thereby is occupied by new bone growth and an intermaxillary suture is reformed, resulting in an increased nasal airway volume.

18. The method of claim 17, comprising the further step, following said identifying step, of clinically assessing that said individual is a suitable candidate for the treatment of the subsequent steps.

19. The method of claim 18, wherein clinically assessing said individual includes observing that said individual exhibits maxillary constriction.

20. A method for the treatment of obstructive sleep apnea and/or snoring comprising the steps of:

identifying an individual that suffers from at least one condition selected from the group consisting of obstructive sleep apnea and snoring;

performing and maintaining maxillary expansion on the individual until a stable state of the maxilla and decreased nasal airway resistance are achieved in the individual.

21. The method of claim 20, comprising the further step, following said identifying step, of clinically assessing that said individual is a suitable candidate for the treatment of the subsequent steps.

22. The method of claim 21, wherein clinically assessing said individual includes observing that said individual exhibits maxillary constriction.

23. The method of claim 20, further comprising the step of verifying that the at least one condition has been ameliorated or cured in the individual.

24. The method of claim 20, wherein the identifying step comprises determining whether the individual exhibits greater than or equal to seven AHI events per hour of sleep.
