Sleep apnoea

Sleep apnoea

Obstructive Sleep Apnoea Syndrome (OSAS) is a disorder consisting of ‘apnoeas’, or breathing pauses, during sleep. These obstructive apnoeas are mainly caused by the collapse of the upper airway walls. OSAS affects more than 25% of the population and has a significant impact on the quality of life of the sufferer, whose sleep is not restful and who may experience daytime fatigue and an increased risk of accidents. Moreover, the chronic reduction of the levels of oxygen in the blood increases the risk of systemic diseases such as high blood pressure or insulin resistance.


The presence of two of the following symptoms in the absence of other causes could be an indicator of Obstructive Sleep Apnoea Syndrome:

  • Irregular, loud snoring with breathing pauses.
  • Daytime fatigue.
  • Chronic fatigue.

A definitive diagnosis is made by neurophysiologists using polysomnography, which monitors various parameters during sleep using special devices.


According to the most recent treatment guidelines, orthognathic surgery is the only procedure that can solve this problem immediately and definitively. This is not only confirmed by the results of more than 120 successful cases treated by Dr. Hernández Alfaro, but studies conducted by the team of maxillofacial surgeons at the Maxillofacial Institute, which have been published in prestigious international journals such as the Journal of Oral and Maxillofacial Surgery, also prove it. The articles describe how patients achieve an increase of 70% of the volume of their upper airways that lasts over time.

In addition, in comparison to the conventional approach, in which orthognathic surgery always includes prior orthodontic preparation, new protocols such as Surgery First allow some cases to be operated on first, with the orthodontic work being done later. This enables immediate correction of OSAS, and patients can decide the best time for them to have surgery.
