This study found that individuals with obstructive sleep apnoea (OSA) have distinct craniofacial and pharyngeal anatomical differences. These include a narrower airway, larger tongue, and altered jaw structure, contributing to OSA.
Area of Science:
- Dentistry
- Sleep Medicine
- Anatomy
Background:
- Obstructive sleep apnoea (OSA) is a common condition linked to craniofacial anatomy.
- Understanding these anatomical factors is crucial for effective treatment.
Purpose of the Study:
- To identify specific craniofacial and pharyngeal anatomical factors associated with obstructive sleep apnoea (OSA).
Main Methods:
- A hospital-based, case-controlled study involving 99 OSA patients and matched controls.
- Upright cephalograms were used to analyze skeletal and soft tissue landmarks.
Main Results:
- OSA patients exhibited reduced maxillary and mandibular lengths, and a shorter intermaxillary space.
- Narrower nasopharyngeal airway, increased tongue size, larger soft palate, and inferior hyoid position were observed in OSA subjects.
Conclusions:
- Significant craniofacial and pharyngeal anatomical variations are directly related to obstructive sleep apnoea.
- These findings can inform diagnostic and therapeutic strategies for OSA.

NREM sleep comprises four progressive stages that seamlessly merge:
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
