A new craniofacial index score (CIS) can differentiate patients with obstructive sleep apnea syndrome (OSAS) from habitual snorers. This score uses simple measurements to identify individuals with or without OSAS.

Area of Science:

  • Medical Science
  • Otolaryngology
  • Sleep Medicine

Background:

  • Obstructive sleep apnea syndrome (OSAS) is linked to specific craniofacial characteristics.
  • Differentiating OSAS patients from habitual snorers is crucial for diagnosis and treatment.

Purpose of the Study:

  • To develop and assess the feasibility of a craniofacial index score (CIS).
  • To differentiate patients with OSAS from habitual snorers using CIS.

Main Methods:

  • Collected anthropometric measurements and lateral head radiographs from OSAS patients and habitual snorers.
  • Utilized thirteen cephalometric and four anthropometric measurements in a discriminant model to construct the CIS.
  • Analyzed variables including soft tissues, hyoid bone position, Body Mass Index, and soft palate length.

Main Results:

  • The developed CIS correctly classified 82.1% of the OSAS group and 86.7% of the snoring group.
  • Variables related to soft tissues, hyoid bone to mandibular plane, Body Mass Index, and soft palate length showed the highest predictive value.
  • The study demonstrated the effectiveness of CIS in distinguishing between the two groups.

Conclusions:

  • A craniofacial index score (CIS) can be effectively constructed from cephalometric and anthropometric measurements.
  • CIS shows feasibility in identifying subjects with and without obstructive sleep apnea syndrome (OSAS).
  • This index may serve as a valuable tool in the clinical assessment of OSAS.
