Brief Summary

CBCT is considered an innovative imaging modality that can view the upper respiratory airway anatomy in a 3D manner. Recent studies tried to evaluate the accuracy of CBCT in analyzing the upper respiratory airway and its related structures. Although, most of these studies aimed to evaluate the 3D imaging of upper respiratory airway in OSA patients and their healthy counterparts, the determination of its level of collapse with the aid of CBCT wasn't clearly evaluated. DISE is considered a dynamic approach to determine the level of upper respiratory airway collapse accurately, but CBCT can offer better evaluation of anatomical upper respiratory airway characteristics and morphology which in turn affects treatment planning and patients' satisfaction after surgery. The hypothesis is agreed with other studies who found that retroglossal collapse appears more frequently during the end of expiration imaged by dynamic MRI. Our hypothesis is the validity of CBCT in determining the level of collapse through assessing different orthogonal planes at end of inspiration and expiration especially in those patients having a tongue/palate interaction or lengthy palate where this anatomical variation wasn't been probably evaluated with DISE.

Obstructive Sleep Apnea Patients Indicated for Surgery

You may qualify if:

  • Patients' age is more than 18 years old.
  • Patients are indicated for upper respiratory airway surgery based on adequate history taking, proper clinical examination, and sleep study.
  • Patients refusing Continuous Positive Airway Pressure (CPAP) treatment.
  • Systemically medically free patients.

You may not qualify if:

  • Patients who are refusing the surgical approach as a treatment plan option.
  • Patients who have undergone previous surgeries in the upper respiratory airway.
  • Pregnant women.
  • Patients who didn't follow post-operative instructions.
  • Patients who are not able to come for the follow-up appointments.
