RADIATION EXPOSURE IN DAILY LIFE
Average annual effective dose in the US is 3,000 µSv*
This is approximately 8 µSv/day

AirwayAnalysis
AIRWAY: -The soft palate was approximately 48 mm long. - Nasal septum deviation and small concha bullosa of the right and left middle nasal turbinates was noted. -The most constricted area of the airways corresponded to the area posterior to the tongue and soft palate and it is reduced (approximately 70 mm2). This space is small and should be considered an intermediate risk factor for obstructive sleep apnea (OSA).

Sinus Evaluation
Signs of increase in the mucosal thickening were noted from the floor of the maxillary sinuses and from selected ethmoidal air cells. This is consistent with allergies or another condition of inflammatory origin (sinusitis). The antromeatal complexes were patent/clear. - Dome-shaped soft tissue densities were noted from the floor of the maxillary sinuses and sphenoid sinus. They are consistent with mucous retention cysts/sinus polyposis. - A soft tissue density was noted from the superior-anterior wall of the left maxillary sinus. This is consistent with a sinus polyp.

TMJ Evaluation
Left
Evidence of mild sclerosis and flattening for the superior/posterior surface of the left condyle and sclerosis for the posterior slope of the left eminence was noted.

TMJ Evaluation
Right
The right condyle was small. The reduction in size occurred along the posterior and superior surface of the right condyle (anterior-posterior and vertical dimension). Evidence of sclerosis, flattening and small osteophyte formation for the superior/anterior surface of the right condyle and mild sclerosis for the posterior slope of the right eminence was noted.

TMJ Evaluation
Position: When the mandible was in “closed” position the right condyle was positioned posterior to the center and the left condyle close to the center of their respective fossa. The right posterior articular spaces were reduced.
OTHERS: - Bilateral elongation/partial calcification was noted for the styloid-hyoid ligament/process.

The findings described above should be considered risk factors for obstructive sleep apnea (OSA).

Radiologist Impressions
TMJs
The findings described above are most consistent with NON-ACTIVE degenerative joint disease (DJD) for the right TMJ and osseous remodeling for the left TMJ. DJD involves the destruction of the articular tissues and may occur when the remodeling capacity of those tissues has been exceeded by the functional demands. The presence of these changes increases the probability of a displaced disc in the right TMJs. Reduction of condylar size maybe associated with changes in occlusion, asymmetries and mandibular posture which may predispose to TMJ dysfunction.The posterior positioned condyles within their fossa may predispose to anterior displaced discs and compression of the posterior surface of the condyles and the adjacent retrodiscal tissues.

Radiologist Impressions
Most of the other findings and their correspondent diagnosis were noted above. Please correlate the sections with the axial and panoramic views for additional diagnosis and treatment planning purposes. Reviewing the remaining available volume, there was no evidence of any other anomaly/pathology in the maxillofacial and surrounding structures available in this study.

So what did we learn?
Patient has small airway and is at risk for OSA
Nasal airway is compromised. Pt. may have allergies and has sinus abnormalities.
TMJ’s have existing abnormalities.
Teeth are adequate support for Dental Sleep Therapy (DST).

Advise patient they are at risk for OSA.
Advise patient they have increased risks of problems with CPAP and/or Dental Sleep Therapy (DST) due to nasal problems.Advise patient should consider ENT and/or allergist
referral.
Advise patient they have existing TMJ concerns and they are at higher risks of complications with DST.
