Chest radiograph of the face and profile. Supraclavicular subcutaneous emphysema (green arrow) and pneumomediastinum (red arrows; retrosternal radiolucency following the contour of the heart and aorta) are observed.

Chest radiography (front and side) revealed subcutaneous supraclavicular soft tissue emphysema and pneumomediastinum (Figure 1).
Cervicofacial computed tomography scan of the frontal and axial sections. Air is present in the extraction site of 48 (orange arrow) and in the submandibular (blue arrows), retropharyngeal (green arrow), parapharyngeal (yellow arrow), and masticatory spaces (red arrow).

A cervicothoracic computed tomography (CT) scan without contrast injection confirmed parietal pneumatosis of the masticatory, submandibular, parapharyngeal, and retropharyngeal spaces (Figure 2) of the supraclavicular soft tissues with pneumomediastinum but without pneumothorax or pneumoperitoneum.
Chest computed tomography scan of the frontal, sagittal, and axial sections. Air is present in the supraclavicular soft tissue (blue arrows), mediastinum (green arrows), and retropharyngeal space (red arrows). (a) Chest computed tomography scan, frontal section. (b) Chest computed tomography scan, sagittal section. (c) Chest computed tomography scan, axial section.

No tracheobronchial tree lesions were detected (Figure 3).
Cervicothoracic frontal slices obtained during the computed tomography scan. Subcutaneous supraclavicular soft tissue emphysema (green arrow) and pneumomediastinum (red arrow) from 2nd to the 5th day after extraction are reduced. (a) Cervicothoracic tomography scan, frontal slices, 2nd day after wisdom tooth extraction. (b) Cervicothoracic tomography scan, frontal slices, 5nd day after wisdom tooth extraction.

A follow-up CT scan and physical examination after 2 days of hospitalization showed a clear decrease in emphysema and pneumomediastinum (Figure 4).
