Abstract

fetched live from OpenAlex

Introduction: Pneumo-orbit and periorbital subcutaneous emphysema secondary to defects in the sinus wall have been well described in the context of traumatic or surgical sequelae. However, these conditions may rarely occur atraumatically in the setting of an idiopathic or congenital sinus wall dehiscence, with a risk for orbital compartment syndrome and irreversible vision loss. We describe a case of idiopathic lamina papyracea dehiscence with resultant pneumo-orbit and elevated intraocular pressure. Case Presentation: A 28-year-old man experienced a sudden onset of unilateral orbital and subcutaneous periorbital emphysema following Valsalva maneuver. He had unilateral subcutaneous emphysema, crepitus, violaceous discoloration of the lids, and chemosis of the palpebral conjunctiva. Visual acuity was intact, and intraocular pressure was mildly elevated. Imaging showed an idiopathic lamina papyracea dehiscence. The patient was advised of sinus precautions with uneventful spontaneous resolution and no visual sequelae. Conclusion: Lamina papyracea dehiscence predisposes to spontaneous Valsalva-induced orbital or periorbital emphysema with a risk of elevated intraocular pressure, optic neuropathy, and vision loss; prompt recognition and early management can prevent vision-threatening sequelae.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
