Summary
An uncommon sinus condition, orbital pneumatocele, can cause proptosis and diplopia. Endoscopic sinus surgery effectively treated this condition in a patient, resolving the proptosis.
Area of Science:
- Otolaryngology
- Ophthalmology
- Neurosurgery
Background:
- Proptosis, or bulging of the eye, can arise from various orbital pathologies.
- Sinus conditions are rarely implicated as a direct cause of proptosis.
Observation:
- A 29-year-old male presented with intermittent unilateral proptosis and diplopia.
- Computed tomography revealed an enlarged frontal sinus with orbital floor erosion and air within the orbit.
Findings:
- Surgical correction of a nasal frontal duct outlet check valve via endoscopic ethmoidectomy and frontal sinusotomy.
- Complete resolution of proptosis following the endoscopic sinus surgery.
Implications:
- Orbital pneumatocele is an uncommon but treatable cause of proptosis and diplopia.
- Endoscopic sinus surgery offers a minimally invasive approach for managing orbital pneumatocele.
- This case highlights the importance of considering sinonasal abnormalities in the differential diagnosis of proptosis.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:13Pleura of the Lungs
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...
01:30Pneumonia I: Introduction
Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

01:26Pneumothorax-I
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

01:27Pneumothorax-II
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

01:08Pneumothorax II: Pathophysiology
Pneumothorax means the presence of air in the pleural space — the thin potential gap between the visceral and parietal pleura. This condition disrupts the normal pressure balance that keeps the lungs inflated, leading to partial or complete collapse of the affected lung.Normal physiologyUnder normal conditions, the pleural space maintains a slightly negative intrapleural pressure, which keeps the lungs expanded against the chest wall. This negative pressure creates a delicate balance between...
