Objective: The aim of this study was to retrospectively evaluate the incidence of posttraumatic orbital emphysema (OE) and to propose a radiologic topographic classification as well as a possible pathophysiologic model.
Study Design: Orbital fine-cut (1 mm) computerized tomographic scan slices from 137 patients were used to assess the fracture's type, the presence and position of OE, and periorbital tissue herniation. The OE was categorized into the following 5 compartments: subcutaneous periorbital, peribulbar, retrobulbar extra- and intraconal, and pterygopalatine fossa.
Results: The incidence of OE was 61%. OE was more frequently associated with isolated medial wall (78%; P < .001) and combined medial wall/orbital floor (82%; P < .01) fractures. Palpable isolated subcutaneous eyelid emphysema was not related to fracture's type (P = .85).
Conclusions: OE suggested medial wall fractures alone or combined with orbital floor fractures. Pathophysiologically, according to the Poiseuille law, the difference in length between the ethmoid and sinusal infundibulii could explain the increased incidence of OE when the medial wall is involved.

Selective resection of the medial wall of the cavernous sinus in pituitary surgery: results of a prospective single center analysis.
Pituitary

Department of Neurosurgery, Mayo Clinic, Jacksonville, FL, USA.
Purpose: Pituitary adenomas, despite their histologically benign nature, can severely impact patients' quality of life due to hormone hypersecretion. Invasion of the medial wall of the cavernous sinus (MWCS) by these tumors complicates surgical outcomes, lowering biochemical remission rates and increasing recurrence. This study aims to share our institutional experience with the selective resection of the MWCS in endoscopic pituitary surgery.

Aortic arch anomalies represent a range of congenital vascular malformations resulting from disruptions in the typical embryological development of the aortic arch and its branches. These anomalies, which vary widely in their presentation, can lead to significant clinical symptoms depending on their structure and position. We report the case of a 75-year-old male with intermittent hypertension, palpitations, and episodic warmth in the upper body.

Thoracic aortic aneurysms are considered more dangerous than abdominal aneurysms because they are often silent until rupture and, therefore, are more challenging to diagnose and have a high mortality rate. In addition, a thoracic aneurysm differs from an abdominal one in terms of causes and risk factors: the former is associated with the degeneration of the vessel's middle tunica, while the latter is related to atherosclerosis. We report the case of the sudden death of a 20-year-old man, with no apparent risk factors and suffering only from a persistent cough for a month, in whom the autopsy revealed the rupture of a massive aneurysm of the ascending thoracic aorta.

: Canine tooth syndrome is a rare condition defined by the simultaneous presence of superior oblique palsy and Brown syndrome, resulting from pathological changes in the trochlear region. This syndrome can develop through various mechanisms, including dog bites, head trauma, infections, inflammation, and scarring. This report highlights its occurrence following sinus surgery for the first time.
