“…[4][5][6][7][8][9][10] Lacrimal gland cysts in pediatric patients require heightened attention because of the risk of mechanical ptosis, astigmatism, diplopia, and ocular dystopia, which may lead to enduring amblyopia 1,3 Although the exact etiology of dacryops remains unknown, several predisposing factors have been proposed including periductal or chronic conjunctival inflammation, trauma, chemical injury, or ocular trachoma infection. 1,[11][12][13][14][15] Herein, the authors report a 6-year-old male patient presenting with progressive left upper…”

: This report describes the spontaneous extrusion from between the eyelids of a presumed conjunctivolith in a patient with resolving severe herpes zoster ophthalmicus. A 57-year-old man presented for ophthalmologic assessment and management due to severe left herpes zoster ophthalmicus. At one subsequent ophthalmologic assessment, a conjunctivolith spontaneously egressed the lateral commissure of the OS when the lateral fornix was inspected. The conjunctivolith was retrieved from the floor of the consulting room. Electron microscopic analysis and energy dispersive spectroscopy was undertaken to determine its composition. Scanning electron microscopy showed that the conjunctivolith was composed of carbon, calcium, and oxygen. Transmission electron microscopy diagnosed Herpes virus within the conjunctivolith. Conjunctivoliths, or possible lacrimal gland stones, are a very rare phenomenon, and their etiology is currently unclear. In this case, there was likely to have been an association between herpes zoster ophthalmicus and the conjunctivolith.

“…The SS may show varying degrees and directions of pneumatization, with its various extensions bringing it in close relationship with the optic nerve, cavernous sinus, internal carotid artery, and other vital structures. [10][11][12][13][14][15] Pneumatisation of the GWS is inadequately reviewed in the literature, first described by John Earwalker in 10.7% of patients and since then several case series have been reported. 16 Wang et al gave a detailed description of the lateral extensions of the SS pneumatization into the GWS and the pterygoid process and the pterygoid process.…”

The goal of orbital decompression for thyroid orbitopathy is to expand the orbital space for the contents with various techniques described. Deep lateral wall decompression is a procedure that expands the orbit by removing bone from the greater wing of sphenoid however its effectiveness is dependent on the volume of bone removed. Pneumatization of the greater wing of sphenoid is defined as an extension of the sinus beyond the VR line (a straight line crossing the medial edges of the vidian canal and the foramen rotundum) which is a demarcation between the sphenoid body and the lateral parts of the sphenoid bone, including the greater wings and pterygoid process. We present a case of complete pneumatization of the greater wing of sphenoid affording a greater volume of bony decompression in a patient with significant proptosis and globe subluxation as a result of thyroid eye disease.

“…It is different from a pure anterior recess within the SR, thus an “anterior median recess” of the pre-sphenoid, such as we found here. Such median anterior recesses of the sphenoidal sinuses could be observed in figures in different publications, but they were neither discussed, nor classified [ 32 , 33 , 34 , 35 ].…”

The osseous nasal septum (NS) consists of the perpendicular plate of the ethmoid bone (PPE) and the vomer bone. Few studies evaluated the possibilities of septal pneumatization of the PPE, or adjacent to it. We aimed to observe the anatomical possibilities of NS pneumatizations. A retrospective lot of cone-beam computed tomography (CBCT) files was used. One hundred seventy-one CBCT files from 51 males and 120 females were documented. There were found 46 files that were null for septal pneumatization. The other cases (73.1%) had different septal pneumatizations extended from neighboring air spaces. Pneumatized crista galli (CG) exclusively extended from a frontal sinus was found in 7.01% of cases. The frontal sinuses had minor extensions anterior to the PPE in 7.6% of cases. Unique or double pneumatizations of the sphenoidal rostrum extending within the posterior part of the PPE were detected in 71.34% of cases. In six cases were found ethmoidal pneumatizations of the PPE, either from an anterior ethmoid cell, or from a posterior one, or from a pneumatized CG. In this last case was found a sinus septi nasi of 25.37 mm sagittal size. The supra-septal recesses of the ethmoid air cells were roofing the respective nasal fossa. As all the morphological possibilities of NS pneumatization involve the upper part of the PPE, they should be adequately discriminated anatomically, as well as when the NS and the cribriform plate of the ethmoid bone are approached surgically.
