Isolated sphenoid
Sphenoid bone
The sphenoid bone is an unpaired bone of the neurocranium. It is situated in the middle of the skull towards the front, in front of the temporal bone and the basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended.

What causes opacification of the paranasal sinus?
Sinonasal inflammatory disease with sinus ostial obstruction is a very common cause of an opacified paranasal sinus. An air-fluid level suggests acute sinusitis; in chronic sinus disease, one may see mucosal thickening and sclerosis of the bony sinus walls. 1 The sinus is normal in size. There are certain recurring patterns of inflammatory sinus disease that may be seen on sinus computed tomography (CT). 2 These include: the infundibular pattern, with inflammation of the maxillary sinus and opacification of the ipsilateral ostium and infundibulum; the ostiomeatal unit pattern, with inflammation of the ipsilateral maxillary, frontal and ethmoid sinuses and occlusion of the middle meatus (Figure 1); the sphenoethmoidal recess pattern, with obstruction of the sphenoethmoidal recess and inflammation of the ipsilateral posterior ethmoid and sphenoid sinuses; the sinonasal polyposis pattern, which is characterized by the diffuse presence of polyps in the paranasal sinuses and nasal cavity; and the sporadic pattern, also termed unclassifiable, which is diagnosed when there is random sinus disease not related to ostial obstruction or polyposis. The most commonly occurring patterns are the infundibular, ostiomeatal and sporadic. Knowledge and identification of these patterns may be helpful in surgical planning.
What is sinonasal polyposis?
Sinonasal polyposis. Sinonasal polyposis is a typically extensive process with involvement of both the nasal cavity and the paranasal sinuses. By contrast, mucous retention cysts are typically limited to the sinus cavity in location. CT findings of sinonasal polyposis include polypoid masses in the nasal cavity, ...
What is a mucocele?
By definition a completely opacified, nonenhancing and mucus-filled expanded sinus, a mucocele is the most common expansile mass of a paranasal sinus (Figure 3). Most often secondary to an obstruction of the sinus ostium, mucoceles may also result from surgery, osteoma or prior trauma; this is especially true of frontal sinus mucoceles. 10 The frontal sinuses are most frequently affected (60-65%), followed by the ethmoid (20-30%), maxillary (10%) and sphenoid (2-3%). 11 Sinus expansion may result in intracranial and intraorbital extension, with mass effect on adjacent structures. Mucoceles can also occur in isolated sinus cells. Optic neuropathy and acute visual loss caused by an isolated mucocele of an Onodi cell have been reported. 12 An Onodi (sphenoethmoid) cell is the most posterior ethmoid cell that pneumatizes laterally and superiorly to the sphenoid sinus and is intimately associated with the optic nerve (Figure 4). 13
What is a fungus ball?
Mycetoma. Mycetoma, also known as a “fungus ball,” is a manifestation of fungal sinus disease. Fungal sinusitis is broadly categorized as invasive or noninvasive, with five major subtypes. The noninvasive subtypes typically occur in immunocompetent individuals and include mycetoma and allergic fungal sinusitis.
Where do dentigerous cysts originate?
Dentigerous cyst. Both dentigerous cysts and ameloblastomas, which are discussed in greater detail in the next section, originate in the bony maxilla and may then secondarily involve the adjacent maxillary sinus. The dentigerous cyst is the most common type of a developmental odontogenic cyst.
What is a dentigerous cyst?
A dentigerous cyst that involves a paranasal sinus usually is related to a maxillary canine, with secondary extension into the antrum. 20. A dentigerous cyst arising in the bony maxilla outside of the antrum is, by definition, an extra-antral lesion.

Diagnosis
- Both silent sinus syndrome (SSS) and the mucocele, which is discussed in the next section, are characterized by abnormal sinus size, with reduced sinus volume in SSS and sinus expansion in mucocele. The term silent sinus syndrome is characterized by unilateral progressive painless enophthalmos, hypoglobus and facial asymmetry due to chronic maxillary sinus atelectasis.3 Th…
Treatment
- The definitive treatment is surgical with endoscopic uncinectomy and opening of the maxillary ostium.9 This will arrest disease progression; sinus volume typically stabilizes, although it may improve slightly or regain near normal configuration. Orbital floor repair may be helpful in cases with diplopia, severe cosmetic deformity or those with litt...

Structure
- Both dentigerous cysts and ameloblastomas, which are discussed in greater detail in the next section, originate in the bony maxilla and may then secondarily involve the adjacent maxillary sinus.
Clinical significance
- A dentigerous cyst arising in the bony maxilla outside of the antrum is, by definition, an extra-antral lesion. The demonstration of a thin bony plate representing the floor of the maxillary sinus between the cystic expansile mass and the adjacent maxillary sinus is critical in the identification of the extraantral nature of the lesion.21 On CT, a dentigerous cyst demonstrates an expanded u…
Prognosis
- Ameloblastoma is the most common odontogenic tumor. Defined as a benign epithelial neoplasm, the tumor is locally aggressive and invasive. Incomplete resection may result in local persistence or recurrence or, rarely, distant typically pulmonary metastases. Interestingly, approximately 50% of ameloblastomas arise from the lining of a dentigerous cyst.23 A unilocula…
Epidemiology
- Like dentigerous cysts, ameloblastomas occur much more commonly in the mandible than the maxilla; only 20% of ameloblastomas occur in the maxilla.22 The premolar-first molar location is common for a maxillary ameloblastoma. These maxillary tumors then easily expand into the ipsilateral antrum or the adjacent nasal cavity.
Appearance
- On CT, an ameloblastoma appears as an expansile cystic, solid or mixed attenuation lesion with scalloped margins. Thinning of the maxillary cortex is often extensive. The lesion may be uni- or multilocular and contain internal septations; the resultant honeycomb or bubbly appearance is typical but not pathognomonic. The solid regions may show contrast enhancement. (Figure 8). I…
Introduction
- In patients with known or suspected sinonasal polyposis, unenhanced sinus CT is the examination of choice. Enhanced CT or MRI may be helpful in select cases, such as distinguishing polypoid mucosal hypertrophy from sinus fluid, excluding an obstructing soft tissue neoplasm, and in cases with atypical CT findings and aggressive-looking bone destruction.27,33 Most sinonasal p…
