Mucous retention cyst in maxillary sinus indicated by the asymmetrical blue lump to the right of the nose The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa ), on the anterior ventral tongue , and the floor of the mouth .
The sphenoid sinus is a paired paranasal sinus in the body of the sphenoid bone. It is one pair of the four paired paranasal sinuses. [1] The two sphenoid sinuses are separated from each other by a septum. Each sphenoid sinus communicates with the nasal cavity via the opening of sphenoidal sinus.
Nasopharyngeal cyst refers to cystic swelling arising from midline and lateral wall of the nasopharynx. The commonest cyst arising from lateral wall is the nasopharyngeal branchial cyst, whereas the mucus retention cysts are the commonest to arise from the midline. [1] Sometimes nasopharyngeal cyst may directly refer to Tornwaldt cyst. [2]
Oral mucocele is the most common benign lesion of the salivary glands generally conceded to be of traumatic origin. It is characterized by the pooling of mucus in a cavity due to the rupture of salivary ducts or acini.
For example, mucous cyst of the oral mucosa and nasolabial duct cyst are not of odontogenic origin. In addition, there are several conditions with so-called ( radiographic ) ' pseudocystic appearance' in jaws; ranging from anatomic variants such as Stafne static bone cyst , to the aggressive aneurysmal bone cyst .
Paranasal sinuses are a group of four paired air-filled spaces that surround the nasal cavity. [1] The maxillary sinuses are located under the eyes; the frontal sinuses are above the eyes; the ethmoidal sinuses are between the eyes and the sphenoidal sinuses are behind the eyes.
Polyps arise from the lining of the sinuses. Nasal mucosa, particularly in the region of middle meatus becomes swollen due to collection of extracellular fluid. This extracellular fluid collection causes polyp formation and protrusion into the nasal cavity or sinuses. Polyps which are sessile in the beginning become pedunculated due to gravity ...
This treatment has shown good results in aviators who have recurrent sinus barotrauma. Computer-aided surgery has re-established the drainage of affected sinuses, especially with regard to the sphenoid sinuses. [10] When the sphenoids were entered endoscopically, mucosal petechia and hematoma were clearly seen.
