Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. [citation needed]
On an x-ray, cysts appear as radiolucent (dark) areas with radiopaque (white) borders. [7] However, cysts in maxillary sinus, also known as antrum, can appear radiopaque as the surrounding air absorbs fewer photons than the cystic fluid content. Cysts are usually unilocular, but may also be multilocular.
Maxillary sinusitis is inflammation of the maxillary sinuses. The symptoms of sinusitis are headache, usually near the involved sinus, and foul-smelling nasal or pharyngeal discharge, possibly with some systemic signs of infection such as fever and weakness.
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.
Odontogenic sinusitis. Odontogenic sinusitis is a type of sinusitis (inflammation of the sinuses), specifically caused by dental infections or procedures. [1] Comprising approximately 10-12% of all chronic sinusitis cases, this condition primarily affects the maxillary sinus, which is in close proximity to the upper teeth. [2]
Classic symptoms of sinus disease such as headache, facial pain, purulent nasal discharge or nasolacrimal obstruction [12] may occur when maxillary sinus is involved. According to a study, 45.7 percent of dentigerous cysts involved mandibular third molar. [8] On the other hand, only 2.7 percent of dentigerous cysts involved the maxillary premolar.
Paranasal sinuses: 1. frontal sinuses, 2. ethmoid sinuses (ethmoidal air cells), 3. sphenoid sinuses, 4. maxillary sinuses The exact cause of nasal polyps is unclear. [ 1 ] They are, however, commonly associated with conditions that cause long term inflammation of the sinuses. [ 8 ]
The nasopalatine duct cyst (NPDC) occurs in the median of the palate, usually anterior to first molars. It often appears between the roots of the maxillary central incisors. Radiographically, it may often appear as a heart-shaped radiolucency. It is usually asymptomatic, but may sometimes produce an elevation in the anterior portion of the palate.
