Maxillary sinusitis is common due to the close anatomic relation of the frontal sinus, anterior ethmoidal sinus and the maxillary teeth, allowing for easy spread of infection. Differential diagnosis of dental problems needs to be done due to the close proximity to the teeth since the pain from sinusitis can seem to be dentally related. [ 1 ]
The maxillary sinuses, the largest of the paranasal sinuses, are under the eyes, in the maxillary bones (open in the back of the semilunar hiatus of the nose). They are innervated by the maxillary nerve (CN V2). [2] The frontal sinuses, superior to the eyes, in the frontal bone, which forms the hard part of the forehead.
Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever. [6] [7] Sinusitis is a condition that affects both children and adults.
Age: Below the age of 3 years, as the size of the sinus is small due to underdeveloped Maxillary Sinus. [10] Bleeding disorders: May lead to epistaxis. [10] Fracture of maxilla: Antral Lavage may result in escape of the fluid through fracture lines. [10] Febrile stage of acute maxillary sinusitis: May cause osteomyelitis of Maxilla. [10]
The ethmoid sinuses or ethmoid air cells of the ethmoid bone are one of the four paired paranasal sinuses. [1] Unlike the other three pairs of paranasal sinuses which consist of one or two large cavities, the ethmoidal sinuses entail a number of small air-filled cavities ("air cells"). [ 2 ]
There are two primary types of nasal polyps: ethmoidal and antrochoanal. Ethmoidal polyps arise from the ethmoid sinuses and extend through the middle meatus into the nasal cavity. Antrochoanal polyps usually arise in the maxillary sinus and extend into the nasopharynx and represent only 4–6% of all nasal polyps. [7]
Silent sinus syndrome is a subtype of stage three chronic maxillary atelectasis. The distinguishing factor is that in silent sinus syndrome, there is an absence of sinusitis symptoms. [3] [4] [5] To be clear, chronic maxillary sinusitis may be a primary causitive factor in a significant number of silent sinus syndrome cases, it just may be ...
Ethmoid sinus cavities which are located between the eyes. Frontal sinus cavities which can be found above the eyes (more in the forehead region). Maxillary sinus cavities are located on either side of the nostrils (cheekbone areas). Sphenoid sinuses that are located behind the eyes and lie in the deeper recesses of the skull.
