Medical Definition of sphenoethmoid recess
: a small space between the sphenoid bone and the superior nasal concha into which the sphenoid sinus opens.
What is the purpose of sphenoethmoidal recess?
The sphenoethmoidal recess drains the posterior ethmoid air cells and sphenoid sinuses into the superior meatus of the nasal cavity.
What is Sphenoethmoidal sinusitis?
Sphenoethmoidal recess pattern: inflammatory changes in the sphenoethmoidal recess obstruct the sphenoid sinus in isolation or in conjunction with the posterior ethmoidal air cells. Sinonasal polyposis pattern: extensive polyps are occupying the nasal cavity and the paranasal sinuses.
What is hiatus semilunaris?
The semilunar hiatus or hiatus semilunaris, is a crescent-shaped groove in the lateral wall of the nasal cavity just inferior to the ethmoid bulla. It is the location of the openings for maxillary sinus.
What is frontal recess?
The frontal recess is an opening in the inferior aspect of the frontal sinuses that allows drainage of the sinus.
What is basal lamella?
The basal lamella, also known as basal lamella of the middle turbinate, is an osseous lamella that separates the anterior from the posterior ethmoid sinuses 1.
What is Choanae?
Medical Definition of choana
: either of the pair of posterior apertures of the nasal cavity that open into the nasopharynx. — called also posterior naris.
What is mucosal thickening?
Mucosal thickening is an inflammatory reaction with hyperplasia of the mucous lining of the maxillary sinus. 2. This condition may result from harmful actions caused by trauma, infections, chemical agents, foreign body reaction, neoplasm, or airway conditions such as allergies, rhinitis, or asthma. 6.
What is right concha bullosa?
A concha bullosa is a pneumatized (air-filled) cavity within a nasal concha, also known as a turbinate. Bullosa refers to the air-filled cavity within the turbinate. It is a normal anatomic variant seen in up to half the population.
What causes sphenoid sinus disease?
Sphenoid sinusitis can be caused by both bacterial and viral infections that impact the upper respiratory system. Other possible factors include a weakened immune system, tooth abscesses, nasal polyps, nasal defects and enlarged adenoids.
How do you open a sphenoid sinus?
Sphenoid sinus can be opened with several techniques. The ostia can be directly approached. The sphenoid rostrum is approached between the middle and superior turbinate laterally and the septum medially. Unlike tumor surgery, resecting the inferior portion of the middle turbinate is usually not necessary.
What is the best treatment for sphenoid sinusitis?
In general, start medical treatment of acute sphenoid sinusitis once the diagnosis is made. Institute antibiotics and decongestants for 24 hours, and if the patient does not improve over this time course, schedule surgical therapy. If the patient has evidence of complications, undertake urgent surgical decompression.
How is fungal sinusitis treated?
Antifungal medications can be used as well, but usually not without a surgery. There have been some studies that indicate that antifungal medications called “azoles,” such as itraconazole, can be useful in treating allergic fungal sinusitis. With invasive fungal sinusitis, use of antifungal medications is required.
Is chronic sphenoid sinusitis serious?
Typically, patients with sphenoid sinus disease report a long clinical history and often present with retro-orbital headache. Chronic sphenoid sinusitis requires early diagnosis and should be appropriately treated because its regional complications can be devastating and potentially life-threatening.
