Concha bullosa on both sides (marked with asterisks), coronal orientated image from CT. A concha bullosa is a pneumatized (air-filled) cavity within a nasal concha, also known as a turbinate. [1] Bullosa refers to the air-filled cavity within the turbinate. [1] It is a normal anatomic variant seen in up to half the population.
Concha bullosa is an abnormal pneumatization of the middle turbinate, which may interfere with normal ventilation of the sinus ostia and can result in recurrent sinusitis. In some cases, the concha bullosa may be resected to help resolve persistent symptoms.
A common anatomic variant is an air-filled cavity within a concha known as a concha bullosa. [77] In rare cases a polyp can form inside a bullosa. [78] Usually a concha bullosa is small and without symptoms but when large can cause obstruction to sinus drainage. [79]
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.
Medication temporarily relieves symptoms, but does not correct the underlying condition. Non-medical relief can also be obtained using nasal strips. A minor surgical procedure known as septoplasty can cure symptoms related to septal deviations. The surgery lasts roughly one hour and does not result in any cosmetic alteration or external scars.
The semilunar hiatus (eg, hiatus semilunaris) is a crescent-shaped [citation needed] /semicircular/ [1] curved [2] slit [2] /groove [1] upon the lateral wall of the nasal cavity [3] at the middle nasal meatus just inferior to the ethmoidal bulla. [2]
The ethmoid bulla (or ethmoidal bulla) is a rounded elevation upon the lateral wall of the middle nasal meatus [1] [2]: 377 (nasal cavity inferior to the middle nasal concha) produced by one or more of the underlying middle ethmoidal air cells (which open into the nasal cavity upon or superior to the ethmoidal bulla [2]: 374 [3]).
Bullous keratopathy, also known as pseudophakic bullous keratopathy (PBK), is a pathological condition in which small vesicles, or bullae, are formed in the cornea due to endothelial dysfunction.
