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.
As Steven M. Houser suggested, "this is especially true in cases of anterior inferior turbinate (IT) resection because of its important role in the internal nasal valve." [9] 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 ...
The middle turbinates insert anteriorly into the frontal process of the maxilla and posteriorly into the perpendicular plate of the palatine bone. [1] There are three mutually perpendicular segments of the middle turbinate: from proximal to distal, there is the horizontal segment ( axial plane ), the basal lamella ( coronal plane ), and the ...
The basal lamella is continuous medially with the bony middle nasal concha. [7] Anteriorly, it vertically inserts into the ethmoid crest ; the middle part attaches obliquely into the orbital lamina of ethmoid bone (lamina papyricea) while the posterior part attaches into the orbital lamina horizontally.
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]
ENS-IT: Inferior turbinate (IT) was fully or partially resected; ENS-MT: Middle turbinate (MT) was fully or partially resected; ENS-both: Both the IT and MT were both at least partially resected; ENS-type: Patient appears to have adequate turbinate tissue but suffers ENS symptoms due to damage to the mucosal surface of the turbinates.
The supreme nasal concha or highest nasal concha is a nasal concha (turbinate) that occurs in some cases. It is shaped like a seashell and found on the posterosuperior part of the lateral nasal wall. [2] It lies on the medial surface of the labyrinth of ethmoid above the superior nasal concha.
