Large Concha Bullosa Mucopyocele Replacing the Anterior Ethmoid Sinuses and Contiguous with the Frontal Sinus

Abstract: Concha bullosa, a pneumatized middle turbinate, is a common anatomic variant found in the paranasal sinuses. When a concha bullosa becomes obstructed, it can form a mucocele and, eventually, a mucopyocele if it becomes secondarily infected. This is a rare phenomenon; only 9 concha bullosa mucopyoceles have been previously reported in the English-language literature. We present the case of a large concha bullosa mucopyocele in a pediatric patient in which the concha bullosa replaced the anterior ethmoid sinuses… Show more

“…Bolger et al (5) classifies CB pneumatization according to its location; when it involves the vertical lamella it is referred to as lamellar, whereas involvement of the inferior bulbous segment is referred to as bulbous. When pneumatization involves the entire concha it is referred to as extensive; if it obstructs the sinus ostia nasal obstruction or headache can occur (6). In our patient, nasal obstruction was the main symptom.…”

“…Mucoceles and mucopy-oceles are uncommon in the CB, with only 10 previous reports of CB mucoceles or mucopyoceles (3,(6)(7)(8). Mucoceles of the paranasal sinuses or CB typically develop due to an obstruction in the mucociliary transport system.…”

“…A mucocele or mucopyocele can cause local bone erosion, diplopia, and nasal obstruction. 3 The incidence of concha bullosa varies from 14% to 53%. Pneumatization of the middle turbinate was categorized according to its location into 3 types: when involving the vertical lamella of the concha, it is termed as ''lamellar''; the inferior bulbous segment of the concha as ''bullous''; and the entire concha (both the lamellar and bullous portions) as ''true concha bullosa.''…”

“…2 The middle turbinate is a bone plate located inferomedially to the ethmoid air cells, and a concha bullosa, the most common variant in the sinonasal anatomy, is an extension of these anterior ethmoid air cells. 3 It is lined with the same mucous membrane and possesses the same mucociliary transport system present in the paranasal sinuses, as well as an ostium connecting it to the frontal recess. 4 Therefore, obstruction of the ostium can lead to the development of a mucocele or mucopyocele.…”
