A case of bilateral inferior concha bullosa connecting to maxillary sinus

A study on the association between the inferior nasal turbinate volume and the maxillary sinus mucosal lining using cone beam tomography

“…However, a study that measured the thickness of nasal turbinates in sinus volumes found that the sinus volumes decreased significantly with increasing turbinate thickness [ 36 ]. It is stated that the increase in turbinate size can lead to nasal obstruction and recurrent sinusitis [ 37 ]. This could be a possible reason for the increased volumes of the inferior turbinates in subjects with increased thickness of maxillary sinus mucosal lining.…”

Incidental Finding of Bullous Concha by Cone Beam Computed Tomography

“…Concha bullosa is defined as a partial or complete pneumatization of the turbinate (8), that tends to be asymptomatic, but in some cases may constitute a mass that impairs ventilation and mucus drainage of the ostiomeatal region, leading to sinusitis (1,9).…”

“…In this sense, the progress of modern imaging modalities, such as computed tomography (CT), makes possible a better treatment plan before nose/sinus surgery. CT provides accurate information and provides fine details of the patient's anatomy, revealing the presence of anatomical variations (1,9). Surgical approach of concha bullosa should carefully preserve the medial lamella and resect only the lateral half of the turbinate.…”

“…The nasal cavity is divided by a central septum in two lateral compartments, whose external walls are composed of the superior, middle and inferior conchae. The space beneath the nasal conchae represents a passage of the nasal cavity and is defined as meatus (1).…”

Características morfológicas e implicações clínicas e cirúrgicas da concha nasal suprema: uma revisão integrativa

“…Eventualmente, pode existir uma quarta concha (de Santorini) e, mais raramente, uma quinta concha (de Zuckerkandl), conhecidas como conchas nasais supremas. A concha nasal inferior é um osso separado, enquanto que as conchas nasais média, superior e suprema pertencem ao osso etmoide (Hiatt, 2011;Koo et al, 2018;Nieto, 2015;Rusu et al, 2019). Abaixo de cada concha nasal, há reentrâncias semelhantes a sulcosos meatos nasais superior, médio e inferior.…”
