Abstract
Inferior concha bullosa is a rare disease that has been related to sinonasal symptoms. This study aimed to determine the characteristics of concha bullosa in the inferior turbinate and assess its common clinical manifestations, computed tomography findings, and the surgical techniques used to treat the condition.We conducted a search of the PubMed database, using the Preferred Reporting Items of Systematic Reviews and Meta-Analysis, for articles published until May 2021 using the following terms: “inferior turbinate and concha bullosa”; “inferior turbinate and pneumatization”; and in combination with other terms such as “concha bullosa release and concha bullosa excision”, among others.We found 12 papers that met our inclusion criteria. The main presenting symptom was a nasal obstruction in 13 patients (100%), followed by headache in 10 patients (77%). The site of inferior concha bullosa was bilateral in six cases and left-sided in five cases. Computed tomography was conducted in all cases in this review. The type of intervention performed was medical, surgical, and both in 23%, 54%, and 23% of the cases.Despite multimodal surgical approaches and medical treatment, all the outcomes were good and no compactions were noted. All cases also had good prognoses.
Highlights
BackgroundSinonasal disease is one of the diseases frequently encountered in primary care and otorhinolaryngology clinics
A radiological study assessed 594 computed tomography (CT) scans that revealed the incidence of middle turbinate concha bullosa (CB) at 53.7% compared to only 1% (6/594) for the inferior turbinate CB, which were mostly unilateral cases [4]
We included case reports in this review, wherein a total of patients were diagnosed with inferior turbinate CB through history assessment, physical examination, and imaging (Table 1)
Summary
BackgroundSinonasal disease is one of the diseases frequently encountered in primary care and otorhinolaryngology clinics. A pneumatized turbinate is termed concha bullosa (CB), which refers to the presence of an air cell within a nasal turbinate [1]. It is one of the most common sinonasal anatomic variations. Concha bullosa occurs rarely in the inferior turbinate. It is more common in the middle turbinate, followed by the superior turbinate [1]. A radiological study assessed 594 CT scans that revealed the incidence of middle turbinate CB at 53.7% compared to only 1% (6/594) for the inferior turbinate CB, which were mostly unilateral cases [4]. Another study reported that most of the pneumatization was unilateral in 14 (88%) patients and bilateral in two (12%) patients [1]
