Abstract
IntroductionAnatomic variations of the paranasal sinuses are very common. The paranasal sinus anatomy should be carefully examined prior to performing endoscopic sinus surgery in terms of both existent pathologies and anatomic variations. The anatomy of the paranasal sinuses and its variations have gained importance, along with advances in coronal paranasal sinus computed tomography and extensive use of endoscopic sinus surgery.Case presentationA 53-year-old Caucasian woman was admitted to our clinic with complaints of nasal breathing difficulties and headache persisting for a long time. Another concha bullosa was detected in the middle concha bullosa on preoperative paranasal computed tomography examination. It is known that the paranasal sinuses have a number of anatomical variations.ConclusionHerein we report a rare case, along with a review of the literature, to emphasize that a concha bullosa inside another concha bullosa should not be ignored.
Highlights
Anatomic variations of the paranasal sinuses are very common
An anterior rhinoscopy revealed an anatomy consistent with middle concha bullosa obstructing the bilateral nasal passages, and a septal deviation to the right side was observed. Her coronal paranasal sinus computed tomography (CT) scan revealed a giant middle concha bullosa and a large ethmoid bulla extending into the middle concha bullosa on the left side (Figures 1 and 2)
The anterior and posterior ethmoidal cells are considered responsible for the pneumatization of the middle concha in approximately 55% and 45% of concha bullosa cases, respectively [1,2]
Summary
The importance of the paranasal sinus anatomy and its variations has been emphasized, along with the extensive use of coronal paranasal sinus computed tomography (CT) and endoscopic sinus surgery (ESS). Case presentation A 53-year-old Caucasian woman was admitted to our clinic with the complaints of nasal breathing difficulties and headache of long duration She did not have a history of hospital admission or examination for these complaints. An anterior rhinoscopy revealed an anatomy consistent with middle concha bullosa obstructing the bilateral nasal passages, and a septal deviation to the right side was observed. Her coronal paranasal sinus CT scan revealed a giant middle concha bullosa and a large ethmoid bulla extending into the middle concha bullosa on the left side (Figures 1 and 2). The patient’s headache and nasal obstruction complaints were completely relieved within a short time after surgery
