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.
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. In some cases, the concha bullosa may be resected to help resolve persistent symptoms.
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]
Cold vs. sinus infection: What are the symptoms? A sinus infection typically starts out with a viral infection (RSV or rhinovirus, for example), which can cause sneezing, coughing, a runny nose ...
Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever. [6] [7] Sinusitis is a condition that affects both children and adults.
A CT scan showing evidence of the nasal cycle: the more patent airway is on the right of the image, the swollen turbinates congesting the left. The nasal cycle is the subconscious [1] [2] alternating partial congestion and decongestion of the nasal cavities in humans and other animals.
When Christine Spadafor started to experience frightening symptoms, doctors dismissed her concerns. She was finally diagnosed with an egg-size brain tumor. Woman's symptoms were dismissed as sinus ...
Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. [10] It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.
