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. Occasionally, a large concha bullosa may cause it to bulge sufficiently to obstruct the opening of an adjacent sinus, possibly leading to recurrent sinusitis[1] and various head pains related to areas innervated by the trigeminal nerve.[2] In such a case the turbinate can be reduced in size by endoscopic nasal surgery (turbinectomy). The presence of a concha bullosa is often associated with deviation of the nasal septum toward the opposite side of the nasal cavity.[3]

One review of the septal surgery shows that significant relief of pain occurs in 65%-85% of surgeries. Screening of patients can cover presence of headache and facial pain and disability.[2]

Some experts call pain associated with enlarged concha bullosa "rhinogenic contact point headache."[4] In a review article of fifteen other journal articles of surgeries, significant improvements occurred after surgical treatment with a reduction from 88 (73%) to 6 (5%) patients for GRADE 3–4 MIDAS scores,[5] and a corresponding increase in milder symptoms from GRADE 1–2 in 32 (27%) patients at 91 (76%) (p < 0.001).
