Surgeons have, for many years, suspected that a pneumatized middle turbinate (choncha bullosa) is associated with an increased incidence of sinonasal disease. At the spring meeting of the American Rhinologic Society in Palm Springs, Fla, Steve Clark, MD, and his colleagues at the University of Tennessee, Memphis, reported their use of computed tomographic scans to study the incidence of choncha bullosa. They evaluated two groups of patients, one group (82 patients) with symptoms of rhinosinusitis and another group of patients, composed mostly of trauma victims, without a history of sinonasal disease. They reported the prevalence of choncha bullosa to be 33% in the rhinosinusitis group, compared with 11% in the trauma group. In the emerging era of "functional" endoscopic sinus surgery, it will be important to know the significance of a choncha bullosa. Whether it causes nasal and sinus inflammation is still unknown, but the increased association of choncha bullosa
