We investigated the incidence and the clinical impact of these variations. Twenty\u2010eight patients, 19 males and 9 females with a mean age of 41.5 years, representing different ethnic origins, were diagnosed with double middle turbinates based on endoscopic examination. Of those, 92.8% had a main symptom of refractory frontal headache. A secondary nasal symptom was sensation of blocked nose. Patients who underwent endoscopic surgery (<jats:italic>n<\/jats:italic> = 13) for reduction of the extra turbinate, reported significant symptom scores improvement (<jats:italic>P<\/jats:italic> &lt; 0.0001) of frontal headache and blocked nose, from means of 9.07 \u00b1 0.26 and 8.57 \u00b1 1.39 to 1 \u00b1 0.31, and 1.42 \u00b1 0.35, respectively. Our results indicate that double middle turbinates may be encountered in rhinology practice (2%). Clinically they may present with refractory headache and blocked nose. Endoscopic surgical approach seems to be an effective way of improving the symptoms. Clin.
