OBJECTIVE: To analysis the relationship between nasal septal deviation and the bulbous type concha bullosa(CB). METHOD: Analysis the paranasal sinus coronal plane CT scans of 972 patients,observe the incidence of nasal septal deviation and bulbous type concha bullosa and classify them into upper septal deviation and lower septal deviation. Measure the septal deviation angle and transverse diameter of the bulbous type concha bullosa, and a nalysis the relationship between nasal septal deviation and the bulbous type concha bullosa. RESULT: The incidences of bulbous type concha bullosa was 17.03% of 182 patients with nasal septal deviation and was 14.05% of 790 patients without nasal septal deviation. There was no statistically difference between them(P > 0.05). The incidences of bulbous type concha bullosa were 33.33% and 9.02% of the patients with upper septal deviation and lower septal deviation, and the difference was statistical (P < 0.01). The mean of the septal deviation angle was 14.55 degrees +/- 3.61 degrees, and the transverse diameter of the bulbous type concha bullosa was (5.93 +/- 1.88) mm in 20 patients with upper septal deviation and CB. The mean of the septal deviation angle was 13.36 degrees +/- 2.42 degrees, and the transverse diameter of the bulbous type concha bullosa was (4.86 +/- 1.40) mm in 11 patients with lower septal deviation and CB. There was no statistically difference between the septal deviation angle and the transverse diameter of bulbous type concha bullosa (P > 0.05). CONCLUSION There was a significant relationship between upper nasal septal devia tion and bulbous type concha bullosa, especially finding bulbous type concha bullosa in concave sides of nasal sep turn. But there was no significant relationship between the septal deviation angle and the size of the bulbous type concha bullosa.

OBJECTIVE: To retrospectively analyze the clinical characteristics of the benign paroxysmal positional vertigo (BPPV) secondary to the sudden deafness (SD) and to explore pathogenetic mechanism. METHOD: One hundred and seventy-eight cases of the SD in our department were retrospectively analyzed. They were all treated under the guidance of clinical guidelines. RESULT: (1) In all these patient's with SD, there were 31 cases with BPPV secondary to the SD. There were 26 cases of BPPV of posterior semicircular canal and 5 cases of BPPV of lateral BPPV semicircular canal. All patients with BPPV were diagnosed as the same ears as the SD, including 16 cases on left sides and 15 on right sides. (2) The interval between the onset of SD and BPPV was less than one week in 27 cases, between one week and one month in 3 cases, and between one and three months in 1 case. (3) All patients with BPPV secondary to the SD were cured with Epley maneuver or Barbecue roll maneuver. CONCLUSION The occurrence of BPPV may follow SD, and the major of BPPV secondary to the SD occurs in the posterior semicircular canal. The canalith repositioning is an effective therapy to the secondary BPPV.
