In this study, the authors compared the right and left olfactory bulb volumes by magnetic resonance image findings of patients with unilateral concha bullosa (CB).
The cranial magnetic resonance imaging studies of 24 patients having unilateral CB were reviewed. There were 10 males and 14 females ranging in age from 29 to 51 years (mean age, 29 ± 15.2 years). The volumes of both olfactory bulbs (contralateral and ipsilateral to the concha bullosa side) were calculated by using the computer program.
The average values for olfactory bulb volumes were 46.57 ± 8.03 mm in the CB side of the nasal cavity and 54.80 ± 10.031 mm in the normal side of the nasal cavity. We found a statistically significant difference in olfactory bulb volume between the contralateral and ipsilateral to the concha bullosa side of the patients (t = -3.08 and P < 0.01 for CB side, t = -3.47 and P < 0.01 for left normal side).
Our results may point out a possible relationship between CB and ipsilateral decreased olfactory bulb volume, yet the exact mechanism still remains unclear. Decreased nasal air flow on the CB side may be attributed to the pathophysiologic mechanism of this finding. Also, the significant reduction in olfactory bulb volumes ipsilateral to CB compared with the contralateral olfactory bulb volumes seems to support our hypothesis.
在本研究中，作者通过单侧泡状鼻甲（CB）患者的磁共振成像结果比较左右嗅球体积。
回顾了24例单侧CB患者的头颅磁共振成像研究。其中男性10例，女性14例，年龄范围为29至51岁（平均年龄29±15.2岁）。使用计算机程序计算双侧嗅球（泡状鼻甲侧的对侧和同侧）的体积。
鼻腔CB侧嗅球体积的平均值为46.57±8.03mm，鼻腔正常侧为54.80±10.031mm。我们发现患者泡状鼻甲侧的对侧和同侧嗅球体积存在统计学显著差异（CB侧t = -3.08，P <0.01；左侧正常侧t = -3.47，P <0.01）。
我们的结果可能指出CB与同侧嗅球体积减小之间可能存在的关系，但确切机制仍不清楚。CB侧鼻气流减少可能归因于这一发现的病理生理机制。此外，与对侧嗅球体积相比，CB同侧嗅球体积的显著减少似乎支持了我们的假设。
