Abstract

Background: Nasal airway stenosis may lie anterior and/or posterior to the piriform aperture. We intended to compare the nasal airway anterior and posterior to the piriform aperture in patients with and without nasal obstruction.

Methods: Segmented computed tomography cross-sectional areas of the nasal airway anterior (CT-CSA_ant) and posterior to the piriform aperture (at the level of the head of the inferior turbinate; CT-CSA_post) were compared between patients with nasal obstruction (cases) and trauma controls. CT-CSA were approximately perpendicular to the direction of the nasal airflow. Anterior to the piriform aperture, they were tilted about 30^o, 60^o and 90^o to the nasal floor. Posterior to the piriform aperture, they were tilted about 50^o, 80^o and 100^o to the nasal floor. In cases, we examined the Pearson's correlation of active anterior rhinomanometry with CT-CSA_ant and CT-CSA_post.

Results: Narrow and bilateral CT-CSA_post were similarly large between 56 cases and 56 controls (all p > 0.2). On the contrary, narrow and bilateral CT-CSA_ant were significantly smaller in cases than in controls (all p < 0.001). The ratio of the size of CT-CSA_ant-30 to that of CT-CSA_post-80 was significantly lower in cases (median: 0.84; lower to upper quartile: 0.55-1.13) than in controls (1.0; 0.88-1.16; Mann-Whitney U test; p = 0.006). Bilateral CT-CSA_ant correlated significantly with total inspiratory flow (all p < 0.026) in contrast to bilateral CT-CSA_post (all p > 0.056).

Conclusions: The nasal airway anterior to the piriform aperture was smaller in patients with nasal obstruction due to skeletal nasal stenosis than that in controls. On the contrary, the nasal airway posterior to the piriform aperture was similarly large between patients with and without nasal obstruction. Furthermore, in patients with nasal obstruction, the anterior nasal airway was narrower compared to that located posterior to it. On the contrary, control patients' anterior nasal airway was as large as the posterior one.

鼻阻塞和无鼻阻塞患者蝶形孔前后鼻腔气道的 CT 对比。

背景：鼻气道狭窄可能位于蝶形孔的前方和/或后方。我们打算比较有鼻阻塞和无鼻阻塞患者在梨状孔前后的鼻气道情况：方法：比较鼻阻塞患者（病例）和外伤对照组鼻气道前方（CT-CSAant）和蝶形孔后方（下鼻甲头水平；CT-CSApost）的分割计算机断层扫描横截面积。CT-CSA 与鼻气流方向大致垂直。在梨状孔前方，它们分别向鼻底倾斜约 30o、60o 和 90o。在蝶形孔后方，它们分别与鼻底倾斜约 50o、80o 和 100o。在病例中，我们检查了主动前鼻测量与 CT-CSAant 和 CT-CSApost 的皮尔逊相关性：结果：56 个病例和 56 个对照组的 CT-CSApost 狭窄度和双侧 CT-CSApost 相似（P 均大于 0.2）。相反，病例的窄CT-CSAant和双侧CT-CSAant明显小于对照组（所有P均反30），病例的CT-CSApost-80明显低于对照组（中位数：0.84；下四分位数到上四分位数：0.55-1.13；1.0；0.88-1.16；Mann-Whitney U检验；P = 0.006）。双侧 CT-CSAant 与总吸气流量显著相关（所有 p 后（所有 p > 0.056））：结论：与对照组相比，骨骼性鼻腔狭窄导致的鼻腔阻塞患者梨状孔前的鼻腔气道较小。相反，鼻腔阻塞患者和非鼻腔阻塞患者蝶形孔后方的鼻腔气道相似大。此外，鼻阻塞患者的前鼻气道比后鼻气道狭窄。相反，对照组患者的前鼻气道与后鼻气道一样大。

期刊介绍： Head & Face Medicine is a multidisciplinary open access journal that publishes basic and clinical research concerning all aspects of cranial, facial and oral conditions. The journal covers all aspects of cranial, facial and oral diseases and their management. It has been designed as a multidisciplinary journal for clinicians and researchers involved in the diagnostic and therapeutic aspects of diseases which affect the human head and face. The journal is wide-ranging, covering the development, aetiology, epidemiology and therapy of head and face diseases to the basic science that underlies these diseases. Management of head and face diseases includes all aspects of surgical and non-surgical treatments including psychopharmacological therapies.
