PurposeThis study aims to determine Euclidean distances between landmarks structures in larynx and pharynx to optimize endoscopic shaft designs with regard to gentle and patient oriented handling.MethodsFour Euclidean distances between landmarks in larynx and pharynx were analyzed based on CT data of 66 patients.距离(1):C1颈椎(寰椎)口下唇-咽后壁,寰椎前结节前缘。距离(2):咽后壁邻近C1-梨状窝入口。距离(3):悬雍垂下缘-会厌上缘。距离(4):谷底-咽后壁。用经口硬性喉镜观察声门所需的最小视野角α是从距离(2)和(4)中三角推导出来的。结果测量的平均欧几里得距离:距离(1):男性90.7 mm ± 6.9 mm,女性86.9 mm ± 5.9 mm。(2):73.7 mm ± 13.4 mm和56.2 mm ± 7.6 mm。(3):25.2 mm ± 8.6 mm和18.5 mm ± 6.8 mm。(4)结论:与预期的一样,在距离(1)-(4)上,可以观察到统计学上显著的性别相关差异。结果表明,经口喉镜的长度不应小于110 mm,最小视场角α= 17°才能充分观察喉入口。
PurposeThis study aims to determine Euclidean distances between landmark structures in the larynx and pharynx to optimize endoscope shaft designs with regard to gentle and patient-oriented handling.MethodsFour Euclidean distances between landmarks in the larynx and pharynx were analyzed based on CT data of 66 patients. Distance (1): labium inferius oris—posterior pharyngeal wall at the cervical vertebra C1 (atlas), anterior edge of the tuberculum anterius atlantis. Distance (2): posterior pharyngeal wall adjacent to C1—entrance of pyriform sinus. Distance (3): inferior edge of the uvula—superior edge of the epiglottis. Distance (4): base of the vallecula—posterior pharyngeal wall. The minimum angular field of viewαrequired to observe the glottis with a rigid transoral laryngoscope was derived trigonometrically from distances (2) and (4).ResultsAverage Euclidean distances measured: Distance (1): 90.7 mm ± 6.9 mm in men and 86.9 mm ± 5.9 mm in women. (2): 73.7 mm ± 13.4 mm and 56.2 mm ± 7.6 mm. (3): 25.2 mm ± 8.6 mm and 18.5 mm ± 6.8 mm. (4): 20.8 mm ± 4.6 mm and 16.5 mm ± 3.4 mm.α: 16.0° ± 3.9° and 16.6 ± 4.3°.ConclusionsAs expected, statistically significant sex-related differences could be observed for distances (1)–(4). The results indicate that the length of transoral laryngoscopes should not be below 110 mm and that a minimum angular field of view ofα= 17° is required to fully observe the laryngeal inlet.
