BACKGROUND/AIM: We examined the diagnostic performance of the tongue protrusion with phonation and open mouth (TOPPOM) method for visualizing structures of the oropharynx.
Transoral endoscopy was performed on 20 healthy participants to evaluate 12 oropharynx subsites under three conditions: open mouth (OM), phonation with open mouth (POM), and TOPPOM. Each subsite was scored from 0 to 2 depending on subsite visualization, and the scores were summed. Images of subsite-adjacent mucosa were similarly scored.
The total scores were significantly higher for TOPPOM than for POM and for POM than for OM. Such scores were observed for both the palatine arches, both palatine tonsils, the left lingual tonsillar sulcus, and the vallecula.
TOPPOM enables visualization of the oropharynx through transoral endoscopic examination, and TOPPOM with conventional transnasal endoscopy may enable early detection of oropharyngeal carcinomas and lesions and improve the performance of pre- and post-treatment evaluations.
背景/目的：我们研究了发声伸舌与张口（TOPPOM）方法在可视化口咽结构方面的诊断性能。
对20名健康参与者进行经口内镜检查，以评估在三种情况下的12个口咽亚部位：张口（OM）、张口发声（POM）和TOPPOM。根据亚部位的可视化情况，每个亚部位从0到2进行评分，并将分数相加。对亚部位相邻黏膜的图像进行类似评分。
TOPPOM的总分显著高于POM，POM的总分显著高于OM。在腭弓、双侧腭扁桃体、左侧舌扁桃体沟和会厌谷均观察到这样的分数。
TOPPOM能够通过经口内镜检查可视化口咽，TOPPOM与传统经鼻内镜检查相结合可能有助于早期发现口咽癌和病变，并提高治疗前和治疗后的评估效果。
