Mandibular tori are a rare cause of difficult direct visualization of the upper aerodigestive tract. In the setting of aerodigestive tract pathology necessitating direct visualization, removal of mandibular tori may be required to facilitate treatment.
In the first case, large bilateral symmetric mandibular tori were removed to facilitate access to the anterior commissure and removal of a T1 glottic squamous cell carcinoma (SCC). In the second case, large bilateral mandibular tori were removed to access a markedly exophytic SCC in the right vallecula. Subsequently, the tumor was removed with robotic assistance with excellent exposure.
Both patients were free of recurrence at last follow-up.
Mandibular tori are an uncommon cause of difficult direct laryngoscopy. In situations that require direct visualization of the anterior commissure or base of tongue for diagnosis and management of lesions, surgical removal of the tori may be required as in the cases presented here.
下颌隆突是上呼吸道消化道直接可视化困难的罕见原因。在需要直接可视化的呼吸道消化道病理情况下，可能需要切除下颌隆突以促进治疗。
在第一例病例中，切除双侧对称的大型下颌隆突以利于接近前联合并切除T1期声门鳞状细胞癌（SCC）。在第二例病例中，切除双侧大型下颌隆突以接近右侧会厌谷明显外生性的SCC。随后，在机器人辅助下切除肿瘤，暴露良好。
在最后一次随访时，两名患者均无复发。
下颌隆突是直接喉镜检查困难的罕见原因。在需要直接观察前联合或舌根以诊断和处理病变的情况下，可能需要像此处所展示的病例一样手术切除隆突。
