Photograph of preoperative setting for tumor resection of the right side vestibular schwannoma in Case 1. An endotracheal tube was placed on the left angle of his mouth, the side contralateral to the operation. We placed electrode needles into the right (ipsilateral) facial muscles to monitor his facial electromyographic responses.

The endotracheal tube was fixed on the left corner of the mouth and electrode needles were inserted into the right facial muscles to monitor his facial electromyographic (EMG) responses (Fig. 1).
a: In Case 1, computed tomography (CT) 12 h after surgery shows remarkable swelling of the left submandibular gland (arrows) and surrounding soft tissue. The larynx is compressed and deformed. b: CT 7 days after surgery demonstrates the improvement of the edematous change of the left submandibular gland and the larynx.

A computed tomography (CT) scan indicated marked swelling of the submandibular gland and the surrounding soft tissue compressing the trachea, which was shifted to the right side (Fig. 2a). After administration of antibiotics and corticosteroids, the submandibular edema regressed rapidly within 7 days (Fig. 2b), and the endotracheal tube was removed on the third treatment day.
