Laryngeal trauma is rare but life-threatening emergency. Main cause of the trauma includes traffic accident, fall down, machinery injury, and stab. This type of injury not only makes tremendous bleeding and hemodynamic instability, but also intimidates a patency of upper airway which leads to acute respiratory failure. If acute complication be resolved, laryngeal destruction would prospectively result in dysphagia, chronic aspiration, and dysphonia. In many previous cases, severe laryngotracheal trauma have been treated via primary approximation followed by conservative care and rehabilitation. We present a case of total laryngectomy, a rare strategy for laryngeal trauma on a patient with severe laryngeal framework destruction after stabbing.

Background: Intraoperative neuromonitoring (IONM) using adhesive skin electrodes has been reported to be useful method for preserving recurrent laryngeal nerve (RLN) in thyroid surgery. The aim of this study is to investigate the usefulness of IONM using adhesive skin electrodes in minimally invasive open hemithyroidectomy. Materials and Methods: A retrospective study was conducted on 23 patients diagnosed with micropapillary thyroid carcinoma from May 2020 to August 2022 who underwent minimally invasive open hemithyroidectomy. Adhesive skin electrodes were attached to the skin in the area of the lateral border of the thyroid cartilage lamina. Hemithyroidectomy was performed by approaching between sternocleidomastoid and strap muscles, after a 3-4 cm horizontal skin incision. We collected the data regarding age, sex, mean amplitude and latency of evoked electromyogram (EMG) (V1, R1, R2, V2). Results: The amplitude of EMG from vagus and RLN was successfully measured. The mean amplitude was measured as 239.2 μV for V1, 278.0 μV for R1, 362.1 μV for R2, and 307.0 μV for V2, respectively. Conclusion: The monitoring using adhesive skin electrodes is good alternative method of IONM using EMG endotracheal tube for preserving RLN during minimally invasive open hemithyroidectomy.

External auditory canal (EAC) stenosis is an obstruction of the orifice of the ear canal, which may be congenital or acquired. EAC stenosis is a very rare disease that is difficult to treat and recurs frequently. However, there is no gold standard for maintaining patency of medical and surgical treatment of EAC stenosis. Although various methods have been reported, the progression of stenosis or restenosis remains a major problem. we report a case of effective prevention of restenosis after EAC stenosis surgery using a customized earmold stent.

Follicular lymphoma is a characteristic clinicopathologic term of centrioles and centroblasts of germinal center B cell origin. Pediatric follicular lymphoma is a variant type of follicular lymphoma in children. Unlike follicular lymphoma, pediatric follicular lymphoma is an indolent lymphoma that rarely recurs and progresses to other organs, but has no clear diagnostic criteria. The authors report and review a case of pediatric follicular lymphoma diagnosed by tonsillectomy for recurrent tonsillitis.
