Plasmacytoma is a rare hematolymphoid malignancy. The three types of plasmacytoma, according to clinical features and morphological characteristics, include solitary bone plasmacytoma, extramedullary plasmacytoma (EMP), and multiple myeloma (MM). Although EMP of the head and neck region accounts for approximately 3% of all plasma cell tumors, the involvement of both paranasal sinuses is extremely rare. Herein, we describe a rare case of EMP involving both maxillary sinuses in a 73-year-old male patient who had achieved complete remission from MM following chemotherapy 2 years ago. The EMP was treated successfully with radiotherapy.

Background and Objectives: Voice change after thyroidectomy is a common complication that affects a patient’s quality of life. In this study, we aimed to compare voice outcomes between minimally invasive open hemithyroidectomy (MIOT) and conventional hemithyroidectomy.Materials and Method We enrolled 215 patients who underwent hemithyroidectomy performed by an experienced surgeon at our institute between June 2017 and December 2021. All patients underwent voice evaluations, including subjective and objective assessments, preoperatively and 2 weeks and 2 months postoperatively. Results: Sixty-one patients underwent MIOT (M group) and 154 patients underwent conventional hemithyroidectomy (C group). There were 50 female (82.0%) and 11 male (18.0%) in the M group, and 129 female (83.8%) and 25 male (16.2%) in the C group. In both groups, the thyroidectomy-related voice questionnaire score increased at 2 weeks and 2 months postoperatively. However, no statistically significant differences were observed between the two groups. Voice parameters were analyzed according to sex. There were some changes in the parameters in both groups. However, no statistically significant differences were observed between the two groups. Conclusion Our study showed no differences in the acoustic results between MIOT and conventional hemithyroidectomy.

Intraoperative neuromonitorng (IONM) has gained wide acceptance as a useful adjunct in identifying and preserving of recurrent laryngeal nerve (RLN) during thyroid surgery. The electromyographic endotracheal tube (EMG-ETT) method is the most widely used and well-validated method for thyroid IONM; however, malpositioning of the tube is a critical shortcoming of the EMG-ETT method. This is the main reason for the low positive predictive value of IONM in thyroid surgery. Needle and skin electrodes can obtain EMG signal regardless of patient position and are easy to apply during surgery and is economical compared to EMG-ETT method. New IONM system using needle or skin electrodes would be an alternative method which can overcome shortcomings of EMG-ETT.
