To investigate the changes of speech and voice acoustics in patients with thyroid disease before and after operation, get objective values, and conducive to guiding the clinical diagnosis and treatment and recurrent laryngeal nerve protection. A total of 216 patients undergoing thyroid surgery from October 2015 to October 2016 were treated with TVQ and GRBAS at 1 day before surgery, 1 week, 1 month, and 3 months postoperatively to phonological assessment, and Praat software was used to collect and analyze the acoustic acoustics index for preoperative and postoperative comparative analysis. All patients did not damage the recurrent laryngeal nerve, unilateral or bilateral thyroid subtotal resection (no exploration of recurrent laryngeal nerve) in patients with postoperative speech and voice index F0 was decreased at 1 week after surgery (<0.05), the other indicators did not change significantly; difference was found out in single-sided total thyroidectomy+ipsilateral central area lymph node dissection, bilateral thyroidectomy+unilateral central area lymph node dissection (exploration of unilateral recurrent laryngeal nerve) in patients with TVQ, GRBAS and F0, HNR after surgery 1 week compared with preoperative (<0.05), However, there was no significant difference 3 months; TVQ, GRBAS and F0, HNR were significantly changed in patients with bilateral thyroidectomy+bilateral central lymph node dissection (revealed bilateral recurrent laryngeal nerve) at 1 week after operation (>0.05). F0 and HNR were lower than those before operation, and the patients were treated with Jitter and Shimmer. The patients were treated with TVQ, GRBAS, Jitter and Shimmer before operation, however, the majority of patients' TVQ, GRBAS, Jitter, Shimmer can be restored to preoperative level after surgery 3 months (>0.05). The appearance of speech and voice problems in patients after thyroid surgery may increase with the expansion of the surgical range, the change in speech and voice after neck lymph node dissection is reversible.

Background: Benign laryngeal lesions, characterized by non-cancerous growths in the larynx, significantly impact voice quality and respiratory function. These lesions, which include vocal cord polyps, nodules, papillomas, and cysts, often result from factors such as vocal abuse, viral infections, and chronic inflammation. While studies on benign laryngeal lesions are well-documented globally, data specific to Northern Nigeria remains sparse.

Article Synopsis
- Intraoperative neuromonitoring (IONM) is valuable in thyroid/parathyroid surgeries and aims to assess vocal cord paralysis (VCP) through variations in recurrent laryngeal nerve (RLN) amplitudes.
- A study involving 728 RLNs found that specific amplitude ranges (particularly V2 at 117-216 μV) effectively predicted VCP with high sensitivity and specificity.
- The findings suggest that measuring V2 amplitudes can serve as a reliable method to predict postoperative VCP, especially when initial vagus nerve exposure is limited.

Introduction And Importance: Surgical management of huge multi-nodular goiters present clinical and surgical management dilemma among practicing surgeons. Thyroidectomies pose huge risk potential when performed by relatively inexperienced and junior operators.
Case Presentation: We present a case of a 40-year-old lady who had presented at our center with a ten-year history of painless anterior neck swelling.
Preoperative Nutritional Status Influences Enteral Nutrition Weaning 6 Months Post-Surgery in Patients with Esophageal Cancer.

Objective: This study aimed to clarify whether nutritional status at admission affects enteral nutrition weaning 6 months after surgery in patients with esophageal cancer.
Methods: This was a retrospective study of 81 patients who underwent subtotal esophageal cancer resection between April 2014 and February 2016. The survey items were as follows: 1) sex, 2) age, 3) presence or absence of family members living together, 4) clinical stage, 5) surgical procedure, 6) reconstructed organs, 7) nutritional status at admission, 8) presence or absence of postoperative complications (anastomotic leakage, chylothorax, and recurrent laryngeal nerve paralysis), and 9) presence or absence of treatment other than surgery (chemo- or radiotherapy).
