Filter by:One of the major risks of endocrine surgery is recurrent nerve palsy (RNP), leading to vocal folds (VF) immobility. It happens in 5% of cases, leading to high morbidity: dysphonia, aspirations, impossibility to work. Guidelines recommend to systematically perform a nasofibroscopy before and after surgery to check vocal fold mobility. However, due to the decreasing number of specialists, the cost of decontamination, and discomfort of this procedure, these guidelines are insufficiently followed. Transcutaneous Laryngeal Ultrasonography (TLU) appears a good alternative to nasofibroscopy in evaluating VF mobility, as assessed by the recent flourishing literature. Our team is a leader in this research by having developed a dedicated software, which provides objective measures of VF mobility. The aim of the present protocol is to validate the power of TLU for the diagnosis of RNP on a large cohort of patients operated on endocrine surgery. It is a prospective multicentric study that will blindly compare TLU and nasofibroscopy, the latter being the gold standard. TLU is cost effective and painless; its learning curve is fast. If validated, it may be offered as a good alternative to nasofibroscopy in RNP detection and prognosis.
Thyroidectomy is a frequently performed surgeon by the head and neck and endocrine surgeons. In recent years, surgical techniques and technological developments have resulted in a significant reduction in complication rates. Despite these advances, there is still a great deal of anxiety about the sound problems that can be experienced in patients after surgery. In the past years,the investigators have tried to prevent recurrent nerve paralysis by using intraoperative nerve monitoring (IONM). The use of IONM has begun to be preferred by many surgeons in the investigator's country. However, the use of IONM decreases the number of recurrent nerve paralysis are still being discussed and many studies have been done. In this study, it is aimed to prevent the formation of recurrent nerve paralysis in order to safely carry out the IONM by removing the effects of neuromuscular blockade drugs using sugammadex sodium medicine in the thyroidectomy operations.
Thyroidectomy is a common surgical procedure in France. Recurrent paralysis is one of the main complications. Oral corticosteroid therapy are frequently used at a dosage of 1mg/kg for seven days, in case of recurrent paralysis to obtain remobilization as early as possible. The main objective is to evaluate the efficacy of oral corticosteroid therapy in remobilization of vocal cords at seven days in patients with unilateral recurrent paralysis after thyroidectomy.
Laryngeal motor and sensory nerve dysfunction may cause phonation and swallowing disturbance, which often happens after the treatment for laryngopharyngeal and esophageal cancer and may induce fatal complications such as aspiration pneumonia. By the conventional examinations, the tiny sensory or motor changes are hard to be detected before complete vocal paralysis. It is utmost important to establish a comprehensive quantitative method which is sensitive enough to evaluate the neuromuscular functions. The present project will evaluate the laryngeal nerve function by quantitative laryngeal electromyography, which was developed by the research team, and another novel examination technique, mucosal membrane sensation test. The comprehensive method is expected to grade the laryngeal nerve injuries quantitatively before the significant symptoms or complications and can also help to evaluate the treatment effect from medicine, rehabilitation or surgery.
Herpes esophagitis presents a clinical diagnostic challenge. The investigators report the first case of herpes esophagitis presenting as vocal fold palsy in an immunocompetent host. The investigators case highlights the importance of performing a detailed laryngoscopic examination in any patient with prolonged husky voice.
This study evaluates a medialization implant to treat vocal cord paralysis, to permit it to adjust the quality of the voice under local or general anesthesia. The aim is to restore phonation using a porous titanium prosthesis in laryngeal surgery.
