Vocal fold paralysis (VFP) is an important cause of respiratory and feeding compromise in infants. The causes of neonatal VFP are varied and include central nervous system disorders, birth-related trauma, mediastinal masses, iatrogenic injuries, and idiopathic cases. Bilateral VFP often presents with stridor or respiratory distress and can require rapid intervention to stabilize an adequate airway. Read More

Importance: Bilateral vocal fold paralysis (BVFP) in pediatric patients is a challenging entity with multiple causes. Traditional approaches to managing BVFP include tracheostomy, arytenoidectomy, suture lateralization, cordotomy, and posterior cricoid enlargement. These interventions are used to create a stable airway but risk compromising voice quality. Read More

Rheumatoid arthritis rarely involves the cricoarytenoid joint, symptoms of varying severity ranging from foreign body sensation, fullness or tension in the throat, hoarseness, odynophagia, speech or cough pain to stridor and respiratory distress during bilateral paralysis of the vocal cords. We are reporting a case of rheumatoid arthritis with bilateral involvement of the vocal cords. The diagnosis was clinically made and confirmed by endolaryngoscopy, responding to antirheumatic treatment but coming to the stage of permanent tracheotomy. Read More

Objectives: CO laser medial transverse cordotomy is a permanent static procedure performed to achieve adequate functional airway in cases of posterior glottic stenosis and bilateral vocal fold paralysis. Although it is the preferred method to manage long-term bilateral vocal fold immobility, it is widely believed that cordotomy has the potential to cause aspiration. The minimal existing data on the effect surgical enlargement of the glottic airway on swallowing function is heterogeneous. Read More

Objectives: Unilateral vocal fold paralysis (UVFP) impairs communication and reduces academic performance and social interactions in children. Deciding between temporary, permanent, or potentially destructive surgical interventions can be challenging, as there currently exists no reliable means of predicting vocal fold recovery or assessing the presence of vocal fold atrophy. Regarding vocal fold atrophy, optical coherence tomography (OCT) has been shown to be an appealing non-invasive alternative for accessing vocal fold structures. Read More

Objective: Recent advances in preoperative imaging techniques and intraoperative parathyroid hormone (ioPTH) assays have made single-gland, minimally invasive parathyroidectomy (MIP) the preferred treatment option for most patients with primary hyperparathyroidism (pHPT). Despite this evolution, a recommendation for bilateral neck exploration (BNE) with four-gland dissection in all patients has recently been advocated by a parathyroid surgical group. The current study compares the long-term outcomes of MIP with those of conventional BNE with four-gland dissection in patients with pHPT. Read More

Introduction: Bilateral vocal folds' immobility is a challenge in laryngology. Multiple procedures have been proposed to improve breathing by statically enlarging the glottal airway, what also results in loss of voice and aspiration. We proposed a technique to enlarge the posterior glottis by rotating the arytenoids on its axis, imitating the function of the posterior cricoarytenoid muscle, with the objective of evaluating the results regarding decannulation, voice quality, and bronchoaspiration.
