Bilateral vocal cord palsy after total thyroidectomy–A new treatment–Case reports

چکیده
INTRODUCTION Dyspnea due to bilateral vocal cord palsy after total thyroidectomy (BVCPATT) is a life-threatening complication; nevertheless, we try to avoid tracheotomy. METHODS Using normalized glottal area (NGA), we retrospectively studied 14 patients with BVCPATT. Nine patients without dyspnea were treated conservatively, while five with dyspnea received immediate bilevel positive air-way pressure (BiPAP) treatment. Both right and left recurrent nerves were grossly intact during surgery. RESULTS The mean NGA during inspiration of five patients with dyspnea was less than that of nine patients without (6.21±1.57 (mean±standard deviation) vs. 20.5±9.5; p=0.001). The mean age of patients with dyspnea was more than that of patients without (61.6±15.6 vs. 38±10.2; p=0.007). Five patients with dyspnea that occurred at 0-8days post operation recovered within 3-17days after BiPAP. CONCLUSION Dyspnea occurred in patients with BVCPATT who were relatively older. The mean NGA during inspiration in patients with dyspnea was less than that in patients without. BiPAP might be a new treatment for dyspnea.

A Case of Transient Local Anesthetic Induced Bilateral Vocal Cord Palsy
We report a rare case of bilateral vocal cord palsy following total thyroidectomy with successful extubation within 12 hours. The patient is a 33-year-old lady who underwent uneventful total thyroidectomy for compressive symptoms. Thirty minutes after extubation, she developed stridor and the flexible laryngoscopy showed bilaterally adducted vocal cords. The patient, thus, was reintubated and a...

This paper reports the case of a 65-year-old woman with a history of mild arterial hypertension who presented with acute pulmonary edema immediately after a total thyroidectomy. The edema was found to have been caused by an acute upper airway obstruction secondary to bilateral vocal cord paralysis. Her pulmonary edema resolved with treatment including reintubation, mechanical ventilation with p...

Thyroid surgery in recent years is generally considered quite safe. Better preoperative preparation and proper surgical techniques of thyroidectomy have minimized complications to less than 2-3%. Bilateral recurrent nerve palsy is the rarest of all complications, with a reported incidence varying between 0.4% to 14 %, but can be potentially fatal if
متن کاملTreatment of bilateral vocal cord paralysis following permanent recurrent laryngeal nerve injury.
Bilateral vocal cord paralysis is a serious illness requiring emergency intervention to resolve the potentially life-threatening respiratory distress. Several surgical procedures were proposed to help improve the airway and to eliminate the tracheostoma in those patients with permanent paralysis. All the procedures have their own advantages and disadvantages. We conducted a retrospective study ...
