Objectives/Hypothesis: The varied etiology of bilateral vocal cord immobility (BVCI) requires a wide range of surgical approaches. A new endolaryngeal thread guide instrument (ETGI) is presented here for a minimally invasive endoscopic lateropexy of the arytenoid cartilage, which might serve as a basis for a simple solution for the main types of BVCI.Study Design: Prospective study of BVCI patients who underwent surgery, including 22 bilateral vocal cord paralyses (BVCP), 12 mechanical fixations (MF), 10 posterior glottic stenoses, and two rheumatoid ankyloses.Methods: The ETGI is based on a built-in movable curved blade with a hole at its tip to guide a thread in and out again between the skin and the laryngeal cavity. The loops formed around the arytenoid cartilage cause abduction. In cases of fixations, the cricoarytenoid joints were properly mobilized as a first step with a combination of cold technique and CO 2 laser.Results: As spirometric tests proved, 32 patients achieved improved breathing ability. One temporary tracheostomy was necessary and one patient with ongoing radiotherapy could not be decannulated. Subjectively, twelve patients' voices improved or approximated normal quality due to complete vocal cord recoveries on at least one side after lateropexy was ceased. Incomplete recovery with more or less impaired voice was observed in 16 cases. Three MF patients and two BVCP patients with poor overall health condition had severe dysphonia. Conclusions:Combined with simple and readily available methods, endoscopic arytenoid lateropexy is an effective solution for BVCIs with various etiologies. The ETGI facilitates this procedure with rapid and safe creation of fixating loops at the proper position.

Our morphometric study proved that organ-preserving EAAL provided more space in the posterior glottic area. Fibrous reconnection and contraction of the scar can be minimized in this way, which may be the clinical efficacy explanation.

Purpose Endoscopic arytenoid abduction lateropexy (EAAL) is a reliable surgical solution for the minimally invasive treatment of bilateral vocal fold palsy (BVFP), providing a stable airway by the lateralization of the arytenoid cartilages with a simple suture. The nondestructive manner of the intervention theoretically leads to higher regeneration potential, thus better voice quality. The study aimed to investigate the respiratory and phonatory outcomes of this treatment concept. Methods 61 BVFP patients with significant dyspnea associated with thyroid/parathyroid surgery were treated by unilateral EAAL. Jitter, Shimmer, Harmonics to Noise Ratio, Maximum Phonation Time, Fundamental frequency, Voice Handicap Index, Dysphonia Severity Index, Friedrich’s Dysphonia Index, Global-Roughness-Breathiness scale, Quality of Life, and Peak Inspiratory Flow were evaluated 18 months after EAAL. Results All patients had a stable and adequate airway during the follow-up. Ten patients (16.4%) experienced complete bilateral motion recovery with objective acoustic parameters in the physiological ranges. Most functional results of the 13 patients (21.3%) with unilateral recovery also reached the normal values. Fifteen patients (24.6%) had unilateral adduction recovery only, with slightly impaired voice quality. Eleven patients (18.0%) had false vocal fold phonation with socially acceptable voice. In 12 patients (19.7%) no significant motion recovery was detected on the glottic level. Conclusion EAAL does not interfere with the potential regeneration process and meets the most important phoniatric requirements while guaranteeing the reversibility of the procedure—therefore serving patients with transient palsy. Further, a socially acceptable voice quality and an adequate airway are ensured even in cases of permanent bilateral vocal fold paralysis.

Background We report a case of bilateral malignant otitis externa complicated with bilateral petrous internal carotid artery pseudoaneurysms and their successful treatment with a flow diverter. Case report A 68-year-old woman with serious complications of type II diabetes mellitus had malignant otitis externa on the right side. She was treated with combined antibiotic therapy and underwent mastoidectomy for mastoiditis. She presented at our hospital with acute hemorrhage from the right external auditory canal. The emergency computed tomography (CT) angiography revealed a multiobulated pseudoaneurysm at the petrous segment of the right internal carotid artery. The pseudoaneurysm was treated with a 5 × 40-mm Surpass flow diverter. Three months later, she developed a malignant external otitis on the left side. As the infection progressed, a left-sided mastoiditis, a brain abscess, and a pseudoaneurysm at the petrous segment of the left internal carotid artery developed. The pseudoaneurysm caused bleeding from the left ear, and was treated with a 5 × 50-mm Surpass flow diverter. No recurrent bleeding was observed. Four months later, a follow-up angiography showed complete occlusion of the pseudoaneurysm on the left side, but a residual aneurysm could be detected on the right side. One year after the first intervention, the follow-up CT and magnetic resonance angiography revealed the complete occlusion of the aneurysms bilaterally. Conclusion The use of a flow diverter appears to be an efficient and safe method to occlude carotid pseudoaneurysms even in an inflammatory milieu.
