RATIONALE: Arytenoid dislocation is very rare and may be misdiagnosed as vocal cord paralysis or a self-limiting sore throat. PATIENT CONCERNS: A 70-year-old male (70 kg, 156 cm) was scheduled for transurethral resection of bladder tumors. A McGrath videolaryngoscope, with a basic cuffed Mallinckrodt oral tracheal tube of 7.5 mm internal diameter, was used to successfully intubate his trachea. The duration of surgery was 25 minutes. In the recovery room, he complained of sore throat and dyspnea with inspiratory stridor, which were not resolved after intravenous injection of 10 mg of dexamethasone...

This case report describes the use a new flexible robotic system in otolaryngology, the FlexRobot(®) for cricopharyngeal myotomy in cadaver dissections, and for the treatment of a patient with esophageal stenosis and secondary dysphagia and dysphonia. The Flexrobot(®) facilitates access to the hypopharynx with increased proximity to the surgical field and improved optics, allowing more exact dilatation and injection in our patient. It also would allow surgeons to reach deep inside the cavity of the hypopharynx into anatomical regions that are typically inaccessible without an open approach, as shown in our cadaveric procedure, where full exposure of the posterior aspect of the cricopharyngeus and isolation of the muscle belly were achieved...

OBJECTIVES/HYPOTHESIS: Determination of superior laryngeal nerve (SLN) involvement in addition to recurrent laryngeal nerve (RLN) paralysis in patients with unilateral vocal fold paralysis (UVFP) relies on traditional, qualitative laryngeal electromyography (LEMG) examination. It is necessary to develop a quantitative measurement that reflects the degree of denervation of the cricothyroid (CT) muscle. The present study aimed to establish a standard quantitative assessment of CT function in patients with UVFP by measuring the turn frequency...

Schwannomas are peripheral nerve neurogenic tumours and although not common, laryngeal schwannomas can provide a unique challenge in diagnostic and treatment management. There are limited reports in the literature on approaches to management. A 73-year-old lady presented to the otolaryngology department after a MRI scan demonstrated an incidental right supraglottic mass. Further investigations included CT scanning and microlaryngoscopy, which only confirmed the presence of the mass with no histology diagnosis...

BACKGROUND: Long quiet eye (QE) duration is central to expertise in sports, while cognitive "slowing down" has been identified as a perceptual skill possessed by skilled surgeons. Eye-tracking evidence is lacking about the relationship of QE duration to slowing down in surgeons. The aim of this study was to examine QE duration, hand movement time (MT), fixation location, and fixation duration in highly experienced (HE) and less experienced (LE) surgeons. METHODS: A mobile eye tracker and camera recorded coupled gaze and hand movements...

In 30% of patients with epilepsy seizure control cannot be achieved with medications. When medical therapy is not effective, and epilepsy surgery cannot be performed, vagus nerve stimulator (VNS) implantation is a therapeutic option. Laryngeal patterns in vagus nerve stimulation have not been extensively studied yet. The objective was to evaluate laryngeal patterns in a cohort of patients affected by drug-resistant epilepsy after implantation and activation of a vagus nerve stimulation therapy device. 14 consecutive patients underwent a systematic otolaryngologic examination between 6 months and 5 years after implantation and activation of a vagus nerve stimulation therapy device...

OBJECTIVE: Thyroidectomy may be performed for clinical indications that include malignancy, benign nodules or cysts, suspicious findings on fine needle aspiration biopsy, dysphagia from cervical esophageal compression, or dyspnea from airway compression. About 1 in 10 patients experience temporary laryngeal nerve injury after surgery, with longer lasting voice problems in up to 1 in 25. Reduced quality of life after thyroid surgery is multifactorial and may include the need for lifelong medication, thyroid suppression, radioactive scanning/treatment, temporary and permanent hypoparathyroidism, temporary or permanent dysphonia postoperatively, and dysphagia...

OBJECTIVES/HYPOTHESIS: The relevance of the cricothyroid (CT) muscle in patients with unilateral vocal fold paralysis (UVFP) remains controversial. To clarify the functional significance of the CT muscle in patients with UVFP, the confounding effect of the severity of recurrent laryngeal nerve injury should be taken into consideration. In the present study, quantitative laryngeal electromyography (LEMG) was used to measure the severity of paralysis of the thyroarytenoid-lateral cricoarytenoid (TA-LCA) muscle complex to allow the functional contribution of the CT muscle to be determined...
