Spontaneous and evoked laryngeal electromyography of the thyroarytenoid muscles: a canine model for intraoperative recurrent laryngeal nerve monitoring.
We sought to determine the feasibility of performing spontaneous and evoked intraoperative laryngeal electromyography (L-EMG) using nerve monitoring equipment and to compare recording electrode configurations and methods of recurrent laryngeal nerve (RLN) stimulation in dogs. ⋯ Typical patterns of nerve injury can be detected with this system of intraoperative L-EMG in a canine model. Quantitative measures of amplitude, latency, and wave duration in healthy and injured canine RLNs may be determined with this system.

Case ReportsHypertrophic anterior cervical osteophytes causing dysphagia and airway obstruction.
Hyperostosis of anterior cervical vertebral osteophytes can produce otolaryngological symptoms ranging from mild dysphagia, dysphonia, and foreign body sensation to severe food impaction and stridulous dyspnea. Airway compromise necessitating a tracheostomy is very rare. We discuss the case of an elderly man who presented with progressive dysphagia and a large hypopharyngeal mass as his initial manifestations of hypertrophic anterior cervical osteophytes. ⋯ The clinical, diagnostic, radiologic, and therapeutic principles involved in this case are presented and discussed. The recognition of hypertrophic osteophytes as a potential cause of common otolaryngological symptoms in the elderly population is paramount, as these symptoms can rapidly progress and lead to life-threatening airway obstruction. Medical and surgical interventions can be employed for the treatment of hypertrophic anterior cervical osteophytes, and they often result in favorable outcomes.

Comparative StudyComparison of intraoperative bleeding between microdebrider intracapsular tonsillectomy and electrocautery tonsillectomy.
We sought to assess the quantity of intraoperative bleeding from microdebrider intracapsular tonsillectomy (IT) relative to electrocautery tonsillectomy (ET). ⋯ Microdebrider IT produces more intraoperative bleeding than ET. The difference in blood loss is statistically but not clinically significant. Microdebrider IT causes bleeding within acceptable limits, and thus patients and physicians should not be discouraged from choosing this procedure solely on the basis of the amount of intraoperative blood loss.

Laryngopharyngeal reflux with sore throat: an ultrastructural study of oropharyngeal epithelium.
We performed an electron microscopic ultrastructural study of oropharyngeal epithelium in patients with laryngopharyngeal reflux (LPR) and sore throat to evaluate whether dilatation of intercellular spaces could be traced at this level. ⋯ Dilatation of intercellular spaces as a morphological marker can be traced in patients with LPR and sore throat at the level of the oropharynx. This contributes to a better understanding of the pathophysiology of LPR. If this finding is confirmed in a large series, it will represent a cost-effective, relatively noninvasive method for diagnosis of LPR.
