A randomized prospective controlled study was made in order to find out if voice related acoustical measures show usable predictive pathologies in patients with laryngo-pharyngeal reflux (LPR). The used acoustical program was an advanced MDVP (multi-dimensional voice program) by Laryngograph Ltd. which routinely adjusts to well defined sustained tones measures as well as reading of a standard t...

A 16-year-old female basketball player presented with a 2 1/2-year history of exercise-induced severe dyspnea, stridor, and mild wheezing that did not respond to prophylactic treatment with beta-agonists and cromolyn. Spirometric data at rest were normal, but flow-volume loops during exercise suggested a variable extrathoracic obstruction. Laryngoscopic evaluation while the patient was riding a...

1. A surface electrode was used to record electromyographic activity of the posterior cricoarytenoid muscle during breathing in normal subjects and patients with airflow obstruction. 2. Phasic activity of the posterior cricoarytenoid muscle was demonstrated. This was present on inspiration and absent on expiration. 3. Phasic inspiratory activity in normal subjects was present only during period...

In five patients with multiple system atrophy, electromyographic studies using a new surface electrode technique, showed unequivocal evidence of denervation of the posterior crico-arytenoid muscle, and in three of them, of the interarytenoid muscle or crico-pharyngeal sphincter. By comparison, only minor electromyographic abnormalities were found in one-third of patients with other extra-pyrami...

OBJECTIVES/HYPOTHESIS Airway obstruction is an uncommon presentation of unilateral laryngeal paralysis. We have observed two mechanisms of obstruction: arytenoid prolapse and inappropriate adduction of the paralyzed vocal fold. We evaluated arytenoid abduction (AAb) and recurrent laryngeal nerve (RLN) reinnervation as treatments for airway obstruction in patients with unilateral laryngeal paral...

Granular cell tumors are benign subcutaneous or submucosal lesions of neurogenic origin. In this case study one patient was diagnosed and treated successfully with complete surgical resection of a laryngeal granular cell tumor that was originated from the left arytenoid region that very rare location. There is no evidence of recurrence 2 years after surgery. Granular cell tumors should be consi...

Turkey has very rich quince genetic resources, and the country currently dominates world quince production. In particular, the northeastern part of the country has notable Cydonia oblonga Mill. germplasm. Authenticating the identity of germplasm resources of C. oblonga Mill. would be of great value for breeding practices. In the present study, genetic variations of 14 C. oblonga Mill. genotypes...

STUDY DESIGN A case of arytenoid dislocation after anterior cervical corpectomy and fusion (ACCF) is reported. OBJECTIVE To emphasize that arytenoid dislocation could be a possible cause of prolonged hoarseness in patients after ACCF. SUMMARY OF BACKGROUND Prolonged hoarseness is a common postoperative complication of cervical surgeries, especially in the anterior approach. Postoperative ho...
