Airway Compromise in Thyroplasty Surgery

Laryngeal framework surgery (thyroplasty)

Phonosurgery is defined as 'surgery specifically designed to alter the voice' (Von Leden, 1991). It can be divided into four categories: (1) Vocal fold surgery; (2) Laryngeal framework surgery; (3) Neurolaryngeal surgery; (4) Post-laryngectomy voice rehabilitation. All the above procedures require a knowledge of the anatomy and the physiology of the vocal folds. It is important to preserve the ...

Effect of Medialization Thyroplasty on Glottic Airway Anatomy: Cadaver Model.

OBJECTIVES The purpose of this study was to investigate the change in airway dimensions after medialization thyroplasty (MT) using a cadaveric model. Helical computerized tomography (CT) was performed before and after placement of a silastic block in human larynges to investigate the effect on airway anatomy at the level of the glottis. Tissue density (TD) of the medialized vocal fold (VF) was ...

Trichobezoar Causing Airway Compromise during Esophagogastroduodenoscopy

Objectives. (1) Report the case of a 5-year-old female with trichotillomania and trichophagia that suffered airway compromise during esophagogastroduodenoscopy for removal of a trichobezoar. (2) Provide management recommendations for an unusual foreign body causing extubation and partial airway obstruction. Methods. Case report of a rare situation of airway compromise caused by a trichobezoar. ...

Impending Airway Compromise due to Cystic Hygroma

We report on a 3-month-old infant, who arrived in the pediatric emergency department (ED) with a cervical cystic hygroma causing an impending compromise of the airway. We recognize that such a lesion can rapidly progress, and the judicious use of imaging in the ED may help to avoid airway compromise and possibly fatal complications.
