Microlaryngoscopy in a Child with Normal Anatomy

Contributor: Thomas Mitchell

A laryngoscope is used to allow magnified visualization of the anatomy of the larynx in a pediatric patient.  Labelled stills are used to demonstrate specific anatomy and landmarks.  This procedure is indicated to diagnose and/or treat pathology of the airway and vocal cords.  However, no pathology is seen in this patient.

Microlaryngoscopy in a Child with Normal Anatomy: The patient is placed under general anesthesia and intubated. A mouth retractor and guard is introduced to protect the teeth. The laryngoscope is advanced to allow for visualization of the structures of the larynx. The image is magnified and transmitted to binoculars and a separate screen.
Diagnosis of suspected laryngeal pathology as indicated by hoarseness, breathing difficulties, laryngeal trauma etc. Also, treatment of selected laryngeal pathology including removal of foreign objects, biopsy/removal of masses etc
Active bleeding or infection, specific anatomical malformations of the airway
