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.
Procedure
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.
Indications
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
Contraindications
Active bleeding or infection, specific anatomical malformations of the airway
Instrumentation
Setup
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.
Preoperative Workup
Complete history and focused physical exam with anesthesia evaluation
Anatomy and Landmarks
Labelled stills are used to demonstrate the anatomy at multiple levels from superior to inferior including the levels of the epiglottis, vocal cords, trachea, and carina.
Advantages/Disadvantages
