Evaluation Techniques

The physicians at The Voice Clinic of Indiana approach each patient with a thorough history of the presenting problem, followed by a thorough head and neck examination.  Unique to The Voice Clinic are techniques learned and perfected through fellowship training and subsequent experience.  Such evaluation techniques include:


Stroboscopy, or videostroboscopy, utilizes high-definition video equipment and strobe lighting to capture vibratory changes that can affect vocal cord function.  Even the most subtle of changes to the finely orchestrated process of voice production at the level of the vocal cords can affect an individual’s voice.  Any comprehensive voice evaluation should be accompanied by stroboscopy performed by a highly trained individual.  At The Voice Clinic of Indiana, stroboscopy is performed through multiple methods based on patient’s needs and comfort by dedicated voice specialists.

Bronchoscopy utilizes high-definition video equipment  to evaluate the airway below the vocal cords, including the trachea and bronchi.  While other specialists in Indiana require anesthesia and a hospital setting to perform this diagnostic evaluation for breathing problems, the doctors at The Voice Clinic can do so with only topical anesthesia.  Not only does this save patients from an operating room-based procedure, but it also expedites evaluation and diagnosis for patients.

Laryngeal EMG
Patients suffering from neurological voice disorders often have difficulty in findings expert evaluation that allows for diagnosis and treatment.  At The Voice Clinic of Indiana, voice specialists with extensive experience with neurolaryngologic disorders (spasmodic dysphonia, vocal tremor, Parkinson’s disease, and others) can combine their clinical assessments with laryngeal electromyography (LEMG) to further define the disorder.  Diagnostic LEMG involves the use of fine wires inserted into the complex musculature within and surrounding the voice box (larynx) to identify patterns that lead to directed patient treatment.

In addition to the evaluation and treatment of neurological disorders of the larynx, some patients have movement disorders elsewhere in the head and neck. Patients with oromandibular dystonia, cervical dystonia, and other movement disorders of the head and neck may benefit from diagnostic EMG.

Sleep Endoscopy
For patients with obstructive sleep apnea, it has long been a challenge for specialists to identify the anatomic areas causing the obstruction so that the correct surgical options can be discussed.  Central to this problem is that sleep simply cannot be reproduced in a clinic setting.  Dr. Parker has teamed with anesthesiologists to create a protocol for putting patients into an appropriate level of sleep in order to appropriately evaluate the airway.  This short and safe procedure is done in an operating room setting and allows Dr. Parker to create a targeted surgical plan customized to patient anatomy and physiology.
