Our Services
Three specialist clinics for voice, swallowing and airway disorders, each built around precise diagnosis and a treatment plan matched to the cause.
Voice Clinic
Hoarseness, vocal fatigue and voice loss investigated properly, with videolaryngoscopy and stroboscopy to see exactly what the vocal folds are doing, then a treatment plan matched to the cause.

Swallowing Clinic
Swallowing: effortless, until it isn’t.
Difficulty swallowing, choking and food sticking are assessed with endoscopic swallow testing across real food consistencies, so the advice you get is based on what you can actually manage safely.

Airway Clinic
Noisy breathing, stridor and narrowing of the airway need urgent, precise assessment. Airflow is measured before and after treatment, so improvement is demonstrated rather than assumed.

World-standard tools for precise diagnosis, early intervention and minimally invasive management of voice, airway and swallowing disorders.
Pentax HD Flexible Laryngoscope with I-SCAN (NBI)
High-definition imaging with advanced tissue visualization
- High-definition imaging provides detailed visualization of the vocal cords and surrounding structures
- Equipped with I-SCAN, a selective digital light filter similar to Narrow Band Imaging, highlighting blood vessel patterns beneath the mucosa to detect very early cancers and subtle abnormalities
- Ultra-thin 3.4mm design allows safe, comfortable use even in newborns and infants without anesthesia
- Offers unmatched clarity, ideal for precise assessment of persistent hoarseness, throat discomfort, or professional voice users
Stroboscopy
Slow-motion visualization of vocal fold vibrations
- Provides slow-motion visualization of vocal fold vibrations, detecting subtle mucosal abnormalities and irregularities in vocal fold movement that are not visible with standard lighting or the naked eye
- Uses high-frequency Xenon light, offering best-in-class imaging quality for precise assessment
- Enables objective tracking of voice improvement during therapy or post-surgery recovery
- Especially valuable for singers, voice actors, teachers, and speakers, allowing personalized therapy or interventions to restore voice quality and prevent further injury
VitalStim Therapy
FDA-approved neuromuscular electrical stimulation
- A USFDA-approved neuromuscular electrical stimulation system for safe and effective swallowing rehabilitation
- Can be combined with biofeedback therapy, enabling patients to visualize and actively participate in their progress
- Strengthens the muscles involved in swallowing, reducing aspiration risk and improving safety while eating
- Ideal for patients recovering from surgery, neurological disorders, or chronic swallowing difficulties
Electrical Laryngeal Stimulation
Targeted electrical stimulation for voice disorders
- Provides targeted electrical stimulation to treat vocal cord paresis, muscle tension dysphonia, and other voice disorders
- Supports muscle re-education and enhances recovery of vocal cord function, often combined with personalized voice therapy
- Helps patients regain a clearer, stronger voice faster, reducing overall therapy duration
- Improves phonation outcomes, particularly for those recovering from surgery, nerve injury, or chronic voice strain
- Promotes muscle relaxation and coordination, optimizing voice quality and long-term vocal health
Flexible Endoscopic Evaluation of Swallowing (FEES)
Real-time swallowing function evaluation
- A minimally invasive procedure that evaluates swallowing function in real-time
- Identifies aspiration risks and structural abnormalities that may interfere with safe swallowing
- Assesses swallowing safety and guides personalized therapy plans, including targeted swallowing maneuvers
- Particularly beneficial for patients with post-stroke difficulties, post-surgical changes, post-cancer treatment, or chronic dysphagia, helping restore safe and effective swallowing
Transnasal Esophagoscopy (TNE)
Minimally invasive esophageal examination
- A minimally invasive, transnasal procedure that allows direct examination of the esophagus without sedation
- Detects abnormalities such as reflux, strictures, or lesions early, guiding precise treatment planning

- Guides targeted therapy and interventions to prevent injury, optimize vocal performance, and maintain long-term voice health
Doctor Vox Therapy
Water-resistance voice therapy for easier, healthier voicing
- A semi-occluded vocal tract (SOVT) technique using the Doctor Vox device, developed by Dr. Ilter Denizoglu
- Balances air pressure above and below the vocal folds, so they vibrate with less effort and less impact stress
- Used for vocal fatigue, nodules and muscle tension dysphonia, for rehabilitation after vocal fold surgery, and for warm-ups and voice training
- Delivered by a certified Doctor Vox practitioner, trained in Turkey and Poland under the inventor, with a home exercise programme to follow
Myofascial External Laryngeal Therapy
Hands-on release of tension around the voice box
- A manual therapy that works on the muscles and connective tissue around the larynx and neck
- Releases excess tension that can strain the voice, cause throat tightness or discomfort, and limit vocal range
- Helpful for muscle tension dysphonia, vocal fatigue, a persistent lump-in-the-throat feeling, and voice strain in professional voice users
- Often combined with voice therapy, so better posture and muscle balance carry over into everyday voice use
