Ear, Nose, Throat (ENT) Conditions We Treat &
Services We Provide

Nasal Allergy / Allergic Rhinitis

Allergic conditions such as allergic rhinitis and ‘sinus’ are some of the most common complaints in this day and age. Problematic allergies can affect one’s quality of life.

Sinus Conditions

Our sinuses help humidify and heat the air that we breathe; and produce mucous which helps protects the nose from pollutants, micro-organisms, dust and dirt. 

Snoring & Obstructive Sleep Apnoea

Snoring is one of the most common complaints that bed partners report. Not only is snoring a nuisance, but up to 75% of snorers have some degree of Obstructive Sleep Apnea (OSA) which may lead to general health complications in the long-term.

Paediatric ENT

Paediatric ENT looks after infants and children, who are often unable to relate their symptoms accurately. They may be irritable, refuse to feed, constantly rub their noses or pick at their ears.

Voice, Throat & Swallowing

As the primary means of communication, our voice plays an important role in daily life. It conveys information such as our emotional state and personal traits. 

Ear, Hearing Loss & Audiology

As one of our most important senses, the ability to hear enables us to connect to the world and people enabling us to communicate in a way that none of our other senses can achieve.

Vertigo, Dizziness & Balance

The ear is a remarkable organ which is not only responsible for our hearing, but also keeps us in equilibrium. Conditions which affect the ear may result in vertigo, dizziness, or hearing and balance disorders.
