About Our ENT Clinic in Mount Alvernia Hospital
Located within Mount Alvernia Hospital, our ENT clinic provides a dedicated setting for patients seeking evaluation and treatment for conditions affecting the ear, nose, throat, head, and neck.
We manage a wide range of ENT conditions, from sinus and hearing issues to voice disorders and paediatric ENT concerns, offering care for both adults and children.
The clinic serves patients across Singapore, including those residing near Bishan, Novena, and Thomson Road, who prefer convenient access to ENT consultations within a hospital environment.
Conditions & Treatments Available
Our clinic provides evidence-based assessment and treatment for a broad range of ENT conditions. Management plans are tailored according to each patient’s needs, guided by current clinical guidelines and published medical research.
Paediatric ENT
Children may experience conditions such as ear infections, tonsillitis, nasal obstruction, or sleep-related breathing disorders. Our clinic offers careful assessment and management to support healthy development and comfort in younger patients.
Thyroid
We evaluate and manage thyroid-related neck conditions, including nodules, cysts, and gland enlargement. Where indicated, diagnostic imaging or fine-needle aspiration biopsy may be performed to establish an accurate diagnosis.
Snoring
Snoring may arise from airflow resistance within the upper airway. Assessment involves identifying potential anatomical or lifestyle-related causes, with treatment options ranging from conservative measures to procedural interventions as clinically appropriate.
Sleep Apnea
Sleep apnea is characterised by interrupted breathing during sleep. Evaluation includes discussion of symptoms, potential contributing factors, and diagnostic tests such as sleep studies, in accordance with international sleep medicine guidelines.
Sinusitis
Sinus inflammation may cause nasal congestion, facial pressure, or reduced smell. Medical therapies such as nasal irrigation, topical corticosteroids, and antibiotic treatment are often first-line, while surgery may be considered for persistent or recurrent cases.
Nose Allergy
Nasal allergies, or allergic rhinitis, are managed through avoidance of triggers, pharmacological therapy, and in some cases, immunotherapy. Treatment follows evidence-based recommendations by the Allergy, Asthma & Immunology Association of Singapore.
Sore Throat
A sore throat can result from infections, voice strain, or environmental factors. Management depends on the underlying cause, with treatment guided by ENT evaluation and, if necessary, diagnostic testing such as laryngoscopy or throat swabs.
Deviated Nasal Septum
A deviated nasal septum may cause nasal blockage or recurrent sinus infections. Depending on severity, treatment options range from medical management to surgical correction (septoplasty), performed according to established surgical protocols.
