You have had blocked sinuses and recurring infections for the better part of a year. Your GP has put you through two courses of antibiotics and a steroid nasal spray. Your general ENT specialist referred you for a CT scan, found some findings, and suggested surgery. But your symptoms persist or later return.
At some point in that journey, the question becomes: do I need a more focused assessment of my nose and sinus condition? That is where rhinology comes in. A rhinologist is an ENT surgeon who has completed a subspecialty fellowship specifically in diseases of the nose, sinuses, and anterior skull base.
The additional training involves focused experience in complex nasal and sinus conditions, including chronic rhinosinusitis with nasal polyps, revision sinus surgery, skull base conditions, and infections that may persist despite standard treatment. This guide covers what that training difference means in practice, which conditions most benefit from it, how to verify subspecialty training, and what to bring to a focused rhinology consultation.

The rhinology subspecialty becomes relevant when the problem is complex, recurring, or has already gone through standard treatment without sustained relief.
What Is a Rhinologist?
All rhinologists are ENT specialists, although not all ENT specialists practise rhinology as a subspecialty area. An ENT specialist (otolaryngologist) is trained to manage conditions across the full ear, nose, throat, head and neck. That is a significant scope of anatomy, which is why many ENT surgeons eventually develop a deeper focus in one specific area through further fellowship training.
A rhinologist in Singapore has completed that additional fellowship in rhinology, the subspecialty focused on the nose, sinuses, and anterior skull base. This typically involves 12–24 months of concentrated work at a specialist tertiary centre, managing complex sinonasal and skull base cases. In practical terms, additional fellowship exposure may include:
Revision Sinus Surgery
Volume and complexity of revision cases where prior surgery has altered the normal anatomy.
Image-Guided Navigation
Familiarity with intraoperative navigation systems used in complex and revision sinus surgery.
Complex Inflammatory Disease
Experience with severe nasal polyposis, aspirin-exacerbated respiratory disease (AERD), and CSF leaks.
Multidisciplinary Links
Established pathways with allergists, pulmonologists, neurosurgeons, and radiologists for cross-boundary cases.
Many straightforward ENT conditions can be assessed and managed within general ENT practice. The rhinology subspecialty becomes relevant when the problem is complex, recurring, or has already gone through at least one round of standard treatment without sustained symptom control.

Rhinologist & General ENT Specialist: Different Areas of ENT Practice
What Fellowship Training Actually Means
The word "fellowship" appears on a lot of specialist profiles. A rhinology and skull base surgery fellowship is an additional 12–24 months of supervised training after completing an ENT specialist degree. Fellows work at specialist tertiary centres where complex sinus and skull base cases are concentrated, building focused experience beyond core ENT residency training. Areas commonly covered include:
- Endoscopic sinus surgery with mucosal-sparing technique — restoring ventilation and mucociliary clearance while preserving normal function where appropriate.
- Image-guided navigation systems for complex and revision cases where prior surgery has disrupted normal anatomic landmarks.
- Endoscopic skull base surgery — CSF leak repair, skull base tumour resection, and co-ordination with neurosurgery.
- Subspecialty management of severe nasal polyposis and AERD, including use and monitoring of biologic therapies.
- Revision sinus surgery strategy — managing anatomy altered by previous procedures, including scarring from prior surgery.
Fellowship training also includes research and teaching responsibilities. A rhinologist who continues to publish and teach remains engaged with evolving evidence, particularly relevant in biologic therapy, where guidance has changed significantly over the last five years.
- Dr Gan Eng Cern completed his rhinology and skull base surgery fellowship at St Paul's Sinus Centre, University of British Columbia, Vancouver, Canada.
- The fellowship was supported through the Health Manpower Development Programme (HMDP) Award from the Ministry of Health, Singapore.
- Before entering private practice, Dr Gan served as Deputy Director of the Rhinology Service at Changi General Hospital (2013–2017).
- He is a Senior Clinical Lecturer at the NUS Yong Loo Lin School of Medicine and has published in peer-reviewed international ENT journals.
Conditions That Benefit Most From Rhinology Subspecialist Care
The following conditions form the core of rhinology subspecialty practice — conditions that are commonly referred for rhinology assessment.
Chronic Rhinosinusitis (CRS)
The approach varies with whether nasal polyps are present, the inflammatory phenotype, comorbid asthma, and prior treatment. Individualised planning and consistent follow-up support symptom management.
Recurrent or Refractory Sinusitis
When infections return despite appropriate antibiotics, rhinologists assess the underlying contributors — anatomic factors, biofilm disease, immune function, and mucosal phenotype — then tailor treatment.
Nasal Polyposis & AERD
Nasal polyposis with asthma and aspirin sensitivity (AERD) requires integrated medical and surgical planning. Biologic therapies have changed management for severe type-2 polyposis.
CSF Leaks & Skull Base Lesions
Endoscopic repair of cerebrospinal fluid leaks — spontaneous, post-traumatic, or post-surgical — and resection of skull base lesions is often managed in subspecialty settings.
Revision Sinus Surgery
If prior sinus surgery did not fully resolve symptoms, revision is a specific challenge. Distorted anatomy, scarring, and residual disease require careful planning and direct experience.
Complex Nasal Obstruction
Deviated septum, turbinate hypertrophy, and nasal valve collapse — in patients with prior surgery the goal is improving airflow and function, not just anatomic correction.
Progressive or Unexplained Smell Loss
Olfactory disorders associated with nasal inflammatory disease require specialist assessment. Where smell loss is progressive or unexplained after initial GP review, rhinology evaluation including objective olfactory testing is appropriate.
When to See a Rhinologist vs a General ENT Specialist
General ENT care is the right starting point for most patients. The question is when subspecialist input adds something specific. Match your situation below.
Considering a Focused Rhinology Assessment?
Subspecialty Techniques in Rhinology Practice
The following are techniques commonly used in subspecialty rhinology practice and may be incorporated into care at Mount Elizabeth Novena Hospital.
Image-Guided Navigation
Navigation systems provide real-time intraoperative orientation relative to pre-operative imaging. They are often used in revision cases where prior surgery has altered anatomic landmarks, and in selected complex primary cases near critical structures.
FESS in Singapore: Endoscopic Sinus Surgery With Mucosal-Sparing Technique
The goal of functional endoscopic sinus surgery (FESS) is to restore sinus ventilation and mucociliary clearance, with attention to preserving normal mucosa where appropriate. Mucosal-sparing techniques aim to minimise post-operative scarring and maintain sinus function. FESS in Singapore may often be performed as a day procedure at MOH-accredited facilities.
Endoscopic Skull Base Surgery and CSF Leak Repair
Endoscopic approaches may be used for repair of anterior skull base defects without external incisions. Where neurosurgical involvement is required, care is typically coordinated through multidisciplinary skull base teams.
Biologic Therapy Integration
For patients with severe type-2 inflammatory nasal polyposis, biologic therapies such as dupilumab have expanded treatment options. Management may include patient selection assessment, coordination with respiratory physicians, and monitoring of treatment response.
Objective Outcome Tracking (SNOT-22)
Validated assessment tools including the SNOT-22 questionnaire and CT staging systems may be used to document baseline disease severity and monitor symptom response over time.
Finding and Verifying a Rhinologist in Singapore
ENT specialists may have different subspecialty training backgrounds depending on their clinical focus. Here are some areas patients may wish to review when seeking rhinology care.
Verify Fellowship Training Specifically
Different ENT fellowships may focus on different subspecialty areas. Patients may wish to review the fellowship centre, duration of training, and clinical focus where available. Specialist registration can also be verified through the Singapore Medical Council (SMC) Register of Medical Practitioners, a public resource.
Check Hospital Privileges and MOH Accreditation
Many endoscopic sinus procedures may be performed in MOH-accredited day surgery facilities, while selected skull base procedures and complex revision cases may require inpatient admission.
Ask About Outcome Data
Rhinology assessment may involve validated tools such as SNOT-22 scoring, endoscopic findings, imaging review, and clinical follow-up to monitor disease severity and symptom response over time.
Review Publication and Teaching Record
Publication and teaching activities may reflect ongoing academic involvement and participation in continuing medical education.
Confirm Multidisciplinary Links
In selected complex cases, management may involve collaboration with allergists, pulmonologists, radiologists, and neurosurgical teams.
- SMC Register registration verified.
- Rhinology or skull base fellowship information available where applicable.
- Hospital practice location and admission arrangements clarified.
- Use of validated symptom assessment tools discussed during consultation.
- Publication or teaching activities listed where applicable.
- Multidisciplinary referral pathways available where needed.
