Understanding and Preventing Chronic Sinusitis: Expert Advice
Hello everyone, I am Dr. Sarah Lim Wei Ling, an ENT specialist with over 15 years of experience in Singapore. I have seen countless patients struggle with chronic sinusitis, a condition that not only causes daily discomfort but also severely impacts their quality of life. Chronic sinusitis, also known as chronic rhinosinusitis (CRS), is a long-term inflammation of the sinuses, usually lasting more than 12 weeks despite treatment. According to the Singapore Society of Otolaryngology - Head and Neck Surgery in 2023, about 10-15% of the Singapore population is affected by CRS, which is similar to the global report from the World Health Organization (WHO), which estimates that CRS affects 5-12% of the adult population worldwide. These numbers are not just statistics; They represent real-life stories that I have encountered at Mount Elizabeth and Gleneagles Hospitals. Today, I would like to share my expertise to help you better understand CRS, its prevention and treatment, in the hope of bringing comfort and hope to your health journey.
Causes and symptoms of chronic sinusitis
Chronic sinusitis often arises from a combination of factors such as bacterial infections, allergies, nasal polyps, or structural problems such as a deviated nasal septum. According to a study published in The Lancet Respiratory Medicine in 2022, about 60% of CRS cases are related to allergies, while 30% have polyps. In Singapore, with its humid tropical climate, mould and dust are common triggers, increasing the risk by up to 20% compared to drier areas (data from Singapore Ministry of Health, 2023).
Typical symptoms include persistent nasal congestion, runny nose, facial or head pain, loss of smell, and even chronic cough due to mucus backflow. I remember a patient at Mount Elizabeth, a 45-year-old office worker, who initially thought his nasal congestion was just due to seasonal allergies. After an endoscopy, we discovered large nasal polyps, leading to CRS. Such cases highlight the importance of early diagnosis, as if left untreated, CRS can lead to serious complications such as infection spreading to the eyes or brain, although rare (less than 1%, according to the Journal of Allergy and Clinical Immunology, 2021).
My practical experience
During my 5 years at Mount Elizabeth Hospital (2015-2020), I performed more than 200 Functional Endoscopic Sinus Surgery (FESS) cases, helping patients remove polyps and improve sinus drainage. One of the biggest lessons learned is the combination of accurate diagnosis and patient education. At Gleneagles, where I have been the Head of the Paediatric ENT Group since 2020, I have developed a CRS screening programme for children, as children make up 20-30% of cases in Singapore (data from local research in Singapore Medical Journal, 2023). One memorable case was an 8-year-old girl with CRS due to milk allergy, diagnosed through endoscopy and allergy testing. After treatment, she no longer had to miss school regularly due to headaches. These experiences reinforce my philosophy: Treatment is not just about curing the disease, but also about empowering patients to understand and manage their condition.
Treatment and prevention
Treatment of CRS usually begins with conservative therapy, including saline irrigation and corticosteroid sprays such as fluticasone. According to the 2020 American Academy of Otolaryngology - Head and Neck Surgery (AAO-HNS) guidelines, this method is effective in 70% of early-stage cases. If it does not respond, endoscopic surgery is the next option, with a success rate of up to 85-90% (study in Otolaryngology - Head and Neck Surgery, 2022). I often recommend patients combine it with allergy management, such as avoiding exposure to dust or using an air purifier.
For prevention, maintain daily nasal hygiene, especially in Singapore's climate. Staying hydrated, avoiding smoking, and getting regular allergy tests are simple but effective steps. A 2023 study from the National University of Singapore (NUS) found that people who irrigated their noses daily reduced their risk of CRS recurrence by 40%. I always advise patients: "Listen to your body; a little stuffy nose can be a big sign."
