Are services from Dr. Theriault, an Otolaryngologist - Head and Neck Surgeon, covered by Ontario Health Insurance Plan (OHIP) in ON?

Medically necessary consultations, diagnostic tests, and surgical procedures performed by a licensed Otolaryngologist - Head and Neck Surgeon like Dr. Theriault are generally covered by Ontario Health Insurance Plan (OHIP) in ON when you have a valid referral from your family doctor or another referring physician. Some elective or cosmetic procedures may not be covered. It's always recommended to confirm specific coverage details with Ontario Health Insurance Plan (OHIP) or the clinic if you have questions.

Do I need a referral from my doctor to see Dr. Theriault, an Otolaryngologist - Head and Neck Surgeon?

Yes, for services to be covered by your provincial health plan (Ontario Health Insurance Plan (OHIP)), a referral from your family physician or another specialist is typically required to see an Otolaryngologist - Head and Neck Surgeon like Dr. Theriault. This ensures coordinated care. Some clinics may offer non-insured consultations without a referral, but this is not standard for provincially covered services. Please check with the clinic or your referring doctor.

How are allergies related to ENT problems?

Allergies can significantly impact the ears, nose, and throat. Allergic rhinitis (hay fever) can cause nasal congestion, runny nose, sneezing, post-nasal drip, and itchy, watery eyes. Allergies can also contribute to chronic sinusitis, eustachian tube dysfunction (leading to ear pressure, popping, or fluid), recurrent ear infections, and exacerbate conditions like asthma or voice changes. An ENT specialist may investigate and help manage the ENT-related symptoms of allergies, often by recommending nasal sprays, antihistamines, or discussing options like immunotherapy, sometimes working in conjunction with an allergist.

How does Dr. Theriault treat chronic sinusitis?

Treatment for chronic sinusitis is individualized and aims to reduce inflammation, drain the sinuses, and address underlying causes (like allergies or polyps). This may involve medications such as nasal corticosteroid sprays, saline rinses, oral antibiotics (if bacterial infection is confirmed), antifungal treatments in specific cases, or allergy management. In some cases, if medical management is not sufficient, Dr. Theriault may recommend surgical procedures like functional endoscopic sinus surgery (FESS) or balloon sinuplasty to improve sinus drainage and ventilation.

What kind of post-operative care instructions can I expect after an ENT surgery?

Post-operative care instructions will be specific to the type of surgery performed. Generally, they may include information on pain management, diet restrictions (e.g., soft foods after tonsillectomy), activity limitations, wound care (if applicable), use of medications (like antibiotics or pain relievers), nasal saline rinses (after sinus surgery), and signs of potential complications to watch for. You will also be given follow-up appointment details. It's crucial to follow these instructions carefully for optimal healing.
