Dr. Hu Kexin reply Otolaryngology


Hello: There are many reasons that can cause foul-smelling breath, and sinusitis is one of the common causes.
If you experience pain while inhaling through your nose, you should consult a physician for a thorough examination.
Be careful not to blow your nose too forcefully or pick your nose.
The sinuses are air-filled cavities, and if you are unclear about the status of your CT scan, you may need to ask your doctor for a more detailed explanation.

Understanding sinus gasification, particularly in the context of bad breath and nasal pain, involves a multifaceted approach to diagnosing and treating potential underlying conditions. The term "sinus gasification" is not commonly used in medical literature, but it may refer to the presence of gas or air in the sinus cavities, which can be associated with various sinus conditions, including chronic sinusitis or other forms of sinus dysfunction.


Causes of Bad Breath and Nasal Pain
1. Sinusitis: Chronic sinusitis can lead to inflammation and blockage of the sinus cavities, which may result in the accumulation of mucus and bacteria. This can produce foul-smelling breath due to the presence of anaerobic bacteria that thrive in stagnant mucus. Although your CT scan showed no signs of sinusitis, it’s important to consider that sinusitis can sometimes be present without clear imaging findings.

2. Nasal Polyps: These are non-cancerous growths in the nasal passages or sinuses that can obstruct airflow and drainage, leading to pressure and pain. They can also contribute to bad breath by trapping mucus and bacteria.

3. Dental Issues: Conditions such as gum disease or dental abscesses can also cause bad breath and may refer pain to the nasal area. If you have ongoing dental issues, it may be worthwhile to consult a dentist to rule out any oral health problems.

4. Gastroesophageal Reflux Disease (GERD): This condition can lead to bad breath due to the backflow of stomach acids into the esophagus and mouth, which can also cause throat irritation and pain.

5. Allergies: Allergic rhinitis can lead to nasal congestion and postnasal drip, which may result in bad breath and discomfort in the nasal passages.


Nasal Pain During Inhalation
The pain you experience when inhaling could be attributed to several factors:
1. Nasal Mucosa Irritation: If the lining of your nasal passages is inflamed or irritated, inhaling can exacerbate the discomfort. This can occur due to allergies, irritants in the environment, or even dry air.

2. Sinus Pressure: If there is any blockage or inflammation in the sinuses, it can create pressure that is felt during inhalation. This is often described as a sharp or dull pain in the nasal area or forehead.

3. Structural Abnormalities: Deviated septum or other anatomical variations can lead to uneven airflow and pressure in the nasal passages, causing pain during inhalation.


Recommendations for Further Evaluation
Given your symptoms and the complexity of your condition, it may be beneficial to pursue further evaluation:
1. ENT Specialist Consultation: A visit to an Ear, Nose, and Throat (ENT) specialist can provide a more thorough examination of your nasal passages and sinuses. They may recommend a nasal endoscopy to visualize the nasal cavity and sinuses directly.

2. Allergy Testing: If allergies are suspected, testing can help identify specific triggers that may be contributing to your symptoms.

3. Dental Evaluation: Since bad breath can often be linked to dental issues, a comprehensive dental check-up is advisable.

4. Consider Imaging Studies: If symptoms persist, further imaging studies, such as a repeat CT scan or MRI, may be warranted to assess for any changes or new developments in the sinuses.

5. Hydration and Humidification: Keeping well-hydrated and using a humidifier can help alleviate nasal discomfort and improve mucus drainage.

In summary, the combination of bad breath and nasal pain can stem from various causes, including sinus issues, dental problems, or allergies. A comprehensive approach involving specialists from different fields may be necessary to pinpoint the exact cause and develop an effective treatment plan.
