Unilateral tonsillar enlargement?


Hello, Doctor.
About three to four months ago (March 109), I noticed that one side of my tonsil was particularly swollen.
At that time, I didn't have any obvious discomfort, so I delayed seeking medical attention until a few days ago (June 25).
During this period, I haven't experienced any significant symptoms (such as unilateral headache, unilateral ear pain, or abnormalities in taste or smell).
My weight has remained stable, and my appetite is normal; I only have discomfort on one side of my throat.
When I visited a nearby clinic, the physician examined my neck and found no lumps.
The doctor also performed an endoscopy and mentioned that I have mild sinusitis causing post-nasal drip, along with severe deviation of my nasal septum leading to inflammation of the tonsil.
However, after taking medication, the swelling did not subside.
Should I go to a major hospital for a biopsy? I am concerned because I used to smoke for a few years, occasionally stay up late, and often drink cold beverages.
Here is a recent picture of my tonsil: https://drive.google.com/file/d/1EHlmkfeXaGQtQLrm2OGDgjtYT10swUX9/view?usp=sharing

Hello: Upon initial examination, the right side appears slightly larger, but there are no obvious tumors or ulcers.
If there are no significant symptoms and a physician has already evaluated the condition, self-monitoring may be appropriate, or a follow-up examination can be scheduled in three months.
Wishing you safety and health.
Sincerely, Dr.
Cheng Jue-Yi, Director of the Department of Otolaryngology, Taoyuan General Hospital, Ministry of Health and Welfare.

Unilateral tonsil swelling can be a concerning symptom, especially when it persists over several months without significant improvement. In your case, the swelling has been present for three to four months, and while you have not experienced severe symptoms such as unilateral headaches, ear pain, or changes in taste or smell, the fact that the swelling has not resolved after treatment is noteworthy.

The initial assessment by your physician, which indicated that the swelling might be due to mild sinusitis and a deviated septum, is a reasonable explanation. Sinusitis can lead to post-nasal drip, which may irritate the tonsils and cause inflammation. However, the lack of improvement after medication raises questions about the underlying cause of the tonsil swelling.

Given your history of smoking and occasional late nights, it is understandable to be concerned about potential malignancies, especially since smoking is a known risk factor for various head and neck cancers. While the absence of significant symptoms is reassuring, it does not entirely rule out the possibility of a more serious condition.

In terms of next steps, it is advisable to consider further evaluation. A biopsy may be warranted to rule out any malignancy, especially if the swelling persists or worsens. A referral to an otolaryngologist (ENT specialist) would be appropriate, as they can perform a thorough examination and determine if a biopsy is necessary. They may also consider imaging studies, such as a CT scan, to assess the tonsil and surrounding structures more comprehensively.

It is important to address your concerns proactively. While many cases of unilateral tonsil swelling are benign and related to infections or inflammation, the duration and lack of response to treatment in your case warrant further investigation. Early detection is crucial, particularly if there is any potential for malignancy.

In summary, while your symptoms may be related to sinus issues, the persistence of the tonsil swelling without improvement suggests that further evaluation is necessary. Consulting with an ENT specialist for a possible biopsy and additional imaging would be a prudent course of action. This will help ensure that any serious conditions are ruled out and that you receive appropriate treatment based on a definitive diagnosis.
