Should I Seek Medical Attention After Nasal Swab Mishap?

I would like to ask Dr. Jiang whether this situation requires medical attention or if it can be monitored further. Thank you?

Hello, Doctor Jiang.
I recently had contact with a confirmed case, and during a rapid test, I mistakenly inserted the swab stick 11 centimeters into my nostril while my eyes were closed.
I didn't feel any pain during the process, but afterwards, I started to feel a bit dizzy and realized something might be wrong.
Doctor, did I poke into my brain? Will there be any long-term effects? Should I make an appointment for an immediate consultation, or can I just observe my symptoms for now? I visited a nearby pediatric clinic, but the doctor couldn't provide any advice.
I really did measure it at 11 centimeters.
Thank you for taking the time to respond.

Dear Ms.
Chang,
You mentioned that "an operational error led to the rapid test swab being inserted 11 centimeters into the nostril," which likely means it passed through the nasal turbinates and reached the oropharynx.
Our nasopharynx contains bone, and unless there has been a recent severe head injury causing a skull base fracture, it is unlikely for anything to enter the brain from the nasal cavity.
Please do not worry.
Clinically, a nasogastric tube is typically inserted 50-60 centimeters.
The length of the nasopharynx is approximately from the tip of the nose to the earlobe.
Thank you for your inquiry, and feel free to discuss any related questions!
Wishing you good health and peace,
Dr.
Jiang Junyi, Taoyuan Hospital

More Info

It sounds like you had a concerning experience with the nasal swab, and it's understandable to feel anxious about the potential consequences. Let's break down your situation and address your concerns.

Firstly, the nasal cavity is approximately 12 to 15 centimeters long, and while it is possible to insert a swab deep into the nasal passage, it is unlikely that you reached the brain. The brain is protected by several layers, including the skull and the meninges, which are tough membranes that encase the brain and spinal cord. A nasal swab, even if inserted deeply, typically does not penetrate these protective barriers unless there is a pre-existing condition or significant trauma.

However, inserting a swab too deeply can cause irritation or injury to the nasal mucosa, which may lead to symptoms such as bleeding, pain, or infection. The fact that you did not experience immediate pain during the procedure is somewhat reassuring, but the subsequent dizziness and discomfort are worth noting. Dizziness can sometimes be a result of anxiety or a vasovagal response, especially if you were worried about the procedure itself.

Given your symptoms and the depth of the swab insertion, it is advisable to seek medical attention. Here are a few reasons why:
1. Assessment of Injury: A healthcare professional can examine your nasal passages to check for any signs of trauma or bleeding. They may use a nasal endoscope to visualize the area more clearly.

2. Monitoring for Complications: While serious complications are rare, it is important to monitor for any signs of infection or other issues that may arise from the swab insertion. Symptoms to watch for include persistent pain, bleeding, or discharge from the nose.

3. Dizziness Evaluation: Your dizziness may or may not be related to the swab incident. A healthcare provider can help determine if it is a result of anxiety, a reaction to the procedure, or something that requires further investigation.

4. Peace of Mind: Consulting with a medical professional can provide you with reassurance and clarity about your situation. They can address your concerns and help you understand what to expect moving forward.

In summary, while it is unlikely that you have caused significant harm by inserting the swab 11 centimeters into your nasal cavity, it is still important to have a medical evaluation to rule out any potential issues and to address your symptoms. It is always better to err on the side of caution when it comes to health concerns, especially when there is uncertainty about a procedure's impact. If you experience worsening symptoms or new concerns, do not hesitate to seek immediate medical attention.
