Post-Nasal Laser Surgery: Unusual Taste and Smell Issues

Olfactory issues after nasal turbinate laser treatment?

Hello, Doctor.
I underwent laser surgery on my nasal turbinates on March 18.
During this period, I only experienced a loss of smell for the first two days, and no other symptoms occurred.
However, about a week ago, I started tasting strange flavors when eating meat and drinking cola, which have a somewhat disinfectant-like taste, while other foods taste normal.
Additionally, I do not detect any unusual odors when smelling with my nose.
I returned to the hospital for a follow-up today, and the doctor did not find any issues.
After debridement, he only mentioned that there are still some scabs in my right nostril that have not completely healed, along with symptoms of post-nasal drip.
I would like to ask the doctor if this strange taste could be caused by incomplete healing inside my nose.
Will it resolve on its own? Thank you for your response.

Hello, general nasal turbinate laser surgery typically does not affect the olfactory nerves.
It is advisable to observe the situation until the nasal crusting decreases and the wounds heal, and then assess whether the sense of smell returns to normal.
However, if the sense of smell continues to feel abnormal for more than two to three weeks post-surgery, it is important to continue follow-up visits with an otolaryngologist for examination and treatment.

More Info

Post-nasal laser surgery can lead to various changes in taste and smell, which can be concerning for patients. Your experience of unusual tastes, particularly with specific foods like meat and cola, alongside a sensation reminiscent of disinfectant, is not uncommon in the postoperative period.
After nasal surgery, especially procedures like laser surgery for turbinate reduction, the nasal passages undergo significant healing processes. During this time, the mucosal lining, which plays a crucial role in both taste and smell, can be temporarily altered. The presence of crusting or scabs in the nasal cavity, as you mentioned, can also affect olfactory function. When the nasal passages are not fully healed, it can lead to a distorted perception of taste and smell, known as dysgeusia and parosmia, respectively.

The fact that you experienced a loss of smell initially and now have specific taste distortions suggests that your olfactory system is still recovering. The healing process can take several weeks to months, and during this time, it is not unusual for patients to experience fluctuations in their sensory perceptions. The crusting you mentioned can trap odors and affect how smells are perceived, potentially leading to the strange taste sensations you are experiencing.

Regarding your question about whether these issues will resolve on their own, it is likely that as your nasal passages continue to heal and any remaining crusting is resolved, your taste and smell should gradually return to normal. However, this process can vary from person to person. It is essential to maintain follow-up appointments with your ENT specialist to monitor your recovery and address any ongoing symptoms.

In addition to the physical healing, it may be beneficial to consider other factors that can influence taste and smell. For instance, smoking, allergies, and even certain medications can impact these senses. If you are a smoker, reducing or quitting smoking can significantly improve your olfactory function over time.

If your symptoms persist beyond the expected healing period or worsen, it is crucial to consult your ENT specialist again. They may recommend further evaluation, such as imaging studies or additional treatments, to ensure that there are no underlying issues contributing to your symptoms.

In summary, the unusual taste and smell issues you are experiencing after your nasal laser surgery are likely related to the healing process and the presence of crusting in your nasal passages. With time and proper care, these symptoms should improve. However, ongoing communication with your healthcare provider is essential to ensure a smooth recovery and address any concerns you may have.
