Post-Surgery Smell and Taste Loss After Septoplasty: What to Expect - Otolaryngology

Decreased olfactory and gustatory function after septoplasty?


Hello, Doctor.
I underwent a septoplasty at a hospital at the end of April, and since then, my sense of smell and taste has significantly diminished.
I can still somewhat detect scents from products like body wash or shampoo, but I mostly cannot smell regular food and struggle to taste it as well.
Occasionally, there are stronger flavors, but overall, my ability to perceive taste is still much worse than before the surgery.
Typically, the sense of smell and taste are either both present or absent.
I haven't had time to return for a follow-up appointment recently, so I wanted to inquire online about this situation.
Thank you for your assistance.

Hello, if you have only undergone a septoplasty without any additional sinus surgeries or turbinate procedures, it is theoretically unlikely that the surgery would cause long-term loss of smell.
It is recommended to consult an otolaryngologist to check for other potential causes of olfactory dysfunction.
Additionally, taking vitamin B complex may provide some benefit.

Post-surgery smell and taste loss, especially after a procedure like septoplasty, can be concerning for many patients. It’s important to understand the potential causes and what to expect during the recovery process.

Septoplasty is a surgical procedure to correct a deviated septum, which can improve airflow through the nasal passages. While this surgery primarily focuses on the structural aspects of the nose, it can inadvertently affect the olfactory (smell) and gustatory (taste) functions. The loss of smell and taste can be attributed to several factors:
1. Swelling and Inflammation: After surgery, the nasal passages may be swollen and inflamed. This can temporarily obstruct the olfactory receptors located in the nasal cavity, leading to a diminished sense of smell. Since taste is closely linked to smell, this can also affect how food tastes.

2. Nasal Congestion: Post-operative nasal congestion is common and can further impair the ability to smell and taste. If the nasal passages are blocked, it can prevent odor molecules from reaching the olfactory receptors.

3. Nerve Damage: Although rare, there is a possibility of damage to the olfactory nerves during surgery. This could lead to a more prolonged loss of smell and taste. However, most patients do not experience significant nerve damage.

4. Mucosal Healing: The nasal mucosa takes time to heal after surgery. During this healing process, patients may experience changes in their sense of smell and taste. It’s not uncommon for these senses to fluctuate during recovery.

5. Psychological Factors: Sometimes, anxiety or stress related to the surgery and recovery can also impact taste and smell perception.
In your case, since you are experiencing a noticeable decrease in both smell and taste, it is advisable to monitor your symptoms closely. Here are some recommendations:
- Follow-Up Appointment: It’s crucial to schedule a follow-up appointment with your ENT specialist as soon as possible. They can assess your nasal passages for any residual swelling, scarring, or other issues that may be contributing to your symptoms.

- Nasal Irrigation: Using a saline nasal spray or performing nasal irrigation can help clear out mucus and reduce congestion, potentially improving your sense of smell and taste.

- Dietary Adjustments: While your sense of taste is diminished, try to maintain a balanced diet. Experimenting with different flavors and textures may help stimulate your taste buds.

- Patience: Recovery can take time. Many patients find that their sense of smell and taste gradually improves over weeks to months as the nasal passages heal and inflammation subsides.

- Olfactory Training: Some studies suggest that olfactory training—exposing yourself to different scents regularly—can help improve your sense of smell over time.

In conclusion, while it is not uncommon to experience changes in smell and taste after septoplasty, it is essential to keep an open line of communication with your healthcare provider. They can provide tailored advice and interventions to help you recover your senses. If your symptoms persist or worsen, further evaluation may be necessary to rule out any underlying issues.

Dr. Li Jiaxuan reply Otolaryngology
