Does a maxillary sinus retention cyst require surgical treatment?


A health check revealed a 1 cm retention cyst in the left maxillary sinus.
Is there a way for it to shrink or disappear on its own, or is surgical removal necessary?

Ricky Chou, 30~39 year old female. Ask Date: 2021/09/29

Dr. Zheng Jueyi reply Otolaryngology


Hello: If there are no obvious symptoms in the nose, self-observation is sufficient, and surgery is not necessary.
If symptoms are present, medication treatment generally has poor efficacy, and surgical intervention is recommended.
Wishing you peace and good health.
Sincerely, Dr.
Cheng Jue-Yi, Director of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

More Info


Maxillary sinus retention cysts are relatively common findings on imaging studies, often discovered incidentally during routine health check-ups. These cysts are typically benign, fluid-filled sacs that develop in the maxillary sinus, and they are usually asymptomatic. The question of whether they require surgical treatment depends on several factors, including the size of the cyst, the presence of symptoms, and any associated complications.

In most cases, maxillary sinus retention cysts do not require surgical intervention, especially if they are small (like the 1 cm cyst you mentioned) and asymptomatic. Many of these cysts can remain stable over time or may even resolve spontaneously without any treatment. The body's natural processes can sometimes lead to the reduction in size or complete disappearance of these cysts.
However, if the cyst is causing symptoms such as facial pain, pressure, nasal obstruction, or recurrent sinus infections, then surgical treatment may be considered. The most common surgical procedure for symptomatic maxillary sinus cysts is functional endoscopic sinus surgery (FESS), which allows for direct visualization and access to the sinus cavity. During this procedure, the cyst can be removed, and any underlying issues contributing to sinus problems can be addressed.

It's important to note that the decision for surgery should be made in consultation with an otolaryngologist (ENT specialist) who can evaluate your specific situation. They will consider your medical history, the cyst's characteristics, and any symptoms you may be experiencing. Imaging studies, such as a CT scan, may also be utilized to assess the cyst and the surrounding sinus anatomy more thoroughly.

In summary, maxillary sinus retention cysts do not always require surgical treatment. If the cyst is small and asymptomatic, observation may be the best approach. However, if you experience symptoms or complications, surgical intervention may be warranted. Always consult with a healthcare professional for personalized advice and treatment options based on your individual circumstances.
