Does a Nabothian cyst require treatment?

Nabothian cysts (also known as cervical glandular cysts) are benign cystic lesions formed when the openings of cervical gland ducts become narrowed or obstructed, impeding the normal drainage of glandular secretions and leading to their accumulation within the glands. The vast majority of Nabothian cysts represent physiological changes of the cervix. Typically asymptomatic, they are most often discovered incidentally during routine gynecological examinations. Chronic inflammation may cause repeated cervical tissue congestion, edema, inflammatory cell infiltration, and fibrous connective tissue proliferation—ultimately resulting in cervical hypertrophy. So, do Nabothian cysts require treatment? Below, we address this question.

Do Nabothian Cysts Require Treatment?

Under normal conditions, numerous mucous glands are distributed throughout the cervix. Secretions from these cervical mucous glands naturally drain through the glandular orifices, helping to lubricate and protect the vagina. In cases of chronic cervicitis, however, the ductal openings of cervical mucous glands may become covered and obstructed by newly formed squamous epithelial cells, preventing secretion drainage and causing retention within the glands—thus forming cervical cysts, commonly referred to as Nabothian cysts. Like cervical polyps, Nabothian cysts are a manifestation of chronic cervicitis and are among the most common gynecological conditions. Most Nabothian cysts are small, solitary, or scattered, and remain clinically asymptomatic. If cervical cancer screening results (e.g., Pap smear and/or HPV testing) are normal, no specific treatment is required.However, some patients may experience symptoms such as increased vaginal discharge—often thick, malodorous, or accompanied by postcoital bleeding or blood-tinged leukorrhea—in which case treatment is warranted.

Knowledge Extension: What Causes Nabothian Cysts?

1. Infection

Gynecological infections are commonly treated using various approaches—including surgery, which is frequently employed. Although surgical intervention can effectively resolve gynecological inflammation, bacterial infection or other complications during the procedure may predispose to cyst formation. For instance, multiple induced abortions may cause cervical trauma, thereby increasing the risk of Nabothian cyst development.

2. Glandular Duct Obstruction

Normally, squamous and columnar epithelia of the cervix undergo dynamic transformation at their junction—the squamocolumnar junction (SCJ). The replacement of columnar epithelium by squamous epithelium is termed “squamous metaplasia.” During this process, newly formed squamous epithelium may cover the openings of cervical gland ducts or extend into the ducts themselves, thereby obstructing them. This obstruction impedes the outflow of glandular secretions, leading to their retention and subsequent cyst formation.

3. Inflammation

Local cervical injury or chronic cervical inflammation may cause narrowing of gland duct orifices, contributing to the development of cervical glandular cysts. Nabothian cysts may occur in isolation or coexist with other gynecological conditions. Untreated chronic cervicitis, for example, may progress to or be associated with Nabothian cyst formation.

The above provides an overview addressing whether Nabothian cysts require treatment. We hope this information is helpful to you.
