The internal os is the inner opening of the cervix that connects the uterus to the cervical canal. Injuries to this area can occur from childbirth, medical procedures, accidents, or infections. In this guide, we explain what an internal os injury is, its structure and function, different types, possible causes, symptoms you may notice, tests that help diagnose the injury, treatment options (both non‐pharmacological and pharmacological), surgical options, prevention tips, and when you should see a doctor. We also answer common questions in a FAQ section.
Internal Os of the Uterus Injury refers to damage or trauma affecting the internal os—the narrow, muscular opening at the top of the cervix. This injury may result in structural changes (such as tears or scarring), which can affect the normal functioning of the cervix. The cervix plays a key role in reproductive health by regulating the passage between the uterus and the vagina, and any injury can affect menstrual flow, fertility, and the ability to maintain a pregnancy.
Key points:
- Location: The internal os is located deep within the cervix.
- Function: It helps control the opening and closing of the cervix during menstruation, sexual intercourse, and childbirth.
- Injury Impact: Damage may lead to pain, bleeding, or complications in future pregnancies.
Pathophysiology
Understanding how an internal os injury develops requires knowing a bit about its structure, blood and nerve supply, and functions.
Structure
- Cervical Anatomy: The cervix is composed of a fibromuscular tissue that includes the internal os (upper part) and the external os (lower part). The internal os acts as a valve-like structure.
- Smooth Muscle and Connective Tissue: This area is made of smooth muscle and connective tissue that allows it to open and close during different phases of the reproductive cycle.
Blood Supply
- Uterine Artery: Blood to the cervix, including the internal os, is mainly provided by the uterine arteries. Adequate blood flow is essential for tissue repair and function.
- Collateral Vessels: Other nearby vessels help maintain the blood supply if the primary vessels are compromised.
Nerve Supply
- Pelvic Splanchnic Nerves: These nerves provide sensation and control the smooth muscle contraction in the cervix.
- Autonomic Regulation: The sympathetic and parasympathetic nervous systems work together to regulate the function of the internal os, especially during labor and menstruation.
Functions
- Cervical Barrier: The internal os helps protect the uterus from infections by acting as a barrier between the vagina and the sterile uterine environment.
- Regulation of Passage: It controls the passage of menstrual blood from the uterus to the vagina and helps keep the uterus closed during pregnancy.
- Role in Childbirth: During labor, the internal os dilates (opens) to allow the baby to pass through the birth canal.
Types of Internal Os Injuries
Internal os injuries can vary in severity and nature. Here are several types:
- Laceration: A tear in the tissue caused by trauma.
- Abruption: Partial separation of tissue layers.
- Scar Formation: Resulting from previous injury or surgery.
- Iatrogenic Injury: Damage caused by medical procedures (e.g., dilation and curettage, cervical cerclage placement).
- Traumatic Injury: Injury due to accidents or falls.
- Infection-Induced Injury: Damage from severe or chronic infections.
- Ischemic Injury: Reduced blood supply causing tissue damage.
- Inflammatory Injury: Chronic inflammation leading to tissue changes.
- Radiation Injury: Tissue damage following radiation therapy.
- Degenerative Changes: Age-related weakening of the cervical tissue.
