Hello,
I am Prof. Dr. Mehmet Şenoğlu, a Neurosurgery specialist. In my daily practice, the questions I hear most often from my patients and their relatives are usually these: “Doctor, what is the risk of this surgery?”, “What awaits us after the operation?”, “Will I be able to be like I was before?”
In fact, the medical-world counterpart of all these questions—which our patients ask out of justified concern—is the concept of “morbidity.” The word may sound a little foreign, technical, and even frightening. Yet once the medical jargon is set aside, it carries a perfectly understandable meaning that you absolutely need to know for the sake of your own health.
In this article, without drowning in medical terms, I will explain in everyday language what morbidity is and why it carries vital importance.
What Exactly Is Morbidity?
Morbidity refers to the capacity of a disease or an applied treatment process to “make a person ill, cause discomfort, or result in loss of function.”
To summarize it briefly, morbidity is a measure that shows how frequently the troubles, pains, movement restrictions, memory problems, or temporary/permanent loss of strength that may arise after an illness or operation actually occur. It absolutely does not mean “death”; the term that expresses the death rate is “mortality.” Morbidity, rather, is the answer to this question: “You survive, but how much and for how long is your quality of life affected by this condition?”
Let’s give a concrete example. Suppose you undergo brain tumor surgery. You come through the operation without complications and the tumor is successfully removed (that is, the mortality/death risk does not materialize). However, for the 3–4 weeks following the surgery, you experience headaches, temporary weakness in your arm, or a mild memory problem. This recovery process you go through and the temporary difficulties you experience are precisely part of the picture of morbidity.
Why Is Morbidity So Important in Neurosurgery?
Our brain is, without doubt, the most delicate and complex organ of the human body. Because every surgical intervention inevitably requires contact with nervous tissue, it carries with it a certain risk of morbidity (functional impact).
But here we have good news: thanks to the point modern medicine and technology have reached, we can now reduce these risks to a very significant degree.
Thanks to microsurgery and neuronavigation technologies, we can reach the lesion or tumor in the brain with millimetric precision, without damaging the surrounding tissues. With intraoperative neuromonitoring, by monitoring the critical regions of the brain in real time and electrically during the operation, we can prevent possible nerve damage before it even occurs. In awake brain surgery, particularly for tumors near the speech and movement centers, we keep our patient awake while performing the surgical procedure, thereby reducing functional losses (morbidity) to a minimum.
Today, in well-equipped centers and in experienced hands, the permanent morbidity rate in operations such as meningioma, pituitary adenoma, or low-grade glioma is on average around 2–5%. In other words, roughly 95–98 out of every 100 patients are able to return healthily to their daily, normal lives in the post-operative period.
Do Not Confuse Morbidity with Mortality
There is a dialogue I encounter very often in my practice. The patient, with justified concern, asks: “Doctor, what is the risk of dying on the table during this surgery?”
My answer to this question is usually as follows: “Under today’s conditions, the risk of death (mortality) is extremely low; the real issue we need to focus on and discuss is the functional risks—that is, morbidity.” Because in modern neurosurgery, the fundamental goal is not merely to keep the patient alive, but to be able to offer them the highest quality of life when they wake up.
What Should You Do as a Patient or a Patient’s Relative?
Before making the decision to operate, establish open communication by discussing the entire process transparently with your doctor. Do not hesitate to ask the right questions: queries such as “What complaints most commonly arise after this surgery?”, “How long does the recovery process take?”, and “Is there a risk of temporary or permanent damage?” help you understand every dimension of the process. To set your mind at ease, obtaining a second opinion from a different specialist is your most natural right. Finally, do not postpone rehabilitation; starting the recommended rehabilitation programs early after surgery (physiotherapy, speech therapy, or neuropsychological support) is the most powerful way to minimize the effects of morbidity.
Final Word
Morbidity is not a word you should fear when you hear it; on the contrary, it is a highly valuable compass that enables you to make informed decisions about your own health.
The greatest aim of us neurosurgeons is not merely to keep our patients alive, but to preserve and improve their quality of life and ensure they spend healthy years with their loved ones. If you or someone close to you is experiencing a health problem related to brain and nerve surgery, you can contact our clinic to evaluate your situation and answer your questions in detail.
Stay well…
