Today we saw a surgery that we’ll likely never see again. A young man in his early 20’s walked in to the ENT operating theater at Muhimbili National Hospital with a large tumor on his forehead that enveloped his left eye. If you look closely at the X-ray in the top left corner, the extent of the tumor is quite clear.
Judging by how many surgeons and residents were present for the surgery, this kind of tumor is unusual even in ENT. The head surgeon wasn’t sure whether this tumor was caused by cancer, a fungal infection or tuberculosis. A previous biopsy suggested that it was a fungal infection of the sinus – “fungal rhinosinusitis.” The surgery was listed as a “frontal ethmoidectomy,” or a removal of the frontal ethmoid sinuses which are located behind and to the side of the bridge of the nose.
There was some debate as to whether this tumor contained any brain tissue. The surgeon pointed out on the MRI images that there was a clear delineation between the tumor and the patient’s brain – the thin black line between the tumor and brain tissue is called the “dura,” a thick membrane that surrounds the brain.
In any case, the surgeon wanted to operate and remove as much of the tumor as possible and send samples to the lab for closer examination.
Because the tumor had enveloped the patient’s left eye, they had to suture the eye shut for the surgery in order to avoid damaging it. The surgeon made one long horizontal incision through the patient’s forehead and began cutting and scraping away at the tumor inside.
She spent over an hour removing bits of whitish tissue. At one point she called in another surgeon to consult on whether it was safe to scrape away tumor tissue near the back of the patient’s left eye socket.
The operating room was packed with about 16 people at one point and it was hard to find a spot where I could see what was happening. The surgeon jokingly admonished the anesthesiologist for standing too close and preventing residents from seeing the surgery.
The CT scans and MRI images above are dated from spring of 2014. I don’t understand why it took them so long to operate, or why they’re operating now using two-year-old images as a guide. In the meantime, this patient has had to live with a tumor the size of a tennis ball on his forehead. His eye was bulging out of his head and it was hard for him to blink properly.
When the operation was over, the surgeons suspected that this was actually a cancer tumor rather than a fungal infection. It wasn’t clear exactly what this man’s prognosis was, not at least until the pathology lab examined the samples of his tumor. But he’s at least temporarily relieved of the massive tumor that once occupied his forehead and sinuses.
Based on the day’s schedule, I inferred that about half of ENT surgeries consist of removing the tonsils of young children. The case preceding the tumor was an adenotonsillectomy (removal of both the tonsils and the adenoids), as was the case afterwards. We were asked to stay further away from the surgical field when young kids were being operated on because of the higher risk of infections.
I only wish they would have used a camera and turned on the TV screen so we could see the surgeries up close. At least the room was air conditioned – you don’t want surgeons sweating and dripping into the surgical field 😉
