BETHESDA, Md.  –   For 15 years, U.S. Marine Staff Sgt. Andy Archer lived with a relentless, everyday companion — a pounding headache.

“I’d wake up with a headache and go to bed with a headache,” Archer recalled. He chalked it up to severe allergies or sinus issues, relying on over-the-counter decongestants to get through his demanding days.

Archer is a former drill instructor on Parris Island, South Carolina, and a current flightline mechanic at Marine Corps Air Station New River at Camp Lejeune, North Carolina. Because of the headaches, pushing through the pain became part of his daily routine. But recently, Archer’s vision began to blur.

“I became nearsighted, it was bad, I thought I was getting old!” Archer said. He finally mentioned the chronic pain to his doctor, a provider with Marine Centered Medical Home New River.

The doctor ordered an MRI for Archer that revealed a mass the size of a golf ball, measuring roughly 4.4 centimeters sitting directly in front of his pituitary gland and pressing against his optic nerve.

Archer needed neurological care, and he needed it fast. It was suggested that he go to the premier medical hub for complex cases: Walter Reed National Military Medical Center.

At Walter Reed, Archer consulted with Skull Base Neurosurgeon U.S. Army Lt. Col. (Dr.) Charles “Chip” Miller and Skull Base Rhinology and Anterior Surgeon U.S. Army Maj. (Dr.) J. Patel. The specialized surgical team mapped out an innovative, minimally invasive procedure known as an endonasal endoscopic approach.

The surgeons planned to extract the massive brain tumor entirely through Archer's nose. “Historically, most of these surgeries were done open, which is a much more challenging procedure for the patient,” Patel said. “Today, if a tumor is the appropriate size and location, open surgery just isn’t necessary. Through the nose, we get the best access and the best chance of complete removal.”

The procedure required a highly synchronized collaboration between two experts. Patel came up with the plan to navigate the complex nasal anatomy to create a clear surgical pathway. Archer had a severely deviated septum, and Patel likened the fix to "removing the sheetrock but leaving the studs" so that the nose wouldn't collapse.

Once the pathway was clear, Patel drove the endoscopic camera, providing high-definition, close-up visualization on a surgical monitor. This allowed Miller the crucial two-handed freedom required to safely dissect and extract the tumor.

“If he needs to get to critical structures, I can drive the camera closer, so he has perfect visualization,” Patel noted. “Dr. Miller takes on these complex cases when many surgeons wouldn't want to risk the complications or step out of their comfort zone. My skills in navigating the nasal approach are only useful because he is skilled enough to completely remove the tumor once we get there. Dr. Miller is very well equipped to do these surgeries. It is a true team effort.”

In July, the team successfully removed more than 99% of the benign mass, but a microscopic fraction of the tumor remained wrapped tightly behind Archer's optic nerve that if removed, carried major risks.

“You must ask, ‘Is it worth giving the patient a stroke or permanently changing their perfect vision just to get that last millimeter?’” Patel said. Prioritizing the patient's health, the team decided to leave that final fraction, confident that the tumor is highly unlikely to return.

“The biggest thing was to get the tumor out safely,” Patel added. “A minimally invasive approach through the nasal passages is more challenging and we are mindful of that [the tumor] has to be in a certain spot to go through the nose.”

To complete the surgery, the team performed a reconstruction of the skull base, using a small graft taken from Archer’s leg to seal the area and prevent spinal fluid leaks.

Just two days post-surgery, sitting in the Surgical Intensive Care Unit (SICU) at Walter Reed, Archer looked incredible, and there were no visible signs that had just undergone major brain surgery.

Archer’s vision had already started to clear, and while he was dealing with expected post-operative headaches and leg soreness from the graft, his spirits were high. He and his wife, Rebecca, have been blown away by the hospitality and professionalism of the Walter Reed staff.

“The care has been awesome. Amazing,” Archer said, giving special praise to SICU nurses, as well as the Physical and Occupational Therapy teams, especially Occupational Therapist Colleen Reilly.

Rebecca echoed his sentiments, noting that the on-campus Navy Lodge has provided a comfortable, supportive environment for their recovery process.

For surgeons Miller and Patel, and the Walter Reed Skull Base Team, Archer’s remarkable outcome highlights a broader mission: ensuring military beneficiaries know that they do not need to look to the civilian sector for cutting-edge medical care.

“I don’t think anyone else in the Defense Health Agency has this kind of team performing these complex skull base surgeries," Patel said. "Our goal is to make sure providers know this capability exists, so patients have the best options. Most patients are happy to stay in military healthcare.”

Thanks to an observant Navy doctor, a collaborative surgical dream team, and the innovative capabilities of Walter Reed, Archer’s toughest battle appears now behind him.
