"From childhood, Dr. Shinji Sakaguchi grew up observing his grandfather, an otolaryngologist, in clinical practice—making the field feel like home to him. Moreover, his childhood passion for delicate handicrafts resonated with the precision required in otolaryngological surgeries, which became one defining reason for his career choice."

"I consistently listen to every postoperative patient's feedback and suggestions. Even with the same condition, treatment must vary based on each patient's physical constitution and nasal anatomy - everyone deserves a truly personalized approach."

"Treating the very ailments that bring patients to seek medical care has always been my guiding principle as a physician. My ultimate goal is for every patient under my care to no longer need to visit the otolaryngology department again.
I meticulously explain customized treatment plans to each patient while fully respecting their choices."
— Dr. Shinji Sakaguchi
『患者様の病気を治す』というのが私の医療の目的でした。私の治療によって、すべての患者さんが耳鼻咽喉科に治療に行かなくて済むようになることを願っています。患者様お一人おひとりに合わせてご提案するオーダーメイドプランをご説明し、患者様の選択を尊重いたします。
In 1996, Dr. Shoji Sakaguchi founded the Sakaguchi Otorhinolaryngology Medical Group. Currently, he oversees the operations of six otorhinolaryngology hospitals and performs over a thousand surgeries annually.
In the field of nasal disease treatment, Dr. Sakaguchi is particularly proficient in a variety of highly difficult surgeries, including nerve block procedures, endoscopic turbinectomy, and radical sinusitis surgery. He has achieved remarkable results in treating refractory cases such as allergic rhinitis and chronic sinusitis.
In 1998, Dr. Sakaguchi was the first in Japan to perform endoscopic posterior nasal neurectomy, pioneering endoscopic nasal surgery in Japan. After years of refinement, the unique treatment methods of the "Sakaguchi School" have gradually taken shape, leading the industry. These methods have earned the trust and high praise of patients.
1996年、坂口伸治医師は坂口耳鼻咽喉科医療グループを設立し、現在6つの耳鼻咽喉科病院を統括し、年間1,000件以上の手術を行っている。鼻疾患治療の分野では、特に神経切断術（経鼻腔翼突管神経切除術）、根治的副鼻腔炎手術などの難手術を得意とし、アレルギー性鼻炎や慢性副鼻腔炎などの難治症例において顕著な実績を残している。1998年、坂口伸司医師は日本における内視鏡的後鼻神経切断術の先駆者となり、日本における内視鏡的鼻手術の先駆者となった。長年の改良を経て、業界をリードする「坂口流」とも呼ばれる独自の治療法が徐々に形成され、患者様からの信頼と賞賛をいただいている。
"Previously, when examined by another ENT doctor, I was consistently advised to pursue conservative treatment (such as oral medication) rather than surgery. The doctor cited my history of cleft lip and palate (having undergone surgery as a child) as the reason for not recommending an operation.
Consequently, before meeting Dr. Sakaguchi, I was somewhat apprehensive that he might decline the surgery for the same reasons. However, I vividly recall how Dr. Sakaguchi reassured me during our first consultation, stating, 'When we operate on your nasal septum, it won't affect your palate at all.' This statement immediately put my mind at ease.
For patients and their families, it is profoundly reassuring to witness how Dr. Sakaguchi explains procedures in an easily understandable manner—displaying real-time images of the nasal interior projected through an endoscope, conducting swift yet thorough examinations, and providing comprehensive explanations.
I entrusted my surgery to the highly experienced Dr. Sakaguchi with complete peace of mind."
