Matsumoto Otolaryngology Clinic, located at 1-chome Kuwabara, Matsuyama City, Ehime Prefecture, is a clinic specializing in ear, nose, and throat care. Medical consultations are held from 9:00 AM to 12:00 PM and 2:00 PM to 6:00 PM. The clinic is closed on Sundays and holidays. The clinic provides English services and offers parking and barrier-free access. As Matsumoto Otolaryngology Clinic (a medical corporation), Dr. Yasushi Matsumoto, the director, provides medical care. The clinic has been performing laser treatments since 1994, conducting nasal surgeries using carbon dioxide lasers and myringotomies. Laser treatments are performed for nasal allergies and chronic rhinitis, and can be done as an outpatient procedure. Treatment is performed after outpatient examination when deemed necessary, using laser light from a handheld nasal device on the nasal mucosa after anesthesia with gauze soaked in medication. The procedure itself takes less than 5 to 10 minutes for both sides. On the day of treatment, driving, bathing, and light alcohol consumption are not problematic. It is said to be effective for approximately 75% of patients, particularly for nasal congestion. It does not cure the allergic constitution itself, and symptoms may appear when the amount of pollen dispersal is extremely high.
