ENT & Sinus Services Available At Our Powdersville Office
At Atreus Medical & Surgical Associates, we offer advanced diagnostic evaluation using our in-office sinus CT scanner to identify the source of your symptoms without having to go to visit an imaging center or other office. This advanced imaging allows Dr. Boxwell and our team to visualize your sinuses and nasal packages right here at our Powdersville office and without requiring a trip to a hospital or imaging center. From there, we’ll develop a personalized treatment plan to help you breathe better. If necessary, that may involve minimally invasive sinus procedures, including:

Obstructive Sleep Apnea Identification & Management
Sleep apnea is a common but often underdiagnosed condition that can significantly affect your health and quality of life. Many people assume snoring is simply an annoyance, but it can be a sign of obstructive sleep apnea (OSA), a condition that causes repeated interruptions in breathing during sleep. At Atreus Medical & Surgical Associates, we focus on identifying upper airway issues and any other contributing conditions. Airway issues can make CPAP therapy more difficult and improving nasal airflow can play a significant role in better sleep.
Migraine Management
Migraines are more than bad headaches, and involve much more than painful headaches. In addition to pain, people with migraines often experience nausea, dizziness, sensitivity to light and sound and more that can make everyday life extremely difficult. Our approach to understanding and controlling your migraines starts by completing an consultation to identify factors that may contribute to your migraine symptoms while mapping out patterns and identifying your triggers. We want to help find successful management so you can spend less time managing your migraines and more time enjoying and living your life.
