Sierra Corbin, an ENT Specialist at Gulf Coast Breathe Free, said on Instagram that recurring sinus infections may be caused by structural abnormalities that medications alone cannot resolve.
“Sinus infections could keep returning despite prior treatment if there are some structural abnormalities,” said Corbin, according to Instagram. “If a sinus opening is narrowed, obviously antibiotics, nasal sprays, steroids are not going to treat that. We have procedural intervention that could assess that. Structural abnormalities may be contributing to your symptoms.”
According to the National Library of Medicine, structural abnormalities such as a deviated nasal septum or nasal polyps can impede sinus drainage. This obstruction can lead to recurrent sinus infections despite prior treatments. These anatomical issues hinder the normal flow of mucus, creating an environment conducive to chronic inflammation and infection. Addressing these structural problems is crucial for effective management of chronic sinusitis.
As reported by the National Center for Biotechnology Information (NCBI), when the sinus openings, or ostia, are narrowed due to structural abnormalities, medical treatments like antibiotics, nasal sprays, and steroids may not be effective. These medications cannot adequately reach the affected areas or restore proper drainage, leading to persistent symptoms. In such cases, surgical intervention may be necessary to correct the underlying anatomical issues.
Johns Hopkins notes that procedural interventions such as functional endoscopic sinus surgery (FESS) can assess and correct structural abnormalities contributing to chronic sinusitis. FESS involves using an endoscope to visualize and surgically address obstructions within the sinus passages, improving drainage and reducing inflammation. This minimally invasive approach has been shown to alleviate symptoms in patients unresponsive to medical therapy.
