Maxillary sinus pathology includes a range of conditions affecting the maxillary sinuses, such as sinusitis, cysts, polyps, fungal infections, and tumors. These conditions may arise from infections, allergies, or dental issues. Common symptoms include facial pain or pressure, nasal congestion, postnasal drip, and sometimes toothache. Diagnosis often involves clinical evaluation and imaging studies like X-rays or CT scans. Treatment varies depending on the cause and may include medications such as antibiotics or antihistamines, and in some cases, surgical intervention to restore normal sinus function.
