Microdebrider Surgery Removes Nasal Polyps so Patients Can Breathe Again

       Are you a long-time sufferer of nasal congestion? It may be caused by nasal polyps. Mr. Lin, 49 years old, has been suffering from left nasal congestion for 5 years. His symptoms included purulent nasal discharge and swelling of the left cheek, severely affecting his living and sleeping quality. Mr. Lin was admitted to the Division of Otolaryngology due to increasingly severe symptoms.

       Clinical diagnosis showed that Mr. Lin’s left nasal cavity has been completely filled by nasal polyp, with the polyp visibly extruded from the nostril. The left ala of the nose was stretched by the polyp, resulting in an unsymmetrical appearance of the left and right nose alae. CT scans have shown that the left nasal cavity, upper sinus and posterior nostril have been completely filled with polyp. Pathological biopsies have confirmed the presence of an antrochoanal polyp. After discussion with the physician, Mr. Lin decided to undergo endoscopic sinus surgery using a microdebrider. The post-surgical recovery for Mr. Lin was good, and he successfully regained the ability to breathe smoothly.

       According to Dr. Chu Chun-wei, Director of the Division of Otolaryngology at the Taipei City Hospital Zhongxiao Branch, the antrochoanal polyp is a type of nasal polyp that accounts for 4~6% of nasal polypi in adults, and about 33% of nasal polypi in children. Most are confined to one side of the nose.

       The mainstream treatment for antrochoanal polyps is endoscopic sinus surgery, says Dr. Chu. The treatment principles involve the clearing of polypi and the removal of mucosa near the stalk root of the polyp in the maxillary sinus to prevent future relapses. The use of a microdebrider can rapidly reduce the time needed for surgery, reduce bleeding and improve the surgical field of vision, ensuring that the nasal polypi can be cleared completely to prevent relapses, and at the same time preserve most of the normal nasal mucosa.
