Huge Concha Bullosa and Septal Perforation: A Case Study.

INTRODUCTION: Concha bullosa is a usual anatomical variation of the nose and paranasal sinuses that can compromise their anatomy and function and cause such symptoms as headache, rhinosinusitis, and nasal congestion. Septal perforation is the defect of the septum that brings nasal cavities in communication and is usually caused by trauma. No septal perforation has been reported due to concha bullosa. CASE REPORT: The case of this report was a 15-year-old female who presented with long-term nasal obstruction due to a huge concha bullosa in her right nasal cavity which perforated nasal septum. She lacked a history of any nasal septum surgery, drug abuse, cocaine, or long-term nasal spray. Endoscopic surgery was performed and our patient's symptoms rapidly diminished after the surgery. Negative results were obtained for tuberculosis, Wegener's granulomatosis disease, and malignancy. CONCLUSION: We believe that the concha bullosa presented in this case might have caused chondrocyte apoptosis due to mechanical pressure and led to septal perforation. Although uncommon, providers should be aware of the possibility of septal perforation in cases with concha bullosa when planning to perform surgery on patients with similar pathology.
