Abstract:Objective To explore the anatomic characteristics of nasal septum deviation with external nasal deformity, and to summarize and analyze the surgical methods of nasal septum deviation correction and external nasal deformity restoration at the same time.Methods Clinical data of 18 patients undergoing nasal septum deviation correction and external nasal deformity reduction simultaneously from March 2016 to March 2019 were retrospectively analyzed. The deformity included pterygoid cartilage dysplasia (n=11), nasal septum cartilage caudal deformity(n=5), maxillary nasal spine deformity(n=2). All patients were treated with nasal septum deviation correction first, and suture, resection and support orthopedics were then performed alone or simultaneously according to the structural characteristics of different types of deformities. All patients were followed up for more than one year after operation, and visual analogue scale (VAS) scores of the nasal ventilation function and external nasal morphology before and after operation were compared.Results The VAS scores of nasal ventilation function and external nasal morphology one year after operation were significantly lower than those before operation, and the total resistance of bilateral nasal cavity after operation was also significantly lower than that before operation (P<0.05). Nasal endoscopy and computerized tomography of nasal cavity and paranasal sinuses revealed significant improvement of the deviation of nasal septum and the morphology of external nasal deformity in all 18 patients.Conclusion By summarizing the anatomical classification of nasal septum deviation and external nasal deformity and the experience of common surgical methods, a reference is provided for the treatment strategy of giving consideration to nasal function and aesthetics in clinical practice.
