RESUMEN
Objective: To analyse the clinical effect of endoscopy-assisted functional rhinoplasty. Methods: Twenty-one patients with congenital or traumatic deviated nose with nasal obstruction admitted to Qilu Hospital (Qingdao) from January 2018 to December 2021, including 8 males and 13 females, aged 22 to 46 years, were retrospectively analysed. Endoscopy-assisted functional rhinoplasty was performed in all patients. Deviated nasal septum was corrected, nasal septum cartilage graft was prepared through open approach assisted by endoscopy, the nasal frame structure was adjusted with the endoscopy-assisted rhinoplasty combined with middle and inferior turbinoplasty, and the patient's nasal ventilation function and external nose cosmetology were restored. Visual Analogue Scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE), nasal acoustic reflex and nasal resistance were examined preoperatively and 6 months postoperatively. The minimum cross-sectional area of the first two nasal cavities (MCA) MCA1 and MCA2 and their distance between nostrils to the minimum cross-sectional area (MD) MD1 and MD2 were recorded, and the ratio of both sides (expressed in a/b) was calculated. The nasal volume of 5 cm depth from nostril (NV5) and nasal resistance total (RT) were recorded to evaluate the nasal ventilation function to analyse the clinical effect of functional rhinoplasty assisted by nasal endoscope. SPSS 25.0 software was used for statistical analysis. Results: At 6 months after the operation, for nasal ventilation evaluation, the VAS and NOSE scores of nasal obstruction decreased significantly than those before the operation ((1.81±0.81) points vs (6.71±1.38) points, (4.19±2.06) points vs (12.05±2.67) points, all P<0.05). In the objective indexes, MCA1, MCA2 and NV5 were significantly increased whereas RT, MCA1a/MCA1b, MCA2a/MCA2b, MD1a/MD1b and MD2a/MD2b were significantly decreased compared with those before the operation (all P<0.05). The MD1 and MD2 levels before and after operation had no significant differences (all P>0.05). In the evaluation of external nose morphology, postoperative ROE was significantly increased, and the deviation value of nasal appearance was significantly decreased ((16.19±2.56) points vs (10.24±3.24) points, (1.55±1.16) mm vs (5.63±2.41) mm, all P<0.05). In terms of postoperative patient satisfaction, 19 cases (90.5%) were very satisfied with nasal ventilation function, 2 cases (9.5%) were satisfied with nasal ventilation function; 15 cases (71.4%) were very satisfied with nasal appearance, and 6 cases (28.6%) were satisfied with nasal appearance. Conclusions: Nasal endoscopy-assisted functional rhinoplasty can improve the nasal ventilation function and external nasal morphology at the same time, with good clinical effect and high patient satisfaction.
