Clinical efficacy of strengthening alar groove plasty in nasal tip reduction through internal incision / 中华医学美学美容杂志

ABSTRACT

Objective To investigate the effects of nasal tip reduction with inner incision combined with external fixation,namely,to evaluate the formation of bilateral alar groove which is en hanced by external fixation with small splints,after removing interdomal fat pad as well as adjusting alar cartilage to reduce nasal tip.Methods Alar cartilage and interdomal fat pad were exposed via the bilateral nasal vestibular incision to remove fat pad and part of enlarged lateral foot of alar cartilage.After suture of incision,based on the tissue removal,plastic splint was used for external fixation of bilateral nasal tip and alar groove for one week,to enhance the formation of alar groove.Results A total of 143 patients were followed up for more than 6 months after operation.Photographs taken before and after operation were compared,suggesting obviously smaller nasal tip and significant alar groove.Left and right alar groove space was decreased from preoperative (28.23±3.31) mm to post operative (23.72±2.65) mm,and nasal tip alar angle was decreased from (104.02±9.57)°to (87.78± 6.98)°,with statistical significance (P＜0.05).Slightly asymmetric nasal alars were found in 6 patients during follow-up examination,while tiny scars caused by splints (at 0.6 cm from the edge of splints) were found in 1 patient.Conclusions On the basis of nasal tip reduction with inner incision,the method of suture with small splints combined with external fixation is simple,effective and available.
