Treatment of Nasal Deviation With Underlying Bony Asymmetry Secondary to Augmentation Rhinoplasty in Asian Patients

In Asian patients, nasal deviation secondary to augmentation rhinoplasty may result from underlying bony asymmetry that was not corrected intraoperatively. Diagnosis and treatment of this condition are complicated by the masking effect of dorsal implants.

The authors applied computed tomography (CT) to examine the causes of nasal deviation after augmentation rhinoplasty. CT results were utilized in preoperative planning for revisional surgery.

Fifteen women with nasal deviation after augmentation rhinoplasty and CT-confirmed bony asymmetry were included in a retrospective study. To correct nasal deviation, the authors performed revisional rhinoplasty with paramedian osteotomy and unilateral placement of extended spreader grafts at the concave side of the keystone region. For patients with concomitant glabella-radix deviation, implants comprising expanded polytetrafluoroethylene or autologous fascia were placed.

Of the 15 patients with nasal bony asymmetry, 14 had developmental keystone asymmetry, and 1 had osteotomy-induced keystone deviation. Six patients had developmental glabella asymmetry. Patients received follow-up for an average of 11.2 months (range, 6-24 months). Revisional procedures were considered successful in 13 patients; 2 patients required additional surgery to address residual nasal deviation.

CT is valuable for the diagnosis of postaugmentation nasal deviation owing to underlying bony asymmetry. Paramedian osteotomy with extended spreader grafting at the concave side of the keystone area and correction of the glabella-radix deviation are effective procedures to reposition the nasal axis along the midline of the face.
