Case Series of Minimal Invasive Tanongsak Technique for Reduction Malarplasty in 411 Patients

Background

Southeast Asian women prefer oval shape facial contour. To achieve this goal, there are a lot of procedures to reshape the facial skeleton. Reduction malarplasty is a common operation. Although multiple technique have been developed for reduction malarplasty. This study presents a new less invasive TANONGSAK technique for reduction malarplasty.

Methods

Between January 2015 and December 2017, we applied TANONGSAK technique for reduction malarplasty inconsecutive 411 patients. TANONGSAK technique was performed by only one surgeon and all 411 patients have same procedure. Technique was performed by osteotomy site at zygomatic arch with 12 mm in length preauricular incision and at zygomatic body with 25 mm in length intraoral incision by a reciprocating saw. Out site-in Closed reduction was performed to reposition of malar bone complex. Internal fixation was not required.

Results

The patients were followed up for 5 to 183 days postoperatively (mean 33 days). 97.8% of patients (402 patients) had satisfactory aesthetic results. The facial contour reduction was accomplished 0.1%-13.79% (mean 2.46%) in size reduction by photograph measured. The operative time in most case was less than 60 minutes (mean 41 minutes ,20-90minutes). The mean hospital stay was 1.06 day (1-2 day) and patients required recovery period 2-14 days (mean 8.7 days) .8 of patients developed temporary inferior orbital nerve injury.1 of patients developed delay union of zygomatic arch.  No facial nerve injury and no any other postoperative complications.

Conclusion

Minimal invasive TANONGSAK technique reduction malarplasty is a preferable technique. This technique provides multiple advantages, including simple manipulation, less invasive, short incision, no internal fixation, good stability, achieved aesthetic results, short operative and recovery time, and less complications.
