  1. JAMA Facial Plastic SurgeryJournal Club Slides:Objective Assessment of Smile Outcomes Bhama PK, Weinberg JS, Lindsay RW, Hohman MH, Cheney ML, Hadlock TA. Objective outcomes analysis following microvascular gracilis transfer for facial reanimation: a review of 10 years’ experience. JAMA Facial Plast Surg. Published online January 30, 2014. doi:10.1001/jamafacial.2013.2463.

  2. Introduction • Gracilis free tissue transfer (GFTT) is the gold standard for dynamic reanimation of the oral commissure. • Objective assessment of smile outcome after microvascular free gracilis transfer is challenging, and quantification of smile outcomes in the literature is inconsistent. • Lack of objective outcomes measurements makes it challenging to predict outcomes based on patient characteristics and intraoperative events.

  3. Purpose • The purpose of this study was to quantify smile outcomes in patients following GFTT and find relationships between intraoperative parameters and outcomes.

  4. Relevance to Clinical Practice • The advancement of facial reanimation treatment is dependent on the ability of facial plastic surgeons to reliably quantify results so that comparisons between current treatments and novel procedures can be made. • If associations between perioperative parameters and ultimate outcomes can be determined, clinicians can more accurately educate and prepare patients for the results of their interventions.

  5. Description of Evidence • All patients who underwent GFTT at the Massachusetts Eye and Ear Infirmary from March 2003 to March 2013 were included in the study. Patients with flap failure and patients who were still in the process of recovery were excluded.

  6. Description of Evidence Face-GRAM software used to make facial measurements. 1, Horizontal interpupillary line; 2, vertical line bisecting and perpendicular to horizontal interpupillary line; A, intersection of line 2 and vermilliocutaneous border of lower lip; B, oral commisure; 3, line with distance spanning points A and B; and a, angle between line 2 and line 3.

  7. Description of Evidence Gracilis muscle following inset.

  8. Description of Evidence Preoperative and postoperative gracilis recipients. Left column represents trigeminally innervated flaps; right column represents flaps innervated by contralateral facial nerve.

  12. Controversies and Consensus • Our data only reflect 2-dimensional measurements of facial movement and do not account for the Z plane, which is an important metric. • The average postoperative excursion in our study was 8 mm, which is similar to smile excursion in the normal population. • Excursion in trigeminally innervated flaps is greater than in flaps innervated by the contralateral facial nerve.

  13. Comment • Larger, prospective studies are indicated to better define associations between intraoperative gracilis muscle parameters and outcomes. • It is important to investigate quality-of-life changes following GFTT to determine whether associations between quality of life and objective measurements exist.

  14. Conclusions • GFTT is a reliable procedure for dynamic reanimation of the paralyzed oral commissure and results in measureable improvements in smile excursion and oral commissure symmetry.
