Clinician-Graded Electronic Facial Paralysis Assessment: The eFACE.

Background: The subjective nature of facial aesthetics and the difficulties associated with quantifying facial function have made outcomes analysis in facial paralysis challenging. Clinicians rely on photographs, subjective descriptions, and scales, limiting assessment, communication among providers, and communication between providers and patients. The authors describe the development and validation of a comprehensive, electronic, clinician-graded facial function scale (eFACE), which generates an overall disfigurement score and offers simple graphic output for clinician communication, assessment of various interventions, and patient understanding. The eFACE application may be used in a variety of electronic devices, including smartphones, tablets, and computers. Methods: An instrument consisting of 16 items in a visual analogue scale format was developed to assess facial function and symmetry (the eFACE). Video recordings of subjects performing facial expressions were viewed, and the eFACE instrument was applied, along with an overall facial disfigurement score. A multiple regression analysis was performed to determine the best linear relationship between overall expert-determined disfigurement and the eFACE items. The resulting equation was tested by three independent facial nerve clinicians, using an additional series of patients, to determine both interrater and intrarater reliability of the instrument. Results: Multiple regression analysis produced good fit of eFACE parameters to overall expert-rated global facial disfigurement when dynamic parameters were weighted twice as heavily as static and synkinesis parameters. eFACE scores demonstrated very high interrater and intrarater reliability. Conclusion: The eFACE is a reliable, reproducible, and straightforward digital clinical measure with which to assess facial function and disfigurement in patients with facial paralysis.

Objective Outcomes Analysis Following Microvascular Gracilis Transfer for Facial Reanimation: A Review of 10 Years’ Experience

IMPORTANCE Objective assessment of smile outcome after microvascular free gracilis transfer is challenging, and quantification of smile outcomes in the literature is inconsistent. OBJECTIVE To report objective excursion and symmetry outcomes from a series of free gracilis cases and investigate the predictive value of intraoperative measurements on final outcomes. DESIGN, SETTING, AND PARTICIPANTS A retrospective medical chart review was undertaken of all patients who underwent microvascular free gracilis transfer for smile at our institution over the past 10 years. MAIN OUTCOMES AND MEASURES Outcome measures included the following: smile excursion, angle of smile with respect to the vertical midline, and facial symmetry during repose and with smile. Measurements were obtained using an automated tool for assessment of facial landmarks (FACE-Gram). An exhaustive set of intraoperative parameters including degree of recoil of the gracilis muscle following harvest, the degree to which the muscle foreshortened during stimulation of the obturator nerve, final stretched length of the inset muscle, surgeon assessment of neurorrhaphy and pulse pressure, ischemia time, number of sutures used during neurorrhaphy, nerve used to innervate the flap, and surgeon assessment of oral commissure overcorrection were recorded and placed into a linear regression model to investigate correlations with smile. RESULTS From March 2003 to March 2013, 154 microvascular free gracilis transfers were performed for facial reanimation at our institution, 14 (9%) of which were deemed failures. Of the remaining 140 flaps, 127 fulfilled inclusion criteria and constituted the study cohort. Smile excursion, angle excursion, and symmetry of the oral commissure at repose and with smile all improved following gracilis free flap (P < .05). Associations between selected outcomes measures and intraoperative gracilis measurements were identified. CONCLUSIONS AND RELEVANCE Facial reanimation using free gracilis transfer results in quantifiable improvements in oral commissure excursion and facial symmetry both at rest and with smiling. Associations between contractility and internal recoil of the flap and final outcome were identified. LEVEL OF EVIDENCE 4

The success of free gracilis muscle transfer to restore smile in patients with nonflaccid facial paralysis.

BackgroundDevelopment of synkinesis, hypertonicity, and poor smile excursion after facial nerve insult and recovery contribute to disfigurement, psychological difficulties, and an inability to convey emotion via facial expression. Despite treatment with physical therapy and chemodenervation, some patients who recover from transient flaccid facial paralysis never spontaneously regain the ability to perform a meaningful smile. MethodsProspective evaluation was performed on 20 patients with nonflaccid facial paralysis who underwent free gracilis muscle transfer. Patients were evaluated using the quality-of-life (QOL) FaCE survey, Facial Nerve Grading Scale, and Facegram to quantify QOL improvement, smile excursion, and symmetry after muscle transfer. ResultsA statistically significant increase in the FaCE score was seen after muscle transfer (paired 2-tailed t test, P < 0.039). In addition, there was a statistically significant improvement in the smile score on the Facial Nerve Grading Scale (P < 0.002), in the lower lip length at rest (P = 0.01) and with smile (P = 0.0001), and with smile symmetry (P = 0.0077) after surgery. ConclusionsFree gracilis muscle transfer has become a mainstay in the management armamentarium for patients who develop severe reduction in oral commissure movement after facial nerve insult and recovery. The operation achieves a high overall success rate, and innovations involving transplanting thinner segments of muscle avoid a cosmetic deformity secondary to excess bulk. This study demonstrates a quantitative improvement in QOL and facial function after free gracilis muscle transfer in patients who failed to achieve a meaningful smile after physical therapy.

Optimizing Total Facial Nerve Patient Management for Effective Clinical Outcomes Research

IMPORTANCE Assessment of outcomes in patients with facial paralysis is challenging owing to the lack of objective tools to evaluate facial function and suboptimal data collection. OBJECTIVE To describe a methodology for prospective evaluation of patients with facial paralysis that permits optimal assessment of clinical outcomes. DESIGN, SETTING, AND PARTICIPANTS At the Massachusetts Eye and Ear Infirmary, we have treated over 2000 patients with facial nerve injury since 2002. To better quantify and improve our outcomes, we have developed what we now believe represents a systematic method for the previsit evaluation, intake, management, and follow-up of our facial nerve patients to optimize data collection for the purposes of clinical outcome studies, as detailed in this retrospective descriptive study. RESULTS Data collection is often poor if there is not a specific individual delegated to the task and is particularly challenging in the intraoperative setting. Retrospective acquisition of data are inherently less accurate and time consuming. A user-friendly searchable database is required to use the collected data. CONCLUSIONS AND RELEVANCE Clinical outcomes research in the field of facial paralysis requires meticulous attention to comprehensive data collection at appropriate time points, precision photography, and the use of available quality of life and objective measurement tools. Ideally, a standardized approach for data collection would be adopted that would permit multi-institutional data analysis to improve the quality of outcomes research currently available.

Head and neck free flap reconstruction in patients older than 80 years.

BACKGROUND Free tissue transfer is a reliable method for reconstruction of head and neck defects. With the growing number of octogenarians in the population, it is important to understand how these patients respond to these procedures. METHODS Through a retrospective chart review of patients who underwent a free-flap reconstruction from 2000 to 2010 at an academic medical center, 48 patients, aged 80 years and older, were compared with a control group consisting of 97 similar patients, aged younger than 80 years. We compared the intensive care unit (ICU) length of stay, overall hospital stay, and the incidence of perioperative complications between the cohorts. RESULTS The average length of stay in the ICU was significantly longer for the octogenarian group as compared with the younger group (101 vs. 41 hours, p-value = 0.007). The average length of hospital stay was not significantly different between the two groups (difference = 40 hours, p-value = 0.102). The incidence of perioperative complication was 75% in the octogenarian group and 60% in the younger group (p-value = 0.095). There were two flap failures in the younger group, and none in the octogenarian group. There was a significantly higher rate of death within 30 days in the octogenarian group. CONCLUSIONS Microvascular free tissue transfer is a reliable and safe method of reconstruction of head and neck defects in patients over 80 years of age. Patients should be counseled about the potential risks of increased incidence of medical complications, ICU length of stay, and rate of perioperative death when recommended to undergo free tissue transfer reconstruction.

Prospective Evaluation of Quality-of-Life Improvement After Correction of the Alar Base in the Flaccidly Paralyzed Face

IMPORTANCE Nasal valve collapse caused by facial palsy is an often overlooked but disturbing sequela of flaccid facial paralysis. OBJECTIVE To prospectively study the effect of fascia lata sling placement for correction of external nasal valve compromise in patients with flaccid facial paralysis, using a validated disease-specific quality-of-life outcome survey. DESIGN, SETTING, AND PARTICIPANTS This was a prospective study of 68 patients from March 2009 to December 2013 who underwent fascia lata sling placement for correction of external nasal valve compromise. INTERVENTION Fascia lata sling placement for the correction of external nasal valve compromise . MAIN OUTCOME AND MEASURE Nasal Obstruction Symptom Evaluation (NOSE) scale. RESULTS Sixty-eight disease-specific quality-of-life determinations were performed using the NOSE scale. Ratings were ascertained preoperatively and postoperatively. Sixty patients completed a NOSE scale prior to surgical intervention, and 40 completed the survey after intervention. There was a statistically significant difference in NOSE scores after fascia lata sling placement The mean preoperative NOSE score was 37.6 (27.1), and the mean postoperative score was 16.6 (17.37) (Wilcoxon signed-rank test; P < .001). All patients had improvement in their nasal obstruction, which persisted uniformly in follow-up. CONCLUSIONS AND RELEVANCE The nasal valve is a zone that has historically been neglected, despite the fact that a highly effective surgical solution has existed for decades. We highlight the significance of nasal valve dysfunction in patients with flaccid facial paralysis, demonstrate a quantitative benefit in disease-specific quality of life after fascia late sling placement for external nasal valve compromise, and suggest an updated treatment algorithm. This method offers a predictably successful, straightforward surgical solution to an overlooked functional problem in the patient with flaccid facial paralysis. LEVEL OF EVIDENCE 4.

Development and Validation of a Spontaneous Smile Assay

IMPORTANCE Smiling can be a voluntary or involuntary movement. Facial reanimation procedures differ in their ability to restore a spontaneous smile, and an assay designed to evoke and evaluate a spontaneous smile is not available. OBJECTIVE To develop and validate an assay to assess the spontaneous smile of patients with facial paralysis. DESIGN, SETTING, AND PARTICIPANTS This was an exploratory cohort study. A series of short video clips were administered to laypersons via an online survey service from January 1, 2014, to March 31, 2014. Respondents rated how funny each video was on a visual analog scale from 0 to 100. The 4 funniest videos were selected to generate a 1½-minute spontaneous smile assay. The assay was then administered from July 1, 2014, to December 31, 2014, to 2 different study groups: the first was composed of 100 healthy individuals (control group) and the second was composed of 30 patients with facial paralysis. We analyzed the capability of this assay to provoke at least 1 spontaneous smile and calculated smile excursion in both groups. Statistical analysis was performed using analysis of variance. INTERVENTION Spontaneous smile assay administered to both healthy and diseased groups. MAIN OUTCOMES AND MEASURES Ability of the assay to elicit smiles, as defined by an oral commissure excursion greater than 3 mm, as well as difference in commissure excursion. RESULTS Ninety-five (95.0%) participants in the control group and 29 (96.7%) patients with facial paralysis experienced at least 1 oral commissure excursion that appeared to be a spontaneous smile while viewing the assay. Mean oral commissure excursion with spontaneous smile was 9.08 mm (95% CI, 2.77-15.39) in controls, 6.72 mm (95% CI, 3.13-10.31) on the healthy side in patients with flaccid facial paralysis (P=.004 vs controls), and 9.64 mm (95% CI, 3.52-15.76) on the healthy side in patients with nonflaccid facial paralysis (P=.74). Among patients with flaccid facial paralysis, a statistically significant difference was found between smile excursion of the affected and the unaffected sides (P = .03). There was no statistically significant difference in the measurement between sides for the control group (P = .67). CONCLUSIONS AND RELEVANCE Although humor is a challenging construct to universalize, our assay was able to elicit a smile in almost all individuals in the group with facial paralysis and the control group. The spontaneous smile assay will facilitate future research on the ability of facial reanimation procedures and other interventions to restore a spontaneous smile. LEVEL OF EVIDENCE NA.

The Effects of Intensive Care Unit Staffing on Patient Outcomes Following Microvascular Free Flap Reconstruction of the Head and Neck: A Pilot Study

OBJECTIVE To determine if the implementation of the closed intensive care unit (ICU) at our institution altered clinical outcomes in patients who had undergone microvascular free flap reconstruction of the head and neck by the Otolaryngology-Head and Neck Surgery Service. DESIGN Retrospective medical chart review. SETTING A single tertiary medical center. PATIENTS The open ICU cohort had 52 flaps performed on 50 patients, and the closed ICU cohort had 52 flaps performed on 52 patients. MAIN OUTCOME MEASURES Fifty-two free flap reconstructions of head and neck defects were performed on 50 patients who were admitted to an open ICU. The length of stay (LOS) in the ICU and hospital and incidence of complications were compared with those of 52 patients who underwent 52 free flap reconstructions and were admitted to a closed ICU over a separate period. RESULTS The mean length of stay in the ICU was 44 and 45 hours in the open and closed ICU cohorts, respectively (P = .90). The incidence of surgical and medical complications was similar in the open and closed ICU cohorts (P > .05). CONCLUSIONS There does not appear to be a significant difference in patient outcome between open and closed ICU care in our study.
