ABSTRACT

This study evaluated the efficacy and safety of IncobotulinumtoxinA 20 U for treatment of glabellar frown lines in Chinese subjects. Methods: This was a prospective, randomized, double-blind, active-controlled, phase-3 study conducted in China. Subjects with moderate to severe glabellar frown lines at maximum frown were randomized to receive IncobotulinumtoxinA (N = 336) or OnabotulinumtoxinA (N = 167). Results: For the primary efficacy endpoint at day 30, response rates at maximum frown (score "none" or "mild") on the Merz Aesthetic Scales Glabella Lines - Dynamic were comparable between IncobotulinumtoxinA (92.5%) and OnabotulinumtoxinA (95.1%) per investigator's live rating. Noninferiority of IncobotulinumtoxinA versus OnabotulinumtoxinA was successfully demonstrated, as the two-sided 95% confidence interval of -0.97% to 0.43% for the difference in Merz Aesthetic Scales-based response rates (-0.27%) lay completely above the predefined noninferiority margin of -15%. For the secondary efficacy endpoints assessed at day 30, Merz Aesthetic Scales-based response rates (score "none" or "mild") at maximum frown were similarly comparable between both groups per subject (>85%) and independent review panel (>96%) rating. Per Global Impression of Change Scales, greater than 80% of subjects and greater than 90% of investigators in both groups rated treatment results as at least "much improved" at day 30 compared with baseline. Safety profiles were consistent between groups; IncobotulinumtoxinA was well tolerated, and no new safety concerns were identified in Chinese subjects. Conclusion: IncobotulinumtoxinA 20 U is safe and effective for treatment of moderate to severe glabellar frown lines at maximum frown in Chinese subjects and is noninferior to OnabotulinumtoxinA 20 U.

ABSTRACT

PURPOSE: This pooled analysis of data from three Phase 3 studies investigated the effects of incobotulinumtoxinA on spasticity-related pain (SRP) in children/adolescents with uni-/bilateral cerebral palsy (CP). METHODS: Children/adolescents (ambulant and non-ambulant) were evaluated for SRP on increasingly difficult activities/tasks 4 weeks after each of four incobotulinumtoxinA injection cycles (ICs) using the Questionnaire on Pain caused by Spasticity (QPS; six modules specific to lower limb [LL] or upper limb [UL] spasticity and respondent type [child/adolescent, interviewer, or parent/caregiver]). IncobotulinumtoxinA doses were personalized, with all doses pooled for analysis. RESULTS: QPS key item responses were available from 331 and 155 children/adolescents with LL- and UL-spasticity, respectively, and 841/444 (LL/UL) of their parents/caregivers. IncobotulinumtoxinA efficacy was evident with the first IC. Efficacy was sustained and became more robust with further subsequent ICs. By Week 4 of the last (i.e. fourth) IC, 33.8-53.3% of children/adolescents reported complete SRP relief from their baseline pain for respective QPS items. Children/adolescents reported reductions in mean LL SRP intensity at levels that surpassed clinically meaningful thresholds. Similarly, parents/caregivers observed complete SRP relief and less frequent SRP with incobotulinumtoxinA. Similar results were found for UL SRP. CONCLUSION: These findings indicate that incobotulinumtoxinA could bring considerable benefit to children/adolescents with spasticity by reducing SRP, even during strenuous activities.

ABSTRACT

IncobotulinumtoxinA, a pure botulinumtoxinA formulation, is free of accessory proteins. This analysis provides pooled safety data from phase 3 trials of children/adolescents (2-17 years), investigating incobotulinumtoxinA for the treatment of spasticity associated with cerebral palsy (at doses ≤20 U/kg (max. 500 U) per injection cycle (IC) for ≤6 ICs; three trials) or sialorrhea associated with neurologic disorders (at total doses of 20-75 U per IC for ≤4 ICs; one trial) for ≤96 weeks. Safety endpoints included the incidences of different types of treatment-emergent adverse events (TEAEs) and immunogenicity. IncobotulinumtoxinA dose groups were combined. Of 1159 patients (mean age 7.3 years, 60.4% males) treated with incobotulinumtoxinA, 3.9% experienced treatment-related TEAEs, with the most common being injection site reactions (1.3%) (both indications), muscular weakness (0.7%) (spasticity), and dysphagia (0.2%) (sialorrhea). Two patients (0.2%) experienced a treatment-related treatment-emergent serious adverse event, and 0.3% discontinued the study due to treatment-related TEAEs. No botulinumtoxinA-naïve patients developed neutralizing antibodies (NAbs) after incobotulinumtoxinA. All children/adolescents with known pre-treatment status and testing positive for Nabs at final visit (n = 7) were previously treated with a botulinumtoxinA other than incobotulinumtoxinA. IncobotulinumtoxinA was shown to be safe, with very few treatment-related TEAEs in a large, diverse cohort of children/adolescents with chronic conditions requiring long-term treatment and was without new NAb formation in treatment-naïve patients.

ABSTRACT

Objective: To confirm the efficacy and safety of incobotulinumtoxinA (Xeomin®, Merz Pharmaceuticals GmbH; total dose 400 U) in Japanese subjects with lower limb (LL) poststroke spasticity using the Modified Ashworth Scale spasticity score for the plantar flexors (MAS-PF). Methods: This phase III study (Japic clinical study database No. CTI-153030, 7 October 2015) included a double-blind, 12-week main period (MP) in which 208 subjects were randomized to receive one injection cycle of incobotulinumtoxinA 400 U (n = 104) or placebo (n = 104) in the pes equinus muscles, and an open-label extension (OLEX) that enrolled 202 subjects who received three injection cycles, 10-14 weeks in duration (the last cycle was fixed at 12 weeks). Changes in MAS-PF for incobotulinumtoxinA vs. placebo from baseline to Week 4 of the MP and to the end-of-cycle visits in the OLEX were evaluated. Results: The area under the curve for the change in MAS-PF was statistically significantly greater with incobotulinumtoxinA vs. placebo in the MP (mean: -7.74 vs. -4.76; least squares mean: -8.40 vs. -5.81 [p = 0.0041]). In the OLEX, mean changes in MAS-PF from baseline to end-of-study showed continued improvement with repeated injections. No new safety concerns were observed with the incobotulinumtoxinA treatment. Its efficacy and safety were consistent regardless of the length of the injection cycle interval in the OLEX. Conclusion: This study demonstrated that incobotulinumtoxinA (total dose 400 U) is an effective and a well-tolerated treatment for LL spasticity in Japanese subjects using flexible injection intervals of 10-14 weeks.

ABSTRACT

PURPOSE: A large prospective database from three Phase 3 studies allowed the study of spasticity-related pain (SRP) in pediatric cerebral palsy (CP). METHODS: Baseline (pretreatment) SRP data occurring during different activities in children/adolescents (aged 2-17 years, ambulant/nonambulant) with uni-/bilateral spastic CP was obtained using the Questionnaire on Pain caused by Spasticity (QPS; six modules specific to spasticity level [lower limb (LL) or upper limb (UL)] and type of respondent [child/adolescent, interviewer, or parent/caregiver]). RESULTS: At baseline, 331 children/adolescents with LL- and 155 with UL-spasticity completed at least one key item of their modules; LL/UL QPS modules of parent/caregivers were at least partially completed (key items) by 841/444 parents/caregivers. SRP with at least one activity at baseline was self-reported in 81.9% /69.7% (LLs/ULs) of children/adolescents with spasticity. Parents/caregivers observed LL/UL SRP behaviors in 85.9% /77.7% of their children, with multiple body regions affected. SRP negatively affected the great majority of the children in various ways. Child/adolescent-reported mean SRP intensity and parent/caregiver-observed mean SRP behavior frequencies were higher for LLs than ULs, and the level of SRP increased with more physically demanding activities. CONCLUSION: These data suggest SRP is more common and intense in pediatric CP than generally thought, emphasizing the need for effective, long-term pain management.

ABSTRACT

PURPOSE: The open-label phase 3 "Treatment with IncobotulinumtoxinA in Movement Open-Label" (TIMO) study investigated longer-term safety and efficacy of incobotulinumtoxin A in children/adolescents with cerebral palsy (CP). METHODS: Patients on standard treatment, with unilateral or bilateral lower limb (LL) or combined upper limb (UL)/LL spasticity received four incobotulinumtoxinA injection cycles (16 or 20 Units/kg bodyweight total [maximum 400 or 500 Units] per cycle depending on ambulatory status/clinical pattern treated), each followed by 12-16 weeks' observation. Treatment for pes equinus was mandatory; flexed knee or adducted thigh were options for unilateral treatment and/or ULs for unilateral/bilateral treatment. The primary endpoint was safety; changes in Ashworth Scale and Gross Motor Function Measure-66 scores, and Global Impression of Change Scale scores at week 4 of each injection cycle were also evaluated. RESULTS: IncobotulinumtoxinA (≤500 Units for ≤98 weeks) was safe, well-tolerated, and effective across all endpoints for multipattern treatment of LL and combined LL/UL spasticity in ambulant/nonambulant children/adolescents with CP. Treatment effects increased with each injection cycle. No new/unexpected safety concerns were identified. CONCLUSION: IncobotulinumtoxinA showed a good safety and tolerability profile, with efficacy over multiple clinical presentations. As an adjunct treatment, it offers an effective, individualized treatment option for pediatric CP-related spasticity.

ABSTRACT

BACKGROUND: This randomized phase 3 study with double-blind main period (MP) and open-label extension (OLEX; NCT02002884) assessed incobotulinumtoxinA safety and efficacy for pediatric upper-limb spasticity treatment in ambulant/nonambulant (Gross Motor Function Classification System [GMFCS] I-V) patients, with the option of combined upper- and lower-limb treatment. METHODS: Patients were aged two to 17 years with unilateral or bilateral spastic cerebral palsy (CP) and Ashworth Scale (AS) score ≥2 in treatment-selected clinical patterns. In the MP, patients were randomized (2:1:1) to incobotulinumtoxinA 8, 6, or 2 U/kg body weight (maximum 200, 150, 50 U/upper limb), with optional lower-limb injections in one of five topographical distributions (total body dose ≤16 to 20 U/kg, maximum 400 to 500 U, depending on body weight and GMFCS level). In the OLEX, patients received three further treatment cycles, at the highest MP doses (8 U/kg/upper limb group). Outcomes included AS, Global Impression of Change Scale (GICS), and adverse events (AEs). RESULTS: AS scores improved from baseline to week 4 in all MP dose groups (n = 350); patients in the incobotulinumtoxinA 8 U/kg group had significantly greater spasticity improvements versus the 2 U/kg group (least-squares mean [standard error] for upper-limb main clinical target pattern -1.15 [0.06] versus -0.93 [0.08]; P = 0.017). Investigator's, child/adolescent's, and parent/caregiver's GICS scores showed improvements in all groups. Treatment benefits were sustained over further treatment cycles. AE incidence did not increase with dose or repeated treatment across GMFCS levels. CONCLUSIONS: Data provide evidence for sustained efficacy and safety of multipattern incobotulinumtoxinA treatment in children and adolescents with upper-limb spasticity.

ABSTRACT

PURPOSE: Investigate the efficacy and safety of multipattern incobotulinumtoxinA injections in children/adolescents with lower-limb cerebral palsy (CP)-related spasticity. METHODS: Phase 3 double-blind study in children/adolescents (Gross Motor Function Classification System - Expanded and Revised I-V) with unilateral or bilateral spastic CP and Ashworth Scale (AS) plantar flexor (PF) scores ⩾ 2 randomized (1:1:2) to incobotulinumtoxinA (4, 12, 16 U/kg, maximum 100, 300, 400 U, respectively) for two 12- to 36-week injection cycles. Two clinical patterns were treated. Pes equinus (bilateral or unilateral) was mandatory; if unilateral, treatment included flexed knee or adducted thigh. ENDPOINTS: Primary: AS-PF change from baseline to 4 weeks; Coprimary: investigator-rated Global Impression of Change Scale (GICS)-PF at 4 weeks; Secondary: investigator's, patient's, and parent's/caregiver's GICS, Gross Motor Function Measure-66 (GMFM-66). RESULTS: Among 311 patients, AS-PF and AS scores in all treated clinical patterns improved from baseline to 4-weeks post-injection and cumulatively across injection cycles. GICS-PF and GICS scores confirmed global spasticity improvements. GMFM-66 scores indicated better motor function. No significant differences between doses were evident. Treatment was well-tolerated, with no unexpected treatment-related adverse events or neutralising antibody development. CONCLUSION: Children/adolescents with lower-limb spasticity experienced multipattern benefits from incobotulinumtoxinA, which was safe and well-tolerated in doses up to 16 U/kg, maximum 400 U.

ABSTRACT

BACKGROUND: Clinical photonumeric scales have been developed and validated to objectively measure the effectiveness of aesthetic treatments in specific anatomical areas; however, these are based on the typical features of Caucasian patients. No clinical scale for Asian calf appearance currently exists. OBJECTIVE: To develop and validate a calf assessment scale for use in the female Asian patient population. METHODS AND MATERIALS: During 2 validation sessions, 13 raters assessed calf images of female Asian subjects (N = 35) viewed from behind with feet flat on the floor (at rest) and on tiptoes (dynamic). Images were rated from 0 (very slim, linear profile) to 4 (very severe convex profile). RESULTS: Inter-rater and intra-rater reliability were "substantial" (≥0.6, intraclass correlation coefficient [ICC] and weighted kappa) for the calf-at rest, calf-dynamic, and calf summary score. Reliability was "substantial" for calf-at rest and calf-dynamic (≥0.6, ICC and weighted kappa) and "almost perfect" (0.85) for the calf summary score. BMI and calf circumference were highly correlated with scale ratings, and calf circumference was a significant predictor. CONCLUSION: This new photonumeric assessment scale has value for assessing the female Asian calf, providing a standardized measure of calf appearance in clinical practice and clinical research settings.

ABSTRACT

BACKGROUND: New treatment methods for cellulite require globally accepted scales for aesthetic research and patient evaluation. OBJECTIVE: To develop a set of grading scales for objective assessment of cellulite dimples on female buttocks and thighs and assess their reliability and validity. MATERIALS AND METHODS: Two photonumeric grading scales were created and validated for dimples in the buttocks in female patients: Cellulite Dimples-At Rest, and Cellulite Dimples-Dynamic. Sixteen aesthetic experts rated photographs of 50 women in 2 validation sessions. Responses were analyzed to assess inter-rater and intra-rater reliability. RESULTS: Overall inter-rater reliability and intra-rater reliability were both "almost perfect" (≥0.81, intraclass correlation efficient and weighted kappa) for the At Rest scale. For the Dynamic scale, inter-rater reliability and intra-rater reliability were "substantial" (0.61-0.80). There was a high correlation between the cellulite scales and body mass index, age, weight, and skin laxity assessments. CONCLUSION: Consistent outcomes between raters and by individual raters at 2 time points confirm the reliability of the cellulite dimple grading scales for buttocks and thighs in female patients and suggest they will be a valuable tool for use in research and clinical practice.

ABSTRACT

BACKGROUND: The demand for noninvasive skin-tightening body procedures is increasing. OBJECTIVE: To develop a set of grading scales for the objective assessment of skin laxity and assess their reliability and validity. MATERIALS AND METHODS: Two photonumeric grading scales were created and validated for skin laxity in female patients: Skin Laxity-Posterior Thighs/Buttocks, and Anterior Thighs/Knees. Fifteen aesthetic experts rated photographs of 50 women in 2 validation sessions. Responses were analyzed to assess inter-rater and intra-rater reliability. RESULTS: Overall inter-rater reliability according to intraclass correlation efficient (ICC) 2.1 and weighted kappa was at least "substantial" for both scales in both sessions, and "almost perfect" (≥0.81) for the Anterior Thighs and Knees scale in session 2. Intra-rater reliability was "almost perfect" for both scales (ICC 2.1) and "substantial" to "almost perfect" by weighted kappa. A correlation between the skin laxity scales and body mass index, age, weight, sun exposure, and cellulite severity was observed. CONCLUSION: The skin laxity photonumeric grading scales are valid and reliable instruments for assessing laxity on the posterior thighs and buttocks, and anterior thighs and knees. The scales will be of value for standardizing clinical evaluations and quantifying outcome measurements in research and clinical practice.

ABSTRACT

BACKGROUND: As the number of different aesthetic treatments increase, numerous photonumeric assessment scales have been developed and validated to measure the effectiveness of these new treatments and techniques. Photonumeric rating scales have been developed to objectively assess improvements in anatomical areas; however, these have been based on the features of Caucasian patients. OBJECTIVE: To develop and validate a Chin Projection Scale for use in the female Asian patient population. METHODS AND MATERIALS: During 2 validation sessions, 13 raters assessed full frontal and lateral facial views of 50 Asian subjects and also estimated their age and the aesthetic treatment effort required for each subject. Chin projection was rated on a scale from 0 (optimal) to 4 (very severely receding). RESULTS: Inter-rater reliability was 0.80 (substantial) for Validation Session 1 and 0.83 (almost perfect) for Validation Session 2. The results for Estimated Age and Estimated Treatment Effort were essentially the same. CONCLUSION: This study demonstrated the validity of the first photonumeric assessment scale for assessing the appearance of the female Asian chin. This new scale will provide a standardized measure of chin projection for Asian patients in clinical practice and clinical research settings.

ABSTRACT

BACKGROUND: As the number of aesthetic treatments has grown, so have the number of photonumeric assessment scales used to compare the effectiveness of these aesthetic treatments in specific anatomical areas; however, these are primarily based on Caucasian features. OBJECTIVE: To assess the validity of the first aesthetic scale for assessing the slope of the Asian forehead. A secondary objective was to correlate this scale with subject demographics and baseline characteristics. METHODS: During 2 validation sessions, 13 raters assessed full frontal and lateral facial images of female (n = 28; 56.0%) and male (n = 22; 44%) subjects. For each subject, the severity of forehead sloping was graded from 0 (convex forehead, optimal forehead volume) to 4 (concave forehead, very severe sloping). Raters also assessed the age of each subject and the estimated aesthetic treatment effort required to treat each subject. RESULTS: Inter-rater reliability was "substantial" with scores of 0.67 and 0.68 for the first and second validation sessions, indicating high reliability. BMI showed the highest correlation with the scale and was a significant predictor in the final regression model. CONCLUSION: This photonumeric assessment scale will be useful for assessing the slope of the Asian forehead in both clinical and research settings.

ABSTRACT

BACKGROUND: The Questionnaire on Pain caused by Spasticity (QPS) is a modular patient- and observer-reported outcome measure of spasticity-related pain (SRP) in children with cerebral palsy (CP). Originally developed for an English-speaking population, we conducted a psychometric validation of a recently developed Chinese language version of the QPS. METHODS: This was a prospective, observational study involving 137 children/adolescents with CP and upper and/or lower limb spasticity and their parents at three sites in China. Six QPS modules were used, three each for upper and lower limb SRP assessment: a patient self-report module; an interviewer-administered module used by site staff based on the cognitive, communicative, and motor abilities of a patient; and a parent/caregiver module administered for all children as an observer-reported outcome to complement the patient-reported outcome. If no assessment by the patient was possible because of age or cognitive impairments, only the parent/caregiver module was completed. Two visits with a 3-week interval provided data to evaluate and establish administrative ease of use, scoring of the QPS (factor analyses, Rasch analyses), reliability (Cronbach's α, intraclass correlation coefficient), validity (correlations with quality of life [PedsQL™], motor impairment [Gross Motor Function Classification System, Gross Motor Function Measure-66, Manual Ability Classification System], and spasticity [Ashworth Scale, Modified Tardieu Scale]). RESULTS: For most children, clinic staff reported no difficulties associated with general QPS use or deciding which module to use. Children (and parents) who reported more demanding activities also reported higher levels of associated SRP (or observed SRP behavior). Activity-related SRP items were combined for a total QPS score. Cronbach's α was low for child self-report, but was acceptable for interviewer-administered and parent reports on SRP. Test-retest reliability was high for all modules. Moderate-strong associations were frequently seen between QPS and quality of life, and were particularly strong in the child self-report group. Relatively weak associations were observed between QPS and motor impairment and spasticity. CONCLUSIONS: This first study was successful in providing initial evidence for the psychometric properties. Clinic staff were able to administer the QPS modules easily, and both children and parents were able to complete the designated QPS appropriately.

ABSTRACT

BACKGROUND: Décolleté aging includes skin dyspigmentation, laxity, and visible wrinkling. The development of globally accepted scales for the assessment of décolleté aging is essential for aesthetic research and patient evaluation. OBJECTIVE: To develop a set of grading scales for the objective assessment of décolleté aging criteria and establish the reliability and validity of these scales. MATERIALS AND METHODS: To describe age-related changes to the décolleté, 3 photonumeric grading scales were created and validated: décolleté wrinkles-at rest, décolleté wrinkles-dynamic, and décolleté pigmentation-at rest. Thirteen aesthetic experts rated photographs of the décolleté of 50 women at rest and at dynamic "hand-to-elbow" positions in 2 validation sessions. Responses were analyzed to assess interrater and intrarater reliability. RESULTS: Interrater and intrarater reliability were both "almost perfect" (≥0.81, intraclass correlation coefficient and weighted kappa) for décolleté wrinkles-dynamic, summary score for décolleté, and estimated age. Reliability was "substantial" (0.61-0.80) for all other décolleté assessments. There was high correlation between all décolleté scales, estimated age, and estimated aesthetic treatment effort. CONCLUSION: Consistent outcomes between raters and by individual raters at different time points confirm the reliability of the décolleté grading scales, indicating that they will be a valuable tool for use in clinical research and practice.

ABSTRACT

PURPOSE: To develop a patient-reported outcome measure for spasticity-related pain in children/adolescents (age 2-17 years) with cerebral palsy (CP), the 'Questionnaire on Pain caused by Spasticity (QPS).' METHODS: Using a semi-structured interview guide, concept elicitation interviews on spasticity-related pain in upper and lower limbs were conducted in 21 children and caregiver pairs. Data were used to modify initial QPS modules and develop six draft modules, which were subsequently refined and finalized in four consecutive cognitive interview waves (12 children and caregiver pairs). RESULTS: To accommodate the broad range in the children's communication skills, QPS child/adolescent modules were developed in both interviewer-administered and self-administered formats. With the additional parent modules, three QPS modules were developed for each of the upper and lower limb applications. Information gained from the parent/caregiver modules complements the child/adolescent assessment. Parents report observed signs and frequency of pain in the same situations used to capture the child/adolescent reports of pain severity (e.g., rest, usual daily activities, active mobilization, and physically difficult activities). Participating children/adolescents and parents/caregivers reported that the final QPS instruments were comprehensive, relevant to the child's spasticity-related experience, and easy to understand and complete. CONCLUSIONS: The QPS is a novel instrument for the assessment of spasticity-related pain in children/adolescents with CP that was developed with direct patient input. Its modules allow the use of this instrument in children/adolescents with varied levels of impairment and communication skills.

ABSTRACT

BACKGROUND: Marked platysmal bands in the neck are an unwelcome sign of aging. Botulinum neurotoxin type A has been used successfully to treat this indication, but there is a need for a validated tool for accurate assessment of dynamic platysmal bands to evaluate treatment efficacy objectively. OBJECTIVE: To develop a scale for objective assessment of dynamic platysmal bands and to validate its use in the clinical setting. METHODS: A new 5-point photonumeric assessment scale for platysmal bands was developed. Ten experts experienced in aesthetic dermatology used the scale to rate frontal and lateral neck photographs of 50 subjects in two separate validation cycles. Inter- and intrarater reliability of the scale was assessed. RESULTS: The scale comprises five ratings of platysmal band severity ranging from 0 (no relevant prominence of platysmal bands) to 4 (very severe prominence of platysmal bands). Interrater reliability was "almost perfect," with intraclass correlation coefficients of 0.81 for the first validation cycle and 0.82 for the second. Mean intrarater reliability was also high (0.89), with Pearson correlation coefficients ranging between 0.87 and 0.91. CONCLUSION: The new 5-point dynamic platysmal band photonumeric assessment scale is a valuable tool for use in the aesthetic clinical setting.

ABSTRACT

BACKGROUND: Twenty grading scales have been developed to assess age-related facial changes. Until now, the validity with regard to the patient's actual age and the clinical importance of combined measurement tools to describe facial aging was unclear. OBJECTIVE: To investigate the reliability and validity of a total face score and three global face assessment scales for estimated age, estimated aesthetic treatment effort, and signs of aging in the facial units. MATERIALS AND METHODS: Descriptive, reliability, correlation, and principal component analyses based on the assessment of 50 subjects by 12 raters using the 20 grading scales and the global face assessment scales. RESULTS: Inter- and intrarater reliability was high for the total face score and for the scales on estimated age and aesthetic treatment effort. Actual age was highly correlated with these three measures. Facial aging was indicated particularly by scales of the lower face. CONCLUSION: The aesthetic grading scales and global scales on estimated age and aesthetic treatment effort are reliable and valid instruments. The results suggest that a more-comprehensive evaluation of the human face and its age-related changes can help to identify important areas of facial aging and to define optimal aesthetic treatment strategies.

ABSTRACT

BACKGROUND: Age-related upper face changes such as wrinkles, lines, volume loss, and anatomic alterations may affect quality of life and psychological well-being. The development of globally accepted tools to assess these changes objectively is an essential contribution to aesthetic research and routine clinical medicine. OBJECTIVE: To establish the reliability of several upper face scales for clinical research and practice: forehead lines, glabellar lines, crow's feet (at rest and dynamic expression), sex-specific brow positioning, and summary scores of forehead and crow's feet areas and of the entire upper face unit. METHODS AND MATERIALS: Four 5-point photonumerical rating scales were developed to assess glabellar lines and sex-specific brow positioning. Twelve experts rated identical upper face photographs of 50 subjects in two separate rating cycles using all eight scales. Responses of raters were analyzed to assess intra- and interrater reliability. RESULTS: Interrater reliability was substantial for all upper face scales, aesthetic areas, and the upper face score except for the brow positioning scales. Intrarater reliability was high for all scales and resulting scores. CONCLUSION: Except for brow positioning, the upper face rating scales are reliable tools for valid and reproducible assessment of the aging process.

ABSTRACT

BACKGROUND: The improvement of aesthetic treatment options for age-related mid face changes, such as volume loss, and the increase in patient expectations necessitates the development of more-complex and globally accepted assessment tools. OBJECTIVE: To develop three grading scales for objective assessment of the infraorbital hollow and upper and lower cheek fullness and to establish the reliability of these scales for clinical research and practice. METHODS AND MATERIALS: Three 5-point rating scales were developed to assess infraorbital hollow and upper and lower cheek fullness objectively. Twelve experts rated identical mid face photographs of 50 subjects in two separate rating cycles using the mid face scales. Test responses of raters were analyzed to assess intra- and interrater reliability. RESULTS: Interrater reliability was substantial for the infraorbital hollow, upper cheek fullness, and lower cheek fullness scales. Intrarater reliability was high for all three scales. Both of the cheek fullness scales yielded higher reliabilities when three rather than two views were used to assess the volume changes of the cheek. CONCLUSION: The mid face scales are reliable tools for valid and reproducible assessment of age-related mid face changes.
