“…Se han descrito múltiples métodos de estudio de las características morfológicas de los labios, los cuales incluyen: antropometría labial a través de impresiones labiales Chiandussi et al, 2007), resonancia magné-tica, estereografía tridimensional (Sawyer et al) y la fotografía clínica (Edler et al, 2011;Davis et al, 2010;Cattoni & Fernandes, 2009). …”

RESUMEN: El objetivo de esta investigación fue determinar diferencias de dimorfismo sexual de las características de labios de hombre y mujeres mestizos colombianos a través de análisis fotogramétrico. Se evaluaron fotografías frontales de 120 individuos mestizos sin alteraciones congénitas o adquiridas de los labios, tomadas en relación 1:1. A través del uso de puntos antropométricos en la vista frontal, se evaluaron las dimensiones: Grosor del Labio Superior (Sn-Stms), Grosor del bermellon superior (Stms-Ls), Grosor del Labio Inferior (Stmi-Sml), Grosor del bermellon Inferior (Stmi-Li) y Ancho bicomisural (Chd-Chi), con la ayuda del software J image (NIH). El análisis estadístico utilizó la prueba U Mann-Whitney usando el software SPSS 17.0, para determinar diferencias entre los dos sexos en todas las variables. No se encontraron diferencias estadísticamente significativas en la longitud del bermellón del labio superior (Stms-Ls) ni en la longitud del bermellón del labio inferior (Stmi-Li). Se encontraron diferencias estadísticamente significativas (p<0,001) en Grosor del Labio Superior (Sn-Stms), Grosor del Labio Inferior (Stmi-Sml) y Ancho bicomisural (Chd-Chi). Estas medidas fueron mayores en individuos mestizos de género masculino. Existe dimorfismo sexual en el ancho bicomisural, longitud de labio superior e inferior en Colombianos Mestizos.

Facial biometrics of peri-oral changes in Crohn’s disease

et al. 2013

Crohn's disease is a chronic relapsing and remitting inflammatory condition which affects any part of the gastrointestinal tract. In the oro-facial region, patients can present peri-oral swellings which results in severe facial disfigurement. To date, assessing the degree of facial changes and evaluation of treatment outcomes relies on clinical observation and semi-quantitative methods. In this paper, we describe the development of a robust and reproducible measurement strategy using 3-D facial biometrics to objectively quantify the extent and progression of oro-facial Crohn's disease. Using facial laser scanning, 32 serial images from 13 Crohn's patients attending the Oral Medicine clinic were acquired during relapse, remission, and post-treatment phases. Utilising theories of coordinate metrology, the facial images were subjected to registration, regions of interest identification, and reproducible repositioning prior to obtaining volume measurements. To quantify the changes in tissue volume, scan images from consecutive appointments were compared to the baseline (first scan image). Reproducibility test was performed to ascertain the degree of uncertainty in volume measurements. 3-D facial biometric imaging is a reliable method to identify and quantify peri-oral swelling in Crohn's patients. Comparison of facial scan images at different phases of the disease revealed precisely profile and volume changes. The volume measurements were highly reproducible as adjudged from the 1% standard deviation. 3-D facial biometrics measurements in Crohn's patients with oro-facial involvement offers a quick, robust, economical and objective approach for guided therapeutic intervention and routine assessment of treatment efficacy on the clinic.

Lip impressions: a new method for monitoring morphological changes in orofacial granulomatosis

Abstract: Serial lip impressions appear to be reliable for routine quantification of morphological changes of the lips in OFG patients. We present a new reproducible and sensitive method for assessing changes in lip size in response to treatment in OFG.
