Congenital fistulas of the lip are commonly found in the lower lip and accompany cleft lip. They are seen as a symptom of Van der Woude syndrome, which is predominantly hereditary. In contrast, congenital fistulas of the upper lip are rare. A number of hypotheses have been proposed to explain the pathogenesis of fistulas of the upper lip, including fusion failure of facial prominences and absen...

Lip print: The science under which lip prints study referred as Cheiloscopy. Establishing a person’s identity is a very important process in civil and criminal cases. . Lip prints help in personal identification and criminal investigation is very much important as his evidence would be very much useful in law and justice. Dental identification, fingerprint and DNA comparisons are probably the m...

[Purpose] This study aimed to investigate the effect of neuromuscular electrical stimulation (NMES) on lip strength and closure function of patients with dysphagia after stroke. [Subjects and Methods] Eight patients with dysphagia were recruited. NMES was applied to the orbicularis oris muscle. All the participants received NMES for 30 min/d, 5 d/wk, for 4 weeks. Lip strength was measured using...

The lips are regarded as a paired organ for audiovisual speech communication that modulates speech sound and facial shape together in speech production. Despite the long research, the mechanism of lip protrusion is still an open question. This study aims at exploring physiological mechanisms of lip protrusion based on muscle visualization and finite element simulation of lower lip deformation. ...

This paper addresses the problem of lip segmentation in color space that is a crucial issue to a successful lip-reading system. We present a new segmentation approach to lip contour extraction by taking account of the maximum a posterior Markov random field (MAPMRF) framework. We first examine various color models and select a simple color transform derived from LUX and 1976 CIELAB color space ...

introduction: anthropometry (morphometry of the human) is measurement of linear and angular dimensions of the human body. since the anthropometric parameters which are based on age, sex, geographical location and ethnic characteristics of the human species are different, therefore, anthropometric studies of population by age and sex should be done separately. methods: in this study, anthropomet...
