No full textMicroform cleft lip (MCL), also called congenital healed cleft lip or cleft lip "frustré", is a rare congenital anomaly. MCL has been described as having the characteristic appearance of a typical cleft lip which has been corrected in utero. We present a girl with bilateral microform cleft lip associated with a preauricular sinus and bilateral camptodactyly.peer-reviewe
A new bottle design to correct mechanical defect during feeding in cleft lip and palate babies
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel UniversityBabies with cleft lip and palate which is a common craniofacial deformity suffer from feeding problem which interfere with their growth and development and render the subsequent corrective surgery and also endure their daily suffering during the feeding time. This thesis reports the design of a new bottle feed to overcome this problem. Also a clinical study was preformed to study the patterns of baby feed in cleft lip and palate babies to support the use of the bottle feeding for this group of babies
Dictionary-based lip reading classification
No full textVisual lip reading recognition is an essential stage in many multimedia systems such as “Audio Visual Speech
Recognition” [6], “Mobile Phone Visual System for deaf people”, “Sign Language Recognition System”, etc.
The use of lip visual features to help audio or hand recognition is appropriate because this information is robust
to acoustic noise. In this paper, we describe our work towards developing a robust technique for lip reading
classification that extracts the lips in a colour image by using EMPCA feature extraction and k-nearest-neighbor
classification. In order to reduce the dimensionality of the feature space the lip motion is characterized by three
templates that are modelled based on different mouth shapes: closed template, semi-closed template, and wideopen
template. Our goal is to classify each image sequence based on the distribution of the three templates and
group the words into different clusters. The words that form the database were grouped into three different
clusters as follows: group1(‘I’, ‘high’, ‘lie’, ‘hard’, ‘card’, ‘bye’), group2(‘you, ‘owe’, ‘word’), group3(‘bird’)

The soft-source impedance of the lip-reed : experimental measurements with an artificial mouth
No full textMost theoretical descriptions of the brass instrument lip-reed consider the acoustical condition at the lips to be a closed, rigid termination, corresponding to a unitary reflectance. This assumption is carried through to many computational models as well. In reality, the protrusion of the player's lips into the mouthpiece causes a periodic shortening/extension of the acoustical tube downstream, an effect sometimes but not always incorporated into such models. Of interest here is the absorption properties of the lip termination, the so-called 'soft source impedance'. This provides a further modification to the boundary condition at the lips, since the soft, deformable nature of the lips are likely to cause some extra damping of the acoustic standing wave. Measurements are presented to demonstrate this damping effect using an artificial mouth. This is achieved through measurements of the lip reflectance from downstream of the lips, from where it is shown that the reflectance shows a dip at the peak absorbance frequency of the lips. The frequency of the absorbance is shown to vary as the lip parameters are changed
Dentofacial Characteristics Of Malay Patients With Repaired Cleft Lip And Palate In Kelantan [RD524. B138 2005 f rb].

Pesakit CLP mengalami masalah makan, bernafas, infeksi telinga tengah, masalah psikososial dan lain-lain. Rawatannya memerlukan penglibatan pelbagai disiplin yang bermula dari hari pertama dilahirkan dan berterusan hingga peringkat umur 20 ke 21 tahun.
Cleft lip and palate (CLP) is the most common congenital facial defect. Patients with CLP suffer from feeding, breathing, middle ear infections as well as psychosocial and other problems. The treatment requires interventions from multiple disciplines which start from the first day of life and continue up to the age of 20 to 21 years
Causes Of Lip Twitching & Solutions
No full textLip Twitching A weird inclination or development in the lip can be seen severally. The lip may tremble, shiver, consume, or contract automatically. The sensation can be irritating, humiliating, and alarming. The lips are made out of muscles covered by a bodily fluid film and are made to move by the terminating of the facial nerves.

Complementing surgical with biomedical and engineering methods to evolve lip and nose reconstruction
No full textFacial integrity and self-perception are intimately related to each other. A facial defect therefore affects a patient in his physical and psychosocial health as well. Every reconstructive method exhibit certain imperfections or burden for the patient, which motivates the surgeon’s to strive for improvements. While many imperfections can be improved by refinements of the surgical techniques, some aspects might be not solvable by surgical principles alone. At that stage, biomedical and engineering methods should be considered to complement the surgical treatment for further improvements.
We developed and explored a variety of biomedical and engineering methods to overcome shortcomings of current lip-nose reconstruction techniques.
The unknown shape of a missing nose was computed from a morphable face model that comprise the facial shape information of 200 healthy individuals. It led to a more natural shape planning than by hand carving. A biocompatible facial prosthesis was then made out of polyamide using computer assisted design and manufacturing. Alternatively to facial prosthesis large facial defects can be covered by means of tissue transfer from a distant body site performing a microsurgical vascular anastomosis. In this area, the importance to develop and use monitoring devices and pharmaceutical drugs for anastomosis patency remained unclear. We assessed therefore the current practice for microsurgical head and neck tissue transfer in clinics of Germany, Switzerland and Austria. There was a high variability with equal success rate, technical monitoring devices and pharmaceutical drugs seemed to have a negligible effect on the success rate, while the surgical anastomosis having the main effect. To repair small naso-labial defects of inborn cleft lips, the use of the adjoining tissue is sufficient. However, since both lip parts contain a labial artery of normal thickness they could be as well unified by a microsurgical anastomosis, however its biological rational needed exploration. We measured the lip artery blood flow and nose-lip microcirculation in cleft lip patients before and after surgical repair and in normal using laser Doppler flowmetry and white light tissue spectrometry. We found no circulation deficit in cleft patients and therefore no need to strive for a surgical anastomosis. Nonetheless, since blood flow is a precondition for growth and development, visible vessels in the surgical field should be preserved best possible. We therefore studied the intraoperative vascular anatomy for constant vascular findings. A perforating artery of the Musculus transversus nasalis was identified at the nasal ala on the cleft side, which could be constrantly preserved after it became aware.
The aim to refine a surgical treatment should not exclusively focus on the surgical technique but need also consider the burden of the entire treatment plan. More than 95% of the European cleft surgery centers use 2 to 4 surgeries to close the cleft of the lip, alveolus, hard, and soft palate –considering that this optimizes growth of the cleft maxilla. But facing the burden of repetitive surgeries for patient and family, Dr. Honigmann introduced in Basel 1991 the cleft repair in one single operation at “one-stage”. We were now able to assess the long-term growth effect of this procedure, which showed the same growth results as compared to multi-stage procedure. But when compared to normal, 20% to 45% of the cleft patients still showed a growth deficit that would require surgery to normalize the dental relation and facial profile. The orthognathic surgery rate in cleft patients from the literature ranges also widely from about 20% to 45%, whatever surgical technique and treatment plan is applied. It is therefore doubtful that by surgical means alone the growth deficit can be avoided. This prompted us to assess the in-vitro and in-vivo osteogenic capacity of stem cells from the umbilical cord Wharton’s jelly (WJMSC) under fully defined conditions allowing for clinical translation. Due to prenatal ultrasound the cleft lip malformation is frequently known before birth, and the umbilical cord could thus serve as an autologous stem cell donor site without any harvesting morbidity. Both, Osteogenically differentiated WJMSCs and WJ tissue biopsies produced a mineralized extracellular matrix. The expression of genes of osteoblastic lineage increased significantly after 3 weeks of osteodifferentiation. Although the WJMSCs formed in-vitro a dense collageneous matrix with signs of osteoblastic differentiation, no mature bone tissue was found after 8 weeks after subcutaneous implantation in immunoincompetent mice. Further in-vivo tests are therefore necessary applying more favorable bone forming conditions by using ostegenic predifferentiated cells and implantation into a bone defect.
In sum, biomedical and engineering methods have been applied to solve surgical problems or to establish new therapeutic strategies where conventional lip and nose reconstruction methods reach their limits. This has been demonstrated at different lip and nose reconstructive levels reaching from prosthetics, over microsurgery, to stem cell tissue engineering
