BACKGROUND Cleft lip with or without cleft palate (CL/P) is one of the most common craniofacial malformations, with a complex and multifactorial etiology. Because of the genetic heterogeneity of facial clefts, the aim of this study was to investigate the contribution of previously reported candidate genes and chromosomal loci to the risk of CL/P in the(More)
BACKGROUND Non-syndromic isolated cleft lip with or without cleft palate (NCL/P) is a common congenital anomaly in humans, the aetiology of which is complex and associated with both genetic and environmental factors. It has been reported that maternal nutritional factors are likely to play a major role in development of NCL/P in the embryo. OBJECTIVE As(More)
The CDH1 gene plays an important role during carcinogenesis and craniofacial morphogenesis. Germline mutations in this gene have been described in families presenting syndromic diffuse gastric cancer and orofacial clefts. The aim of this study was to evaluate the association between nucleotide variants of CDH1 and the risk of non-syndromic cleft lip with or(More)
Treacher Collins syndrome (TCS) is an autosomal dominant disorder of craniofacial development. The major features of the disease include midface hypoplasia, micrognathia, microtia, conductive hearing loss and cleft palate. Current procedures of surgical treatment of TCS are discussed and novel findings concerning the genetic background of TCS are described.(More)
INTRODUCTION Parry-Romberg syndrome is an extremely rare disease characterized by the slow atrophy of the face involving the skin, subcutaneous tissue, fatty tissue, muscles, and even bones. The cause of the disease is unknown. The onset is slow and it begins usually during the first 2 decades of life, more often between the ages of 5 and 15. The purpose of(More)
UNLABELLED Eyelid tumors constitute about 40% of all cancers located in the orbital region. Most commonly, they are basal cell carcinomas, in 90% of cases located in the lower eyelid and medial canthus. The purpose of our study was to present the management and to overview the results of surgical treatment of eyelid tumors. MATERIALS AND METHODS One(More)
Vascular tumours and vascular malformations are common vasculose anomalies characteristic for dissimilar clinical course, specific biological as well as immune cytological and histological properties. Vascular lesions classification system and their detailed division into groups and subgroups were elaborated and implemented in Rome, in 1996, during meeting(More)
Secondary osteoplasty by means of autogenic spongy bone grafting is the most common procedure used in the reconstruction of the continuity of the maxillary alveolar process. The aim of the study was to analyze retrospectively the effect of certain factors on the course of the bone graft healing process in patients with unilateral complete clefts of the lip,(More)
Morphology, genetic conditioning, terminology, and the principles of treatment of Treacher Collins syndrome have been presented on the basis of our own material, as well as review of literature. Fifty patients (27 males, 23 females) were operated on at the Hospital of Plastic Surgery in Polanica Zdrój from 1976 to 2005. The patients were first seen when(More)
