Prevalence of cleft lip and/or palate in children from Lodz between years 1981–2010

Abstract

Congenital malformations constitute a serious problem of both medical and social nature. Cleft lip and/or palate represent the most common congenital anomaly of the face that is why it is essential to know the real frequency of the described phenomenon. The aim of this paper is to determine the frequency of cleft lip and/or palate and the types of malformations that occurred in Lodz city between the years 1981-2010. Our clinic has been carrying on the studies concerning the incidence of cleft lip and/or palate since 1981. The Polish Registry of Congenital Malformations has been operating in Poland since 1 April 1997. The team has managed to obtain data, from the Registry, concerning the total number of all live born infants and the number of children with cleft lip and/or palate, who were born in Lodz, between 1998 and 2010. In years 1981-2010, 319 children, in 210 952 live born infants, were born with cleft lip and/or palate in Lodz. The isolated cleft palate was observed more frequently in girls and the unilateral cleft of lip and palate in boys. In all three decades palate clefts are more common whereas bilateral lip, alveolus and palate clefts are more infrequent. A small tendency to decrease in actual cleft lip and/or palate frequency among children, in the period of 30 years, is observed in Lodz. Over the years it has still been observed that the isolated cleft palate is the most common type of defect.

Prevalence of cleft lip and/or cleft palate in Guangdong province, China, 2015–2018: a spatio-temporal descriptive analysis

“…31 For spatial distributions of the prevalence, we observed spatial heterogeneity of prevalence of cleft lip and/or palate across the study period in Guangdong province. For the prevalence of the disease in the world, previous studies showed that the figure was quite different, 8 which indicated that the distribution of the disease was unbalanced and there existed spatial heterogeneity globally. 28 For example, the prevalence was relatively high in East Asia and the pacific compared with other regions in the world.…”

“…7 In many other regions, data on cleft lip and palate cases are of poor or incomplete quality, often lacking information on important variables such as gender and severity of morphological abnormalities, the published data on the prevalence of cleft lip and/or cleft palate from different parts of the world are quite different. 8 A previous study revealed that the African population had the lowest incidence of the disease, which is about 0.4/1000; in India, the average prevalence index of this disease was 0.398/1000 from 2007 to 2011. 9 Europe's incidence is about 1/1000; Asia and South Americas have relatively a high incidence of about 2/1000.…”

“…Furthermore, the different methods of data collection may have a potential impact on the research results. 8 This present study is one of a few studies including a large number of perinatal infants to describe the spatiotemporal characteristics of cleft lip and/or palate in south China. The findings of this study could help to understand the epidemiological characteristics of the diseases and provide reliable descriptive material for the subsequent research of the disease.…”

Outcomes of an international volunteer surgical project for patients with cleft lip and/or cleft palate: A mission in developing Laos

“…Cleft lip and/or palate (CL/P) is a common birth defect of complex etiology. Asian populations have the highest reported birth incidence of 1/500 or higher (Natsume et al 2000;Seto et al 2003;Cooper et al 2006), while the reported incidence in European derived populations is around 1/1100 (Antoszewski and Fijałkowska 2016), and the reported incidence in African derived populations is 1/2500 (Ekanem et al 2008). There are no reports of epidemiological studies on congenital anomalies such as CL/P in the Lao People's Democratic Republic (Laos).…”

“…Em relação ao fenótipo, as fissuras de palato foram mais frequentes entre as mulheres e a fissuras de lábio isolada e de lábio com palato predominaram nos homens, características que corroboram os relatos de conjuntos de dados nacionais e mundiais (ANTOSZEWSKI;FIJAŁKOWSKA, 2016;COUTINHO et al, 2009;CUOZZO et al, 2013;FERRARI-PILONI;JESUÍNO, 2021;HLONGWA;LEVIN;RISPEL, 2019;IMPELLIZZERI et al, 2019;MARTELLI et al, 2012;MENEZES et al, 2010;PACÁKOVÁ et al, 2016;PANG;BROYLES;REDETT, 2013).
