Clinical and Descriptive Study of Orofacial Clefts in Colombia: 2069 Patients From Operation Smile Foundation

Root Curvature in Non-Syndromic Oral Clefts: A Case-Control Study in a Brazilian Population

OBJECTIVE

This study assesses the degree of root curvature in patients with non-syndromic cleft lip and/or palate (NSCL/P).

DESIGN

Retrospective. Case-control study.

SETTING

Root curvature was assessed in lower premolars and molars in 800 panoramic radiographs: 400 from patients with cleft and 400 from healthy control individuals. Root curvature was classified according to its angulation, as well as its apical, medial, or coronal localization.

RESULTS

The frequency of mild curvature in the NSCL/P group compared to the control group was higher in premolars especially in the left second premolar in cleft palate (OR: 6.91; 95% CI: 3.23-14.77; P < .0001). The frequency of moderate curvature in molars was significantly higher in the cleft group, with the highest risk in the right first molar in the cleft lip group (OR: 2.74; 95% CI: 1.67-4.52; P < .0001). Inclination was more frequently observed in the apical third of the root in the group with cleft, whereas for the control group, the curvature was more frequent in the medial third. In patients with cleft, the OR of curvature in the apical third was significant in premolars (left lower second premolar: Cleft lip, OR: 1.91; 95% CI: 1.04-3.52; P = .03; right lower second premolar: Cleft lip, OR: 1.91, 95% CI: 1.04-3.50; P = .03, cleft lip and palate, OR: 1.75; 95% CI: 1.12-2.73; P = .01).

CONCLUSION

The results of the current study indicate differences in root curvature in patients with non-syndromic cleft lip and/or palate, which should be considered during the dental treatment planning of patients.

Cleft lip and palate risk factors among otorhinolaryngology: Head and neck surgery patients in two hospitals

Cleft lip and/or palate is the most prevalent type of head and neck deformity, accounting for 65% of cases. The occurrence of this condition is influenced by both genetic and environmental factors. Cleft defects are classified into 2 types: syndromic cleft lip and palate syndrome and non-syndromic cleft lip and palate syndrome. Cleft lip with or without cleft palate is the most common type of cleft defect, and the surgical repair is the primary treatment option for patients. Our study was a retrospective case-control study that included 132 cases of patients with cleft defects and 132 healthy babies without cleft defects serving as controls. Personal information, including the name, age, and origin of the participants, was collected. Additionally, we collected information on all potential risk factors, including medical history, daily habits, consanguinity between parents, and family history. Information was collected in Excel and analyzed using the Statistical Package for Social Sciences and a Chi-Square test was performed to determine the results and their relationship to cleft lip and palate. Our study identified various risk factors that have a significant association with cleft lip and palate with a P-value <5% in addition to factors that are not considered risk factors. Using relative risk analysis, we were able to rank the top 5 most significant and influential risk factors. The most impactful factor was not taking folic acid during pregnancy. The primary risk factors associated with cleft lip and palate include a family history of the condition, lack of folic acid supplementation, maternal age over 35 years, and high temperatures exceeding 39 °C. Consequently, we recommend that mothers who intend to conceive should take folic acid supplements at a dose of 0.4 to 0.8 mg during the initial trimester of pregnancy. Additionally, we advise careful monitoring of all risk factors, particularly during the first trimester of pregnancy.

Epidemiological and Spatiotemporal Descriptive Analysis of Patients with Nonsyndromic Cleft Lip and/or Palate: A 12-Year Retrospective Study in Southern Iran

Objectives

The current study is aimed at evaluating epidemiological characteristics and spatiotemporal distribution of cleft lip and/or palate (CL/P) in the south of Iran.

Methods

Data were extracted from the 1840 medical records of patients who were referred to the Cleft Lip and Palate Center of Shiraz University of Medical Sciences, from January 1, 2011, to September 1, 2022. The collected variables included demographic data (gender, birth date and season, place, birth order, and weight), cleft types and the subtypes, parental information (health status, education level, marital status, and age during the pregnancy), and other basic parameters. The chi-square test at a significance level of 0.05 was used to analyze collected data. The geographic information system (GIS) analysis was also used for analyzing the spatial distribution of CL/P patients.

Results

Based on our inclusion criteria, 1281 nonsyndromic patients were included in this study. The most common type was cleft lip and palate (CLP) with 48.32%, whereas cleft palate (CP) and cleft lip (CL) accounted for 40.75% and 10.93% of the patients, respectively. There was a progressive increase in the frequency of all types of clefts, and most of them were male (P ≤ 0.001). The urban population outnumbered the rural ones in all provinces. Parents were mostly healthy (>80%) with low educational status (47.5%). Most born CL/P patients were from consanguineous marriages (58.9%), especially between first-degree relatives. A majority of CL/P patients (73.1%) were born in the first two gestations with a birth weight of 2500-4000 g (77.4%). Most infants with CL/P (84.3%) were born from mothers who had at least one of the predisposing factors.

Conclusion

In this study, the frequency of cleft types and subtypes was similar to the existing literature. However, high rate of consanguineous marriage, especially between first-degree relatives, was the most notable feature of this population.
