Objective:
The aim was to provide epidemiological and clinical data on patients with orofacial clefts in Lower Saxony in Germany.
Materials And Methods:
The records of 404 patients with orofacial clefts treated surgically at the University Medical Center Goettingen from 2001 to 2019 were analyzed in this retrospective study. Prevalence of orofacial clefts in general, orofacial clefts as manifestation of a syndrome, sex distribution, and prevalence of different cleft types was evaluated and associated with the need for corrective surgery, family history, pregnancy complications, and comorbidities.
Results:
The prevalence of orofacial clefts for Goettingen in Lower Saxony was 1:890. 231 patients were male and 173 were female. CLP was most common (39.1%) followed by CP (34.7%), CL (14.4%), CLA (9.9%), and facial clefts (2%). The left side was more frequently affected and unilateral cleft forms occurred more often than bilateral ones. Almost 10% of the population displayed syndromic CL/P. 10.9% of all patients had a positive family history regarding CL/P, predominantly from the maternal side. Pregnancy abnormalities were found in 11.4%, most often in the form of preterm birth. Comorbidities, especially of the cardiovascular system, were found in 30.2% of the sample. 2.2% of patients treated according to the University Medical Center Goettingen protocol corrective surgery was performed in form of a velopharyngoplasty or residual hole closure.
Conclusions:
The epidemiological and clinical profile of the study population resembled the expected distributions in Western populations. The large number of syndromic CL/P and associated comorbidities supports the need for specialized cleft centers and interdisciplinary cleft care.
