Impact of endocrine disorders associated with cleft lip and palate.

Abstract

Background: Any impediment to the development of midline structures i.e. hypothalamus, pituitary and oral cavity may cause anatomical and functional issues. We aimed to determine the association of endocrine disorders with anatomic defects of midline structures i.e. cleft types and syndromes, as well as their impact on postoperative intensive care unit (ICU) admissions and complications.

Methods: A total of 6000 patients from the Cleft Lip and/or Palate (CLP) Treatment Center between September 2014 - February 2022 were included. Patients with physical findings or biochemistry that may indicate endocrine disorders were examined by the Division of Pediatric Endocrinology. Data concerning sex, operation age, cleft types, coexisting endocrine disorders, syndromes, echocardiography, postoperative complications as well as postoperative intensive care unit (ICU) admissions were recorded.

Results: The study group consisted of 78 patients with endocrine disorders, with a mean follow-up time of 59±7 months. One hundred and nine CLP operations were performed. The most common endocrine disorders coexisting in CLP patients were hypothyroidism (44.8%) and growth hormone (GH) deficiency (14.1%). Of the patients, 29.4% had genetic syndromes. The median age of operation in patients with endocrine disorders was 5 months (Q1-Q3: 4-8 months) for cleft lip and 15 months (Q1-Q3: 12-20 months) for cleft palate repair. Of the patients with CLP and endocrine disorders, 24% required postoperative ICU admission. Age of operation and ICU admission rates were higher compared to the general population of patients with CLP in our center (p<0.01).

Conclusions: Endocrine disorders, particularly hypothyroidism and GH deficiency, are frequent in CLP. Furthermore, our data suggest that endocrine disorders may complicate the postoperative course. Thus, investigation of these problems is crucial for appropriate treatment as well as adopting measures to successfully manage the postoperative course.
