Pronunciation: [hˈe͡ɪzɪlˌɪp] (IPA) 
The correct spelling of the word "Hazelip" is often debated. The word refers to a facial deformity where the upper lip is split. The IPA phonetic transcription for this word would be /ˈheɪzəlɪp/. The first syllable is pronounced like "hey" with a "z" sound in the middle, and the second syllable is pronounced like "lip". Some spell the word as "harelip", but "hazelip" is the more commonly accepted spelling.
Hazelip, or cleft lip, is a congenital condition characterized by a gap or split in the upper lip. This separation occurs when the tissues and muscles of the baby's lip fail to fuse together properly during fetal development. The result is a visible cleft or notch in the upper lip, which may extend towards the nose. Hazelip can vary in severity, with some cases displaying only a small notch, while others present with a more extensive opening that can reach the nostril.
The exact cause of hazelip is not fully understood, but it is thought to involve a combination of genetic and environmental factors. Certain genetic mutations or abnormal development of the face during early pregnancy can contribute to the occurrence of hazelip. Additionally, factors such as maternal smoking, alcohol consumption, or exposure to certain medications or infections during pregnancy may increase the risk.
Hazelip can lead to difficulties in feeding, speech, and hearing, as well as potential oral health issues. It is typically diagnosed shortly after birth based on physical examination. Treatment for hazelip often involves surgical repair, with the goal of closing the gap and restoring normal lip function and appearance. Surgery is usually recommended within the first year of life in order to minimize potential complications and to facilitate proper speech development.
Overall, hazelip is a congenital condition characterized by a split or notch in the upper lip that can be effectively addressed through surgical intervention and proper medical care.
The word Hazelip is derived from the Middle English term haselep, which originated from the Old English word haeslep. It is a compound word that combines haesel (hazel tree or hazelnut) and lep (meaning a lip or lump). Therefore, Hazelip originally referred to a deformity or abnormality of the lip, often resembling a split or cleft, that had a likeness to a hazelnut or hazel tree. This term has however been replaced today with the more medically accurate term cleft lip.
