What is kernahan classification?

The area affected by the cleft is labeled from 1-9, each of which represents a different anatomical structure: 1: Right lip; 2: Right alveolus; 3: Right premaxilla; 4: Left lip; 5: Left alveolus; 6: Left premaxilla; 7: Hard palate; 8: Soft palate; 9: Submucous cleft. Source publication.

What is the Lahshal classification for cleft deformity?

There has been a general move to adopt a simple classification system for clefts. The LAHSHAL code is often used as the preferred classification system by cleft surgeons (“L” = lip, “A” alveolus, “H” hard palate, “Soft palate”). It is compatible with ICD10 and allows clefts to be coded for computer use.

What is the main cause of cleft palate?

Cleft lip and cleft palate are thought to be caused by a combination of genes and other factors, such as things the mother comes in contact with in her environment, or what the mother eats or drinks, or certain medications she uses during pregnancy.

How do you classify cleft lip and palate?

Group I – Defects of the lip or alveolus. Group II – Clefts of the secondary palate (hard palate, soft palate, or both) Group III – Any combination of clefts involving the primary and secondary palates.

What is a NAM for cleft palate?

Nasoalveolar molding (NAM) is a presurgical therapy used to reduce the size of the cleft or palate deformity of the lip, gum and nose before surgical repair. The goal of NAM is to reduce the size of the cleft deformity of the lip, gum and nose (oronasal deformity) before surgical repair.

Can you have 2 Uvulas?

What is Bifid Uvula? A bifid uvula, also known as a cleft uvula, is a uvula that is split in two. The distance between the two halves of the uvula may be narrow or wide. A bifid uvula may be an isolated, benign finding, or it may be related to submucous cleft palate.

What is the most severe type of cleft?

The most severe form involves the entire secondary palate, seen as a gap in the palate from the tip of the uvula to the incisive foramen. This is the most overt of the incomplete palate clefts.

Is cleft lip hereditary or environmental?

There is remarkable heterogeneity by ancestry in the relative contributions by genes found with common variants contributing to CLP. There is evidence that environmental factors have a role in CLP risk and interactions of the environment with certain genetic variants have been identified.

Are cleft palates hereditary?

The causes of cleft lip and cleft palate (or both) are unknown, although hereditary (genetic) factors sometimes play a small role. A cleft lip or cleft palate (or both) is not caused by anything the parents did or did not do during the pregnancy.

What are the three main cleft groups?

Abstract. Cleft lip can be classified into three groups according to the fissure site: unilateral cleft lip, bilateral cleft lip, and median cleft lip [1].

What are the two types of cleft lip?

Types of cleft lip Incomplete unilateral cleft lip: An opening on one side of the lip that does not extend into the nose. Complete unilateral cleft lip: An opening on one side of the lip that extends up into the nose and typically involves the gum ridge and palate.

What’s new in Kernahan’s striped y classification?

A modification of Kernahan’s striped Y classification is proposed that addresses these problems. This system was applied to 150 cleft patients, and it was found that it was able to describe all varieties of clefts encountered. In contrast, the Kernahan system could only describe 74.7 percent of the patients adequately. ( Plast. Reconstr.

What percentage of patients does the Kernahan system accurately describe?

In contrast, the Kernahan system could only describe 74.7 percent of the patients adequately. ( Plast. Reconstr. Surg. 102: 1842, 1998.) Plastic and Reconstructive Surgery102 (6):1842-1847, November 1998.
