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 thallwitz classification of cleft?
Thallwitz Classification L = Lip – 1/3 or 2/3 or 3/3 A = Alveolar cleft – 1/3 or 2/3 or 3/3 H = Hard palate cleft – 1/3 or 2/3 or 3/3 S = Soft palate cleft – 1/3 or 2/3 or 3/3. 29.
What is a veau 2 cleft palate?
Veau-II cleft palate: A midline cleft of the velum (soft palate) and secondary hard palate (posterior to the incisive foramen), with intact primary palate (anterior to the incisive foramen)
What is Premaxillary triangle?
From the coronal view of the face, the transducer is tilted to obtain the 2 angulated nasal bones, forming an inverted V shape. The V is completed into a triangle by imaging the premaxillary bone, which forms the base of the V. We have named this triangle the PMT.
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 a Class 3 cleft lip and palate?
Veau Class I: Incomplete cleft, soft palate only (no unilateral/bilateral designation) Veau Class II: Hard and soft palate, secondary palate only (no unilateral/bilateral designation) Veau Class III: Complete unilateral cleft including lip (primary and secondary palates)
What is the difference between Pierre Robin syndrome and sequence?
Pierre Robin syndrome (PRS) — also called Pierre Robin sequence — is a condition in which your baby has a small jaw (micrognathia), a tongue that falls back toward the throat (glossoptosis) and upper airway obstruction. Infants with the condition also commonly have an opening in the roof of the mouth (cleft palate).
What is PMT in sonography?
PMT means pre maxillary triangle and it is as of late found as an early diagnosis for one sided cleft lip and palate. This is basically non fusion of the upper part of the mouth of the baby.
What is Simonart’s band?
This band is a tissue originating from a supplementary growth center of the maxillary process, called maxillary prime, which grows to form a bridge between the premaxilla and the lateral nasal prominence. 2. The prevalence of Simonart’s band in patients with unilateral cleft lip and palate is approximately 20%.
What are the two types of cleft lip?
A cleft lip can be on one side (unilateral) or both sides (bilateral) of the upper lip. Cleft lip can occur alone, or can occur with a cleft palate.
What are the different types of cleft?
These are: Incomplete cleft palate: Opening in the back of the mouth, called the soft palate. Complete cleft palate: Opening in the front and back of the mouth, or the soft and hard palates. Submucous cleft palate: Muscles within the soft palate are separated or cleft but the skin or mucous membrane is closed.

What is the LAHSHAL system for CL/P?
The LAHSHAL system can describe over 12,000 combinations (of anatomy and severity) for CL/P. As such, it is extremely detailed. While its conciseness lends it well to usage in informatics, its steep learning curve has resulted in limited utility.
What is the LAHSHAL system for cleft lip?
A further modification to the LAHSHAL system has been described, which allows designation of a skin band (sometimes referred to as Simonart band) that is present in a complete cleft lip, using a plus sign (+) in the L column if a skin band is present. The LAHSHAL system can describe over 12,000 combinations (of anatomy and severity) for CL/P.
What is the Randall classification of the palate?
Another method of morphologic description of the palate is the Randall classification, which describes palatal length (Randall class I being the normal length and class IV being severely short).
