[8] [9] [10] The most common form is combined cleft lip and palate and it accounts for approximately 50% of cases, whereas isolated cleft lip concerns 20% of the patients. [11] People with cleft lip and palate malformation tend to be less social and report lower self-esteem, anxiety and depression related to their facial malformation.
The upper lip is formed earlier than the palate, from the first three lobes named a to c above. Formation of the palate is the last step in joining the five embryonic facial lobes, and involves the back portions of the lobes b and c. These back portions are called palatal shelves, which grow towards each other until they fuse in the middle. [30]
The term free describes how the graft is completely removed from the donor site rather than remaining attached via a pedicle. The term autogenous, from the Greek root auto-("self"), describes how the individual who receives the graft is the same individual who provides the donor tissue. [3] The connective tissue is generally taken from the hard ...
In cleft palate patients bone grafting during the mixed dentition has been widely accepted since the mid-1960s. The goals of surgery are to stabilize the maxilla, facilitate the healthy eruption of teeth that are adjacent the cleft, improving the esthetics of the base of the nose, create a bone base for dental implants, and to close any oro-nasal fistulas.
Alveolar bone grafting in the mixed dentition is an essential part of the reconstructive journey for cleft lip and cleft palate patients. The reconstruction of the alveolar cleft can provide both aesthetic and practical advantages to the patient. [ 24 ]
The presence of buccal exostosis can be diagnosed by both clinical examination and radiological interpretation of the oral cavity. Clinically, buccal exostoses appear as single, broad-based masses, usually situated bilaterally in the premolar and molar region on the facial surface of the maxillary alveolar bone. [11]
Note: Additional shades of passive articulation are sometimes specified using pre-or post-, for example prepalatal (near the border between the postalveolar region and the hard palate; prevelar (at the back of the hard palate, also post-palatal or even medio-palatal for the middle of the hard palate); or postvelar (near the border of the soft ...
When discussing the anatomy of the face, it is often divided into thirds. The lower third extends from the chin to approximately the level of the upper teeth. The middle third continues from the teeth to just below the brow line. Finally, the upper third stretches from the brow to the hairline. [3] The facial skeleton
