[Secondary surgeries for facial osteotomies: 10 cases]
14, rue Claude-Bador, 69500 Bron, France.
Summary
Reoperations in orthognathic surgery are common, especially in patients with sleep apnea, lingual dysfunction, or oral ventilation issues. These factors increase the risk for patients undergoing corrective jaw surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Orthodontics
Background:
- Orthognathic surgery is a predictable treatment for dento-maxillo-facial deformities.
- Increasing indications and patient pursuit of perfection lead to more complex cases and reoperations.
- The goals of orthognathic surgery are functional, occlusal, and aesthetic.
Purpose of the Study:
- To analyze factors influencing reoperations in orthognathic surgery.
- To identify patient-specific risk factors for secondary osteotomies.
- To evaluate outcomes of revision orthognathic procedures.
Main Methods:
- Retrospective study of 10 patients undergoing revision orthognathic surgery.
- Analysis included initial indications, surgical types, orofacial functions, reoperation timing, and techniques.
- Evaluation of pre-existing conditions such as obstructive sleep apnea (OSAS), lingual dysfunction, and oral ventilation.
Main Results:
- Patients requiring reoperation often presented with at least one negative factor: OSAS, lingual dysfunction, or oral ventilation.
- These factors were identified as potential predictors for secondary surgeries.
- The study noted a lack of extensive literature on the frequency of revision orthognathic surgeries.
Conclusions:
- Specific patient factors like OSAS, lingual dysfunction, and oral ventilation are associated with increased reoperation rates in orthognathic surgery.
- Identifying these risk factors is crucial for managing patient expectations and surgical planning.
- Further research is needed to establish the precise frequency and outcomes of revision orthognathic procedures.

Secondary Active Transport
137.3K
One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Secondary Healthcare System

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident. Whatever...

Primary and Secondary Growth in Roots and Shoots
60.2K
Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Facial Feedback Hypothesis
612
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Muscles for Facial Expressions
4.7K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
