MAXILLOMANDIBULAR ADVANCEMENT Meaning and
Definition
-
Maxillomandibular advancement (MMA) is a medical procedure performed to treat obstructive sleep apnea (OSA), a sleep disorder characterized by recurrent episodes of partial or complete blockage of the upper airway during sleep, leading to disrupted breathing and decreased oxygen levels in the body.
MMA involves surgically repositioning both the upper and lower jawbones forward, known as the maxilla and mandible, respectively. By advancing these facial structures, the size of the airway is increased, thus reducing the likelihood of airway obstruction during sleep. This procedure aims to promote uninterrupted breathing and improve oxygenation in individuals with severe OSA.
The surgery is usually performed under general anesthesia by an oral and maxillofacial surgeon, often in collaboration with an otolaryngologist or sleep medicine specialist. Prior to the surgery, a comprehensive evaluation of the patient's airway anatomy and sleep study results is conducted to determine the appropriateness of MMA.
Post-surgery, patients may experience facial swelling, soreness, and difficulty in jaw movement, which typically resolves within a few weeks. It is important for patients to adhere to a soft diet during the initial recovery period. Long-term success rates of MMA have shown significant improvements in sleep apnea symptoms and overall quality of life for many patients.
Maxillomandibular advancement is considered an effective treatment option for individuals with severe obstructive sleep apnea who have not responded adequately to other non-surgical treatments like continuous positive airway pressure (CPAP) therapy or oral appliances. It is crucial for patients to consult with their healthcare professionals to determine if they are suitable candidates for this surgical procedure.
Etymology of MAXILLOMANDIBULAR ADVANCEMENT
The term "maxillomandibular advancement" is composed of three components: "maxillo-", "mandibular", and "advancement".
1. "Maxillo-" is derived from the Latin word "maxilla", meaning "jawbone" or "upper jaw".
2. "Mandibular" is derived from the Latin word "mandibula", meaning "lower jaw".
3. "Advancement" is derived from the Old French word "avancement", which comes from the Latin word "advanciare", meaning "to go forward".
So, the etymology of "maxillomandibular advancement" combines elements referring to the upper and lower jaws along with the concept of moving forward or ahead.
