What is Maxillomandibular Advancement for Sleep Apnea?
Maxillomandibular advancement (MMA) treats obstructive sleep apnea by skeletally enlarging the upper airway. By advancing both the maxilla and mandible 8-12 mm, the procedure increases pharyngeal cross-sectional area at all levels (retropalatal, retroglossal, hypopharyngeal), reduces airway collapsibility, and tensions the suprahyoid muscles to maintain patency during sleep.
MMA is indicated for adults with moderate-to-severe OSA (apnea-hypopnea index AHI ≥ 15) who fail or cannot tolerate continuous positive airway pressure (CPAP), demonstrate skeletal contributors (mandibular hypoplasia, retrognathia, narrow maxilla), and remain symptomatic. Contraindications include morbid obesity (BMI > 40), severe medical comorbidity, and active substance abuse.
Multidisciplinary evaluation includes sleep medicine, otolaryngology, dental, and oral and maxillofacial surgery. Workup includes polysomnography, drug-induced sleep endoscopy (DISE), CBCT with airway analysis, lateral cephalometry, and dental impressions. Virtual surgical planning, custom titanium plates, and CAD/CAM splints optimize outcomes. Success rates of 85-95% (≥ 50% AHI reduction) are reported, with cure rates (AHI < 5) of 40-60%.

Risk Factors
When to See a Doctor?
If you experience any of the following symptoms, seek medical attention promptly:
- Loud snoring with witnessed apneas
- Excessive daytime sleepiness despite adequate sleep
- Diagnosed moderate-to-severe OSA (AHI ≥ 15)
- Failed or intolerant of CPAP
- Failed mandibular advancement device
- Hypertension difficult to control
- Atrial fibrillation
- Stroke or transient ischemic attack history
- Skeletal disproportion (mandibular retrognathia)
- Quality-of-life impairment from OSA symptoms
- Considering surgical alternatives to CPAP
- Drug-induced sleep endoscopy showing multilevel obstruction

Anaemia
Dahiliye (İç Hastalıkları)
Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.
Iron Deficiency Anaemia
Dahiliye (İç Hastalıkları)
Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.
Vitamin B12 Deficiency
Dahiliye (İç Hastalıkları)
Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.
Hypertension (High Blood Pressure) Management
Dahiliye (İç Hastalıkları)
Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.
Chronic Kidney Disease
Dahiliye (İç Hastalıkları)
Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.
Hepatitis B (HBV)
Dahiliye (İç Hastalıkları)
Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.
Hepatitis C (HCV)
Dahiliye (İç Hastalıkları)
Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.
Fatty Liver Disease
Dahiliye (İç Hastalıkları)
Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
