Combined orthodontic and surgical treatment for a patient with Hallermann-Streiff-Francois syndrome, severe obstructive sleep apnea, and history of antiresorptive medication.

Micrognathia and retrognathia, as observed in patients with the Hallermann-Streiff-Francois syndrome, might result in obstructive sleep apnea syndrome. When it becomes severe (apnea-hypopnea index [AHI], ≥30), noninvasive treatment options might be insufficient. An orthognathic treatment with mandibular advancement will increase the upper airway volume, which results in a decrease of apneas. A 53-year-old woman with Hallermann-Streiff-Francois syndrome and a history of antiresorptive medication suffered from severe obstructive sleep apnea (AHI, 77.7). She was treated with a combined orthodontic and surgical approach. The AHI decreased to 1, and the patient felt fitter after treatment. No medication-induced osteonecrosis nor inhibition of tooth movement was seen. A combined orthodontic and surgical treatment of a patient with severe obstructive sleep apnea was a good treatment choice. With a history of antiresorptive medication, the risks related to these medications have to be weighed up against the consequences of not treating obstructive sleep apnea syndrome. With a drug holiday, successful surgical treatment can be achieved.
