[Modified hyoid suspension for therapy of sleep related breathing disorders. operative technique and complications].
BACKGROUND
: Concerning the therapy of obstructive sleep apnea (OSA) the discrimination between either retropalatal or retrolingual site of obstruction seems to be an oversimplification. Thus modern surgical concepts address both anatomical areas. Minimal invasive surgical techniques treating the soft palate have recently been developed while there is still an ongoing development concerning the base of tongue.


METHODS
A less invasive modification of the hyoid suspension to the thyroid cartilage, originally described by Riley, is presented as treatment modality for sleep related breathing disorders. Between October 2000 and March 2001, 14 patients underwent modified hyoid suspension within a multi-level surgery concept. The operative technique manages with only one wire-suture and does not include myotomies and intersection of the ligamenta stylohyoidea.


RESULTS
All together 10 male and 4 female subjects with a mean age of 50.9 years were included in the analysis. Preoperatively the mean apnea hypopnea index (AHI) was 18.4. The procedure was well tolerated. Neither increased postoperative pain nor increased requirement of analgetics was observed. Substantial side-effects were one case of seroma and 9 cases of transitory dysphagia. The retrolingual airway space increased significantly after surgery.


CONCLUSIONS
These preliminary results are promising. The presented modified hyoid suspension is time-effective and shows less postoperative morbidity. Therefore it might become a suitable treatment modality within the multi-level surgery concept for sleep related breathing disorders.
