Abstract
The unsatisfactory results of UPPP and its modification in the
treatment of snoring and sleep apnea were disappointing. The
recurrence of symptoms increased with the longer follow up. The bad
impressions of the results of these operations were due to missing of
other levels of collapse. The commonest site of collapse after the
retropalatal area is the base of the tongue, which produce narrowing of
the retrolingual area during sleep
Hyoid suspension and laser midline glossectomy were
designed to prevent its collapse. The study concerned to discuss these
two types of surgeries. Hyoid suspension suspension as example of
stabilizing operation of the base of the tongue to prevent its collapse
during sleep. Midline laser glossectomy was another example for
reduction surgery to reduce the size of the obstructive part of the
tongue.
The results of both surgeries were significant in reducing the
OSA.
The improvement in (AHI) more than 50 % is considered as a
responder to surgery. The responder patients in hyoid suspension
technique were 66.67% and non-responder patients were 33.33% but
in midline laser glossectomy responder patients were 53.3% and nonresponder
patients were 46.7%
In hyoid suspension operation the reduction of the mean of
(AHI) in responders was 77.2% and in non-responders was 36.2% but
in midline laser glossectomy the reduction of AHI in responders was
73.9% and in non-responders was 40.8%.
Summary

In this study: Hyoid suspension procedure appeared to be
more efficient than laser midline glossectomy in controlling OSA.
Laser midline glossectomy had significant peri-operative morbidity,
immediately peri-operatively significant pain, and dysphagia occurred.
Various methods were used to minimize morbidity (pain and
swallowing difficulties) with corticosteroids and non steroidal antiinflammatory
medications.
Hyoid suspension is expensive if done by Repose screw
system (Devices included is about 8000 L.E.).
However a simple, economic modification of hyoid suspension
was demonstrated in this study.
The advantages of hyoid suspension are:
1-Safe and effective:
Hyoid suspension is safe and effective in reducing obstructive
sleep apnea severity.
2- Minimally invasive:
Through a single, small incision with the operation typically
completed in less than an hour.
3-Improved recovery:
While the recovery experience is different for every patient,
since hyoid suspension does not directly affect the soft tissues of the
tongue and tongue base, recovery from the procedure tends to be less
painful than other obstructive sleep apnea treatments that directly
target the soft tissue of the airway.

4-100% reversible:
In the rare case of persistent side effects or other post-treatment
complications, the hyoid suspension and all implantation materials can
be easily removed.
5-Does not limit treatment options:
Hyoid suspension may be used with other sleep apnea medical
therapies or surgery techniques. It does not limit future treatment
options if you have progressive disease.
