Combined Airway Surgery to Optimise Results
Genioglossus advancement and hyoid suspension are targeted surgical techniques used to improve airway stability in obstructive sleep apnoea (OSA).
These procedures are commonly used in conjunction with maxillomandibular advancement (MMA) to further optimise airway dimensions and reduce residual obstruction.
How These Procedures Contribute
Genioglossus Advancement
The genioglossus muscle forms the main support of the tongue base.
- It attaches to the inner surface of the chin
- Reduced tone during sleep contributes to posterior collapse
Genioglossus advancement:
- Moves the muscle attachment forward
- Increases baseline tension within the tongue
- Reduces the tendency for posterior airway collapse
Hyoid Suspension
The hyoid bone supports the lower airway and surrounding soft tissues.
Hyoid suspension:
- Repositions and stabilises the hyoid
- Improves support at the level of the hypopharynx
- Reduces airway narrowing in the lower pharynx
The Procedure
When performed alongside MMA:
- Genioglossus advancement is carried out via a controlled chin osteotomy to advance the muscle attachment
- Hyoid suspension uses sutures to reposition the hyoid bone to improve support of the lower airway
These procedures are integrated into the overall surgical plan and performed under the same general anaesthetic.
Recovery
Recovery follows a similar course to MMA, with:
- Swelling and discomfort in the early weeks
- A modified diet during initial healing
- Gradual return to normal function
When combined, there is no separate recovery pathway, but rather a unified postoperative course.
Outcomes
When used appropriately alongside MMA, these procedures can:
- Further reduce airway collapse at the tongue base
- Improve overall treatment efficacy
- Reduce the likelihood of residual obstruction
Their benefit lies in refinement and optimisation, rather than primary correction.
Consultation
A detailed consultation allows for assessment of your airway, review of previous treatments, and discussion of whether a combined surgical approach is appropriate.
