Summary
Extended transoral approaches improve ventral craniovertebral junction lesion exposure. Surgical decisions for these complex procedures should be guided by preoperative evaluation to balance maximal exposure with minimized complications.
Area of Science:
- Neurosurgery
- Surgical Anatomy
- Craniovertebral Junction Surgery
Background:
- The transoral approach offers direct access to ventral craniovertebral junction extradural lesions.
- Extended transoral modifications are necessary for lesions exceeding standard exposure limits.
- These modifications increase surgical complexity and complication risks.
Purpose of the Study:
- Review literature on extended transoral approaches.
- Analyze modifications for technical aspects, exposure gain, and complications.
Main Methods:
- Analysis of classic approaches and morphometric studies.
- Tabulation of exposure limits and complication risks for various modifications.
Main Results:
- Transmaxillary approaches extend exposure to the sphenoid sinus and upper clivus.
- Mandibulotomy/mandibuloglossotomy expand inferior exposure to C4-C5.
- Palatotomy offers rostral exposure without facial incision but risks velopharyngeal insufficiency.
Conclusions:
- Preoperative evaluation of anatomy, pathology, and imaging is crucial.
- Informed decisions maximize surgical exposure.
- Minimizing complications is a key consideration in approach selection.
