Summary
Temporal periosteum is consistently found against the skull bone, not between fascial layers. This anatomical finding supports a subperiosteal subtemporal surgical approach for craniostenosis.
Area of Science:
- Anatomy
- Surgical Anatomy
- Craniofacial Surgery
Background:
- The precise anatomical location of the temporal periosteum is debated in surgical literature.
- Some sources suggest it lies between deep and superficial temporal fascia, while others propose juxta-osseous localization.
Purpose of the Study:
- To clarify the anatomical position of the temporal periosteum.
- To evaluate the feasibility of a subperiosteal subtemporal approach in craniofacial surgery, particularly for craniostenosis.
Main Methods:
- Dissection of ten premature still-born neonates and two adult cadavers.
- Anatomical and histological (Hematoxylin-Eosin-Saffron staining) examination of the temporal region.
Main Results:
- The temporal periosteum was consistently observed adhered to the outer table of the calvarium in all specimens.
- Histological analysis confirmed the periosteum's direct contact with the bone.
Conclusions:
- The temporal periosteum is anatomically situated directly against the cranial bone.
- The temporalis muscle's insertion into the calvarium contributes to the periosteum's thinning in adults.
- A subperiosteal subtemporal approach is anatomically feasible and proposed for craniostenosis surgery.
