Abstract:
Hearing rehabilitation in children with craniofacial malformations is challenging not only because of reduced bone thickness but also due to complex anatomical and aesthetic considerations related to reconstruction. In such cases, conventional mastoid or retrosigmoid implantation of active transcutaneous bone conduction devices may not be feasible. We present our experience with two clinical cases, in which the optimal surgical site for placing a transcutaneous bone conduction device was over the middle fossa dura, selected after careful radiological assessment of skull thickness and venous anatomy. This technique proved to be a safe and effective alternative in children with limited bone thickness and/or craniofacial malformations, offering satisfactory hearing results and favorable cosmetic outcomes. The middle fossa dura placement may represent a valuable option for expanding indications of active transcutaneous bone conduction implants (t-BCIs) in complex pediatric cases.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
