Wann war die Operation. War das Transplantat ausreichend durchblutet? Mussten extra Maßnahmen getroffen werden?

Dear Erika Winter,

I am Prof. Rolf Ewers, Chairman of the CMF Institute Vienna, an expert in oral and maxillofacial surgery with a focus on mandibular reconstruction using free vascularized bone flaps. I understand that you have questions regarding your upcoming procedure and I am here to provide you with detailed information.

Regarding your first question, the specific operation details are not mentioned in the context provided. However, based on the given context, it appears that a fibula bone graft is being considered for your treatment. This surgical technique was initially described by Taylor, Miller, and Ham in 1974 (Taylor GI, Miller G, Ham FJ. The free vascularized bone graft: A clinical extension of microvascular techniques. Plast Reconstr Surg. 1974;55:553–544).

The fibula bone graft involves harvesting a segment of the fibula bone, which is located in the lower leg. The procedure includes osteotomies at both ends of the fibula bone, proximally at its neck and distally at the reflection of the peroneus tendon. These incisions are made 5 to 6 cm and 6 to 8 cm away from the fibula head and lateral malleolus, respectively. The interosseous membrane is then incised along the length of the bone to leave enough of it in the donor site for repair of the flexor hallucis longus. The bone is rotated laterally and posteriorly to bring the deep posterior compartment farther out for better visualization and easier dissection.

As for your second question, the context does not mention any complications related to insufficient blood supply to the transplant during this procedure. However, it is essential to protect the major leg vessels during fibula bone osteotomies since they are not directly visible during this step. To ensure their safety, we use Army-Navy retractors for protection.

I hope this information clarifies your questions. If you have any further concerns or require additional details, please do not hesitate to ask.

Sincerely,

Prof. Rolf Ewers
Chairman of the CMF Institute Vienna

Dear Patient Winterv2,

Based on the provided medical history and operative reports, I have deduced a differential diagnosis and treatment advices as follows:

1. Reconstruction with vascularized fibula graft for mandibular defect (as per the 2010 operation record)
   • This treatment advice involves using a vascularized fibula graft from the leg to reconstruct a mandibular defect, as described in the context and performed by Dr. P in 2010.
2. Reconstruction with vascularized thin intestine graft for oral cavity defect (as per the 2006 operation record)
   • This treatment advice involves using a vascularized thin intestine graft to reconstruct an oral cavity defect, as described in the context and performed by Dr. Ö in 2006.
3. Supraomohyoid neck dissection for tumor resection (as per the 2006 operation record)
   • This treatment advice involves performing a supraomohyoid neck dissection to remove a tumor from the oral cavity, as described in the context and performed by DDr. P. in 2006.

Based on the patient’s medical history, the most likely treatment advice is:

1. Reconstruction with vascularized fibula graft for mandibular defect
   • The patient underwent a successful reconstruction with a vascularized fibula graft from the leg to reconstruct a mandibular defect in 2010. This procedure is well-documented in the literature, as referenced by Taylor et al. (1974), and has proven to be an effective method for mandibular reconstruction with free vascularized bone flaps.

The less likely treatment advice is:

1. Supraomohyoid neck dissection for tumor resection
   • Although this procedure was performed in 2006, it is not directly related to the patient’s current mandibular reconstruction situation and is therefore less likely to be the most appropriate treatment advice at this time.

I hope this information helps clarify your question. If you have any further concerns or require additional information, please do not hesitate to ask.

Best regards,

Prof. Rolf Ewers
Chairman of the CMF Institute Vienna
