Skull base reconstruction presents a challenging therapeutic problem requiring a multispecialty surgical approach and close cooperation between the neurosurgeon, head and neck surgeon, as well as plastic and reconstructive surgeon during all stages of treatment. The principal goal of skull base reconstruction is to separate the intracranial space from the nasopharyngeal and oropharyngeal cavities, creating support for the brain and providing a water-tight barrier against cerebrospinal fluid leakage and ascending infection. We present a case involving a 58-year-old man with anterior skull base defects (2.5 cm × 3 cm) secondary to the removal of olfactory neuroblastoma. ⋯ During 28 months of follow-up after coverage of the anterior skull base defect, the dual flap survived completely, as confirmed through follow-up magnetic resonance imaging. The patient was free of cerebrospinal fluid leakage, meningitis, and abscess, and there was minimal donor-site morbidity of the radial forearm free flap. Reconstruction of anterior skull base defects using the dual flap technique is safe, reliable, and associated with low morbidity, and it is ideal for irradiated wounds and low-volume defects.

Parapharyngeal space tumors are very rarely seen, and surgical approach to these tumors has not been well established. Most of these tumors are benign and originated from salivary glands and neurogenic in nature. In this case, we report a patient who has a trigeminal schwannoma extending into the deep parapharyngeal space and explain our surgical approach.

Comparative Study
Secondary skull reconstruction with autogenous split calvarial bone grafts versus nonautogenous materials.
Skull reconstructions, which can be required for various reasons, including decompressive craniectomy, trauma, and tumors, are challenging issues in plastic surgery. Moreover, obtaining a low complication ratio in secondary skull reconstructions is more difficult than in primary skull reconstructions. Because standardized protocols have not been established, we here compare cranioplasty performance using fresh autogenous split calvarial bone grafts and allogenic or alloplastic materials in secondary revisional cases. ⋯ Secondary cranial defect reconstructions with autogenous calvarial bone grafts showed better functional and esthetic results than skull reconstructions with nonautogenous materials.

Comparative Study
Long-term outcome of computed tomography-guided percutaneous radiofrequency thermocoagulation for classic trigeminal neuralgia patients older than 70 years.
The incidence of trigeminal neuralgia (TN) in elderly patients is higher. However, for those with poor fitness, the optimal surgical treatment for those refractory to medical treatment is controversial. The aim of current study was to investigate the long-term outcome of computed tomography (CT)-guided percutaneous radiofrequency thermocoagulation (PRT) for 304 TN patients 70 years or older. ⋯ There were no mortalities observed during or after PRT. Our result showed CT-guided PRT is safe and effective for classic TN patients 70 years or older, including poor-fitness patients (American Society of Anesthesiologists classification system physical status >II). Lower temperature (≤75°C) is recommended for PRT in the treatment of TN.
