BACKGROUND: Several authors highlighted the limitations of the Keros classification system in predicting intracranial entry risk. Recently, our group proposed a new classification system based on the angle formed between the lateral lamella of the cribriform plate (LLCP) and the continuation of an horizontal plane passing through the cribriform plate (Gera classification). The aim of this study was to analyze whether the risk of iatrogenic cerebrospinal fluid leak (CSF-L) was better predicted by Keros or Gera classification...

Total laryngectomy remains essential treatment for locally advanced laryngeal carcinoma, related to better survival rates. However, it involves changes for the patient, such as the inability to communicate verbally, breathing or aesthetic changes, which affect their quality of life and require comprehensive rehabilitation. This paper was written by the total laryngectomy rehabilitation workgroup of the National Head and Neck and Skull Base working committee of the Spanish Society of Otolaryngology and Head and Neck Surgery...

BACKGROUND: Mastoid emissary vein is especially important from the neurosurgical point of view, because it is located in variable number in the area of the occipitomastoid suture and it can become a source of significant bleeding in surgical approaches through the mastoid process, especially in retrosigmoid craniotomy, which is used for approaches to pathologies localized in the cerebellopontine angle. Ideal imaging method for diagnosis of these neglected structures when planning a surgical approach is high-resolution computed tomography...

Skull base metastasis from differentiated thyroid carcinoma (DTC), including papillary and follicular thyroid carcinoma, is a rare manifestation and easily misdiagnosed. In this study, we reported three cases whose initial clinical presentation was skull base metastasis complaints with the presence of silent primary sites. Based on the thyroid ultrasound and histopathology (identifying skull base and primary thyroid tumor), the final diagnoses of DTC metastasis to skull base were confirmed. Two patients underwent removal of metastasizing tumors in the skull base and primary thyroid cancer, and have respectively survived 58 months and 4 months since then...

Skull base meningioma leads to functional disturbances, which can significantly alter the quality of life. The optimal management of these lesions, whose goals are neurological preservation and tumour local control, is not yet clearly established. It is widely recognized that the goal of a radical excision should be abandoned despite the advances in the field of microsurgery of skull base lesions. Although less morbid, partial tumour excision would be associated with increased risk of local tumour recurrence...

REVIEW
Hua Gao, Chunhui Liu, Yazhuo Zhang
The endoscope has traditionally been used in neurosurgery to access a lesion within a natural body cavity. The challenge has been to access and resect deep-seated intraparenchymal lesions using a minimally invasive endoscopic technique. Endoscopic endonasal trans-sphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. Surgical procedures of the skull base include exposure, resection, and base reconstruction. These approaches start at the sphenoid sinus, which provides a reference point to important vascular and neural structures...

We analyzed the outcomes of patients with large cerebellopontine angle (CPA) tumors treated by a skull-base team in which two surgeons (one neurosurgeon and one otological surgeon) were in the beginning of their careers (<40 years old). Data of patients operated on between April 2012 and March 2016 were reviewed. All factors related to surgical training were considered. Thirty-one patients had vestibular schwannomas, while 26 had meningiomas. Mean tumor diameter was 30.6 mm (range, 23-49 mm) for schwannomas and 35 mm (range, 22-51 mm) for meningiomas...
