Objective: To discuss the surgical methods and clinical effect of endoscopic transoropharyngeal approach to deal with the lesions of the ventral region of the craniocervical junction.
Methods: From August 2002 to November 2006, endoscopic transoropharyngeal approach was taken to deal with the lesions of the ventral region of the craniocervical junction, including 6 patients with chordoma, 5 patients with craniovertebral malformation, 3 patients with skull-base invagination combined with Chiari malformation, 2 patients with odontoid fracture . 0 degrees endoscope was used to deal with the lesions of middle and lower clivus, 30 degrees endoscope was used to deal with the lesions of craniovertebral malformation.
Results: Follow-up ranged from 2 to 48 months. Three patients with chordoma recurred. All patients with craniovertebral malformation recovered.
Conclusions: Endoscopic transoropharyngeal approach is a new method to deal with the lesions of the ventral region of the craniocervical junction, and it has many advantages, such as direct approach, good exploration, micro-invasive, wide operation space, and good results.

Protraction of a mandibular second molar to substitute the adjacent missing first molar is challenging in clinical practice. In this case report, we demonstrated a 21-year-old patient with an untreatable periapical lesion of the mandibular right first molar. The adjacent mandibular second molar had normal root length and the third molar was mesially-impacted.

Pediatric spinal tumors include a variety of developmental lesions and uncommon neoplasms that differ significantly from those seen in adults. These conditions are underreported in the sub-Saharan medical literature. We present the case of a 10-year-old girl brought by her family to the University Teaching Hospital of Kinshasa in the Democratic Republic of Congo with progressive lower limb functional impairment.

Background/objectives: Intracranial arachnoid cysts (ACs) may be congenital, primary, or secondary due to trauma. These cysts are benign, contain cerebrospinal fluid (CSF), and are classified based on location, size, and their clinical symptomatology. They are uncommon lesions in children, rarely leading to severe mass-effect neurological symptomatology.

Pediatric middle ear cholesteatoma is an aggressive keratotic lesion caused by abnormal proliferation of keratinised squamous epithelium in the temporal bone, with the characteristics of high postoperative recurrence rate, poor hearing effect and poor quality of life. Endoscopic surgery is able to deal with the majority of pediatric middle ear cholesteatoma cases with the features of minimal trauma and wide surgical field. However, endoscopic surgical treatment still has problems in standardization.
