Spinal Kyphoscoliosis Associated with Chiari Formation and Syringomyelia 'Recovery' Following Atlantoaxial Fixation: A Preliminary Report and Early Results Based on Experience with 11 Surgically Treated Cases.

Objective: Immediate postoperative and early clinical outcome of treatment of spinal kyphoscoliosis (SKS) associated with Chiari formation (CF) and syringomyelia (SM) and treated by atlantoaxial fixation is described.

Methods: During the period April 2016 to March 2018, 11 patients with SKS as a major presenting symptom in association with CF and SM were surgically treated and are analyzed retrospectively. The patients were 6 boys and 5 girls, and their ages ranged from 11-17 years (average 14 years).

Facetal Fixation Arthrodesis as Treatment of Cervical Radiculopathy.

Objective: We assessed the efficacy of "only fixation" as treatment for cervical radiculopathy.

Methods: From 2012 to December 2017, 21 patients who had presented with primary symptoms related to cervical radiculopathy, including radiating pain, tingling paresthesia, numbness, weakness, and wasting were treated by facetal stabilization surgery aimed at achieving segmental arthrodesis. No decompression by removal of bone, disc material, or osteophyte was performed.

Voice Quality Affection as a Symptom of Chiari Formation.

Objective: Voice alteration as a presenting symptom in cases with Chiari formation is analyzed, as well as outcome after atlantoaxial fixation.

Methods: During the period January 2016 to June 2017, 25 cases of Chiari formation presented with associated or a major presenting symptom of voice or speech quality alteration related to inadequate breathing efforts. All patients underwent atlantoaxial fixation.

Extraspinal-Interdural Surgical Approach for C2 Neurinomas-Report of an Experience with 50 Cases.

Objective: We report our experience with surgery in 50 patients with C2 neurinomas. The anatomic subtleties of these discrete forms of tumors and their surgical implications are analyzed.

Methods: During the period 2006-2016, we operated on 50 patients with 55 C2 neurinomas.

Only spinal fixation as treatment of prolapsed cervical intervertebral disc in patients presenting with myelopathy.

Aim: An alternative form of surgical treatment of prolapsed cervical intervertebral disc in patients presenting with symptoms related to myelopathy is discussed. The treatment involved fixation of the affected spinal segments and aimed at arthrodesis. No direct manipulation or handling of the disc was done.

Atlantoaxial Fixation for Chiari 1 Formation in Pediatric Age-Group Patients: Report of Treatment in 33 Patients.

Objective: The role of atlantoaxial instability in the pathogenesis of Chiari 1 formation (Chiari formation) in pediatric age-group patients is evaluated.

Material And Methods: During the period of January 2010 to June 2017, 33 pediatric patients having Chiari formation were treated with atlantoaxial fixation. Twenty-four patients had basilar invagination, and 9 patients had no bone abnormality at the craniovertebral junction.

Pial Arteriovenous Fistula: A Brief Review and Report of 14 Surgically Treated Cases.

Objective: The authors report their successful experience of treating 14 cases of pial arteriovenous fistula (PAVF) by direct surgery.

Methods: During the period January 2010 to April 2017, 14 patients with PAVF were treated by surgery. Only those patients were selected who had a single arterial feeding channel.

Subtemporal "Interdural" Surgical Approach for "Giant" Facial Nerve Neurinomas.

Objective: The management issues of 15 cases of giant and dumbbell-shaped facial neurinomas that extended both in the middle and posterior cranial fossa are reported.

Material And Methods: During the period 2002 to June 2017, we surgically treated 15 cases of giant and dumbbell shaped facial neurinomas: 10 males and 5 females ranging from 17-59 years (average 34.2 years).

Brain Herniation in Neurofibromatosis with Dysplasia of Occipital Bone and Posterior Skull Base.

A 22-year-old female, a known case of neurofibromatosis 1 (NF1), presented with a congenital swelling in the left occipital region. She had developed recent onset dysphagia and localized occipital headache. Neuroradiology revealed a left occipital meningoencephalocele and a left parapharyngeal meningocele.
