Transoral approach to the cervico-medullary junction is a
well-established procedure. However oropharyngeal
complications in the form of soft tissue morbidity postoperatively
do occur. We report a case of a teenage boy with
traumatic quadriparesis secondary to compression of the
cervico-medullary junction by an os odontoideum.
Decompression was done via transoral approach through a
tubular retractor system, hence obviating the need for the
splitting or separate retraction of the soft palate and
minimised the damage and violation of surrounding soft
tissues. His neurological status improved and he was able to
ambulate with support on fourth post-operative day with no
soft tissue morbidity in the oral cavity. To our knowledge this
is the first case reported using this technique. We conclude
that adoption of this method would improve the traditional
transoral approach and reduce the oropharyngeal
complications.

The management of post-radiation wound breakdown
over the posterior cervico thoracic region can be a
challenging task for a surgeon. The aim of the treatment
is to produce a well vascularized and a low tensile flap
which will close a large defect. We describe the use of the
lower trapezius flap to reconstruct the wound breakdown
and to obtain stable tissue coverage in a patient with postradiation
necrosis. This flap minimizes the disruption
of the scapula-thoracic function while preserving the
range of movement over the shoulder. From the literature
review, it was noted that the dorsal scapular artery (DSA)
and transverse cervical artery (TCA) aid in the blood
supply to the trapezius muscle and prevent local necrosis
during rotation of the flap. The trapezius flap is widely
accepted because of the minor donor site morbidity, large
arc of rotation and adequate blood supply.

Osteoradionecrosis, a rare complication of radiation therapy,
is a slow progression disease which affects the surrounding
structures of spinal components. It essentially weakens the
soft tissue and bony configuration and can cause nerve
impingement or cord compression. We describe a patient
who underwent radiotherapy for thyroid cancer and
presented with cervical kyphosis with anterolisthesis of
C3/C4 and C4/C5 some 32 years later. We explore the role of
anterior and posterior fusion, as well as hyperbaric oxygen
therapy in promoting healing.

Firearm injuries to the spine commonly present with acute
neurology caused by direct penetration or indirectly from
concussive effects of bullet impact on the vertebral column. We report a case of delayed neurologic presentation of retained intra-spinal bullet in a 42 year-old African who had chronic low back pain and sciatica with a past history of gunshot injury to the spine and radiograph revealed a bullet at the L4-5 disc level. Intra-operative exploration showed a fibrous mass around the bullet compressing on the L4 existing nerve root and L5 traversing nerve root. Removal of the retained bullet resulted in a good clinical outcome with
complete resolution of symptoms.
5.Severe Cervicothoracic Kyphoscoliosis in Neurofibromatosis - A Failure Of Posterior-Only Instrumentation: A Case Report

Treatment of severe spinal deformities associated with neurofibromatosis has proven to be challenging. An 11-yearold girl, with neurofibromatosis and severe cervicothoracic kyphoscoliosis, was initially treated with posterior instrumentation and fusion. Implant failure developed within a year, requiring an anterior stabilisation and fusion with a non-vascularised fibular strut graft for better stability and increased likelihood of achieving union. The posterior instrumentation was removed due to its prominence and wound breakdown. Following the removal of the posterior implant, the fibular graft fractured. The patient was maintained on a cervical collar until union was achieved. Posterior spinal fusion alone in severe spinal deformities in neurofibromatosis has a high risk of failure. A combined anterior and posterior fusion may increase the chance of success, with better stability and union rate.

Introduction: To investigate the use of a tubular retractor to
provide access to the craniovertebral junction (CVJ) sparing
the soft palate with the aim of reducing complications
associated with traditional transoral approach but yet
allowing adequate decompression of the CVJ.
Materials and methods: Twelve consecutive patients with
severe myelopathy (JOA-score less than 11) from ventral
CVJ compression were operated between 2014-2020 using a
tubular retractor assisted transoral decompression.
Results: All patients improved neurologically statistically
(p=0.02). There were no posterior pharynx wound infections
or rhinolalia. There was one case with incomplete removal of
the lateral wall of odontoid and one incidental durotomy.
Conclusions: A Tubular retractor provides adequate access
for decompression of the ventral compression of CVJ. As the
tubular retractor pushed away the uvula, soft palate and
pillars of the tonsils as it docked on the posterior pharyngeal
wall, the traditional complications associated with traditional
transoral procedures is completely avoided.
