OBJECTIVES

To present a rare case of a 17-year-old girl with multiple odontogenic keratocysts, skeletal abnormalities, central nervous system and cutaneous anomalies.

METHODS

Design:Case Report

Setting:Tertiary Government Training Hospital

Patient: One

RESULTS

A 17-year-old Filipino girl presented with a one-year history of progressive left mandibular swelling. Orthopantomography revealed multiple cysts involving the mandible and maxillae. Histopathologic examination of incision biopsy specimens confirmed odontogenic keratocysts. Other physical examination findings included coarse face and multiple palmar and plantar pits. Radiologic investigations demonstrated calcification of the falx cerebri and tentorium cerebelli, bifid rib and cervicothoracic scoliosis. Based on clinical, radiological, and histopathological findings, a diagnosis of Gorlin-Goltz syndrome was established. The patient underwent enucleation and curettage of the cysts with peripheral ostectomy, and there was no recurrence on repeat orthopantomography at six months and two years post-operatively. However, on the fourth year, the patient claimed there was a mandibular cyst which was not verified as she was lost to follow-up.

CONCLUSION

This case highlights the importance of recognizing multiple odontogenic keratocysts as a potential manifestation of Gorlin-Goltz Syndrome. Early diagnosis enables appropriate management and long term surveillance to monitor for other manifestations of this syndrome that may occur later in life.

STUDY DESIGN: Observational cohort study. PURPOSE: To assess the surgical outcomes of posterior decompression and fusion for cervical myelopathy in patients with athetoid cerebral palsy. OVERVIEW OF LITERATURE: Patients with athetoid cerebral palsy demonstrate involuntary movements and develop severe cervical spondylosis with kyphosis. In these patients, surgery is often performed at an early age because of myelopathy. A few studies have reported about the long-term outcomes of surgical treatment; however, they contain insufficient information. METHODS: From 2003 to 2008, 13 patients with cervical myelopathy due to athetoid cerebral palsy underwent posterior fusion surgery and were included in this study. The Japanese Orthopaedic Association (JOA) score, neck disability index (NDI), C2–7 angle on radiography, and need for additional surgical treatment were examined at 1 and 5 years postoperatively. RESULTS: The mean C2–7 angle was −10.5°±21.1° preoperatively and was corrected to −2.9°±13.5° immediately postoperatively. This improvement was maintained for 5 years. The JOA score was 9.5±2.5 preoperatively and 12.2±1.7 at the 5-year follow-up. NDI was 17±6.9 preoperatively and 16±7.5 at the 5-year follow-up. Patient satisfaction with surgery on a 100-point scale was 62.2±22.5 at the 5-year follow-up. Three patients needed additional surgery for loosening of screws. These results demonstrate good surgical outcomes for posterior fusion at 5 years. CONCLUSIONS: Posterior decompression and fusion should be considered a viable option for cervical myelopathy in patients with athetoid cerebral palsy.

OBJECTIVE: The aim of this study was to compare the clinical and radiological outcomes associated with the use of hydroxyapatite (HA) spacer and allogeneic bone (AB) spacer in laminoplasty. METHODS: From January 2006 to July 2014, 79 patients with cervical spondylotic myelopathy or ossification of the posterior longitudinal ligament underwent cervical laminoplasty. The radiologic parameters were obtained from plain radiography and three-dimensional computed tomography. All images were taken before and after surgery. Cervical lordosis, spinal canal dimension, fusion between lamina and spacer, and resorption of spacer were checked. Clinical outcomes were assessed using visual analog scale and Japanese Orthopedic Association. RESULTS: Double-door laminoplasty was performed on 280 levels : 182 in the HA group and 98 in the AB group. The mean follow-up was 23.1 months (range : 4–69 months). Similar fusion rates were found in these groups (p=0.3). The resorption rate between lamina and spacer was lower in the HA group (p<0.001). During the immediate postoperative period, the canal dimension of both groups increased compared with the results in the preoperative period. However, the canal dimension of the AB group decreased over time compared with that of the HA group (p<0.001). CONCLUSION: Double-door laminoplasty improved the clinical outcomes of both groups. However, the spinal canal dimension in the AB group showed a greater degree of reduction than in the HA group at the final postoperative follow-up. Therefore, we suggest that surgeons consider the use of larger-sized AB spacers in double-door laminoplasties.

OBJECTIVE: The purpose of this study was to demonstrate the usefulness of digital subtraction cystography to identify communicating holes between a spinal extradural arachnoid cyst (SEAC) and the subarachnoid space prior to cyst removal and hole closure. MATERIALS AND METHODS: Six patients with SEAC were enrolled in this retrospective study. Digital subtraction cystography and subsequent CT myelography were performed for every patient. The presence and location of the communicating holes on cystography were documented. We evaluated the MRI characteristics of the cysts, including location, size, and associated spinal cord compression; furthermore, we reviewed cystographic images, CT myelograms, procedural reports, and medical records for analysis. If surgery was performed after cystography, intraoperative findings were compared with preoperative cystography. RESULTS: The location of the communicating hole between the arachnoid cyst and the subarachnoid space was identified by digital subtraction cystography in all cases (n = 6). Surgical resection of SEAC was performed in 4 patients, and intraoperative location of the communicating hole exactly corresponded to the preoperative identification. CONCLUSION: Fluoroscopic-guided cystography for SEAC accurately demonstrates the presence and location of dural defects. Preoperative digital subtraction cystography is useful for detection of a communicating hole between a cyst and the subarachnoid space.

OBJECTIVE: Anterior cervical discectomy and fusion (ACDF) is a choice of surgical procedure for cervical degenerative diseases associated with radiculopathy or myelopathy. However, the patients undergoing ACDF still have problems. The purpose of the present study is to evaluate the radiologic results of 3 different methods in single-level ACDF. METHODS: We conducted a retrospective collection of radiological data from January 2011 to December 2014. A total of 67 patients were included in this study. The patients were divided into 3 groups by operation procedure: using stand-alone cage (group cage, n=20); polyether-ether-ketone (PEEK)-titanium combined anchored cage (group AC, n=21); and anterior cervical cage-plate (group CP, n=26). Global cervical lordosis (C2-C7 Cobb angle), fused segment height, fusion rate, and cervical range of motion (ROM) were measured and analyzed at serial preoperative, postoperative, 6-month, and final 1-year follow-up. RESULTS: Successful bone fusion was achieved in all patients at the final follow-up examination; however, the loss of disc height over 3 mm at the surgical level was observed in 6 patients in group cage. Groups AC and CP yielded significantly better outcomes than group cage in fused segment height and cervical ROM(p=0.01 and p=0.02, respectively). Furthermore, group AC had similar radiologic outcomes to those of group CP. CONCLUSION: The PEEK-titanium combined anchored cage may be a good alternative procedure in terms of reducing complications induced by plate after ACDF.

OBJECTIVETo analyze the factors in the non-operative treatment of cervical spinal cord injury without fracture or dislocation.

METHODSThe clinical data of 122 patients with cervical spinal cord injury without fracture or dislocation from January 2009 to December 2012 treated by non-operative treatment were retrospectively reviewed. There were 84 males and 38 females, aged from 18 to 83 years with an average of (52.37 +/- 13.27) years. The clinical features, such as age, gender, cause of injury, time from injury to treatment, ASIA grade of spine cord injury, MRI type of spine cord injury, range of spine cord injury, effective cervical spinal canal ratio, Pfirrmann grade of intervertebral disc herniation, segment of intervertebral disc herniation, intervertebral disc ligament complex injury, treatment of high-dose methyiprednisolone, were observed. Single factor and multiple factor Logistic regression analysis were used in the clinical data in order to analyze the influencing factors of above items to prognosis.

RESULTSFor univariate analysis, the factors such as MRI type of spine cord injury, extent of spine cord injury, effective cervical spinal canal ratio, Pfirrmann grade of intervertebral disc herniation, segment of intervertebral disc herniation, ASIA grade of spine cord injury, associated with prognosis (P < 0.05). Multiple linear regression analysis showed that the main prognostic factors including MRI type of spine cord injury, range of spine cord injury, effective cervical spinal canal ratio, Pfirrmann grade of intervertebral disc herniation, ASIA grade of spine cord injury according to its effective intension (P < 0.05).

CONCLUSIONThe main prognostic factors on non-operative treatment of cervical spinal cord injury without fracture or dislocation were MRI type and extent of spine cord injury, meanwhile, correlate with effective cervical spinal canal ratio, Pfirrmann grade of intervertebral disc herniation, ASIA grade of spine cord injury. It is deliberative to choose no-operative treatment, for it only refers to the patients with the mild localized edema type or no signal change of spinal cord in MRII. Operative treatment shoud be recommended for other patients.

Cervical spondylotic myelopathy (CSM) is a common cause of spinal cord dysfunction clinical disease. Surgery is the main therapeutic tool for CSM. However, there are obvious differences in clinical functional recovery after operation. For the past few years, the influence factors of prognosis in cervical spondylosis myelopathic has been widely concerned. Age, nerve function, course of desease, imaging findings,surgical method and related factors became the investigative point for prognosis of cervical spondylotic myelopathy. Present viewpoint showed that the older patient, preoperative worse nerve function, longer the course of disease would result in worse outcomes. Imaging examination maybe can indicate the prognosis, but the correlation is unclear. Selection of surgical method and approach should be based on the principles of sufficient decompression, stabilize the alignment of the cervical spine, keeping backward extension of cervical spine, maintain effective decompression, preventing complications. Therefore, the treatment of cervical spondylotic myelopathy should be on the basis of pathogenic condition and imaging examination at early stage and a suitable usrgical procedure should be performed to obtain a better prognosis.

OBJECTIVETo explore the clinical effects of anterior corpectomy decompression and titanium mesh bone graft fusion combined with titanium plate fixation in treatting multilevel cervical spondylotic myelopathy.

METHODSThe clinical data of 48 patients with multilevel cervical spondylotic myelopathy underwent surgical operation were retrospectively analyzed from October 2010 to January 2013. There were 37 males and 11 females, aged from 37 to 76 years old with an average of 54.6 years. Thirty-five cases were two-segment lesion, 7 cases were three-segment lesion, 6 cases were four-segment lesion. All the patients were treated by anterior corpectomy decompression and titanium mesh bone graft fusion combined with titanium plate fixation. ROM, JOA, VAS and SF-36 scores were recorded before and after operation(including 3, 6, 12 months after operation and final follow-up). Fusion degree and spinal canal decompression condition were observed by radiographic data.

RESULTSAll patients were followed up from 14 to 48 months, with an average of 27.3 months. At 12 months after surgery, radiographic data showed that all patients obtained bony fusion, spinal canal decompression were sufficient. Preoperative vertebral canal sagittal diameter of the most serious segment were (5.13 +/- 1.32) mm, 12 months after surgery were (9.94 +/- 1.22) mm, there was statistically significance (t=2.463, P=0.014); the degree of vertebral canal decompression were (92.15 +/- 2.35)%. Postoperative ROM, JOA, VAS and SF-36 scores were obviously improved than that of preoperative (P<0.05); there was no statistically significance of ROM, JOA, VAS and SF-36 scores in each time after operation (P>0.05).

CONCLUSIONAnterior corpectomy decompression and titanium mesh bone graft fusion combined with titanium plate fixation can obtain higher fusion rate, complete thoroughly decompression, improvement of clinical symptoms and well safety in treating multilevel cervical spondylotic myelopathy.

OBJECTIVETo compare the clinical outcomes of anterior cervical decompression plus sublevel fusion and posterior cervical laminoplasty in treating multilevel cervical spondylotic myelopathy.

METHODSThe clinical data of 56 patients with multilevel cervical spondylotic myelopathy were retrospectively analyzed from July 2009 to June 2012. There were 32 males and 24 females, aged from 42 to 79 years old with an average of (56.9 +/- 12.8) years. All patients had the typical clinical features of cervical spondylotic myelopathy,radiological evidences, and courses of disease were from 2 months to 16 years with an average of (10.6 +/- 3.2)years. Of them,34 patients were treated with anterior cervical decompression plus sublevel fusion (anterior fusion group) and 22 patients with posterior cervical laminoplasty (posterior laminoplasty group). JOA score and radiological data were used to evaluate the clinical results:

RESULTSNo complications about nerve and blood vessel was found and the patients were followed up from 24 to 36 months with an average of 28.6 months. In anterior fusion group, the cervical anterior column height was significantly increased and the anterior cervical curvature angle was significantly decreased at 2 weeks after surgery (P < 0.05). In posterior laminoplasty group, there was no significant difference in above items between preoperative and postoperative at 2 weeks,final follow-up. Postoperative at 2 weeks and final follow-up, there was significant difference in anterior cervical curvature angle between two groups (P<0.05). Postoperative JOA score had obviously improved in all patients, at 3 months after operation and final follow-up, anterior fusion group was better than that of posterior laminoplasty group (P < .05).

CONCLUSIONThe anterior sublevel fusion can effectively restore cervical anterior column height, and compared with the posterior cervical laminoplasty, it can obviously improve the spinal cord function. It is an effective method for the multilevel cervical spondylotic myelopathv.
