AIm: Acromegaly is a chronic disorder characterized by enhanced growth hormone (GH) secretion and elevated insulin-like growth factor-I (IGF-I) levels, usually caused by pituitary adenomas. In this retrospective study, we reviewed our experience with endoscopic endonasal transsphenoidal surgery (EETS) with in remission rates using the 2010 consensus criteria, predictors of remission and associated complications. mATERIAl and mEThods:The authors retrospectively analyzed data from 56 acromegalic patients who underwent pure EETS. Tumors were classified according to size and suprasellar/parasellar extension. The criteria of remission were GH levels < 1 ng/mL randomly, < 0.4 ng/mL after oral glucose tolerance test and normal IGF-I levels for age and sex within the first 3 and 6 months after surgery. REsulTs:Biochemical remission was achieved in 4 of 5 microadenomas (80%) and in 33 of 51 macroadenomas (64.7%). The total remission rate was 66.1% (37 of 56 adenomas). Age, gender and suprasellar extension did not affect the remission rate. However, cavernous sinus invasion, sphenoid sinus invasion and history of prior surgery were associated with lower rates of disease control.CoNClusIoN: EETS represents an effective and safe option for the treatment of patients with acromegaly. High disease control rates and a small number of complications are some of the most important points related to the technique.KEywoRds: Acromegaly, Endoscopic transsphenoidal surgery, Remission, Predictive factors ÖZ AmAÇ: Akromegali genellikle hipofiz adenomuna bağlı gelişen büyüme hormonu (GH) aşırı salınımı ve yükselmiş insülin benzeri büyüme faktörü-1 (IGF-I) ile karakterize kronik bir hastalıktır. Bu retrospektif çalışmada, 2010 remisyon kriterleri kullanılarak endoskopik endonazal transsfenoidal cerrahi (EETC) ile tedavi edilen akromegali hastalarında remisyon oranı, remisyonu etkileyen faktörler ve ilgili komplikasyonlar sunuldu. yÖNTEm ve GEREÇlER: Pür EETC ile tedavi edilmiş 56 GH salgılayan hipofiz adenomu tanılı hastalar retrospektif olarak incelendi. Adenomlar boyutlarına göre mikro/makroadenom olarak ve suprasellar/parasellar yönelimlerine göre sınıflandırıldı. Hastalığın remisyon kriterleri olarak, rastgele bakılan GH düzeyi < 1 ng/mL, oral glukoz tolerans testi sonrası GH düzeyi < 0,4 ng/mL ve cerrahi sonrası ilk 3-6 ay arasında bakılan IGF-I düzeyinin yaşa ve cinsiyete gore normal olması kabul edildi.BulGulAR: 5 mikroadenomun 4'ünde (%80), 51 makroadenomun 33 (%64,7) ünde remisyon sağlandı. Hastaların tümü incelendiğinde, remisyon oranı 56 hastada 37 (%66,1) olarak bulundu. Yaşın, cinsiyetin ve suprasellar büyümenin remisyon oranlarına etkisinin olmadığı görüldü. Ancak daha önce cerrahi geçirmiş olmak, kavernöz sinüs ve sfenoid sinüs invazyonunun remisyon oranlarını azalttığı saptandı. soNuÇ: EETC, akromegalinin tedavisinde etkili ve güvenli bir yöntemdir. Bu teknikle yüksek başarı ve düşük komplikasyon oranlarına ulaşmak mümkündür.
IntroductionAmeloblastoma is a benign but locally aggressive tumor of odontogenic epithelial tissue. Reports of radiotherapy treatment modalities are limited in the literature.Case presentationA thirty-five year old male presented with complaints of headache radiating to his face for about six months and impaired vision. The patient’s Positron Emission Tomography (PET) showed a mass in the left maxillary sinus extending to the nasal cavity and invading the adjacent tissues. An R2 (macroscopic residual tumor) surgical resection performed to debulk the tumor. Due to the recurrence and residual mass, the patient was treated with helical tomotherapy. At 2 months post-radiotherapy, patient’s vision returned to normal. PET scan showed a significant reduction in lesion size 12 months post-radiation.ConclusionIn cases of ameloblastic carcinoma with, post-surgical recurrence or patients not suitable for surgical treatment, helical tomotherapy can be an effective treatment option.
Objective:The most common used technique for posterolateral cervical disc herniations is anterior approach. However, posterior cervical laminotoforaminomy can provide excellent results in appropriately selected patients with foraminal stenosis in either soft disc prolapse or cervical spondylosis. The purpose of this study was to present the clinical outcomes following posterior laminoforaminotomy in patients with radiculopathy.Materials and Methods:We retrospectively evaluated 35 patients diagnosed with posterolateral cervical disc herniation and cervical spondylosis with foraminal stenosis causing radiculopathy operated by the posterior cervical keyhole laminoforaminotomy between the years 2010 and 2015.Results:The file records and the radiographic images of the 35 patients were assessed retrospectively. The mean age was 46.4 years (range: 34-66 years). Of the patients, 19 were males and 16 were females. In all of the patients, the neurologic deficit observed was radiculopathy. The posterolaterally localized disc herniations and the osteophytic structures were on the left side in 18 cases and on the right in 17 cases. In 10 of the patients, the disc level was at C5-6, in 18 at C6-7, in 2 at C3-4, in 2 at C4-5, in 1 at C7-T1, in 1 patient at both C5-6 and C6-7, and in 1 at both C4-5 and C5-6. In 14 of these 35 patients, both osteophytic structures and protruded disc herniation were present. Intervertebral foramen stenosis was present in all of the patients with osteophytes. Postoperatively, in 31 patients the complaints were relieved completely and four patients had complaints of neck pain and paresthesia radiating to the arm (the success of operation was 88.5%). On control examinations, there was no finding of instability or cervical kyphosis.Conclusion:Posterior cervical laminoforaminotomy is an alternative appropriate choice in both cervical soft disc herniations and cervical stenosis.
Background:Low back and leg pain due to lumbar discal hernia (LDH) is an important health issue. Current evidences support surgery in carefully selected patients who have failed conservative treatment and do not exhibit any psychosocial overlay. However, as known, sometimes it may be still very difficult to normalize the life qualities of patients for long times. Now different surgical methods for LDH are in use with new technological materials. One of them is lumbar disc prosthesis. In this study, the radiological and clinical effects of using lumbar disc prosthesis were evaluated with comparing patients underwent simple lumbar microdsicectomy. The purpose of this study is to reveal whether inserting the disc prosthesis into the intervertebral distance after lumbar microdiscectomy is beneficial or not both radiologically and clinically.Methods:A total of 114 patients were analyzed; the first cohort consisted of 57 patients who received a lumbar discectomy at a single level along with the implantation of a disc prosthesis and the second consisted of 57 patients only received a lumbar discectomy at a single level. These 2 groups were studied by comparing the disc space on the level of carried out operations with pain scales, foramen diameters of coming about related roots preoperatively and postoperatively at 3 years.Results:One of the significant results of the implementation of the disc prosthesis is fulfilment of a healthy disc height again after microdiscectomy due to LDH. We concluded that fulfilment of a healthy disc height with lumbar disc prosthesis was clinically beneficial for patients underwent microdiscectomy.Conclusions:Based on the results obtained in this study, it can be concluded that the implantation of a disc prosthesis in appropriate patients is more favorable regarding pain and spinal physiology when compared to simple microdiscectomy.
Fibrous dysplasia (FD) is a rare, benign disease of unclear etiology where normal bone is replaced with abnormal fibrous and weak osseous tissue. Any bone of the skeleton might be involved but skull is one of the most commonly affected sites. Fibrous dysplasia is known to be caused by a genetic mutation leading to inappropriate proliferation and differentiation of osteoblastic cells. However; it is not known whether any triggering factor exists which might contribute to this genetic mutation. The authors postulated that trauma might be a triggering factor for this disease. Trauma, as a triggering factor, has not been reported to be clearly linked to FD in the literature so far. Through this perspective; the authors report a patient of fronto-orbital fibrous dysplasia developing 6 years after a fronto-orbital skull fracture, at the same localization of the fracture line.
