Background: The inability of anterior cruciate ligament reconstruction (ACLR) surgery to reduce tibial internal rotation causes many problems. A large tibial internal rotation will result in a patellofemoral pain syndrome. This study aimed to introduce a new technique of modified exorotation graft tension at tibial fixation to minimize endorotation, reduce tibial internal rotation, and prevent patellofemoral pain syndrome.Methods: This study was a randomized double-blind controlled clinical trial. ACL rupture patients underwent ACLR surgery between December 2014 and Februrary 2015. They were randomized to standard endorotation group or modified exorotation group. Hamstring autograft was used and fixed with an EndoButton® and bioabsorbable interference screw. Tibial tubercle to trochlear grove (TTTG) was used to evaluate rotation, whereas cartilage oligomeric matrix protein (COMP) was employed to analyze cartilage breakdown. The functional outcome was measured using the Kujala score to assess patellofemoral joint function. Evaluations were conducted before the surgery and at 6 months postoperation.Results: A total of 29 subjects were recruited. Sixteen subjects were allocated into the standard endorotation group, and 13 were assigned to the modified exorotation group. The exorotation group demonstrated better results than the endorotation group in all three parameters: TTTG (p=0.028), COMP (p<0.001), and Kujala score (p=0.015).Conclusion: A new technique of modified exorotation direction of graft tension for ACL reconstructive surgery at tibial fixation showed a significant reduction in tibial internal rotation and cartilage breakdown. The proposed method could significantly improve the functional outcome of those with total ACL rupture.

Background: Juvenile nasopharyngeal angiofibroma (JNA) is a histologically benign, but locally invasive neoplasm occurring most often in adolescent males. These tumors are highly aggressive andare associated with significant morbidity and mortality due to its tendency to bleed. Purpose: To presentevidence based case-report on endoscopic removal of JNA as an alternative technique besides the openapproach. Cases: Three cases of JNA managed endoscopically of their removal and the difference ofclinical symptoms based on the histopathological variation and radiological description analysis, givingbenefits in endoscopic surgical planning. Management: The classical treatment for JNA is surgery,however there are cases in which may indicate radiotherapy or even hormone therapy and gamma knifesurgery. Recent advances in technology enable ENT surgeons to use the endonasal technique as analternative in treating JNA patients. Conclusion: Endoscopic removal of JNA was successfully performedfor T1 and T2 tumor based on Fisch classification. To support a good management for JNA casesendoscopically, carefull considerations should be made to determine accesses toward the predominant attachment of the tumor to sphenopalatine foramen and pterygoid plate.

Acute sinusitis is the most common form of sinusitis, and it causes swelling and inflammation within the nose. The main thing that can causes sinusitis is probably due to viruses, and also can be caused by other factors, namely bacteria, fungi, irritation, dust, and allergens. In this research, the CT scan data attributes will be used for classification and grey wolf optimization-support vector machine (GWO-SVM) will be the machine learning technique used, where the GWO technique will be used to tuned the parameters in SVM. The performance of methods was analyzed using the python programming language with different percentages of training data, which started from 10% to 90%. The GWO-SVM method proposed provides better accuracy than using SVM without GWO.

Latar belakang: Variasi performa pasca implan koklea menunjukkan adanya variasi patologi yang belum dapat dijelaskan melalui pemeriksaan standar pra-operasi. Untuk itu dibutuhkan pemeriksaan yang dapat menunjukkan variasi integritas jaras auditori sebagai petunjuk variasi potensi internal tiap individu. Tujuan: Mendapatkan variasi respons jaras auditori terhadap stimulus listrik pasca implan berdasarkan pemeriksaan Implanted Electrically evoked Auditory Brainstem Respons (Imp-eABR), serta korelasinya dengan faktor internal pra-implan lain berupa usia, luas area n. koklearis dan kemampuan komunikasi pra-operasi. Metode: Kriteria subjek penelitian adalah pasien operasi implan koklea berusia kurang dari 10 tahun, memiliki koklea dan n. koklearis normal, dan pada pasien berusia lebih dari 4 tahun sudah memakai alat bantu dengar minimal 1 tahun. Pemeriksaan Imp-eABR dilakukan terhadap 5 elektrode yang mewakili area apikal, medial dan basal koklea. Dicari hubungan respons dari stimulasi terhadap ketiga faktor internal.Hasil:Pemeriksaan Imp-eABR dilakukan terhadap 28 telinga dari 19 pasien yang dilakukan operasi secara unilateral dan bilateral. Rerata skor total respons Imp-eABR adalah 6,3 + 2,63; dengan 60,7% telinga memiliki skor total kurang dari 8. Uji regresi linear menunjukkan faktor usia, luas area n. koklearis dan kemampuan komunikasi berkorelasi secara bermakna dan dapat memprediksi variasi skor Imp-eABR sebanyak 49,2%. Kesimpulan:Variasi skor total Imp-eABR pada pasien dengan faktor internal pra-operasi menunjukkan adanya patogenesis lain yang mendasari kemampuan transmisi jaras pendengaran retrokoklea terhadap stimulasi listrik dari implan koklea. Faktor internal pra-operasi dapat menjelaskan kurang dari 50% variasi respons Imp-eABR. Kata kunci: Imp-eABR, luas area n. koklearis, implant koklea, integritas jaras auditori ABSTRACT Background:Variations in performance after cochlear implant indicates pathology variations that cannot be explained through standard preoperative examination. Therefore, an examination is needed to show variations in the integrity of auditory pathways as a guide to internal potential variations of each individual. Objectives: To show variations of auditory pathways responses to electrical stimulation from cochlear implant by performing Implanted Electrically evoked Auditory Brainstem Response (Imp-eABR) examination and to find its correlation to age, cochlear nerve area and preoperative communication skills. Methods: Subjects were cochlear implant patients with age less than 10 years, had normal cochlear and cochlear nerve,and patients over 4 years old with history of wearing hearing aids for at least 1 year. The Imp-eABR examination was performed to 5 electrodes representing the apical, medial and basal areas of the cochlea. Results:Imp-eABR examination was performed on 28 ears from 19 patients who underwent unilateral and bilateral surgery. The average total score of Imp-eABR responses was 6.3 + 2.63; with 60.7% of the ears having a total score of less than 8. Linear regression tests showed age,cochlear nerve area,andcommunicationabilitysignificantlycorrelate,it canexplain49.2%ofthevariationinthetotal Imp-eABR score. Conclusion: The variation in the total Imp-eABR score in patients with preoperative internal factors indicated that another pathogenesis also underlines the ability of transmission of the retrocochlear auditory pathway to electrical stimulation from the cochlear implant. Preoperative internal factors can only explain less than 50% of the variation of the Imp-eABR response.

Background: Carotid-cavernous fistula (CCF) is an abnormal communication between the carotid arterial system and the cavernous sinus. It can manifest as proptosis, bruit, corkscrew appearance or other signs. The aims of this study were to evaluate the clinical characteristics and result of CCF therapy.Methods: This is a retrospective study which evaluated the clinical characteristic, outcome of therapy and complications after embolization in CCF patient confirmed by digital subtraction angiography (DSA) from January 2012 to December 2014.Results: Twenty-three patients, 16 male and 7 female, were diagnosed as CCF. Mean age was 26Â±10.5 years old. The most common etiology was trauma (91.3%) with onset ranging from immediately to 17 months after trauma. The frequent ocular manifestations were proptosis, bruit, and conjunctival abnormalities. Other ocular signs were ophthalmoplegia, secondary glaucoma, abnormalities of posterior segment, and decrease of visual acuity. Seventy-eight percent patient was type A CCF. Fifteen patients underwent embolization, 3 patients couldnâ€™t be embolized then treated by manual carotid compression, 5 patients were still waiting for schedule of embolization. Clinical signs of 63% patients were improved in 1 week after embolization. After several months, 2 patients with carotid compression was improved and 1 patient had persistent signs. Complications of embolization include transient sensoric aphasia (1 pasien) and central retinal vein occlusion (2 patients).Conclusion: Clinical characteristics of CCF in this study were not different with previous descriptive studies and most cases showed improvement in clinical signs after therapy.

Background: Carotid cavernous fistula (CCF) is a rare life-threatening. Rapid endovascular technical development has provided as a safe and effective treatment strategy for direct CCF (DCCF). Coiling treatment is a promising endovascular procedures solution in DCCF. Method: A comprehensive PubMed, Clinical key, and Ophthalmology database search was conducted using appropriate keywords (direct carotid cavernous fistula, endovascular treatment, embolization, and coil). Inclusion criteria was only article in English. Results: Nine studies (8 case series and 1 cohort study) were found suitable. From these results, endovascular coiling treatment can close the fistula with radiological evaluation and improvement in clinical symptoms in most of studies (90% and 88%, respectively). Post-operative and long-term complication were reported in some studies. Conclusion: Efficacy of endovascular coiling embolization appears promising in management of DCCF. There were no intra-operative complications and post-operative complications, such as unraveled micro-coil. The recurrence fistula rate of 4% is common in fistulas with larger tears associated with a larger CCF.
