Objectives Skull base is an important and a challenging area for surgeons. Success in skull base surgery depends on various factors such as pre-operative evaluation, appropriate surgical technique, anesthesia duration, intraoperative neuromonitorization and wound care. Materials and methods This study was performed in the Anatomy dissection laboratory of M.U. Medical Faculty (Ethical committee approval number 2010-103). Twelve fetuses between 17-33 gestational weeks fixed with formaldehyde were enrolled to the study. Results This study was planned to investigate the cross sectional areas of the sigmoid sinus in three levels to compare the right-left sides and the probable relationship among the levels in fetuses to further delineate the developmental factors on jugular foramen asymmetry. The cross-sectional measurements of sigmoid sinus lumen were done on 3 levels which are described as A1 level; sinodural angle, A2 level; the midpoint between the sinodural angle and endocranial orifice and A3 level as the entrance (endo-cranial orifice) of the jugular foramen. There is a strong positive correlation between left (L) A1 and L A2 and also the same for L A1 and right (R) A2. These strong and positive correlations are all valid between L A2-L A3, L A2-R A2, L A2-R A3, L A3-R A3, R A1-R A2. Conclusion Multicenter studies would be beneficial to investigate the topic with greater number of fetuses also on the different regions for genetic differences.

This study assessed the adequacy of patient data entry in the context of International Statistical Classification of Diseases and Related Health Problems (ICD-10) in the Hospital Information Administration System. It was also aimed to study the adequacy and functionality of the ICD-10 coding in the current Turkish Otorhinolaryngology (ORL) practice in detail. The medical records of 1216 patients who presented to the ORL outpatient clinic between 2012 and 2013 were reviewed. Eight diagnostic codes used by the ORL department were selected from the patient diagnoses report to form patient lists. The accessibility of the ICD-10 codes was analyzed. The data was transferred into the MEdCalc 12.0 software package in a digital medium. The study data was analyzed using frequency tables, Chi-square test, and the two sided likelihood ratio test. Among the ICD-10 codes included in the study, the larynx malignant neoplasm diagnosis (C32.9) was recorded at a rate of 60% and had the greatest ratio of recorded medical history, followed by malignant disorders (C32.3) of the laryngeal cartilage, vertigo (R42) (12.4%) whereas facial asymmetry (Q67.0) (10.5%) had the lowest recorded medical history ratios. There was a significant difference between the recorded and unrecorded patient groups (p [Med-Science 2018; 7(4.000): 873-7]

Objective There is still ongoing research on the relationship of arcuate eminence (AE) and superior semicircular canal (SSC). We aimed to evaluate the precision of predictability of SSC through the morphology of AE via radiological means. Materials and methods This investigation is performed on 12 dry skulls belonging to Mersin University Medical Faculty department of anatomy. Computed tomography (CT) assessment is performed with 0.5-mm-thin sections temporal bone algorithm on dry skulls which were marked with fixated copper wire by scotch tapes on the most prominent part of the middle fossa floor assuming the location of AE. The data are reformatted on the workstation with vitrea 2.0. The distances of the determined three points including lateral (A), apical (B), and medial (C) of the SSC and the copper wire are measured radiologically. Also, the height between the most apical part of the SSC to the floor of the skullbase (H) is measured. The angles between the placed copper wires and the SSC (E) are calculated. The angle between SSC and the midpoint of the IAC (F) and SSC to the sulcus of the greater GSPN (G) were measured. The nearest distance was measured between the most posterior part of the SSC and the point marked by the perpendicular line drawn from the medial border of the petrous bone to the most posterior part of the internal auditory canal (IAC) (D). Results The right and left A, B, and C distances are 2.54+/- 2.75, 3.67+/-3.16, 5.85+/-3.77; 2.92+/-2.24, 3.68+/-2.93, 6.09+/-3.40, respectively. We could not find any statistical significance when the right A, B, and C distances were compared with the left values. Examination of the values revealed that C distance is greater than the A distance of the same side both for right (p=0.040) and left (p=0.022) measurements. The calculated left and right E angles are 30.313+/-12.838, and 35.558+/-18.437 degrees, respectively. Statistical significance was not found between the right and left angles. The right and left F, G angles were 53.17, 47.25; 93.58, 100.92 degrees; and D distances are 8.01, 8.13 millimeters, respectively. Statistical significance was not found when right and left E, F, G angles and D distances were compared. Among 12 left and 12 right sides, the copper wire was found to be nearly overlapping to SSC in two in the right and only one in the left. Conclusion This study reveals that there is a great variability predicting the exact location of SSC through the prominence of AE. Complementary studies are needed with greater number of dry skulls and cadavers. Comparison of different hypothesis including the effect of temporal lobe sulcus is to be discussed to better enlighten the exact relationship of the aforementioned anatomical structures.

This study aims to evaluate the antimicrobial effects of Ecballium Elaterium (E.E) that is topically applied for treatment of rhinosinusitis as a traditional medicine. Pure and extract forms of E.E are applied to the nasal cavity of rats for rhinosinusitis. Nasal mucosa, soft palate and trachea of rats were harvested in the first hour, 3rd day and 3rd week for histopathological evaluation. This experimental study revealed antiinflammatory effects of E.E. It has also been shown that E.E reduced fibrosis. The antiinflammatory effect of all forms of E.E has been found to be at their maximum level in the 3rd day with a decreasing manner to 3rd week. Additionally, pure form of E.E caused severe epithelial loss in hyperacute stage. E.E also reduced fibrosis besides its antiinflammatory effect. The action mechanism of antiinflammatory effect of different levels of extract forms need to be further analysed through related enzymatic pathways by different dose and time studies.

This study aimed to evaluate the antimicrobial effects of the medicinal plant Ecballium elaterium, which is topically applied as a traditional medicine for the treatment of rhinosinusitis. Pure and extract forms of E elaterium were applied to the nasal cavity of rats for the treatment of Streptococcus-pneumoniae -induced rhinosinusitis. The nasal mucosa, soft palate, and trachea of the rats were harvested in the first hour, third day, and third week for histopathologic evaluation. This experiment revealed the anti-inflammatory effects of E elaterium and showed that it reduced fibrosis. The anti-inflammatory effect of all forms of E elaterium was found to reach its maximum level on the third day, decreasing by the third week. We also observed that the pure form of E elaterium caused severe epithelium loss in the first hour after application. The mechanism of the anti-inflammatory effect of different levels of extract forms needs to be further analyzed with different doses and duration of treatment.

Background As the skull base has a complex anatomy, we underline the importance of anomalies for side asymmetry. It is useful to investigate relationship between anatomical structures for the surgical procedure orientations. Dural adherence, enlarged superior petrosal sinus, influence of neural crest cells, and cranial base ossification are among the factors in morphometric growth on skull base. Material and methods Twenty-five fetuses of an estimated gestational age ranging from 17 to 34 weeks were studied in the Anatomy Laboratory of Mersin University Medical Faculty. Craniotomy was made to each fetus and brain hemispheres were dissected. We put plates, passing from the external points of lateral and anterior-posterior borders of fetus heads that are perpendicular to each other. An analytical calculation was formulated for the angle of foraminae to the root of zygoma by using different formulations depending on their posterior or anterior location to the root of zygoma. Statistical method was based on correlation analysis, simple regression, independent 2 group t tests, SPSS20.0, and MedCalc 11.5 (MedicReS, New York, NY). Results Neither side dominance for the jugular foramen, nor the differences of foramen rotundum, spinosum, and ovale to anterior skull wall, root of zygoma, and to midline were found to be significant. Conclusion There is a debate on asymmetry of foramina of the skull base. No certain consensus about the initiation time and the causes of asymmetry in the past was documented. Studies are to be encouraged to further enlighten pre-postnatal factors affecting the fetal skull base morphometrism.

Congenital dacryocystocele is a malformation of the nasolacrimal system. Most of the cases can be successfully treated with conservative treatment options such as sac massage. Congenital dacryocystoceles with concomitant intranasal cysts causing respiratory distress in the newborns are rarely published. In this case report we presented a 2-week-old newborn with bilateral congenital dacryocystoceles causing intermittent respiratory distress. We discuss the importance of nasal endoscopic treatment and multidisciplinary approach for these rare malformations in the light of the current literature.

Introduction Tinnitus is a perception of sound in the absence of an external source and it is a distressing issue. Yoga is a system of mind-body practices with the goal of uniting the body, mind and soul. It has been shown to reduce anxiety and stress, as well as improving the quality of life. Objective The aim of this study is to investigate the effects of yoga in patients suffering from chronic subjective tinnitus. Methods Twelve subjects previously diagnosed with chronic subjective tinnitus were selected for the study. The patients were asked to attend to yoga classes once a week and to practice yoga at home using a worksheet for 3 months. Each yoga class consisted of body exercises (asana), breathing (pranayama) and meditation (shavasana and yoga nidra). Tinnitus scores before and after the yoga classes were compared using the Wilcoxon test. Results Among the 12 patients, there were 4 men and 8 women and their mean age was 52.5 years. The median duration of tinnitus among the group was 5.4 years. There were statistically significant differences in the stress (p = 0.01), handicap (p = 0.004) and severity (p = 0.007) questionnaires scores. Conclusion This study indicated that yoga practices may reduce life stress and symptoms of subjective tinnitus.

Hairy polyp is a rare, benign tumor that comprises ectodermal and mesodermal germ layers. The embryogenesis of hairy polyp is precisely unknown, and concurrently, it has a female predominance. Although hairy polyp is observed in every part of the body; it is frequently located in the nasopharynx and oropharynx. Respiratory distress and feeding difficulties are the most related symptoms. Differential diagnoses comprise hemangioma, teratoma, epidermoid cyst, neuroblastoma, and meningocele. In this report, a seven-year-old patient who was admitted to our clinic with swallowing difficulty because of an oropharyngeal hairy polyp was described.

A wide range of morphological varieties and developmental anomalies of the thyroid gland have been reported in literature such as hypoplasia, ectopy, hemiagenesis, and agenesis. Out of these, the incidence of agenesis of the thyroid isthmus is rare, and very few cases have been reported. In the present case report, a female patient was found with agenesis of thyroid isthmus with thyroid papillary carcinoma in the right lobe. In this article, we report a case of thyroid isthmus agenesis and reviewed the associated literature.
