Split-thickness calvarial bone is still a versatile graft in reconstruction of the forehead region. Although a low rate of side effects in harvesting calvarial bone grafts are in general expected, one has to be aware of dural lesions occuring in the donor site during craniotomy.

Background: In this study, we aimed to evaluate the benefit of performing of tonsillectomy in patients with raised serum ASO titre only in absence or presence of group A beta heamolytic streptococci (GABHS) in throat swab. Materials and methods: In this prospective cohort study, 196 patients below the age of 14 were suffering from non-specific streptococcal infections, without fulfilling the clinical parameters used for the diagnosis of chronic tonsillitis 156 patients had a raised ASO titre above 200 iu/ml. Throat swab culture was performed in all patients. Results: The results showed that out of the 156 patients, 52 had positive throat swab for GABHS. All of the patients underwent tonsillectomy. Follow-up of the patients for one year after the operation, 88% of the first group with high ASO titre and positive throat swab showed improvement of symptoms; 25% of the second group with high ASO titre and negative throat swab showed improvement of symptoms. Conclusion: Our study shows that isolation of GABHS from the patients tonsils by throat swab along with high ASO titre may be an indication of tonsillectomy in absence of any other indications.

Background Respiratory distress is recognized as any sign of breathing difficulty in infants. Some congenital anomalies present immediately with airway distress, while others are asymptomatic or discovered later in infancy or childhood. Our objectives are to detect different laryngeal causes of respiratory distress in infants and to measure the relative risk of some variables like age, sex, family history, and other congenital anomalies for developing laryngeal causes of respiratory distress. This observational cross-sectional study was carried out during the period from June 2017 to December 2018 at Children’s University Hospital. The study included 80 infants who presented with respiratory distress and admitted to the hospital. All patients subjected to a detailed history from their parents and full general and ENT examinations. X-ray, MSCT neck or direct laryngoscope were carried out in selected cases. Results As regard age, 58% of cases were between 1–6 months, 28% of cases between 6 months and 1 year, and 14% between 1–2 years. Laryngeal causes of respiratory distress among infants were distributed as follow: 70% laryngomalacia, 18% subglottic stenosis, 8% laryngeal web, and 4% of cases were caused by vocal fold paralysis (VFP). The laryngeal causes of respiratory distress did not reveal any statistically significant difference among different age groups or between both genders (P = 0.257, 0.286; respectively). Also, there was no statistically significant difference between infants with positive family history and those without as regard the laryngeal causes of respiratory distress (P = .378). Conclusion The majority of respiratory distress cases (58%) were between 1–6 months. Bivariant analysis of variables age, sex, family history, and other congenital anomalies showed that they were not potent risk factors for developing laryngomalacia, subglottic stenosis, laryngeal web, and vocal fold paralysis. Laryngomalacia represented the commonest cause of respiratory distress (70%) followed by subglottic stenosis (18%), then laryngeal web (8%), and finally the vocal fold paralysis represented the least percentage (4%). Apart from laryngomalacia, the percentages of other causes seem to vary according to sample size and geographic area of study. So, being familiar with the common causes of respiratory distress in a given region is very essential in order not to miss a potentially life-threatening diagnosis.

Introduction In sphenoid sinuses with ill-defined carotid bony landmarks, accidental injury of the internal carotid artery (ICA) remains one of the most challenging complications, which is particularly reported in the endoscopic endonasal transsphenoidal approaches (EETAs). Objectives To describe an anatomical model for the endoscopic orientation of the juxta-pituitary segment of the ICA in relation to the lateral opticocarotid recess (OCR) as a nearby bony landmark. Methods Dissection was performed progressively, simulating the EETA, in twenty fresh adult cadavers. After reducing the posterior and lateral walls of the sphenoid sinuses, various measurements were taken from both lateral OCRs to “contact points” on the juxta-pituitary segment of the ICA and lateral margins of the pituitary gland. Results The current results have enabled us to divide the region between the lateral OCRs into 3 compartments: 2 lateral parasellar compartments contain juxta-pituitary segments of the ICA with a mean width of 8 mm and a narrow range from 7 mm to 10 mm; and a central intercarotid sellar compartment represents the safe region for bone drilling, showing widely variable widths ranging from 9 mm to 20mm. In all specimens, the variation in the width of the intercarotid compartment correlated with the distance between both lateral OCRs. Conclusion The present study improves surgeon awareness of the variations in the course of the ICA through the EETA along sphenoid sinuses with ill-defined bony landmarks. An appreciation of the measurements taken in the present study can help in operative training, and can also provide a base for future studies to confirm ICA courses associated with a higher risk of injury.
