Scleroma is a chronic, specific granulomatous disease that affects the head and neck mucosa. Its common sites are nose larynx; however, it might affect other areas. One of rare to be affected middle ear mastoid cavity, for which term otoscleroma was coined. We present such case in this report. A 47-year-old patient with history both old laryngoscleroma recent Rhinoscleroma. He presented symptoms discharge facial palsy. Examination revealed complete nerve palsy an external auditory canal...
Purpose: To study the potential use of human anterior lens capsule as a scaffold for stem cell transplantation in treatment limbal deficiency. Methods: Limbal biopsies and capsules were obtained (same eye) from 30 patients during cataract surgery. Biopsies suspended Dulbecco modified Eagle medium under sterile conditions stored at 4°C.

Background. Wide-necked and non-saccular aneurysms are difficult to treat with coil embolization. The use of stents has expanded the role endovascular treatment. Methods. A retrospective study 43 patients wide-necked, fusiform or blister treated stent-assisted coiling stent alone. review medical files images allowed retrieval following patient characteristics: (1) age gender; (2) aneurysm characteristics (site, size, status (ruptured versus unruptured)); (3) coils used; (4) type stent; (5)...
To evaluate the audiological aspects of vestibular schwannoma (VS) patients with normal hearing.Retrospective study.Quaternary referral center for skull base pathologies.The records on 4,000 who had been diagnosed VS between 1986 and December 2017 were retrospectively reviewed. The included in study ones complied strict normality criteria, as follows: a pure tone hearing threshold (at 6-octave-spaced frequencies from 250 to 8,000 Hz) ≤25 dBHL; word recognition score >90%; interaural...
ABSTRACT PURPOSE: To evaluate the safety, efficacy, and predictability of hyperopic LASIK retreatments. METHODS: This retrospective, consecutive, non-comparative, observational study included 85 eyes that underwent retreatment with 1-year followup. Complete ophthalmic examination distance uncorrected (UCVA) best spectacle-corrected visual acuity (BSCVA), cycloplegic refraction, pachymetry. Patients were divided into two groups according to preoperative spherical equivalent refraction: group...
Background: Psoriasis is a very common, chronic inflammatory and proliferative skin disease with different clinical forms that can affect males females.In recent years psoriasis has been linked lately to systemic associated numerous multi-organ abnormalities complications. related elevated cholesterol levels triglycerides this will be important in the management of it.So their great need study lipid psoriatic patients, which help us evaluate level risk individuals for developing...
Case report: We report the case of a 13 year-old male with bilateral optic neuritis after meningococcal C vaccination.He was treated intravenous corticosteroids, but only showed visual recovery in one eye.A significant limitation his sharp vision remained other eye.Discussion: There have been no previously reported cases vaccination and for this reason we case.It is not possible, however, to exclude some factor etiology neuritis, temporal relationship between suggests cause (
INTRODUCTION: Computed tomography (CT) angiography is currently used as the initial diagnostic tool in patients with spontaneous subarachnoid hemorrhage. Eighty-five percent of hemorrhages are reported literature caused by a ruptured aneurysm, whereas 10% termed nonaneurysmal perimesencephalic hemorrhage and carry excellent prognosis. This retrospective study was conducted to better clarify yield transfemoral catheter cerebral light current high-quality CT angiogram imaging negative cases...
Endoscopic ultrasound-guided biliary drainage is an alternative to failed endoscopic retrograde cholangiopancreatography. Unfortunately, this procedure remains relatively less explored in Egypt due its high cost, lack of adequate training, and the perception increased risk. This study first multicenter Egyptian experience patients with malignant obstruction.We retrospectively reviewed 15 (10 men five women) obstruction who from October 2013 May 2019, following a or inaccessible...
OBJECTIVES To assess the effect of position SS on CI regarding ability to perform posterior tympanotomy, round window visibility, and mastoid pneumatization. MATERIALS AND METHODS This is a prospective study, including 65 adult patients with performed at our center during 2017. We used 3 methods using computed tomography (CT) scan. Lee's line passing through tympanic segment facial nerve. Park's nerve membrane. Our proposed method parallel from external auditory canal Relation pneumatization...
Abstract Purpose To describe the successful use of a PET-CT-based resection guide for treatment auricular squamous cell carcinoma. Case presentation A 69-year-old male presented with painless growing mass in his left ear helix that had been unsuccessfully treated conservatively by another surgeon. An incisional biopsy revealed moderately differentiated carcinoma, and patient was referred to department further management. PET/CT performed, which showed uptake FDG SUV max value T3N0M0 status....
Intracytoplasmic sperm injection includes ovarian stimulation to retrieve mature oocytes, fertilizethem by sperms. Then embryo transfer after endometrial preparation. This could be done fresh or frozen in case of retrieval a high number oocytes.Polycystic ovary syndrome is hormonal disorder which the ovariesproduce abnormal amounts androgens and developnumerous follicles whichthey fail release, leading cycle irregularities, infertility, androgen levels.During polycystic syndrome, it advised...
Cholesteatoma Diagnosis depends on the its high keratin content of which makes them highly hyperintense at b value (800-1000 sec/mm2) and with low values apparent diffusion coefficient (ADC) map similar to that brain parenchyma is same signal characteristics intracranial epidermoid cysts. recurrent cholesteatoma in an operated middle ear cavity may be difficult. HRCT scan conventional MRI have specificity when it comes differentiating granulation tissue from relapsing due lack...
Introduction: Otosclerosis is one of the common causes conductive hearing loss in adults. We describe outcomes our series 85 ears (79 patients) operated a tertiary referral center.Materials: Patients for stapedotomy center from May 2019 to 2023, excluding revision, trauma, chronic ear, previous ear surgeries.Methods: Microscopic was performed all patients. The prothesis used 4.5x0.6 mm whole Teflon. Pure tone audiometry air, bone and air gap 0.5, 1, 2, 4 KHz were calculated pre post...
BACKGROUND The most popular and successful technique for diagnosing preoperative cholesteatomas is diffusion imaging. In spite of its limited capacity to distinguish anatomical features. order create thin-section cross-sectional imaging images, attempts were undertaken merge diagnostic images with corresponding images.PATIENTS AND METHODS: We studied MR 30 patients having CSOM. Imaging techniques included "Non-EPI" "MRI-fluid-sensitive- cisternography". "Fused images" then generated by...

Abstract Background Rhabdomyosarcoma is common in childhood, especially, the head and neck region, yet involvement of temporal bone rare. Case presentation We reported a case an embryonal rhabdomyosarcoma 4.5-year-old boy presenting with external auditory canal polyp purulent otorrhea that later developed grade 6 facial palsy. Imaging showed soft tissue mass involving middle ear, mastoid cavity, parotid gland, parapharyngeal space. Subtotal petrosectomy blind closure was performed nerve...
Middle ear (ME) benign tumors are rare, and among them is meningioma. An ME meningioma might be isolated or merely a lateral extension of CPA We report case with presentation effusion followed by the appearance an aural polyp after repeated myringotomies. Computed tomography (CT) revealed benign-looking mastoid mass. After debulking biopsy, it turned out to However, when MRI was performed, large detected. masses rare; however, they encountered, CT must performed biopsy total removal. In...
