Ewing sarcoma is a rare tumor in head and neck area. We demonstrate a rare case of sinonasal Ewing sarcoma initially suspected as olfactory neuroblastoma. After the surgery and immunohistochemical studies, it was accurately diagnosed as Ewing sarcoma. We would like to emphasize the possibility that Ewing sarcoma may originate from the head and neck area, and hence, it is important to use appropriate techniques for accurate diagnosis and treatment.

Plunging ranula is occured in about 10% of all ranula cases although surgery is the first choice therapy. However, frequent recurrences of the disease due to insufficient surgery have been reported, and various therapies have been designed in addition to surgery. We here report a case on whom we conducted intralesional injection of OK-432 for recurrent plunging ranula. A 36-year-old man was admitted who had a 2-months history of swelling of right submandibular area. He had been operated for right plunging ranula twice, 7 years ago. Under fluoroscopic guidance, contents of the ranula were aspirated and OK-432 solution was injected twice with 3-week interval. Examination after 6 weeks showed that the cystic ranula seen before therapy had disappeared completely and no recurrence was encountered after 18months. Therefore the intralesional injection of OK-432 is effective method for treatment of the plunging ranula.

Septoplasty/septorhinoplasty is a common ear, nose and throat procedure offered for those patients with deviated septum who are suffering from nasal obstruction and functional or cosmetic problems. Although it is a basic and simple procedure, it could lead to catastrophic complications including major skull base injuries which result in cerebrospinal fluid (CSF) leaks. We describe two different cases of traumatic CSF leaks following septoplasty/septorhinoplasty at two different sites. The first patient suffered a CSF leak following septoplasty and presented to Alexandria University Hospital. The leak was still active at presentation and identified as coming from a defect in the roof of the sphenoid sinus and was repaired surgically. The second patient presented 4 days after her cosmetic septorhinoplasty with a CSF leak and significant pneumocephalus. She was managed conservatively. Understanding the anatomical variations of the paranasal sinuses and implementing proper surgical techniques are crucial in preventing intracranial complications when performing either septoplasty or septorhinoplasty. A good quality computed tomography of the nose and paranasal sinuses is a valuable investigation to avoid major complications especially CSF leaks following either procedure.

Papillary thyroid carcinoma (PTC) is the most prevalent type of thyroid cancer. In contrast, thyroid lymphoma is a very rare disease. Concurrent onset of both is very rare in the thyroid gland. Ultrasound (US)-guided Fine needle aspiration (FNA) is a useful diagnostic tool, but occasionally pathology results may change after the surgery. A 56 years old woman visited with Hashimoto's thyroiditis and nodule on the thyroid gland isthmus on US exam. US-guided FNA was performed at thyroid nodule and diagnosed as PTC. The patient underwent total thyroidectomy. The pathological findings revealed a mucosa associated lymphoid tissue (MALT) lymphoma accompanied with PTC. Authors report this unusual case with a review of literature.

It is challenging to achieve sufficient hearing gain in patients with mixed hearing loss. In chronic middle ear diseases, conventional passive reconstructive surgeries often result in suboptimal hearing gain and additional hearing aids may have limitations due to insufficient sound amplification, occlusion effect, acoustic feedback, and skin irritation. Middle ear implantation (MEI) using Vibrant Soundbridge (VSB) is another option for auditory rehabilitation in mixed hearing loss as well as sensorineural hearing loss. The floating mass transducer of VSB can be placed on various middle ear structures either directly or using different types of couplers in order to deliver vibratory mechanical energy to the cochlea. We report a patient who presented with bilateral mixed hearing loss due to chronic otitis media and had limitations using conventional hearing aids in the worse hearing ear. The patient was successfully treated with MEI using the Bell coupler together with middle ear surgery in a single step.

Background and Objectives The purpose of the present study was to evaluate the usefulness of a posterior-based buccinator myomucosal flap (the Bozola flap) for the reconstruction of oral cavity defects after tongue cancer resection. Subjects and Method Fifteen patients who underwent from 2014 to 2016 reconstruction of the oral cavity with a Bozola flap after surgical management of tongue cancer were enrolled in the study. Patient characteristics, surgical outcomes, and complications associated with the Bozola flap were evaluated. Results The flap was successfully harvested and transferred in all patients. The mean flap harvesting time was 25.3 min. The donor site was closed primarily in 14 patients, and a buccal fat pad flap was used in one patient. Although partial necrosis of the flap occurred in two patients, no other major complications were noted. Conclusion The results of this study demonstrate that the Bozola flap is a good option for reconstruction of moderate sized oral cavity defects in tongue cancer patients.

Pilomatricoma is a benign neoplasm of the hair follicle origin which most common occur in the head and neck, particularly in the cheek and preauricular region. This neoplasm is superficially located and stony, hard consistency on palpation and sometimes shows reddish or bluish discoloration on the overlying skin. The diagnosis is confirmed by histopathologic examination. Radiologic evaluation is little diagnostic and fine needle aspiration biopsy often misdiagnose because both tissues from basaloid cell component and shadow cell component should be obtained for correct diagnosis. And Otolaryngologist should consider the possibility of philomatricoma when childhood or early adulthood persion visits with hard, supferficial mass on the parotid or cheek area. The treatment of choice is surgical excision with clear resection margin. In many instances, overlying skin excision is needed. We report 4 cases of philomatricoma arising from preauricular, cheek and posterior neck.

Midline neck masses have numerous origin and it is important to diagnose correctly for management. A clinical analysis of 29 cases of midline neck masses confirmed by histopathological examination was done retrospectively during the last 5 years. The results were followings; 1) Of 29 cases, thyroglossal duct cyst was most frequent(17 cases, 58.6%) and non-specific lymphadenopathy was the next(4 cases, 13.8%). 2) Midline neck masses were most frequent on the suprahyoid area(12 cases, 41.4%) and hyoid area was the next(7 cases, 24.1%). 3) Two thyroglossal duct carcinoma was included in 17 thyroglossal duct cyst. 4) Seventy percent of thyroglossal duct cyst was present on hyoid and infrahyoid area.

Thyroid hematoma secondary to a blunt trauma is a rare problem. Despite the rarity, it can be a life-threatening condition with tracheal compression. Both surgical exploration and conservative management have been suggested for thyroid hematoma. However, there is still controversy on the optimal treatment. A 67-year old man who progressed severe dyspnea and neck swelling was transferred to the emergency department with a blunt anterior neck trauma after traffic accident. Contrast enhanced neck computed tomography scan showed huge hematoma within the right thyroid gland and slight tracheal deviation without prominent airway obstruction. One day later, anterior neck swelling was aggravated and the patient was intubated to prevent airway obstruction. After 3 days, hematoma resolution was revealed and extubation was done. We report this case with a review of literature.

Deep neck infections mean infection in the potential spaces and facial planes of the neck, either abscess formation or cellulitis. Deep neck infections are caused by dental, salivary gland, pharyngeal and tonsillar infections. Sometimes, deep neck infection may be caused by tuberculosis in case of immunodefiecient patients. Acquired immunodeficiency syndrome(AIDS) is a disease associated with defective cell-mediated immunity after infected with human immunodeficiency virus(HIV). The chance of opportunistic infection in patients of AIDS increases as the level of immunodeficienty progresses. Human immunodeficiency virus infection is the most single significant risk factor for progression of pulmonary tuberculosis to extrapulmonary sites. In patients infected with HIV, the rate of extrapulomonary tuberculosis rises upto $60\%$. We report a case of a 47 year old male patient with AIDS associated with deep neck infection by tuberculosis.
