Effectiveness of intratympanic dexamethasone in otitis media with effusion resistant to conventional therapy.

The aim of this study was to determine the efficiency of intratympanic dexamethasone (ITD) injections as a new treatment modality in otitis media with effusion resistant to conventional therapy. We planned a nonrandomized prospective study to determine the safety and effectiveness of the direct administration of dexamethasone into middle ear cavity with chronic eustachian tube dysfunction. This study was applied on 75 ears of 64 patients aged from 12 to 60 years.

Carotid body tumors and our surgical approaches.

Glomus tumors known as paragangliomas are neoplasms arising from the neural crest. They are named according to the place they originate from. Tumors originating from the carotid body at the carotid bifurcation are called Carotid Body Tumors (CBT).

Myeloperoxydase expression in the pathogenesis of nasal polyps.

Nasal polyps are benign mucosal protrusions that expand into the nasal cavity. There are no any etiological factors that may explain the pathogenesis of nasal polyps but currently inflammation continues to be the major factor. As a result of inflammation, neutrophils become activated and migrate to the inflammatory area and form their bactericidal effects by producing free oxygen radicals.

The protective effects of intratympanic dexamethasone and vitamin E on cisplatin-induced ototoxicity are demonstrated in rats.

Cisplatin ototoxicity is a major dose-limiting factor in the treatment of several neoplasms. Dexamethasone and vitamin E are two slow-acting free radical cleaners, and they have been shown to ameliorate nephrotoxicity and endothelial cell damage in animals receiving cisplatin. The purpose of the study was to determine the effectiveness of vitamin E and dexamethasone as an otoprotectant intratympanically.

The effects of allergic rhinitis on growth, development and body mass indexes in school children.

Objective: The purpose of this study is to determine the frequency of allergic rhinitis (AR) in children and investigate if allergenic rhinitis demonstrated any effects on developmental growth levels and body mass indexes (BMI) in children.

Materials And Methods: 651 students, between 3-15 years of age who were randomly selected from four elementary schools located at Kartal, Istanbul were assessed according to symptoms and the presence of AR by nasal examination with the aid of a 0 degree 2.7 mm hand rigid endoscope.

[Clinical signs and management strategies in thyroid masses].

Objectives: Patients who underwent surgery for thyroid masses were evaluated with regard to clinical symptoms, diagnostic and treatment methods, and the results of treatment.

Patients And Methods: The study included 92 patients (72 women, 20 men; mean age 45 years; range 16 to 71 years). Clinical diagnoses were based on findings of ultrasonography, thyroid function tests, thyroid scintigraphy, and fine-needle aspiration biopsy.

Rosai-Dorfman disease: sinus histiocytosis with massive lymphadenopathy.

A 25-year-old man presented with a 3 month history of a painless mass on the right side of his neck. Physical examination revealed a smooth surfaced, bilobed, 4×3 cm, semimobile mass at the right and 3×2 cm at the left jugulodigastric region. Endoscopic examination of the patient showed a granular tumour in both nasal cavities.

Prevalence of adenoid hypertrophy and nocturnal enuresis in primary school children in Istanbul, Turkey.

Objective: The purpose of this study is to investigate the prevalence of an existing relationship between adenoid hypertrophy and nocturnal enuresis in primary school children.

Methods: The study was performed in four primary schools that were chosen randomly in Kartal, Istanbul. The children's parents were asked to fill out a questionnaire that included questions concerning the associated symptoms of adenoid hypertrophy and nocturnal enuresis.

The effects of radiofrequency and incisional myringotomy on the duration of patency.

Objectives: We investigated whether radiofrequency could prolong the patency of myringotomy.

Materials And Methods: Eighteen guinea pigs were enrolled in this study. Myringotomies were created by radiofrequency in the right ears in the study group using the ENTec coblator plasma surgery system, while the left ears had incisional myringotomies as the control group.

An alternative surgical approach for sublingual dermoid cysts: a case report.

A 52-year-old woman presented with a painless swelling in the floor of the mouth. She stated that it had existed there for 40 years and had undergone a gradual enlargement within the past year. Examination showed a mass, 5x4 cm in size.

Role of the 30 degrees telescope in evaluation of laryngeal masses during direct laryngoscopy.

Visualization of enlarged laryngeal lesions is the most important factor in choosing a surgical technique, especially for partial surgery. For this reason standard microlaryngoscopy, a computed tomography (CT) scan of the larynx, and 30 degrees telescopic microlaryngoscopy were compared during evaluation of the laryngeal ventricul and sub-glottic area. The histopatholgoical findings of the specimens collected under each modality were simultaneously compared.

[The effect of topical mitomycin-C application before or after incisional myringotomy on patency times of guinea pig tympanic membrane perforations].

Objectives: The aim of this study was to investigate the effect of topical mitomycin-C application before or after incisional myringotomy on patency times and to asess its use as an alternative to ventilation tube insertion.

Materials And Methods: Nineteen guinea pigs were divided into two groups. In the study group (n=11), mitomycin-C was applied in a concentration of 0.

Does topical N-acetylcysteine application after myringotomy cause severe otorrhea?

Objectives: The effect of topical N-acetylcysteine (NAC) application was investigated on the healing of acute experimental tympanic membrane perforations.

Materials And Methods: Twenty guinea pigs were used in this study. Under intraperitoneal ketamine anesthesia, incisional myringotomies were performed in the posterosuperior quadrant of the tympanic membranes with a straight otologic hook.

The effect of topical insulin application on the healing of acute tympanic membrane perforations: a histopathologic study.

The aim of the present study was to investigate the effects of insulin on the healing of acute traumatic tympanic membrane (TM) perforations by observing the duration of perforation closure clinically and by examining the TM thickness, fibroblastic reaction, neovascularization and collagenization histologically. In all, 24 adult healthy guinea pigs were used. TM perforations, about 2 mm in diameter were made in the pars tensa of each ear.

An unusual foreign body: a ball bearing in the posterior ethmoid sinus.

Globe perforation was detected in an 18-year-old male patient having total vision loss in the left eye following a car accident. The middle meatus could not be evaluated by sinonasal endoscopy because of edema. Computed tomography showed a foreign body in the left posterior ethmoid sinus, with a trajectory coursing from the globe to the lamina papyracea, and the posterior ethmoid sinus.

Medulloepithelioma is a tumor of the primitive medullary epithelium overlying the ciliary body. Most become evident early in life, and they may be malignant, although distant metastases are rare. The purpose of this report is to describe a malignant nonteratoid neoplasm and its metastasis to the submandibular lymph nodes and to introduce this uncommon neoplasm with otolaryngologists.

A case of carotid body tumor.

A thirty-five-year-old woman had an asymptomatic, slow growing mass that pushed the right tonsilla palatina and was pulsatile in the oropharyngeal region. Magnetic resonance imaging showed a vascular mass at the carotid bifurcation, causing displacement of the external and internal carotid arteries. The diagnosis of a carotid body tumor was confirmed by magnetic resonance angiography.
