Choice of cochlear implant side in a paediatric population.

OBJECTIVE: To compare the effect of right- or left-sided cochlear implantation on listening skills in a paediatric population. METHODS: A retrospective analysis was conducted on the listening skills performance data of children who were operated on and followed up at the Çukurova University Department of Otorhinolaryngology between 2007 and 2011. Sixty-three patients were included in the study. Patients were evaluated using the Listening Progress Profile, the Meaningful Auditory Integration Scale and the littlEARS test. RESULTS: The mean age of the children was two years (range of one to five years). Twenty-nine patients were male and 34 were female. Twenty-eight patients were implanted in the right ear and 35 in the left ear. There were no statistically significant differences between right and left ear implantees in terms of listening skills performance. CONCLUSION: This study indicates that the choice of cochlear implant side is not crucial for the development of listening skills.

Auricular cutaneous leishmaniasis mimicking neoplastic disease.

OBJECTIVE: Leishmaniasis comprises a group of diseases transmitted by the bite of infected sand flies. There are three basic clinical forms of leishmaniasis: cutaneous, mucocutaneous and visceral. Leishmaniasis may mimic neoplastic lesions and other infectious diseases because of similar disease localisation, physical characteristics and histopathological findings. CASE REPORT: A 35-year-old man was referred to our clinic with a presumed diagnosis of angiolymphoid hyperplasia of the auricle; however, this lesion proved to be cutaneous leishmaniasis. The definitive diagnosis was reached by identifying the parasites on smears obtained from the lesion. CONCLUSION: It should be borne in mind that cutaneous leishmaniasis presenting as isolated auricular lesions may mimic neoplasia. In the present case report, we discuss auricular cutaneous leishmaniasis and we review the relevant literature.

Salivary duct carcinoma ex pleomorphic adenoma: analysis of the findings in fine-needle aspiration cytology and histology.

Salivary duct carcinoma (SDC) is an uncommon and highly aggressive neoplasm that reveals histopathologic features resembling infiltrating duct carcinoma of the breast and prostate. SDC arising on the basis of preexisting pleomorphic adenoma (PA) is very rare. This report describes the fine-needle aspiration (FNA) cytology of a case of SDC ex PA. FNA smears were cellular with cells with large, pleomorphic nuclei, some prominent nucleoli, and finely vacuolated cytoplasm. The neoplastic cells were forming groups, sheets, and papillary structures and a cribriform pattern was present in some sheets. Mitotic figures were frequently seen. Necrosis was prominent in the background. Histologic sections of the tumor revealed areas of comedo carcinoma, papillary carcinoma, and infiltrative carcinoma as well as multiple foci of PA. The presence of a cribriform pattern, tumor cells resembling breast ductal carcinoma cells, and a necrotic background are helpful features for an accurate cytodiagnosis of SDC.

Pharyngocutaneous fistula following laryngectomy.

BACKGROUND: Pharyngocutaneous fistula (PCF) following laryngectomy is a serious complication, and its incidence varies from 7.6% to 50%. Despite the relative frequency of this complication, there is still uncertainty about the predisposing factors. METHODS: A retrospective study was performed in 295 patients who underwent total laryngectomy. RESULTS: Of the 295 patients, 37 (12.5%) developed PCF. The contributing factors,--such as early oral feeding postoperatively, prior radiotherapy or tracheostomy, accompanying neck dissection,--and the surgical technique failed to show a statistically significant effect. There was statistically significant association between tumor size and PCF formation. Also, when the suture materials used for the closure of the pharynx were compared, catgut showed a higher rate of PCF formation than vicryl (p < .05). CONCLUSIONS: The vicryl, when used as a suture material for the closure of the pharynx, seemed to decrease the fistula rate significantly, compared with catgut. Also, tumor stage was found to have a significant role in PCF formation, but no statistical significant difference could be demonstrated for other investigated parameters. We believe that after total laryngectomy, oral feeding can be started at the third postoperative day without increasing morbidity, which makes the patients feel more comfortable and confident without nasogastric tube.

Reflex sympathetic dystrophy following neck dissections.

PURPOSE: Reflex sympathetic dystrophy (RSD), which is a disorder that occurs after injury or surgery on the extremities, has not been reported as a complication of neck dissections until now. A group patients with head and neck cancer have been examined to determine the incidence of RSD in neck dissections. PATIENTS AND METHODS: Forty-six patients with head and neck cancer, who had undergone neck dissections together with the removal of the primary tumor, were evaluated for RSD on their routine controls. RESULT AND CONCLUSION: The presentation of RSD in two patients who were treated with radical neck dissection is probably a result of sympathetic hyperactivity that is secondary to surgical trauma.

Ultrastructure of the nasopharyngeal orifice epithelium of the eustachian tube in otitis media with effusion.

Epithelial changes in nasopharyngeal orifice of eustachian tube in 15 patients with otitis media with effusion (OME) were studied. Ultrastructural examination of the epithelium revealed distinct alterations in the ciliated cells, intermediate cells and in the columnar cells with microvilli. The ciliated cells were the predominant cell type in the epithelium and were characterized by compound cilia and apical cytoplasmic bulgings with fine granular content. The intermediate cells showed more prominent lateral cytoplasmic bulgings. Cytoplasmic bulgings of both cell types eventually pinched off and set free as cytoplasmic bodies, similar to the cytoplasmic bodies derived from lymphocytes. As a result of epithelial destruction, the lumen of nasopharyngeal orifice was occupied by epithelial cellular debris among which leucocytic cells and cytoplasmic bodies with fine granular content. This accumulation in the lumen probably developed as a result of defective mucociliary activity which is due to compound cilia formation in the ciliated cells. Moreover, ultrastructural resemblance of cytoplasmic bodies derived from ciliated cells, intermediate cells and leucocytic cells indicates the possible role of these cells in common immune defence mechanisms in chronic otitis media with effusion.

Serum levels of tumor necrosis factor in squamous cell carcinoma of the head and neck.

PURPOSE: Tumor necrosis factor (TNF)-alpha is a multifunctional cytokine that influences the clinical outcome in a number of diseases. This study was undertaken to evaluate its role in the differential diagnosis of malignant and benign tumors and in the follow-up of patients. We also studied the correlation of TNF-alpha levels with the stage and differentiation of the diseases. METHODS: In this study, serum levels of TNF-alpha are determined by the immunoradiometric assay method in 26 patients with head and neck cancer, and results are compared with 8 control patients with benign diseases. In both groups, serum samples were taken before and after the therapy. After centrifugation, the sera was stored at -70 degrees C until analyzed. TNF-alpha levels were measured by TNF-alpha immunoradiometric assay (IRMA) kit (Medgenix, Diagnostics SA, Belgium). RESULTS: The pretreatment mean value of TNF-alpha in the study group (814.1 pg/mL) was almost 100 times higher than in the control group (8.6 pg/mL) (P = .001). It was also noted that posttreatment mean value (94 pg/mL) was significantly lower than pretreatment mean value in the study group (P = .001). No statistically significant difference was found between serum TNF-alpha levels and the stage and differentiation of the tumor. CONCLUSION: The serum levels of TNF-alpha may be an efficient tumor marker in the diagnosis of patients with head and neck cancer.

Acyclovir in the treatment of recurrent respiratory papillomatosis: a preliminary report.

INTRODUCTION: In this study, we evaluate the effect of acyclovir in the treatment of recurrent respiratory papillomatosis (RRP), in addition to CO2 surgery. MATERIALS AND METHODS: We include 12 patients who had aggressive RRP and required at least three prior endoscopic surgeries in this study. Acyclovir treatment started the day after the surgery. During the planned treatment period of 6 months, patients older than 5 years were asked to take the daily dose of 800 mg, and those younger than 5 years were asked to take 400 mg. RESULTS: Nine of 12 patients were disease free during the follow-up periods, which ranged from 14 to 25 months with a mean of 18 months. Only 3 patients who used the drug inadequately required reoperation. CONCLUSION: Because of the specific viral origin of RRP, we hope that addition of acyclovir to surgery will preclude or at least decrease the number of recurrences in this potentially fatal disease.

Alveolar soft part sarcoma of the tongue.

In this report a 13-year-old girl with characteristic clinical and pathological features of alveolar soft part sarcoma of the tongue is presented. Alveolar soft part sarcoma is a rare malignant tumor of unknown origin. Forty eight cases of alveolar soft part sarcoma have so far been reported in the head and neck region. Median survival reported for all sites of the body is 79 months following various modes of therapy. In this case, the treatment was surgical excision of the mass combined with radiotherapy and chemotherapy. The patient has been asymptomatic for the past 12 months.

Extramedullary leukemia with central facial palsy originated from poorly differentiated abdominal lymphoma.

An 8-year-old boy was presented with central facial palsy caused by extramedullary leukemia which had originated from poorly differentiated abdominal lymphoma. On cerebral tomographic scanning, there were adherences in the basal area of the brain. The occurrence of central facial palsy is very rare in childhood leukemia. However, in this case facial palsy was central in type and appeared as the presenting sign. The occurrence of central facial palsy was confirmed by the absence of clinical, radiological and audiological signs of peripheral involvement. The contralateral stapedius reflex test (500, 1000, and 2000 Hz) was present in this case.
