Aural Myiasis in Children and Literature Review
(Tohoku Univ Medical Press, 2005) Yuca, K; Çaksen, H; Sakin, YF; Yuca, SA; Kiris, M; Yilmaz, H; Çankaya, H
Myiasis is a disease caused by fly larvae. The term "myiasis" is derived from the Greek word "myia" meaning fly. Aural myiasis is a rare clinical state and occurs frequently in children. In this article, six children with aural myiasis, caused by the fly larvae, are reported because of unusual presentation. All of the children with aural myiasis were associated with chronic otitis media. In the treatment, a combination of suctioning and alligator forceps was used to remove maggots under the light microscopic field. Additionally, antibiotics were used in all children. Thus, aural myiasis is successfully treated by direct extraction of larvae and application of preventative methods. - myiasis; fly larvae; chronic otitis media; maggots; children (c) 2005 Tohoku University Medical Press.

Effects of Topical Chlorhexidine Applied To the Rabbit Nasal Mucosa
(Elsevier Sci Ltd, 2003) Çankaya, H; Özen, S; Kiroglu, F; Yurttas, V
Objective: To search the effects of administration of various concentrations of a wide-spectrum antimicrobial agent, chlorhexidine, to the nasal mucosa. Material and methods: About 0.20, 0.12, 0.06 and 0.03%, concentrations of chlorhexidine gluconate were applied to the rabbit nasal mucosa as one puff twice a day throughout 5 days. Another group, treated with serum saline to the nose, behaved as the control group. On the fifth day following drug administration, specimens were taken from nasal mucosa of the rabbits and examined under light microscope. Results: As a result of comparison between drug treated group and control group, with increasing drug concentrations progressively increased neutrophil infiltration in mucosa, ciliary loss in cells, and occasional metaplasia were observed. Conclusion: There is a linear, positive and strong association between concentrations of chlorhexidine and its irritative effects on rabbit nasal mucosa. While 0.20 and 0.12% concentrations of chlorhexidine cause excess irritation on the nasal cavity, 0.06 and 0.03% concentrations of chlorhexidine gluconate causes lower irritation and effects on the animals which have experimentally induced rhinosinusitis must be evaluated.

Effects of Topical Mitomycin on Inner Ear
(Tohoku Univ Medical Press, 2002) Çankaya, H; Egeli, E; Kuntsal, L; Ozbek, H; Icli, M
QANKAYA, H., EGELI, E., KUNTSAL, L., OZBEK, H. and ICLI, M. Effects of Topical Mitomycin on Inner Ear: A Light and Electron Microscopic Study. Tohoku J. Exp. Med., 2002, 197 (2), 81-86 - Providing maintenance of myringotomy patency without use of ventilation tubes in the treatment of secretory otitis media has been one of the important study areas. For this reason, laser and Mitomycin C (MMC) are used together in experimental studies. But there has been no ultrastructural studies concerning whether leakage of MMC to middle ear during application of this procedure has an ototoxic effect or not and if so, to what extent. In this study, we searched the ultrastructural changes which occurred in the middle ear by direct applications of MMC to the middle ear for different time durations. The study was carried out over thirty adult guinea pigs without ear diseases. Bilateral myringotomy was performed and MMC was applied only to the right middle ear of each guinea pig. The first group received MMC once for 10 minutes, the second group received it once for 20 minutes, and the third group took it each day for 10 minutes during a one week period. The left ears of the samples were accepted as the control group. On the 8th day, sacrification was carried out. After electron and light microscopy examination, significant changes in the inner ear were observed in the third group though no significant change was observed for the first and the second groups. As a result it was concluded that the application of MMC to the middle ear once for a short duration causes no toxic effect on the inner ear. - mitomycin; secretory otitis media; myringotomy; ototoxicity; inner ear.

Hemangioma With Phleboliths in the Sublingual Gland
(Tohoku Univ Medical Press, 2003) Çankaya, H; Ünal, Ö; Ugras, S; Yuca, K; Kiris, M
Hemangiomas are the most common lesions of the major salivary glands during infancy and early childhood. Changes in blood flow dynamic within hemangioma results in thrombus and phleboliths. There have been a number of reports of hemangiomas with phleboliths in parotid and submandibular glands. We present the first case of a hemangioma with multiple phleboliths in the subligual gland as a cause of submental opacity, and discussed the diagnosis of radiopaque masses in the sublingual and submental regions.

Laryngeal Amyloidosis -: a Rare Cause of Laryngocele
(Elsevier Science inc, 2002) Çankaya, H; Egeli, E; Ünal, Ö; Kiris, M
Laryngocele may be defined as an abnormal dilatation of the saccule of the ventricle and its pathogenesis is uncertain. We report a laryngocele caused by amyloidosis localized to larynx in a 60-year-old male patient. We would like to mention that amyloidosis should be evaluated in the etiology of patients diagnosed as having a laryngocele. (C) 2002 Elsevier Science Inc. All rights reserved.
Local Irritant Effects of Topical Oral Sprays on Oral Mucosa in Mice
(Springer, 2006) Yuca, K; Çankaya, H; Bayram, W; Özbek, H; Kiris, M
Topical oral sprays are frequently used to prevent and manage oropharyngeal inflammation and lesions. This study investigated the histopathologic changes noted in the oral mucosa of mice after topical application of 3 widely prescribed antibacterial products. The 25 animals were divided into 5 groups and treated for 10 days with 2 sprays daily, as follows: group 1 - chlorhexidine gluconate 0.12% * benzydamine hydrochloride 0.15%; group 2 - benzydamine 0.27 mg/0.18 mL * 30 mL; group 3 - chlorhexidine 0.2%; group 4 - fusafungine 1%; and group 5 (cohort) - physiologic serum. On day 10 after drug administration, biopsy specimens were taken from the oropharyngeal mucosa of the tongue, the cheek mucosa, and the tongue base; these were examined under a light microscope and were classified as normal or pathologic. All topical oral sprays produced some degree of histopathologic change, such as hyperplasia, fibrosis, low-grade dysplasia, congestion, or edema. The local irritant effects of topical oral sprays should be considered when treatment is selected for patients with oropharyngeal disorder.
Mri Demonstration of Cervical Spondylodiscitis and Distal Full-Length Bilateral Paraspinal Cold Abscesses Successfully Treated by Drug Regimen Only
(Springer, 2004) Ünal, Ö; Kayan, M; Akpinar, F; Çankaya, H; Akdeniz, N
Objective: Cold abscesses, although common in spinal tuberculosis, are usually localized to the level of infection, follow tissue planes, and may extend into the spinal canal at any level. They may cause symptoms resulting from neurovascular compression, hemorrhage, and direct mass effect. Design and patients: We present an unusual case of cervical tuberculous spondylodiscitis in a 25-year old man with a cold abscesses involving the retropharyngeal, mediastinal, and retroperitoneal areas bilaterally. The abscess tracked from the neck to the psoas muscles bilaterally. Following the diagnosis the patient received 9 months of antituberculous therapy. Results: MRI showed resolution on medical treatment alone. Conclusions: Even in the presence of massive paravertebral cold abscesses medical treatment alone may well suffice for this common worldwide disorder. MRI is ideal for monitoring regression of massive abscesses in deep anatomical locations.
Nasopharyngeal Rhabdomyosarcoma in a Patient With Hypohidrotic Ectodermal Dysplasia Syndrome
(Elsevier Sci Ltd, 2002) Çankaya, H; Kösem, M; Kiris, M; Üner, A; Metin, A
Hypohidrotic ectodermal dysplasia (Christ-Siemens-Touraine syndrome) is characterized by partial or complete absence of sweat glands, hypotrichosis, hypodontia, prominent frontal ridges and chin, saddle nose, sunken cheeks, thick, everted lips, large ears and sparse hair. While association of other ectodermal dysplasia syndromes with tumors such a non-Hodgkin's lymphoma, hamartoma, keratoakanthoma, Merkel-cell cancer, squamous-cell carcinoma, syringofibroadenomatosis has been reported, association of hypohidrotic ectodermal dysplasia and a tumor has not been reported. In a five-year-old male patient admitted with nasal obstruction and nasal mass complaints, we have reported firstly an association of hypohidrotic ectodermal dysplasia and nasopharyngeal. rhabdomyosarcoma.

Papillary Thyroid Carcinoma Presenting as a Giant Cervical Mass
(Royal Belgian Society Ear, Nose, Throat, Head & Neck Surgery, 2005) Yuca, K; Ünal, Ö; Bayram, I; Çankaya, H; Kiris, M
Papillary thyroid carcinoma presenting as a giant cervical mass; a case report. Papillary thyroid carcinoma (PTC) is a relatively uncommon malignancy. The prognosis is generally good and the mortality rate is low. PTC is more common in younger patients; incidence is two to three times higher in women and in individuals with radiation exposure to the neck. We report on a 75-year-old woman with PTC admitted to our clinic for a giant mass in the neck dating back ten years. A hyperintense huge cystic lesion and hypo-intense central solid component were seen on T1- and T2-weighted magnetic resonance imaging. No distant metastasis was present. The PTC was treated surgically and radioiodine (I-131) treatment was applied postoperatively. No recurrence was observed one year later.
Pediatric Intraoral Ranulas
(Tohoku Univ Medical Press, 2005) Yuca, K; Bayram, I; Çankaya, H; Çaksen, H; Kiroglu, AF; Kiris, M
An intraoral ranula is a retention cyst arises from the sublingual gland on the floor of the mouth as a result of ductal obstruction and fluid retention. Many techniques for management of ranulas have been described in the literature. The purpose of this study was to analyze our surgically treated pediatric patients with Intraoral ranulas and to discuss the results in the light of the literature. Nine pediatric patients (six females and three males) with intraoral ranulas surgically treated were analyzed retrospectively regarding their treatment methods and results. The surgical specimens were also re-examined histologically. Seven cases of superficial, protruded and smaller than 2 cm ranulas were treated with marsupialization (unroofing). Two cases who were previously operated and then recurred had bigger than 2 cm ranulas. In these two cases. marsupialization of the ranula plus removal of the sublingual gland was performed. The most common complication was intraoperative cyst rupture of the ranula, which was noted in four cases. A recurrence was observed in only one case in the 16th months of follow up period. Our findings show that marsupialization is a suitable and effective method for pediatric intraoral ranulas, whereas in recurrent cases marsupialization of the ranula combined with total excision of sublingual gland may be preferred - ranula: intraoral cyst; sublingual mass, inarsupialization (C) 2005 Tohoku University Medical Press
Pneumatization of the Concha Inferior as a Cause of Nasal Obstruction
(int Rhinologic Soc, 2001) Çankaya, H; Egeli, E; Kutluhan, A; Kiris, M
Chronic nasal obstruction is a common disorder. Hypertrophy of the inferior turbinates is responsible for nasal obstruction more frequently than it is commonly thought. A pneumatized inferior turbinate has recently been described as a cause for nasal obstruction and only two cases have been reported until now. Inferior nasal turbinate develops by endochondral ossification of components of the mesethmoid and ectethmoid. The chondral framework of the inferior turbinate consists of a double lamella and two separate ossification centers that develop between the fifth and seventh month of fetal life. The separate ossification centers meet by the eighth fetal month. During ossification, the inferior turbinate detaches from the ectethmoid and becomes an independent bony structure. During that time the epithelium may misinvaginate into double lamellas and such double lamellas formed by the inferior turbinate may become persistent. A patient was referred to our clinic with headaches and nasal obstruction. A CT scan was performed which showed that the right lower concha was pneumatized. The headache of the patient disappeared after partial resection of the the lower and middle turbinate.

Retrospective Analysis of Our Cases With Sudden Hearing Loss
(B C decker inc, 2003) Kiris, M; Çankaya, H; Içli, M; Kutluhan, A
Objective: To determine the prognostic factors and healing ranges of patients treated for sudden hearing loss (SHL). Patients and Methods: In our study, 33 patients treated for SHL were evaluated between March 1995 and October 2001 retrospectively. After the routine examinations, first audiograms were done. The audiograms were classified as hearing loss in low frequencies, high frequencies, and flat using the Shey and Rubin classification systems. All patients were treated with the same standard regimen. The benefits of treatment were evaluated with the Siegel classification. Results: Various amounts of hearing gains were obtained in 17 of 21 patients treated in the first 5 days. No gain was obtained in 5 of 12 patients, who re-presented after the first 5 days of SHL. There was a statistically significant difference between the two groups (p = .005). There was hearing gain in all nine patients who had upward-sloping type of audiograms. Hearing gain was obtained in 8 of 12 downward-sloping type and 7 of 12 flat-type audiograms. There was a significant difference between the raising type group and the other groups (p = .04 and p = .014). Also, in 6 of 14 patients with vertigo and in 4 of 12 with bilateral sensorineural hearing loss (SNHL), there was no gain. Conclusion: The prognosis of SHL is found to be better in patients who present early and mild SNHL and unilateral cases and worse in vertigo, bilaterally severe SNHL, and childhood.
