Cervical bronchogenic cysts in head and neck region: review of the literature

Congenital cysts of the neck are not uncommon. Most of these are thyroglossal, branchial cleft and thymic cysts. Bronchogenic cysts are uncommon developmental anomalies of the tracheobronchial tree and rarely occur in the neck. More than 70 cases of bronchogenic cysts in the head and neck region have been reported in the literature. We report three cases presenting with neck swelling in the hyoid region that were diagnosed as bronchogenic cysts based on clinical and histopathological findings.

Central giant cell granuloma

The central giant cell granuloma (CGCG) is an uncommon benign bony lesion that accounts for less than 7% of all benign lesions of the jaws in tooth-bearing areas. Its etiology is unknown and its biological behavior is poorly understood. This condition is a slow-growing, asymptomatic lesion that usually affects children and young adults, predominantly females. The following report illustrates the differential diagnosis, surgery, final diagnosis and pathology of a fast-growing CGCG in a 4-year-old girl.

Choanal polyps: an evaluation of 53 cases.

Background The aim of this study was to evaluate our experience on the diagnosis and treatment of choanal polyps (CP). Methods This study consists of 53 patients with CP diagnosed by means of rhinoscopy, nasal endoscopy, computerized tomography, surgical, and histologic findings between 1996 and 2005. Results The origins of the CPs were the unilateral maxillary sinus in 47 patients, simultaneously bilateral maxillary sinus in 2 patients, septum in 2 patients, sphenoid sinus in 1 patient, anterior ethmoid sinus in 1 patient. The most common presenting symptoms were unilateral nasal obstruction, snoring, and rhinorrhea. In the cases of the antrochoanal polyps, the most common preoperative radiological finding was the total opacification of the maxillary sinus. Conclusion Endoscopic approach for complete removal of the CPs is an extremely safe and effective procedure. It should be focused on the detection of the exact origin and the extent of the polyp to prevent recurrence.

Laryngeal amyloidosis with laryngocele

Both laryngocele and laryngeal amyloidosis are uncommon, and simultaneous occurrences of these entities are extremely rare. A case of laryngeal amyloidosis with laryngocele in which the computed tomography (CT) and magnetic resonance (MR) imaging of the larynx, clearly demonstrating both disease processes, is discussed. Diagnosis is confirmed by histopathologic specimens. Only two cases have been reported in the world literature, and this is the third case of laryngeal amyloidosis associated with laryngocele.

Soft Tissue Response of the Larynx to Silicone, Gore‐Tex, and Irradiated Cartilage Implants

Objective: The aim of the study is to compare the efficiency of three different materials (Silicone, Gore‐Tex, and irradiated cartilage) used in medialization laryngoplasty. Local tissue reaction to implants in laryngeal skeleton has been examined for this purpose.

Multiple infiltrating lipomas of the tongue.

A rare case of multiple infiltrating lipomas in the tongue of a 54-year-old man is reported. There have been only five previously reported cases of infiltrating lipoma of the tongue. They were all solitary in nature. The present lesion is the first case reported in the English literature of multiple infiltrating lipoma of the tongue. Because of its infiltrating nature, this tumour may be mistaken for a liposarcoma. Achievement of adequate surgical margins is essential, as the recurrence rate may be as high as 62.5 per cent without complete excision.

Pneumatization of the inferior turbinate

Pneumatization of the inferior turbinate is an extremely rare intranasal anatomical variation. Only a few cases have been reported yet. In this paper we present two cases, one unilateral and one bilateral case with pneumatization of the inferior turbinate.

Effect of intratympanic dexamethasone, memantine and piracetam on cellular apoptosis due to cisplatin ototoxicity.

OBJECTIVE This study aimed to contribute to the literature on the prevention and treatment of ototoxicity due to various drugs and chemicals. MATERIAL AND METHODS This study compared the histological effects of intratympanic dexamethasone, memantine and piracetam on cellular apoptosis due to cisplatin ototoxicity, in 36 rats. RESULTS Dexamethasone and memantine had significant effects on the stria vascularis, organ of Corti and spiral ganglion (p < 0.05). Although piracetam decreased the apoptosis rate, this effect was not statistically significant (p > 0.05). CONCLUSION Dexamethasone and memantine were found superior to piracetam in reducing apoptosis due to cisplatin ototoxicity. Further studies of this subject are needed, incorporating electron microscopy and auditory brainstem response testing.

Adenoid cystic carcinoma of the tongue.

Malignant tumours of the salivary glands in children are extremely rare. We present here a 12-year-old girl initially diagnosed as pleomorphic adenoma on fine needle aspiration biopsy, and adenoid cystic carcinoma (ACC) after the lesion was excised and examined by histopathology. A wide resection of the lesion and bilateral supraomyohyoid neck dissection was performed. To our knowledge this is one of the youngest patients with ACC of the minor salivary glands. Due to its benign histological appearance, the biological agressiveness of ACC is usually underestimated. Although fine needle aspiration cytology (FNAC) is very valuable in diagnosis, cytological variations of pleomorphic adenoma must be considered. ACC of the tongue in a young age group should be treated with wide resection and selective neck dissection if the tumour is localized in places where the risk of metastasis is increased and if there is a clinically palpable lymph node. In such cases the clinician should not avoid radical operations even in a young patient.

A rare anatomical variation of the spinal accessory nerve.

Considerable inter- and intra-individual anatomical differences can be observed during neck dissections. In this case report, we describe an unusual relationship of the accessory nerve to the internal jugular vein.
