Malignant otitis externa.

Objective: Malignant external otitis is a severe infection of the external auditory canal and skull base, which most often affects elderly patients with diabetes mellitus. This disease is still a serious disease associated with cranial nerve complications and high morbidity-mortality rate. Malignant otitis externa requires urgent diagnosis and treatment.

Encephalomalacia in the frontal lobe: complication of the endoscopic sinus surgery.

Encephalomalacia is the softening or loss of brain tissue after cerebral infarction, cerebral ischemia, infection, craniocerebral trauma, or other injury. The term is usually used during gross pathologic inspection to describe blurred cortical margins and decreased consistency of brain tissue after infarction. Multicystic encephalomalacia refers to the formation of multiple cystic cavities of various sizes in the cerebral cortex of neonates and infants after injury, most notably perinatal hypoxic-ischemic events.

A purely intracanalicular cochlear schwannoma presenting with progressive hearing loss.

Schwannomas arising from the cochlear nerve and confined to the internal auditory canal are rare. Clinically, a cochlear schwannoma can cause a progressive hearing loss. We report the case of a 56-year-old woman with a cochlear schwannoma that manifested as a slowly progressive hearing loss.

The effect of lidocaine, bupivacaine and ropivacaine in nasal packs on pain and hemorrhage after septoplasty.

We aimed to investigate the effects of local anesthetics soaked in Merocel nasal packs on hemorrhage and pain after septoplasty. The methodology includes a prospective double-blind study that was conducted in patients undergoing septoplasty because of nasal septal deviation. The study included 143 patients.

Genetic alterations of the LKB1 gene in head and neck cancer.

The genetic alterations associated with head and neck cancer (HNC) are numerous and include a variety of different pathways. It has also been shown that numerous tumor suppressor genes are involved in HNC. The LKB1 gene has been defined as a tumor suppressor gene, and somatic mutations of this gene have been identified in many different neoplasms.

Inflammatory pseudotumor of the lymph nodes in the neck.

Inflammatory pseudotumor is a tumor-like lesion with histopathologic characteristics of inflammation. A 63-year-old woman, who presented with complaints of 2 neck masses on the right side of the neck with waxing and waning course in whom excisional biopsy was performed revealing inflammatory pseudotumor of the lymph node in the neck, is presented, and this rare clinical entity is discussed together with relevant literature.

Schwannoma of the hard palate.

About half of all neurogenic tumors are seen in the head and neck region. The types of neurogenic tumors must be distinguished. Schwannomas originate from Schwann cells of the neural sheath and are solitary, well-encapsulated, slow-growing adjacent to the parental nerve but extrinsic to the nerve fascicles.

Composite cartilage island grafts in type 1 tympanoplasty: audiological and otological outcomes.

Tympanoplasty is a surgical procedure used for eradicating chronic middle ear infection and for reconstructing hearing in infected ears. Independent from the graft placing technique, the atrophy and the insufficiency of the graft material would be seen.For cases at high risk for failure, such as recurrent perforations, total perforations, and severely atelectatic tympanic membranes, many surgeons have used cartilage as a grafting material because of its increased stability and resistance to negative middle ear pressure.

Management of jugular paragangliomas in otolaryngology practice.

Paragangliomas of the head and neck are highly vascular lesions originating from paraganglionic tissue located at the carotid bifurcation (carotid body tumors), along the vagus nerve (vagal paragangliomas), and in the jugular fossa and tympanic cavity and should be considered in the evaluation of all lateral neck masses. The aim of this study was to review an institutional experience in the management of jugular paragangliomas. Thirteen jugular paragangliomas (Fisch classifications C and D glomus jugulare) were treated in our institution during a period of 5 years (2003-2008).

Follicular dendritic cell sarcoma of the parotid gland recurring 6 times within 12 years.

Follicular dendritic cell sarcoma is a rare neoplasm of low to intermediate malignant potential. It can occur in any location where follicular dendritic cells reside, and nearly all the cases reported in clinical notes have occurred as primary lymph node tumors. Carcinosarcoma or true malignant mixed tumor of the salivary gland is a tumor composed of both carcinomatous and sarcomatous elements.

Oropharyngeal flora changes after tonsillectomy.

Objective: We aimed to investigate the effect of tonsillectomy on oropharyngeal flora in children who underwent tonsillectomy for chronic recurrent tonsillitis.

Study Design And Setting: A prospective study was performed comprising patients with chronic recurrent tonsillitis who underwent tonsillectomy at the Department of Otolaryngology, Cerrahpasa Medical School. Incisional core biopsies of excised tonsils were also performed.

Management of paragangliomas in otolaryngology practice: review of a 7-year experience.

Background And Aims: Paragangliomas of the head and neck are highly vascular lesions originating from paraganglionic tissue located at the carotid bifurcation (carotid body tumors), along the vagus nerve (vagal paragangliomas), and in the jugular fossa and tympanic cavity (jugulotympanic paragangliomas) and should be considered in the evaluation of all lateral neck masses. The aim of this study is to review an institutional experience in the management of these tumors.

Materials And Methods: Twenty-six patients with 27 paragangliomas were treated in our institution during a period of 7 years (2000-2007).

Carotid-cavernous fistula after functional endoscopic sinus surgery.

Carotid-cavernous fistulas (CCFs) are anomalous communications between the carotid arterial system and the venous cavernous sinus. They can arise because of spontaneous or trauma causes. Most caroticocavernous fistulas are of spontaneous origin and unknown etiology.

Thermal effects of mobile phones on facial nerves and surrounding soft tissue.

Objective: To investigate the possible thermal effects of microwaves from mobile phones on facial nerves (FN) and surrounding soft tissue.

Study Design: A prospective study.

Methods: We studied FN conduction rate and compound muscle action potentials (CMAP) on 12 rabbits before exposure to radiofrequency radiation (RFR) emitted from a mobile phone.

Detection of HHV-8 and HPV in laryngeal carcinoma.

Objective: In this study we aimed to investigate the presence of human herpesvirus 8 (HHV-8) and human papillomavirus (HPV) in laryngeal carcinoma.

Materials And Methods: Fifty patients operated on because of laryngeal carcinoma were included in the study. Forty-seven had squamous cell carcinoma (SCC) whereas three had verrucous carcinoma.

Unilateral sudden hearing loss as the first sign of chronic myeloid leukemia.

Chronic myeloid leukemia (CML) is one of the etiologic causes of sudden hearing loss and vertigo. However, deafness in association with vestibular symptoms rarely occurs in CML as the first sign. In this article, a 50-year-old male with CML whose first signs and symptoms were unilateral sudden hearing loss and tinnitus in the right ear, vertigo and nausea was presented.
