Olfactory neuroblastoma is a rare malignant tumor of the nasal cavity arising from the olfactory neuroepithelium. It usually presents as a polypoid mass high in the nasal vault including the cribriform plate, superior turbinate, and superior portion of nasal septum. An 89-year-old man visited our office with symptoms of occasional left nasal bleeding and obstruction. On the endoscopic examinations,...
Amyloidosis comprises a diverse collection of disease characterized by the presence of amorphous extracellular eosinophilic deposits of unique protein fibrils that gives apple green birefringence under polarized light after staining with Congo red. Head and neck region is the commonest site for localized form of amyloidosis. We report a case of a 43-year-old man with localized amyloidosis of nasopharynx...
Several articles have demonstrated the efficacy of titanium middle ear prostheses. Our study compares the results of 2 brands of titanium implants that differ in design and weight to assess potential benefit of one over the other. The purpose of this study was to investigate the relationship of prostheses mass based on the stiffness vs mass curve of acoustic transfer between 2 different brands of...
Toxoplasmosis is an ubiquitous protozoan infection, caused by the coccidian Toxoplasma gondii. It usually presents clinically with lymphadenopathy, mainly in the head and neck region. However, in the English literature, very scarce cases of intraparotid Toxoplasma exist, none having been diagnosed preoperatively. In this article, we present 2 cases of intraglandular parotid toxoplasmosis, one diagnosed...
Atresia of the submandibular duct orifice is a rare developmental anomaly. Early identification and treatment of atresia of the submandibular duct orifice prevent feeding and breathing difficulties, dilatation of the submandibular duct, submandibular gland infection, or pressure atrophy. Imperforate submandibular duct should be distinguished from duplication abnormalities of the duct and other cystic...
Otitic hydrocephalus is characterized by elevated intracranial pressure without focal neurologic abnormalities. The pathogenesis of otitic hydrocephalus remains unclear, but it usually occurs secondary to lateral sinus thrombosis. With the advent of new antibiotics, there has been a spectacular decrease in the complications of otitis media. Otogenic intracranial hypertension, always an uncommon condition,...
The pathogenesis of otitis media with effusion (OME) is considered multifactorial, with viral upper respiratory tract infection and eustachian tube dysfunction. Allergy may be related to the pathogenesis of OME or to another etiological factor. We investigated the role of allergic rhinitis (AR) in children with OME and evaluated eustachian tube function in patients with AR.We prospectively analyzed...
The aim of the study was to report the presentation and management of extensive fronto-orbital-ethmoid (FOE) mucoceles.This study is a retrospective chart review of 13 consecutive patients requiring surgical intervention for extensive FOE mucoceles. Patients were treated over the period from 1999 to 2003. Variables examined include chief complaint, risk factors, location of erosion, management, and...
Hydatid cyst in the head and neck is very rare even in countries where echinococcus infestation is endemic. We report the case of a 33-year-old female patient presenting with a hydatid cyst in the lateral cervical region. The diagnosis of hydatid cyst is made mainly with the help of imaging methods and review of the patient's history. Serologic tests can also be useful. The diagnostic use of fine-needle...
The aim of the study was to determine the sensitivity of preoperative positron emission tomography (PET) scans in the detection of primary tumors of the tonsils.We conducted a retrospective review of 46 patients treated at a university medical center for occult tonsillar cancer during the years 2002 to 2004. We identified patients who underwent a preoperative PET scan to locate an unknown primary...
The aberrant internal carotid artery is a rare congenital abnormality that may present with pulsatile hemorrhage if undiagnosed before surgical intervention in the middle ear. We present such a patient who was treated successfully with endovascular sacrifice of one of her bilateral lesions after recurrent episodes of pulsatile hemorrhage complicating multiple tympanostomy tube revisions.
Because of the increasing use of laser surgery for tumors of the upper aerodigestive tract, there is also a discussion in peri- and postoperative complications of this kind of surgery. It was the aim of the present investigation, based on a great number of treated patients, to point out the complications of laser surgery and give a hint for possible dangers.Altogether, 1528 patients suffering from...
This study was conducted to investigate whether there is any difference between tonsillar surface and deep tissue cultures in patients who underwent tonsillectomy for recurrent tonsillitis.Tonsillar surface and core tonsillar cultures were taken in all patients. The samples were inoculated into 5% sheep blood, chocolate, and MacConkey agar. The bacteria isolated were identified by using standard methods...
A case of a foreign body lodged in the nasopharynx for a long time as a complication of adenotonsillectomy is presented. The patient was an 11-year-old boy admitted with nasal obstruction and bilateral foul-smelling purulent rhinorrhea. The diagnosis was confirmed with nasal endoscopy. Immediate removal of foreign body in the nasopharynx was performed under general anesthesia. Although foreign bodies...
Congenital immature teratoma of the nasopharynx is a very rare form of extragonadal teratoma. In this article, management of a newborn with nasopharyngeal teratoma who underwent tumor resection is reported. The tumor, which originated from the nasopharynx, almost filled the oral cavity and protruded through the mouth, with its external part comparable to the size of the head. She could breath when...
Collision tumors are rare entities wherein 2 separate, distinct histologic malignant neoplasms occur in adjacent anatomic proximity. The 2 malignancies may originate from the same organ or occur as metastases from other sites. We present a case of a collision tumor of metastatic lung adenocarcinoma and papillary thyroid carcinoma occurring in the thyroid gland of a 63-year-old woman who presented...
