JOURNAL FREE ACCESSWe retrospectively analyzed 12 patients with blood boils of the maxillary sinus treated from May 2000 to July 2004. Subjects were 8 men and 4 women aged 15 to 56 years (mean : 30.8 years). In 11, we conducted endoscopic sinus surgery to extirpate the tumorous mass. In 2, we removed it with little blood loss after selective embolization of the feeding arteries. Endo-scopic sinus surgery and selective embolization are thus effective in extirpating blood boils of the maxillary sinus. We also review the pertinent literature.View full abstractDownload PDF (5676K) -

JOURNAL FREE ACCESSNeurilemmoma arising from the brachial plexus manifests itself as a tumor mass in the supraclavicular fossa where the brachial plexus exists anatomically. It may be accompanied by pain radiating to the upper limb, tenderness, and neurogenic symptoms such as a feeling of numbness. Neurilemmoma should be considered as a differential preoperative diagnosis because nerve deficiency symptoms develop with tumor removal. A 49-year-old man with a tumor on the left side of the neck was not found in preoperative CT, MRI, gallium scintigraphy, or aspiration cytology to have a definitive diagnosis. Intraoperative findings and rapid pathological examination led to a diagnosis of neurilemmoma. The tumor was removed intercapsularly with a nerve-stimulating device under a microscope while taking care to avoid damaging the nerve. Left upper limb numbness remaining postoperatively improved in 3 months and results were satisfactory overall.View full abstractDownload PDF (3784K) -

JOURNAL FREE ACCESSDermoid cysts of the mouth floor are relatively rare. We report a case of a giant dermoid cyst arising in the floor of the mouth of a 17-year-old man, who noticed its rapid growth. He reported dysarthria and feeding disturbance. The tumor was located in the month floor midline and its content was not transparent. MRI showed a low Ti and high T2 cystic lesion 45×35×30mm in the mouth floor. Fine-needle aspiration removed viscous matter, including squamous epithelium, diagnosed as class I. These findings were useful in preoperative by diagnosing this dermoid cyst. Under general anesthesia, the cyst was surgically removed in an intraoral approach. When we exfoliated the bottom of the cyst, we made a small hole at the top of the cyst and squeezed out part of the content due to the blopcked field of vision in surgery. Histopathologicaly, the cyst wall was lined with stratified squamous epithelium and included sebaceous glands. Since the cyst contained skin appendages, it was diagnosed as dermoid.View full abstractDownload PDF (2752K) -

JOURNAL FREE ACCESSBack ground : We evaluated the fit of adjusting hearing aids to ears using the acoustic phenomena.
Method : We used acoustic phenomena to adjust hearing aids, then modified speech audiometry with speaker method suitable to older patients, and measured the discrimination between uncorrected ears and ears with hearing aids.
Results : Discrimination reflected the insertion gain in hearing aids and was represented as a discrimination score. This showed the effect of hearing aid insertion gain.
Conclusion : Our proposed method of fit related to speech audiometry can measure ears with hearing aids simultaneously.View full abstractDownload PDF (6644K) -

JOURNAL FREE ACCESSOptic nerve disorder due to diseases of paranasal sinuses has an incidence of 2-5% in diseases of the paranasal sinuses. with the incidence highest in posterior paranasal sinus cyst. Posterior paranasal sinuses are anatomically close to the optic nerve, oculomotor nerve, trochlear nerve, abducent nerve, internal carotid artery and cavernous sinus, with symptoms caused by cyst inflammation and pressure. These symptoms belong to the domains of ophthalmology, neurosurgery, and internal medicine, not of otorhinolaryngology, so many patients visit ophthalmology, neurosurgery and internal medicine departments for their first medical examination.
In nasal optic nerve diseases, early discovery and treatment are thought to greatly influence prognosis. Eye doctors, neurosurgeons, and internists find it difficult to judge that paranasal diseases are accountable for nasal optic nerve diseases, which leads to delays in starting treatment. A 51-year-old woman seen at internal medicine first for headache and, later, vision disturbance, blerharoptosis, and ocular motor apraxia, was sent to ophthalmology and neurosurgery, whereupon a sphenoidal sinus cyst was found in imaging and she was referred to otorhinolaryngology. Intranasal surgery for the paranasal sinus and steroid preparations improved blepharoptosis and ocular motor apraxia, but the vision disturbance remained.View full abstractDownload PDF (5707K) -

JOURNAL FREE ACCESSOsteomas, benign bone-forming tumors, commonly originate in the paranasal sinuses in the head and neck. In the temporal bone, exostosis of the external auditory canal is common but mastoid osteomas are rare.
We present two cases of osteoma of the external auditory canal and one of the mastoid bone. Surgical removal and pathological study confirmed the diagnosis. We also discuss differences and surgical therapies in exostosis and osteoma.View full abstractDownload PDF (5044K) -
