This study was designed to evaluate the clinical usefulness of 3-dimensional computed tomography (CT) laryngography for the determination of subglottic extension in laryngeal cancer and for the involvement of the pyriform sinus apex in hypopharyngeal cancer. Twenty-one patients with laryngeal cancer and 19 patients with hypopharyngeal cancer underwent spiral CT during quiet breathing, /E/ phonation,...
Massive hemorrhage is an unusual complication of tracheotomy, and the most common causes are injury to the anterior jugular veins and the thyroid isthmus, or unrecognized variations of the vascular structures, such as the arteria thyroidea ima. We present a case of high-running innominate artery that ascends until the third tracheal ring and courses horizontally anterior to the trachea in a patient...
Carotid body tumors constitute the third commonest group of parapharyngeal tumors. Newer diagnostic modalities such as computed tomography scan, magnetic resonance imaging, and Doppler ultrasound are commonly used for diagnosing lesions at this site. However, simple technique of fine-needle aspiration (FNA) cytology is rarely performed in apprehension of complication of hemorrhage. Present case report...
The diagnosis of atypical cervicofacial lymphadenitis is often not readily clinically apparent. Parents may bring a child to the physician's attention long before the development of the classic findings. When assessing the child with acute-onset cervicofacial lymphadenitis, there are 2 imperative clinical determinations: Is the lymphadenitis of viral, bacterial, or mycobacterial etiology? If of mycobacterial...
We report a case of capillary hemangioma of the tympanic membrane in a 51-year-old man with conductive hearing loss, otalgia, and otorrhea. On examination, the external auditory canal was obstructed with a hard, dark red tumor, and purulent discharge was observed. The infection was controlled with antibiotics, but hearing loss persisted. Therefore, transcanal resection was performed. The tumor was...
Primary lymphoma of the lacrimal drainage system (LDS) is an extremely rare condition. All of those previously reported have been of B-cell origin, with the exception of 1 case report of a natural killer/T–cell lymphoma in a Japanese woman. We report a 41-year-old Chinese woman who had a primary diffuse large B-cell non-Hodgkin lymphoma of left LDS. After 8 cycles of CHOP (cyclophosphamide [Cytoxan],...
Standard CD44 (CD44st), CD44 variant 5 (CD44v5), and CD44 variant 6 (CD44v6), intercellular adhesion molecule 1(ICAM-1), and vascular cell adhesion molecule 1(VCAM-1) are expressed in human malignant cells and tissues. Their mechanism remains unclear but has been reported to be associated with the progression and metastasis of malignancies.In this study, we investigated any correlations between the...
To compare Ki-67 expression patterns in middle ear cholesteatoma with the corresponding retroauricular and external auditory canal skins, and to determine the cell cycle–dependent localization of Ki-67.MIB-1 monoclonal antibody was used for comparative assessment of proliferative activity of middle ear cholesteatoma, external auditory canal skin, and retroauricular skin samples on formalin-fixed paraffin-embedded...
Merkel cell carcinoma is a rare malignant tumor of the skin. The face and extremities are the most common locations. We present a case of Merkel cell carcinoma of the auricle in a 93-year-old man subsequently treated with surgery and radiotherapy. The clinical features, prognosis, and treatment of the Merkel cell carcinoma are discussed.
Cutaneous mucormycosis in the immunocompetent patient is exceedingly rare. However, if the infection is not rapidly identified and aggressively treated, its progression is fast, fulminate, and characteristically fatal. This case report describes the treatment and surgical reconstruction of a previously healthy, immunocompetent girl after pervasive mucormycosis of the right face. The patient's diagnosis...
The purpose of this paper is to describe the outcome of biofeedback training of nasal muscles in cases of nasal valve stenosis and collapse. The present study was performed to investigate the best way of using surface electromyography (sEMG) in biofeedback training of muscles involved in nasal valve function. In the present study, we present the way of biofeedback training of these muscles introducing...
Sleep apnea is well known as a primary medical condition at this time. However, life-threatening diseases in which sleep apnea is the presenting symptom are less well described. The case of a 71-year-old man with a frontal lobe glioblastoma whose primary presenting symptom was sleep apnea is discussed. The relationship of intracranial tumors to sleep apnea symptoms is reviewed.
This patient presented with a neck mass diagnosed as a papillary thyroid carcinoma by fine-needle aspiration. Preoperative computed tomography revealed a papillary carcinoma within a juxtathyroidal thyroglossal duct cyst. After surgery, the initial diagnosis was papillary thyroid carcinoma. After correlation with the computed tomography, the diagnosis was revised to a papillary thyroid carcinoma plus...
Traumatic amputation of the nose is a challenging management problem. We describe the case of a 69-year-old woman who had a dog-bite nasal amputation. The avulsed piece, including the lobule, and approximately half of the columella and alae, was replanted within 2 hours of the trauma. Hyperbaric oxygen therapy was administered for 12 daily sessions. Skin gradually necrosed, and the eschar was tangentially...
To present a technique for the treatment of complete esophageal stenosis in the post-radiation patient that may be applied to selected patients with obstructing stenoses.A case report of the treatment of a post-radiation esophageal web.A review of the patient's history of treatment and a discussion of reported treatment options.A complete obstruction of the cervical esophagus was diagnosed in a patient...
