One of the most striking qualities of cancer is its spread throughout the body. The location of a metastatic mass may help to identify the primary tumor. Metastases to head and neck area can occur either from local structures or from distant organs.This study was a retrospective review of patients from a University Hospital in Tehran, Iran, during the period 1992 to 2008. The data were analyzed for...
Biofilms play a role in the pathogenesis of a variety of otorhinolaryngologic diseases, including otitis media and cholesteatoma. Despite this, relatively few studies have undertaken to demonstrate the presence of biofilms tissues from patients with chronic otitis media or infected cholesteatoma.Our objective is to detect evidence of biofilms human chronic ear infections with scanning electron microscopy...
The isolated malleus-handle fracture is a rare ossicular injury and tends to be overlooked when the tympanic membrane appears normal. Various surgical attempts have been made to correct this fracture; however, these techniques largely relied on xenograft implantation materials; the autologous cartilaginous graft application has never been reported. Herein we describe a simple, rapid, and effective...
Subperiosteal orbital abscesses (SPOAs) secondary to acute sinusitis are rare occurrences in the pediatric age group, more so in the neonatal period. Here, a rare case of SPOA in a 38-day-old newborn later drained via endoscopic sinus surgery is included also. This review describes the demographic data, clinical history, treatment, microbiology results, complications, and outcome.The admission records...
Cochlear implants are used worldwide for the treatment of severe to profound bilateral sensorineural hearing loss in both adults and children. A number of implantees are likely to be treated with radiosurgery later in life, but very little is known about the effects of radiosurgery on cochlear implants. We report a cochlear-implanted patient who underwent radiosurgery due to a recurrent meningioma...
The parapharyngeal space is a complex and well-defined anatomical zone lying lateral to the pharynx and medial to the ramus of the mandible. Although tumors of this space are rare, the parapharyngeal space is difficult to examine clinically; and diagnostic modalities of computerized tomographic scanning and magnetic resonance imaging are primarily used in the evaluation of parapharyngeal space lesions...
To study whether adenovirus-mediated human β-nerve growth factor (Ad-hNGFβ) gene has any protective effect on rat cochlear spiral ganglion after blast exposure.Deafness was induced by blast exposure (172.0 dB) in 20 healthy rats. Seven days after blast exposure, Ad-hNGFβ was infused into the perilymphatic space of 10 animals as the hNGFβ/blast group, and artificial perilymph fluid (APF) was infused...
The auricle is a frequently injured part of the head and neck during thermal injury leading to ear deformity. The burned ear represents one of the most difficult problems for reconstructive surgeons. Mafenide acetate is a topical agent used routinely for these patients, but it has some disadvantages including painful application and allergic rash. Some authors have reported the healing effect and...
Surgical removal of a thyroglossal duct cyst (TGDC) and its tract is usually accomplished through an external neck incision, including the removal of the middle part of hyoid bone and a block of tissues extending to the foramen cecum. However, this procedure inevitably results in neck scarring. We implemented a modified approach to TGDC removal in a 28-year-old woman through the floor of the mouth...
Salivary stones larger than 15 mm are classified as giant sialoliths. They are uncommon in the practice of otolaryngology, and their management has always been a therapeutic challenge. Traditionally, when they cannot be retrieved by marsupialization, removal of the salivary gland has been advocated. Sialendoscopy and the recent development of combined endoscopic and external approaches for extraction...
Osteochondromas are the most common benign bone tumor, most commonly found in the ends of long bones; however, they rarely involve facial bones, particularly the mandible. Osteochondromas involving the coronoid process have rarely been reported in the literature but pose a diagnostic dilemma. When large enough, osteochondromas of the mandibular coronoid process can form a joint with the zygomatic...
Most migrated foreign bodies in the neck were removed immediately in patients with persistent symptoms. It is a rare condition that a fish bone was buried for a prolonged time in the tongue with little discomfort. We report a unique case of an ingested fish bone lodged in the tongue for 16 months until infection ensued. Ludwig angina was considered first because the patient had fever, odynophagia,...
An asymmetric smile, caused by loss of function of the lip depressors, can be functionally and cosmetically debilitating. Although some surgeons report excellent results with muscle transfer to the lower lip, many facial reanimation surgeons find that dynamic techniques do not consistently address the lower lip. Our objectives were to retrospectively review our outcomes after treatment of the asymmetric...
Although auditory disorders are complex conditions, device-related modalities dominate current treatment. However, dysfunction from the central cortex to the inner ear apparatus is increasingly thought to be related to biochemical pathway abnormalities and to free radical–induced oxidative damage and chronic inflammation. Therefore, considering appropriate biologic therapy as an adjunct to standard...
