Ossicular reconstruction for incus long-process defects: bone cement or partial ossicular replacement prosthesis.

Objective: The objective of this study was to compare hearing results in patients undergoing ossiculoplasty with bone cement (BC) vs partial ossicular replacement prosthesis (PORP) in cases of incudostapedial discontinuity during tympanoplasty surgeries.

Study Design: Case series with chart review.

Setting: Tertiary referral center.

Endoscopic endonasal management of cerebrospinal fluid rhinorrhea.

The authors review their 5 years' experience with endonasal endoscopic repair of the anterior skull base fistulas presenting with cerebrospinal fluid (CSF) rhinorrhea. A total of 12 patients were managed endoscopically between 2004 and 2008. Seven patients (58.

Protective role of resveratrol against cisplatin induced ototoxicity in guinea pigs.

Objective: The aim of this study was to evaluate the effectiveness of systemic administration of resveratrol against cisplatin-induced ototoxicity in guinea pigs.

Materials And Methods: Healthy guinea pigs (n=24) were randomly divided into four groups. Group 1 (n=6) received resveratrol+cisplatin, group 2 (n=6) received 4% ethanol+cisplatin, group 3 (n=6) received cisplatin, and group 4 (n=6) received saline.

Pleomorphic adenomas recurrences within the parapharyngeal space.

This study was undertaken to evaluate and concentrate on the recurrent pleomorphic adenomas (PAs) of the parapharyngeal space. The records of 9 patients treated for recurrent PAs occupying parapharyngeal space were retrospectively reviewed. The study population comprised 6 women and 3 men with a mean age of 51 (range, 35-79 years).

Histologic changes in eustachian tube mucosa of rats after exposure to gastric reflux.

Objective: Reflux is thought to be a risk factor for middle ear disease, but the mechanism underlying this relationship is unclear. In this study, we evaluated the effects of reflux on the eustachian tube (ET) mucosa.

Materials And Methods: Twenty-two healthy 150 to 220 g Wistar rats with normal middle ears were used.

Primary malignant melanoma of the middle ear mucosa: a case report.

Primary involvement of the middle ear and mastoid mucosa by malignant melanoma (MM) has been rarely reported. We report an 81-year-old Caucasian woman presenting with otalgia, left-sided aural fullness, and hearing loss. Otoscopic examination revealed a purple-colored polyp that appeared to be vascular, occupy left external auditory canal (EAC).

Vitamin e-coated tympanostomy tube insertion decreases the quantity of free radicals in tympanic membrane.

Objective: Tympanosclerosis is a common sequela of ventilation tube treatment of otitis media with effusion causing hearing disability. It is associated with an increased production of free radicals (also known as reactive oxygen species) after myringotomy. Vitamin E is a scavenger of different free radicals by working as an antioxidant.

Effects of vitamin E on cigarette smoke induced oxidative damage in larynx and lung.

Objectives: Cigarette smoke (CS) contains a large variety of compounds, including many oxidants and free radicals (also known as reactive oxygen species), that are capable of initiating or promoting oxidative damage, which leads to various degenerative pulmonary and cardiovascular diseases as well as cancer. Recent studies have established a strong relationship between CS and development of reactive oxygen species (ROS). The aim of the present study was to detect ROS levels in laryngeal and lung tissues of rats by measuring luminol-amplified chemiluminescence and to determine the changes in ROS levels in lung and laryngeal tissues induced by exposure to CS, with and without concurrent treatment with vitamin E.

The effect of Vitamin E treatment on the development of myringosclerosis after ventilation tube insertion.

Objectives: Recent studies have established the relationship between the reactive oxygen species and myringosclerosis. Furthermore several antioxidants have been known to prevent myringosclerosis. All the previous studies supporting this hypothesis have been performed on animals.

Determination of reactive oxygen species in myringotomized tympanic membranes: effect of vitamin e treatment.

Objectives/hypothesis: Recent studies have established a strong relationship between the development of myringosclerosis and reactive oxygen species (ROS). The aims of the present study were to directly detect ROS in the tympanic membrane and middle ear mucosa of rats by measuring luminol amplified chemiluminescence, to evaluate the changes in the levels of ROS after treatment with vitamin E, and to examine the possible changes in the tympanic membranes otomicroscopically and histologically.

Study Design: Prospective controlled animal study.

Reflux of nasopharyngeal content into middle ear through the eustachian tube.

Whether nasopharyngeal content passes into the middle ear in patients without any head and neck pathology during the recovery phase of anesthesia is shown with an objective and prospective method. Thirty-eight patients, 21 female and 17 male, aged between 17 and 76, were included in the study. During the recovery phase of general anesthesia, 10 ml of 5 mCi Tc-99m-MAA was administered intranasally to the patients with a 10-F catheter.
