In total, 83 patients who underwent intact canal tympanoplasty with mastoidectomy between 2010 and 2015 were included and divided into two different groups: malleus assembly to the stapes head (MASH) and tympanic membrane assembly to the stapes head (TASH).

An Unusual Presentation of Gout: Tophi in the Middle Ear.

Gout is a common metabolic disease and is characterized by episodic acute and chronic arthritis caused by the deposition of monosodium urate (MSU) crystals in joints and connective tissues. The most commonly involved joint is the first metatarsophalangeal joint. It may also present with nonspecific complaints caused by gouty tophi in unusual sites of the body such as the spine, bone, and middle ear.

Two Different Percutaneous Bone-Anchored Hearing Aid Abutment Systems: Comparative Clinical Study.

Comparing audiological test results obtained from a sound processor attached to a Softband with direct and magnetic passive bone conduction hearing implant systems.

The aim of this study was to compare audiological test results obtained from a sound processor (SP) attached to a Softband with those obtained from direct (abutment connection) bone conduction implant systems and magnetic passive bone conduction implant systems with different magnet strengths on patients implanted at our clinic. Twenty-four patients who were implanted with either an abutment or magnetic bone conduction implant system between January 2012 and December 2014 were analyzed for hearing results, such as free-field hearing thresholds, direct bone conduction hearing thresholds, and speech discrimination scores with aided and unaided conditions Both magnetic and direct osseointegrated bone conduction implant systems, as well as the Softband system, provide good hearing outcomes when compared with unaided performance; however, the abutment connection system gives better hearing thresholds in the higher frequencies. No significant difference in hearing gain was found between the Softband system, magnet 5, and magnet used by the patient.

Intramuscular hemangiomas of the head and neck: Three case reports.

Hemangiomas are tumors of vascular origin that frequently occur on the skin and mucosal surfaces in the pediatric age group. Hemangiomas located in skeletal muscles are called intramuscular hemangiomas. Intramuscular hemangiomas mostly occur in the extremities and the trunk.

Possible protective effect of sertraline against cisplatin-induced ototoxicity: an experimental study.

Background/objective: Cisplatin is a widely used chemotherapeutic agent, but its ototoxicity side effect can occur in the majority of patients. Lots of agents were tried to prevent this, but there is not a routine treatment modality yet. The aim of this study was to evaluate the otoprotective effect of sertraline, which is an antidepressant with neuroprotective effects, against cisplatin, in rats.
