David T Kent, David H Chi, Dennis J Kitsko
The purposes of this study were to determine if use of a powered drill or trainee involvement during tympanoplasty is associated with a decline in sensorineural hearing, as well as to examine whether trainee involvement affected tympanic membrane (TM) closure rates. This study was a chart review (February 2006 to October 2011) of 172 pediatric otolaryngology patients undergoing type I tympanoplasty for TM perforation of any etiology at a tertiary-care pediatric otolaryngology practice. Data collected included air conduction (AC) at 250 to 8,000 Hz, speech reception thresholds, bone conduction (BC) at 500 to 4,000 Hz, and air-bone gap (ABG) at 500 to 4,000 Hz...

INTRODUCTION: Surgical repair of the tympanic membrane, termed a type one tympanoplasty is a tried and tested treatment modality. Overlay or underlay technique of tympanoplasty is common. Sandwich Tympanoplasty is the combined overlay and underlay grafting of tympanic membrane. OBJECTIVE: To describe and evaluate the modified sandwich graft (mediolateral double layer graft) tympanoplasty using temporalis fascia and areolar fascia. To compare the clinical and audiological outcome of modified sandwich tympanoplasty with underlay tympanoplasty...

Objective: To discuss the prediction of round window(RW) visibility in cochlear implantation(CI) with temporal bone high resolution computed tomography(HRCT). Methods: From January 2013 to January 2017, 130 cases underwent both HRCT and CI in our hospital were analyzed. The distance from facial nerve to posterior canal wall(FWD), the angle between facial nerve and inner margin of round window(FRA), and the angle between facial nerve and tympanic anulus to inner margin of round window(FRAA) were detected at the level of round window on axial temporal bone HRCT...

OBJECTIVE: Removing the posterior canal wall or canal wall down mastoidectomy (CWDM) for the management of cholesteatoma remains controversial. We advocate partial removal of the posterior canal wall for complete eradication, followed by canal wall defect reconstruction to restore the normal anatomy and avoid the complications of CWDM. MATERIALS AND METHODS: Sixty-four patients with cholesteatoma (71 ears) were included. This study was conducted between 2009 and 2012...

The ability of Spatially Offset Raman Spectroscopy (SORS) to obtain chemically specific information from below the sample surface makes it a promising technique for non-invasive in vivo diagnosis of bone conditions by sampling bone through the skin. The depth below a surface interrogated by SORS depends on the system's optical properties and is difficult to estimate for complex bone material. This paper uses 830 nm laser excitation to investigate the influence of bone mineralization on photon migration properties in deer antler cortex, equine metacarpal cortex and whale tympanic bulla...

BACKGROUND AND PURPOSE: Cross-sectional imaging of the temporal bone is challenging because of the complexity and small dimensions of the anatomic structures. We evaluated the role of flat panel angiography in the cross-sectional imaging of the temporal bone by comparing its image quality and radiation dose with a 64-section multisection CT scanner. MATERIALS AND METHODS: We retrospectively collected 29 multisection CT and 29 flat panel angiography images of normal whole-head temporal bones...

OBJECTIVE: Since the 1950s, microscopic myringoplasty has been the standard surgery for repairing a perforated tympanic membrane. In addition to conventional microscopic myringoplasty, endoscopic myringoplasty has been an emerging technique since the late 1990s. This study evaluated the efficacy of endoscopic transcanal myringoplasty for repairing tympanic perforations and examined the minimally invasive feature of this technique (no postauricular incision, no canalplasty). METHODS: We retrospectively reviewed the medical records of patients who underwent endoscopic transcanal myringoplasty for perforations of the tympanic membrane...

BACKGROUND: Chondroblastoma commonly involves the temporal bone in the craniofacial region, but its imaging features have not been elucidated. This study aimed to describe the imaging features of temporal bone chondroblastoma with their pathologic correlation. METHODS: Radiopathologic correlation was performed in 5 patients with temporal bone chondroblastoma from our database and in 11 patients identified through a PubMed search. RESULTS: The cases of temporal bone chondroblastoma commonly involve the squamous part, temporal and infratemporal fossae, temporomandibular joint, and tympanic cavity, with the following features: high attenuation with calcification; heterogeneity; low signal intensity on T2-weighted imaging with enhancement; a smooth interface to the brain; and strong hypermetabolism on fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT...

Real-time detection of basic physiological parameters such as blood pressure and heart rate is an important target in wearable smart devices for healthcare. Among these, the core body temperature is one of the most important basic medical indicators of fever, insomnia, fatigue, metabolic functionality, and depression. However, traditional wearable temperature sensors are based upon the measurement of skin temperature, which can vary dramatically from the true core body temperature. Here, we demonstrate a three-dimensional (3D) printed wearable "earable" smart device that is designed to be worn on the ear to track core body temperature from the tympanic membrane (i...

The objective is to increase awareness of facial nerve schwannomas (FNSs). Clinical data from 32 cases with FNSs who received surgical treatment from 2005 to 2015 were reviewed retrospectively. The clinical data included age, sex, presentations, duration, facial nerve function, temporal-bone high-resolution computed tomography (CT) and magnetic resonance imaging (MRI) findings, surgical approaches, and postoperative histopathological examination. 16 men and 16 women were included, aged 7-69 years. The average age at diagnosis was approximately 44 years...

OBJECTIVE: To study age-related changes in the morphology of the supratubal recess (STR) and its relationship with the Eustachian tube (ET). METHODS: Seventy randomly selected computed tomography (CT) images of non-pathological temporal bones of 49 patients were reviewed retrospectively. The patients were grouped according to age into 4 age groups: group A (0-3 years), group B (4-8 years), group C (9-18 years) and group D (19-50 years). Space analytic geometry was assessed to directly calculate the morphology of the STR and the ET...

INTRODUCTION: Stimulation of the cochlear round window (RW) with the floating mass transducer (FMT) still suffers from large variation in clinical outcomes. Beside the geometric mismatch between RW and FMT diameter that is a known limiting factor in achieving optimal coupling between actuator and RW membrane, the applied static force between FMT and RW is usually undefined. In this study, the feasibility and efficacy of a specially designed FMT coupler permitting application of static preloads to the RW membrane to optimize FMT-RW coupling was investigated...

Blast overpressure causes dynamic damage to middle ear components, and tympanic membrane (TM) rupture is the most frequent middle ear injury. However, it is unclear how the blast waves change mechanical properties of the TM and affect sound transmission through the ear. This paper reports the current study on dynamic properties of the TM after exposure to blast waves by using acoustic loading and laser Doppler vibrometry (LDV). The TM specimens were prepared from human temporal bones following exposures to blast overpressure...

The mode of the introduction of the active electrode of a cochlear implant into the cochlea remains a key issue as far as cochlear implantation is concerned. Especially much attention has recently been given to the relationship between the anatomical features of the basal region of the cochlea (the so-called 'fish hook') and the possibility to approach it. We have undertaken the attempt to optimize the approach to the tympanic canal (scala tympanica) of the cochlea with a view to reducing to a minimum the risk of an injury to the cochlear structures in the course of cochlear implantation...
