Three week loading for the Baha BI-300® implant system.

Purpose: The timing of loading of titanium craniofacial implants is dependent upon implant characteristics, host factors, and the bonding of titanium oxide and bone referred to as osseointegration. The purpose of this feasibility study seeks to determine the safety of early loading of the Baha BI-300 implant system (Cochlear Limited, Englewood, CO), which has been modified with novel surface texture and geometric design.

Subjects And Methods: This prospective study measures implant stability as determined by clinical evaluation and resonance frequency analysis at implantation and at 1, 3, 6, 12, 24 and 52weeks post-op in 20 patients who underwent single-stage implantation and exteriorization of the BI-300.

Subfreezing versus room-temperature balloon dilation of benign tracheal stenosis: a pilot study in rabbits.

We conducted an experiment to compare collagen deposition in tracheal stenoses dilated with room-temperature balloons and stenoses dilated with balloons at a subfreezing temperature (-10°C). Six New Zealand white rabbits underwent endoscopic tracheal injury. Tracheal dilation was performed at 3 weeks postinjury with either a room-temperature balloon or a vascular cryoplasty balloon.

A prospective study to evaluate the efficacy of isopropyl alcohol irrigations to prevent cerumen impaction.

We conducted a prospective crossover study to assess the safety and efficacy of 70% isopropyl alcohol delivered from a squeezable bottle with a specially designed tip as a weekly irrigant to reduce cerumen accumulation. Twenty patients were divided into 2 groups of 10 (20 ears in each group). The patients in group 1 instilled 70% isopropyl alcohol once a week for 2 months; this was followed by 2 months of no ear cleaning.

Early posttreatment audiometry underestimates hearing recovery after intratympanic steroid treatment of sudden sensorineural hearing loss.

Objective. To review our experience with intratympanic steroids (ITSs) for the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL), emphasizing the ideal time to perform follow-up audiograms. Methods.

Mixed hearing loss in iatrogenic tympanic membrane perforations over the round window niche and the immediate effect of paper patch myringoplasty.

Objectives: Report the immediate audiologic effect of paper patch myringoplasty to repair iatrogenic tympanic membrane perforations directly over the round window.

Methods: Retrospective case-control study of 15 patients treated for inner ear disease with a MicroWick and dexamethasone for 1 month, resulting in 2-mm perforations over the round window. Paper patch myringoplasties were performed to repair the perforations.

Complications of bone-anchored hearing devices.

Complications of bone-anchored hearing devices occur with both soft tissue and bone. Soft tissue complications are much more common and most often involve irritation of the skin surrounding the implant. Other complications include: skin flap necrosis, wound dehiscence, bleeding or hematoma formation, and persistent pain.

Induction of tracheal stenosis in a rabbit model-endoscopic versus open technique.

Objective: To evaluate and compare open versus endoscopic methods of inducing tracheal stenosis in the New Zealand white rabbit model.

Study Design: Prospective randomized control, pilot study.

Subjects And Methods: Fifteen New Zealand white rabbits were used in the study.

Computed tomography and otosclerosis: a practical method to correlate the sites affected to hearing loss.

Objectives: We present a practical method for correlating computed tomography (CT) scans with hearing loss in otosclerosis.

Methods: We reviewed the CT scans of 18 patients (34 ears) with clinical otosclerosis who were seen between 2007 and 2008. The scans were reviewed by an otologist in a clinical office setting, followed by a blinded radiologist working at an imaging workstation.

Initial clinical experience with balloon dilation in revision frontal sinus surgery.

Objectives: The purpose of this study was to determine whether balloon dilation is effective in revision frontal sinus surgery.

Methods: We retrospectively reviewed all patients who had previously undergone endoscopic frontal sinus surgery and had persistent sinusitis. All patients then underwent balloon dilation of the frontal ostium.

High dietary intake of sodium selenite induces oxidative DNA damage in rat liver.

One mechanism for the cancer-chemopreventive effects of high selenium (Se) intake is hypothesized to be antioxidant protection of DNA. In this work we examine DNA oxidation in whole animals as a function of dietary Se intake and carcinogen administration. Weanling male Sprague-Dawley rats were fed a basal, Torula yeast-based, Se-deficient diet supplemented with 0, 0.
