Inhibitory effect of N-acetyl cysteine and ascorbic acid on the development of myringosclerosis: an experimental study.

Objectives: This study investigated the effects of ascorbic acid and N-acetyl cysteine (NAC) antioxidants on the development of myringosclerosis (MS) in an experimental model.

Methods: Myringotomies were performed in the ears of 15 guinea pigs, and Spongostan pieces were placed on the perforated regions of the tympanic membrane. The subjects were divided randomly into three groups and treated with three different solutions on the Spongostan-group 1: (control, 0.

Hearing loss effects of administering boric alcohol solution prepared with alcohol in various degrees on guinea pigs (an experimental study).

Objective: To investigate the ototoxic effect of boric acid solution prepared with different degree of alcohol.

Methods: This study was performed on 28 young albino guinea pigs. After the animals divided four groups prior to the application of the solution an auditory brainstem response (ABR) test was applied to the each animal under general anesthesia.

New technique for the treatment of bilateral vocal cord paralysis: Vocal and ventricular fold lateralization using crossing sutures with thyroplasty technique.

Conclusion: All patients treated with this new lateralization technique had a good quality of life and no dyspnea at rest or upon exertion. We believe that this technique is an important addition to the many surgical techniques for the treatment of bilateral vocal cord paralysis (BVCP).

Objectives: Most techniques used in the treatment of BVCP result in a prolapse of the laryngeal soft tissues into the endolarynx owing to Bernoulli's principle.

[Stomal recurrence after total laryngectomy: clinical and patological analysis of risk factors].

Objectives: The aim of this study is to evaluate risk factors for stomal recurrence and to state and emphasize the importance of these factors.

Patients And Methods: This study was carried out retrospectively on 119 patients (116 males, 3 females; mean age 56.8 years; range 31 to 86 years) with larynx cancer who underwent total laryngectomy.

Tympanosclerosis and our surgical results.

Tympanosclerosis is a sequel of chronic otitis media characterized by the deposition of calcareous plaques following hyaline degeneration in the fibrous layer of the tympanic membrane and inside middle ear mucosa. It usually results from prior middle ear infections. In this study, results of treatment and clinical findings of the patients with tympanosclerosis are presented.

Outcome of conservation surgery for laryngeal carcinoma: an 8-year trial.

The purpose of this report is to review the experience of our institution with conservative surgery for laryngeal cancer. In this retrospective study, a review was made of 85 patients treated with conservation surgery between 1998 and 2005. At least 2 years of follow-up period (mean 46.

The ototoxic effect of boric acid solutions applied into the middle ear of guinea pigs.

This study analyzed the ototoxic effects of boric acid solutions. Boric acid solutions have been used as otologic preparations for many years. Boric acid is commonly found in solutions prepared with alcohol or distilled water but can also be found in a powder form.
