Preoperative Voice Characteristics in Thyroid Patients.

Introduction: Thyroid surgery outcomes have evolved from mortality control strategies to morbidity control measures. Most vocal outcomes research in thyroid surgery are focused on recurrent nerve anatomic and functional preservation. However, there are likely multiple causes of vocal dysfunction in thyroid patients.

Effect of Water Precautions on Otorrhea Incidence after Pediatric Tympanostomy Tube: Randomized Controlled Trial Evidence.

Objectives: Tympanostomy with ventilation tube insertion is the most common otologic surgery. Many surgeons recommend water precautions, although its utility is questioned. We aimed to investigate if water precautions reduce the rate of otorrhea after transtympanic tube insertion.

Including auditory tube function on models is relevant to assess water exposure after tympanostomy tubes-Multiphase computerized fluid dynamics model.

Introduction: Myringotomy with tympanostomy tube is the most common otologic surgery and some patients are still advised to avoid water. However, there is no evidence supporting this, with published papers questioning the need for this advice.

Methods: A Multiphase Computational Fluid Dynamics (CFD) model was created using computerized tomography images of a child's healthy ear.

Structure of the rat tracheal mucosa after chronic intermittent hypoxia or chronic hyperbaric oxygen therapy.

Objective: This paper is aimed at identifying putative morphological changes induced in the rat's tracheal mucosa by chronic hyperbaric oxygen (HBO) treatment or chronic intermittent hypoxia (CIH).

Study Design: Tracheal samples were obtained from three groups of 11, 12 and 13 adult Wistar rats. The first group was submitted to 20 sessions of 100 min-long HBO treatment; the second group was submitted to eucapnic CIH for 35 days; and the third group was not submitted to any CIH or HBO therapy.

[Informed Treatment Consent and Refusal in Advanced Endonasal Surgery: The Ethical Dilemma of Olfaction Sacrifice in Surgery for Chronic Rhinosinusitis with Polyposis].

Introduction: Olfaction is frequently affected in chronic rhino-sinusitis with polyposis and has been recognised to have important impact on quality of life. Surgical resolution on cases of maximal medical therapy failure is an option to relieve symptoms, with debates as to how extensive surgery should be. A more radical approach will achieve better disease control with less relapse, but can also compromise olfaction.

Structure of the rat nasal mucosa after acute and chronic hyperbaric oxygen therapy.

Objective: We aimed at the identification of putative morphologic changes induced in the rat nasal mucosa by acute or chronic hyperbaric oxygen (HBO2) treatment.

Study Design: Nasal samples were obtained from three groups of eight adult Wistar rats. The first group was submitted to 30 daily sessions of 100-minute-long HBO2 treatments at 2.

Chronic hyperbaric oxygen therapy and the human nasal mucosa: increased thickness of epithelium basement membrane and moderate neutrophilic infiltration.

Objective: We aimed to identify potential morphologic changes induced in the nasal mucosa by hyperbaric oxygen (HBO) treatment.

Study Design: Biopsies were obtained from two groups of 9 individuals: the first group had a diagnosis of tinnitus and was submitted to 15 sessions of 100 min-long HBO treatments, and the latter group consisted of healthy volunteers not submitted to HBO therapy.

Methods: Small biopsies of the anterior portion of the lower nasal turbinate were collected with the help of a Hartmann forceps under direct visual inspection.
