Background: Granulomatosis with polyangiitis (GPA) otologic manifestations include conductive and sensorineural hearing loss (HL). Vasculitis is assumed to be the primary cause of otologic manifestations. Deaf patients and patients with HL who do not benefit from hearing aids can benefit from cochlear implants (CI).

Rehabilitating hearing loss is highly important due to its positive impact on the ability to understand speech, and the related consequences on family, social and work communication abilities. Children with hearing loss have learning difficulties that adversely affect speech and language acquirement. Most patients with hearing loss can use conventional hearing aids that are partially or completely placed in the external ear canal.

Objectives: The management of children with acute mastoiditis (AM) is still debated. Some advocate computed tomography (CT) and cortical mastoidectomy (CM) for all cases while others favor a more conservative management. This study assesses the safety and outcome of a conservative management scheme, with immediate myringotomy and postauricular needle aspiration (PANA) of a subperiosteal abscess (SPA).

Objectives: The aim of this study was to assess a new device designed to safely remove cerumen from the external auditory canal in an office setting with minimal training.

Methods: The research was conducted in the Department of Otolaryngology at Kaplan Medical Center in Israel. Patients with cerumen were treated with the device.

Background: Advanced airway management is composed of a set of vital yet potentially difficult skills for the prehospital provider, with widely different clinical guidelines. In the military setting, there are few data available to inform guideline development. We reevaluated our advanced airway protocol in light of our registry data to determine if there were a preferred maximum number of endotracheal intubation (ETI) attempts; our success with cricothyroidotomy (CRIC) as a backup procedure; and whether there were cases where advanced airway interventions should possibly be avoided.

Objective: Elevated blood glucose levels (BGL) are known to be part of the physiologic response to stress following physical trauma. We aimed to study whether a measured BGL might help improve accuracy of field triage.

Methods: We conducted a retrospective study using the Israel Defense Forces Trauma Registry.

Background: Current research in trauma resuscitation indicates that it is important to strike a balance between withholding intravenous fluid therapy, on one hand, and giving too much, on the other. The Israel Defense Forces' former protocol for prehospital fluid administration in the trauma setting was intended to navigate this balancing act. It turned out that the protocol was not being appropriately implemented in field conditions.

Objective: We assessed the causes of death of military casualties in order to determine the characteristics of injury and to determine how survivability can be improved.

Methods: A retrospective review of the trauma registry of the Israel Defense Forces was conducted. The causes of death were determined.

Objective: Physicians and paramedics in the Israel Defense Forces are trained to perform advanced medical procedures using standardized training modalities, such as manikins. We studied the association of experience using these training modalities with self-reported confidence in procedure performance.

Methods: Providers were sent a questionnaire regarding their experience with and self-confidence levels for performing endotracheal intubation, cricothyroidotomy, needle chest decompression, tube thoracostomy, and intraosseous infusion.

Background: Management of combat casualties should optimize outcomes by appropriate patient triage, prehospital care, and rapid transport to the most capable medical facility, while avoiding overwhelming individual facilities.

Methods: Planning the medical support for the campaign was done by the medical department of the IDF Southern command in cohort with the medical department of the Homefront command. Data collection and analysis were done by the Trauma Branch of the Medical corp.

Background: The criteria for tonsillectomy for recurrent tonsillitis were established by prospective studies in the pediatric population and are applied to adults as well. No studies have been conducted to assess whether these guidelines are followed.

Objectives: To examine the eligibility for tonsillectomy of tonsillectomized patients who were referred because of recurrent acute tonsillitis.

Objectives: Evaluate outcome and diagnostic yield of capsule endoscopy (CE) in soldiers with suspected small bowel disease, in comparison to traditional diagnostic procedures.

Methods: 27 consecutive soldiers who underwent CE between June 2002 and February 2004 were enrolled. Results of CE were compared to standard techniques.

Conclusion: The hemilaryngeal flap is a technique for hypopharyngeal reconstruction with the use of adjacent uninvolved tissue. The technique's advantages are that it is technically simpler than other surgical techniques for hypopharyngeal reconstruction, and involves no donor site morbidity. Its disadvantages are that it only can be employed in tumors which are confined to one side of the hemilarynx, and also there is always potential for skip lesions and incomplete resection.

Background: The external approach is the golden standard for sinonasal tumor removal but is associated with several side effects, including facial scars, intracranial and extracranial complications, a long hospitalization period and high costs. Endoscopic sinus surgery enables resection of benign and selected malignant sinonasal tumors and has the advantages of no facial scars, better functional and structural preservation of the sinonasal complex, minimal trauma to surrounding tissue, a shorter hospitalization stay and lower costs.

Objectives: To evaluate the advantages and limitations of endoscopic resection of benign and malignant sinonasal tumors, their recurrence and complication rates.
