Preoperative imaging modalities to predict the risk of regional nodal recurrence in well-differentiated thyroid cancers.

Introduction Thyroid cancer incidence has increased in the previous 2 decades. Preoperative identification of lymph node metastasis is a suggested risk factor associated with recurrence following thyroidectomy. Objectives We aimed to evaluate the accuracy of preoperative radiologic investigations of nodal status in determining the postoperative risk of regional nodal recurrence in cases of well-differentiated thyroid cancer.

The value of routine preoperative testing in the prediction of operative hemorrhage in adenotonsillectomy.

Medical records were reviewed to identify subjects who ranged in age from 1 to 18 years and who had undergone tonsillectomy with or without adenoidectomy. Data obtained included patient demographic information, relevant medical history, history of hemorrhage, family history of hemorrhagic disorders, and drug history. Laboratory data obtained included a baseline coagulation screening to determine prothrombin time, activated partial thromboplastin time, and platelet count.

Virtual reality simulation in ear microsurgery: a pilot study.

Classically, teaching of otological micro procedures is achieved by cadaveric dissection of the temporal bones, achieved by attending expensive temporal bone dissection courses. The difficulty in acquiring cadaveric specimens and the cost of courses has led to the development of alternative techniques. The aim of this study is to evaluate the efficacy of using virtual reality temporal bone simulation in training otolaryngology residents for mastoidectomy procedures.

Benchmarking the post-accreditation patient safety culture at King Abdulaziz University Hospital.

Background And Objectives: Accreditation is an internationally recognized evaluation process used to assess, promote, and guarantee efficient and effective patient care and safety. Saudi Arabia is one of the first countries in the eastern Mediterranean region to implement health care accreditation standards. This study provides valuable information pertaining to the impact of accreditation in the unique multicultural, multilingual competitive environment at King Abdulaziz University Hospital in Saudi Arabia.

Role of multislice computed tomography and local contrast in the diagnosis and characterization of choanal atresia.

Objective. To illustrate the role of multislice computed tomography and local contrast instillation in the diagnosis and characterization of choanal atresia. To review the common associated radiological findings.

Distortion product otoacoustic emission for the screening of cochlear damage in children treated with cisplatin.

Objectives/hypothesis: To detect subtle hearing changes by measuring otoacoustic emissions in patients treated with a first dose of cisplatin.

Study Design: Prospective study.

Methods: We recruited 26 patients (mean age at treatment, 11.

Computed tomography and magnetic resonance imaging findings before and after treatment of patients with malignant external otitis.

The aim of our prospective study is to illustrate the role of computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis and delineation of the extent of disease in malignant external otitis (MEO) at presentation and following successful treatment. The study was performed at Tertiary academic referral center. We included 18 patients (16 males and 2 females; age, 49-79 years; mean, 65.

Prevalence of hearing loss among Saudi type 2 diabetic patients.

Objective: To compare hearing impairment and audiometric shapes associated with type 2 diabetes mellitus (T2DM) with an age-matched control group in the Saudi population.

Methods: This is an observational case-control study at a tertiary academic referral center. We recruited 196 individuals (age; 29-69 years) attending the Department of Otolaryngology, King Abdulaziz University Hospital between January 2005 to December 2009, and grouped them into T2DM (n=109) and control (n=87) groups.
