Mechanism of ear canal button battery injury and strategies for mitigation of damage.

Objectives: In this study, the damage caused by button batteries (BB) trapped in the ear canal (EC) and strategies to reduce this damage before their removal were investigated .

Methods: After four EC models prepared from freshly frozen cadaveric bovine ears were thawed, 3 V lithium BBs were placed in the channels. After a three-hour period of preliminary damage, nothing was applied to the first EC model, the second EC model underwent saline administration, the third EC model underwent boric acid administration, and the fourth EC model underwent the administration of 3% acetic acid.

Injury Mechanism of Button Batteries in the Nasal Cavity and Possible Mitigation Strategies During Impaction.

Objective/hypothesis: Button batteries (BBs) impacted in the nasal cavity can cause several complications. Understanding the injury mechanism and developing possible mitigation strategies can reduce these complications.

Study Design: Cadaveric sheep nasal septum model.

The Prognostic Value of Circulating Inflammatory Cell Counts in Sudden Sensorineural Hearing Loss and the Effect of Cardiovascular Risk Factors.

Objectives: Recent studies suggest that elevated neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are poor prognostic factors in sudden sensorineural hearing loss (SSNHL). We aimed to investigate the accuracy of this hypothesis by taking into account the effect of cardiovascular risk (CVR) factors.

Methods: Medical records of 122 patients with SSNHL were reviewed retrospectively and grouped into 2 as; patients without CVR (group 1; n = 68) and patients having CVR (group 2; n = 54).

A potential post-removal pH neutralization strategy to mitigate nasal button battery injuries.

Objective: Button batteries (BBs) impacted in the nose of children can cause septal perforation, synechia, atrophy, necrosis and deformities such as saddle nose. Developing mitigation strategies that can reduce tissue damage after BB removal can decrease these complications.

Methods: 3 V lithium BBs were placed on the cadaveric sheep nasal septum model segments.

Does Postauricular Incision Cause Auricula Protrusion After Tympanoplasty?

Background: An ear surgery can be performed via transcanal, endaural, or postauricular approach according to the surgeon's desicion. The postauricular one is the most commonly performed approach.

Objective: The objective of this study was to evaluate whether preferring postauricular approach during ear surgery cause auricular protrusion in over time.

Comparison of two modern and conventional tonsillectomy techniques in terms of postoperative pain and collateral tissue damage.

Purpose: To compare the tonsillectomy operations performed with bipolar radiofrequency clamp (BRC), plasma blade (PB), and cold dissection (CD) techniques in terms of postoperative pain and collateral tissue damage.

Methods: This is a prospective randomized comparative cohort study conducted in a tertiary hospital. A total of 50 patients who underwent tonsillectomy in our institution met the inclusion criteria.

Possible prediction of patterns of cervical lymph node spread based on primary tumor location in papillary thyroid carcinomas.

Backround/aim: Papillary thyroid carcinomas (PTC) frequently metastasize to regional lymph nodes. Our purpose was to investigate the predictive role of tumor location for lymph node metastasis pattern in PTCs.

Materials And Methods: Medical records of 110 PTC patients were reviewed retrospectively.

Safety of outpatient admission and comparison of different surgical techniques in adult tonsillectomy.

Purpose: To investigate the safety of outpatient admission and the effects of surgical technique in tonsillectomy operations of adult patients.

Methods: The digital database was scanned for patients aged ≥ 15 years that underwent tonsillectomy in our institution between years 2014 and 2018. Demographic and clinical characteristics, the surgical technique, length of stay (LOS) in hospital, re-admissions after discharge, complications and interventions performed were recorded.

Protective/restorative Role of the Adipose Tissue-derived Mesenchymal Stem Cells on the Radioiodine-induced Salivary Gland Damage in Rats.

Background: To analyze protective/regenerative effects of adipose tissue-derived mesenchymal stem cells (ADMSC) on I-Radioiodine (RAI)-induced salivary gland damage in rats.

Materials And Methods: Study population consisted of controls (n:6) and study groups (n:54): RAI (Group 1), ADMSC (Group 2), amifostine (Group 3), RAI+amifostine (Group 4), concomitant RAI+ADMSC (Group 5) and RAI+ADMSC after 48 h (Group 6). We used light microscopy (LM), transmission electron microscopy (TEM), and salivary gland scintigraphy (SGS), and analyzed data statistically.

The effect of caffeic acid phenethyl ester (CAPE) on tympanosclerosis.

Objective: To investigate the effects of caffeic acid phenethyl ester (CAPE) on tympanosclerosis.

Materials And Methods: Thirty-two male Sprague Dawley rats were separated into 4 groups as CAPE (n = 10), alcohol (n = 10), control (n = 8) and normal (n = 4) groups. All tympanic membranes except normal group were myringotomised and type 3 Streptococcus pneumoniae strains was injected into their middle ears.
