Objective: This study aims to evaluate the efficacy and safety of the modified push-through technique in bilateral same-day myringoplasty for patients with chronic otitis media. Bilateral myringoplasty, while advantageous in terms of cost and recovery time, is often avoided due to the perceived risks, particularly iatrogenic sensorineural hearing loss (SNHL). This study contributes to the limited literature on simultaneous bilateral ear surgeries by assessing surgical outcomes, including graft success rates and postoperative hearing improvement.

Cytomegalovirus (CMV) reactivation is a known complication in patients with hematological cancers and those who undergo stem cell transplants, often resembling cancer relapse. CMV lymphadenitis, an infection localized to the lymph nodes, can be difficult to distinguish from lymphoma recurrence based on clinical and radiological findings alone. We report a case of a 40-year-old male treated for Hodgkin lymphoma who presented with cervical lymphadenopathy nine months after treatment.

Objective: We investigated the accuracy of imaging modalities in diagnosis and outcome of otitis media with effusion by correlating the imaging findings with the preoperative otomicroscopic examinations, tympanometric results, and intraoperative findings in patients who underwent cochlear implant surgery.

Methods: The results of the preoperative physical examination and intraoperative findings of patients younger than 18 years who underwent cochlear implant surgery at a single tertiary institution were recorded from their medical charts. Tympanometries, which were performed in maximum 1 week prior to imaging modalities, were analyzed.

Article Synopsis
  • - The study aimed to explore the impact of adipose tissue-derived stromal vascular fraction on healing pharyngocutaneous fistulas in rats after laryngeal surgery.
  • - Eleven rats were divided into study and control groups, with the study group receiving an injection of the stromal vascular fraction post-surgery.
  • - While epithelialization was greater in the study group, the differences weren’t statistically significant; however, there was less mucosal injury and cell infiltration in the study group compared to controls, suggesting some potential benefits.

Article Synopsis
  • The study investigates how papaverine affects myringosclerosis (MS) in rats, focusing on its impact on hearing issues caused by the condition.
  • Twenty Wistar albino rats were divided into four groups to test different treatments, including myringotomy, saline application, and both systemic and topical papaverine.
  • Results indicated that papaverine increased the severity of MS, possibly due to its vasodilating effects that lead to higher levels of oxygen-derived free radicals, warranting further evaluation of its implications on MS.

Purpose: The aim of this study is to compare the results of auditory perception tests and speech sound evaluations with electrode array length in patients with Mondini deformity.

Methods: The study included 14 patients who underwent cochlear implantation and radiologically confirmed Mondini deformity between 2007 and 2021 in our clinic. While 7 patients received standard electrode arrays from the MED-EL brand, the remaining 7 received shortened electrode arrays from the MED-EL brand.

Objective: This study aimed to highlight the differences in the clinical management and treatment of sudden sensorineural hearing loss (SSNHL) due to the impact of the Coronavirus Disease 2019 (COVID-19) pandemic.

Methods: This study compared patients diagnosed with SSNHL between March 2020 and March 2022, following the first reported case of COVID-19 in our country, with patients diagnosed between March 2018 and March 2020. The evaluation encompassed demographic characteristics, comorbidities, other ear-related complaints, hearing loss thresholds at each frequency, medical treatment administered, treatment duration, and post-treatment follow-up audiograms.

Article Synopsis
  • The study explored the relationship between oral microbiota dysbiosis and oral cavity cancers by comparing patients with cancer to matched healthy controls.
  • Data was collected through questionnaires, clinical examinations, and saliva DNA sequencing to analyze the microbial composition.
  • Results indicated that cancer patients had poorer oral health and a distinct microbial profile, with specific bacterial species linked to the disease, suggesting interactions between oral bacteria and cancer development.

Objectives: The Intranasal Schirmer test (INS) is an easy to administer test that can yield objective measurement of the quantity of nasal secretion and has been studied in patients with various nasal and systemic pathologies; however, the role of INS in patients with allergic rhinitis remains unclear. Our aim was to determine the relationship between various allergic symptoms and the Intranasal Schirmer Test (INS) score and to evaluate the utility of INS in determining treatment effect in patients with allergic rhinitis.

Methods: This prospective study included patients with allergic rhinitis who were randomly divided into 3 treatment groups (nasal steroid only, oral antihistamine only, nasal steroid and oral antihistamine).

Middle ear adenomatous neuroendocrine tumor (MEANT) is a rare entity and accounts for approximately 2% of all middle ear tumors. Histologically, the presence of neuroendocrine and glandular structures has led to the use of a wide variety of terminologies such as adenoma, carcinoid tumor, and neuroendocrine tumor. The patients usually have nonspecific symptoms such as unilateral hearing loss, auditory fullness, tinnitus, and otalgia.

Objectives: The objectives of this study were to evaluate the role of oxidative stress in benign paroxysmal positional vertigo (BPPV) by measuring urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG), 8-hydroxy-guanosine (8-OHG), and 8-hydroxy-guanine levels.

Methods: Thirty-one adult female patients diagnosed with BPPV were included in this study. Patients with central pathologies and other peripheral causes of vertigo were excluded from the study.
