To determine the risk factor for developing complications in patients undergoing removal procedures for foreign bodies (FBs) in the external auditory canal (EAC) in the otolaryngology (ENT) emergency unit. Cases involving patients with EAC FBs treated at the ENT emergency unit of a tertiary medical center were retrospectively recruited. Patients were classified into the age < 10 years and ≥10 years groups.

Our study aims to identify the risk of cholesteatoma development in patients with osteoma and proposes a stepwise approach to managing patients with EAC osteoma. The maximum diameter of the osteoma was measured in axial and coronal views on high-resolution computed tomography (HRCT).

High-throughput sequencing technology was used to explore the effects of five treatments, namely, control (CK), desulfurization gypsum (T1), soil ameliorant (T2), organic fertilizer (T3), and desulfurization gypsum compounds soil ameliorant and organic fertilizer (T4), on soil physicochemical properties and fungal community diversity, composition, and structure of saline-alkali soil in Hetao Plain, Inner Mongolia. The results showed that compared with those in CK, the contents of available phosphorus, available potassium, organic matter, and alkali hydrolysis nitrogen were significantly increased in modified material treatments, and the T4 treatment significantly decreased soil pH.

We examined the speech perception and quality of life (QOL) of bilateral prelingually deaf children who underwent sequential CI, considering the effects of age at the time of second implantation and interimplant interval.
Methods: We enrolled 124 Mandarin-speaking participants who underwent initial cochlear implant (CI1) in 2001-2019 and a second CI (CI2) in 2015-2020.
(1) Background: BCC is a sporadic disease that develops in areas of the skin not exposed to the sun. Perianal BCC, which occurs in the anorectal region, accounts for less than 0.2% of all BCC cases.

- Exoscope, a surgical tool, has been increasingly used in ear surgeries, though most operations still utilize microscopes or endoscopy.
- This study involved 15 patients and collected feedback from various surgical team members through a detailed questionnaire, evaluating the performance and experience of using the exoscope.
- Results showed exoscopic surgery to be safe and effective, with high marks for image quality and magnification, but noted challenges like limited workspace and user eye strain, suggesting it has potential for broader use in otologic procedures.
Recurrent sudden sensorineural hearing loss-A literature review.
Laryngoscope Investig Otolaryngol
June 2022
Article Synopsis
- Sudden sensorineural hearing loss (SSNHL) is an urgent condition where timely treatment can benefit many, but some patients may experience unexpected recurrences. The study investigates the recurrence rates and prognosis for both first-time and recurrent SSNHL cases.* -
- A review of seven studies with 3,781 patients found that 96 experienced recurrence, with rates ranging from 1.4% to 17%, typically occurring about 2 years after the initial episode. Recovery rates were between 58%-79% for first-time patients and varied from 21% to 86% for those with recurrent SSNHL.* -
- Although no specific risk factors for SSNHL recurrence were consistently identified, potential
Purpose: The purpose of this study was to measure the incidence of complications in sudden sensorineural hearing loss (SSNHL) patients treated with intra-tympanic steroid injection (ITSI) and compare hearing recovery rates.
Materials And Methods: 123 patients with unilateral SSNHL receiving ITSIs were included in this study. Post-ITSI complications were documented including otalgia, dysgeusia, vertigo (duration>1 h), and persistent eardrum perforation.
Purpose: Sudden sensorineural hearing loss, briefly sudden deafness (SD), in the elderly remains less investigated despite rapidly aging population in most countries around the world. This study investigated whether aging process affects the treatment outcome of SD in the elderly.
Patients And Methods: Eighty patients with SD, comprising 40 geriatric patients aged >65 years and 40 non-geriatric patients aged 55-64 years, were enrolled in this study.
Declining prevalence of pediatric sudden deafness during the past two decades.
Int J Pediatr Otorhinolaryngol
April 2019
Objective: This study compared the prevalence of sudden deafness (SD) in children to investigate the evolution of pediatric SD during the past two decades.
Methods: From 1996 to 2005, totaling 358 SD patients were experienced. Of them, 25 patients (7%) aged <15 years were assigned to Group A.
Sudden Deafness during Antepartum versus Postpartum Periods.

July 2018
Objective: This study reviewed our experience in treating sudden deafness in antepartum (pregnant) and postpartum women during the past 2 decades.
Methods: From 1997 to 2016, we have recorded sudden deafness in 16 antepartum (mean age, 32 years) and 3 postpartum (mean age, 31 years) women. Sudden deafness occurred during the 1st, 2nd, and 3rd trimesters in 5, 4, and 7 antepartum women, respectively.
