Determination of Tympanostomy Tube Types for Otitis Media with Effusion in Patients with Cleft Palate: Comparison between Paparella Type 1 and Type 2 Tubes.

This study examined the effects of different types of tympanostomy tubes in pediatric patients undergoing cleft palate (CP) surgery in order to provide guidance for the proper insertion of tympanostomy tubes in the management of otitis media with effusion (OME). A total of 101 ears with middle ear effusion in 51 patients with CP were included in this study. Patients underwent palatoplasty and tympanostomy tube surgery at the same time.

Surgical Outcomes of Simultaneous Cochlear Implantation and Intracochlear Schwannoma Removal.

Objective: Intracochlear schwannoma is very rare, and complete loss of hearing is inevitable after the removal of this tumor. Here, we discuss cochlear implantation (CI) performed simultaneously with the removal of an intracochlear schwannoma.

Study Design: Retrospective single-center study.

Improved Bone Conduction Hearing After Middle Ear Surgery: Investigation of the Improvement Mechanism.

Objectives: When performing middle ear operations, such as ossiculoplasty or stapes surgery, patients and surgeons expect an improvement in air conduction (AC) hearing, but generally not in bone conduction (BC). However, BC improvement has often been observed after surgery, and the present study investigated this phenomenon.

Methods: We reviewed the preoperative and postoperative surgical outcomes of 583 patients who underwent middle ear surgery.

Differential expression of podoplanin in metastatic lymph node is associated with extranodal extension in oropharyngeal cancer.

This study aimed to investigate the spatial distribution and clinical significance of podoplanin expression in the metastatic lymph nodes of oropharyngeal squamous cell carcinomas (OPSCCs). The immunohistochemical podoplanin expression in the metastatic lymph nodes was evaluated in the pathologic specimens of 47 consecutive OPSCC patients. Clinicopathologic factors, including podoplanin expression and extranodal extension (ENE) status, were analyzed.

Hearing aids are still beneficial to patients, even if they have a low speech discrimination.

Purpose: A speech discrimination score (SDS) is a predictor for the successful use of hearing aids (HAs). This study is to evaluate the efficacy of HAs in patients with a low or poor SDS.

Methods: We enrolled 186 ears using HAs, with an unaided SDS ≤ 64%.

Surface control and cryogenic durability of transparent CNT coatings on dip-coated glass substrates.

Transparent carbon nanotube (CNT) coatings were deposited on boro-silicate glass substrates by dip-coating. Ultraviolet-visible (UV) spectra, surface resistance measurement, and the wettability tests were used to investigate the optical transmittance and electrical properties of these CNT coatings. The changes in electrical and optical properties of these coatings were observed to be functions of the number of dip-coating cycles.
