Hemostatic Control with Gelatin Sponge and Quantum Molecular Resonance Coagulation in a Case of Glomus Tympanicum.

Surgical removal of tumor is the primary treatment of choice for glomus tympanicum (GT). However, because the tumor has abundant blood flow, bleeding control is crucial, and preoperative embolization may be performed. Here, we report the case of a 46-year-old female who visited our hospital with a complaint of right pulsatile tinnitus.

Characteristics of repeated recidivism in surgical cases of cholesteatoma requiring canal wall reconstruction.

Objective: Few reports discuss the characteristics of repeated recidivism of cholesteatoma. We describe the clinical characteristics of patients with cholesteatoma who experienced at least two recidivism episodes after initial surgery for cholesteatoma requiring canal wall reconstruction.

Methods: We reviewed the medical records of 11 patients who underwent surgery for cholesteatoma with canal wall reconstruction at our department between April 2008 and March 2018 and subsequently experienced two relapses that necessitated revision surgery involving tympanomastoidectomy with canal reconstruction.

A Case of Gorham-Stout Disease Treated with Fistula Closure by Transmeatal Approach.

Gorham-Stout disease, a rare and intractable disease of unknown etiology, causes systemic bone lysis and replacement with lymphoid tissue. Here, we report a case of Gorham-Stout disease with cerebrospinal fluid leakage in a 16-year-old boy. The patient complained of nasal discharge, right ear obstruction, fever, and headache.

A Case of Cochlear Implantation in a Patient with Superficial Siderosis.

Superficial siderosis is a disease in which iron from hemoglobin is deposited in the central nervous system, resulting in conditions such as progressive sensorineural hearing loss, cerebellar ataxia, dementia, and pyramidal signs. A 30-year-old man with superficial siderosis received a cochlear implant in the left ear, which had shown complete hearing loss. Good auditory responses were obtained at 14 days after implantation.

A Case of Skull Base Chondrosarcoma with Intraoperative Trigemino-Cardiac Reflex.

A 75-year-old female patient presented with a suspected recurrence of a clival chordoma. The tumor was resected using the infratemporal fossa type B and anterior petrosal approach with the help of a neurosurgeon. During cauterization of the trigeminal nerve, the patient developed cardiac arrest for approximately 10 seconds because of the trigemino-cardiac reflex (TCR).

Clinical characteristics, the diagnostic criteria and management recommendation of otitis media with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV) proposed by Japan Otological Society.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a form of necrotizing vasculitis with few or no immune deposits. It primarily affects small and medium blood vessels. AAV is classified into three categories, granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangitis (EGPA), and two major ANCAs, proteinase 3 (PR3)-ANCA or myeloperoxidase (MPO)-ANCA are involved in their pathogenesis.

Three Dimensional Motion Analysis of Hand Tremors During Endoscopic Ear Surgery.

Background: Endoscopic surgery is developing in various clinical specialties. During ear endoscopic surgery, a surgeon has to hold an endoscope with one hand and operate the surgical instruments with another hand. Therefore, the stability of the surgeon's hand affects the field of surgical view and quality of the surgery considerably.

Usefulness of High-Resolution 3D Multi-Sequences for Peripheral Facial Palsy: Differentiation Between Bell's Palsy and Ramsay Hunt Syndrome.

Objective: To investigate the usefulness of magnetic resonance imaging (MRI) including three-dimensional (3D) sequences in the differentiation between Bell's palsy (BP) and Ramsay Hunt syndrome (RHS).

Study Design: A prospective study.

Setting: Tertiary care center.

Sequential motion of the ossicular chain measured by laser Doppler vibrometry.

Objective: In order to help a surgeon make the best decision, a more objective method of measuring ossicular motion is required.

Methods: A laser Doppler vibrometer was mounted on a surgical microscope. To measure ossicular chain vibrations, eight patients with cochlear implants were investigated.

Analysis of Direct Simultaneous Measurement of Glottal Airflow Velocity, Subglottal Pressure, and High-Speed Imaging Using Flexible Transnasal Endoscope in a Human Subject.

It is difficult to directly observe glottal airflow velocity just above the glottis due to sensor size requirements and limited accessibility. We developed a miniature hot-wire probe and flexible fiberscopic high-speed imaging system for human examinations. Simultaneous direct measurement of glottal airflow velocity, subglottal pressure, and vocal fold vibration was achieved in a patient who was treated with a T-tube for tracheal stenosis.

Clinical features and treatment outcomes of otitis media with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV): A retrospective analysis of 235 patients from a nationwide survey in Japan.

Objective: We aimed to analyze clinical features and treatment outcomes of otitis media caused by antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), i.e. otitis media with AAV (OMAAV).

Staged resection for vestibular schwannoma.

Conclusion: Surgery remains the preferred option for large vestibular schwannoma (VS). The presence of unpredictable intraoperative difficulties may convince the operator to suspend the surgery to avoid risks to patient life. Additional surgeries may be mandatory and are better performed using a transcochlear approach.

Sequential multipoint motion of the tympanic membrane measured by laser Doppler vibrometry: preliminary results for normal tympanic membrane.

Background: Numerous studies have reported sound-induced motion of the tympanic membrane (TM). To demonstrate sequential motion characteristics of the entire TM by noncontact laser Doppler vibrometry (LDV), we have investigated multipoint TM measurement.

Materials And Methods: A laser Doppler vibrometer was mounted on a surgical microscope.

Deleted in Esophageal Cancer 1(DEC1) is down-regulated and contributes to migration in head and neck squamous cell carcinoma cell lines.

Background: Previous studies have shown that the expression of Deleted in Esophageal Cancer 1 (DEC1) is significantly reduced in esophageal squamous cell carcinoma. Patients with head and neck squamous cell carcinoma (HNSCC) often develop esophageal carcinomas.

Materials And Methods: We analyzed the expression of DEC1 and histone modifications in HNSCC cell lines.

Successful resection of posterior mediastinal thyroid cancer by partial sternotomy combined with video-assisted thoracoscopy.

We report on a rare case of substernal thyroid carcinoma extending into the posterior mediastinum of a 48-year-old man. The tumor was resected by partial sternotomy and a small anterior thoracotomy, combined with video-assisted thoracoscopy. The pathological diagnosis was of a well differentiated papillary adenocarcinoma of the thyroid with mediastinal extension.

[Superselective intraarterial chemotherapy using low dose CBDCA and Pirarubicin with concurrent radiotherapy for head and neck cancer].

To study the effects of superselective intraarterial chemotherapy with low-dose CBDCA, Pirarubicin, and concurrent radiotherapy on head and neck cancer, we compared primary cancer response and histopathological effective grades in 66 patients (more than T2) divided into radical and preoperative radiotherapy groups. The radical group (n=33) showed a 75.7% response in primary cancer, i.
