Outcomes and Prognostic Factors in Patients With Untreated Head and Neck Squamous Cell Carcinoma.

Objectives: Although several studies have reported the treatment prognosis in squamous cell carcinoma of the head and neck, few studies exist on the prognosis and mortality-related risk factors in untreated cases. This study aimed to determine the outcomes of patients with head and neck squamous cell carcinoma who underwent no treatment and investigate the associated factors.

Methods: This retrospective, single-institution study initially included 718 patients with head and neck cancer who visited our hospital between January 2015 and December 2021; 43 untreated patients were included in the final analysis.

Utility of 3D double-echo steady-state with water excitation (3D-DESS-WE) in diagnosing intraparotid facial nerve schwannoma: A case report.

Differentiating intraparotid facial nerve schwannoma from other parotid tumors, particularly pleomorphic adenoma, is clinically crucial due to significant differences in treatment approaches. We report a case of a male patient in his 70s presenting with a left parotid mass. Magnetic Resonance Imaging (MRI) revealed a mass within the left parotid gland exhibiting the characteristic ``target sign''.

Safety of cricotracheostomy with skin and tracheal membrane flaps for severe COVID-19 patients.

Objective: Airway surgery is performed for COVID-19 patients who require long-term tracheal intubation and mechanical ventilation. Tracheostomy sometimes causes postoperative complications represented by bleeding at a relatively high rate in COVID-19 patients. As an alternative surgical procedure to tracheostomy, cricotracheostomy may reduce these complications, but few studies have examined its safety.

Radiological features of thyroid-like low-grade nasopharyngeal papillary adenocarcinoma: case series and systematic review.

Purpose: To comprehensively summarize the clinical data and CT/MRI characteristics of thyroid-like low-grade nasopharyngeal papillary adenocarcinoma (TL-LGNPPA).

Methods: Twenty-seven lesions from 25 study articles identified through a systematic review and three lesions from our institution associated with TL-LGNPPA were evaluated.

Results: The mean age of the patients at diagnosis was 35.

Extent of thyroidectomy and paratracheal lymph node dissection in total pharyngolaryngectomy for pyriform sinus cancer, and recurrence, survival, and postoperative hypoparathyroidism: A multicenter retrospective study.

Background: Total pharyngolaryngectomy (TPL) is standard treatment for hypopharyngeal cancer. However, extensive thyroidectomy and paratracheal nodal dissection (PTND) can cause hypoparathyroidism. We sought to determine the optimum extent of resection.

A comparison between sniffing and blowing for olfactory testing before and after laryngectomy.

Purpose: Olfactory dysfunction occurs after laryngectomy due to the loss of nasal airflow and inability to sniff. However, the reason for the loss of olfactory function after laryngectomy is unclear on evaluation with sniffing type tests performed individually. It is expected that the sensorineural olfaction remains, and the results of the sniffing test would be negative, while that of the odour-blowing test would be positive.

Imaging predictor of ophthalmic involvement in maxillary sinus cancer during super selective intra-arterial cisplatin infusion and concomitant radiotherapy (RADPLAT).

Objective: To investigate the predictability of ophthalmic artery involvement in maxillary sinus cancer using preprocedural contrast enhanced CT and MRI.

Methods: We analyzed advanced (T3, T4a, and T4b) primary maxillary sinus squamous cell carcinoma treated with super-selective intra-arterial cisplatin infusion and concomitant radiotherapy (RADPLAT) from Oct 2016 to Mar 2020. Two diagnostic radiologists evaluated the tumor invasion site around the maxillary sinus using preprocedural imaging.

Radiological differences in computed tomography findings and texture analysis between cystic lymph node metastases of human papillomavirus-positive oropharyngeal cancer and second branchial cysts.

Purpose: The study aimed to analyse radiological differences in computed tomography (CT) findings and texture analysis between cystic lymph node metastases (CNM) in human papillomavirus (HPV)-positive oropharyngeal cancer (OPC) and second branchial cleft cysts (2 BC).

Material And Methods: Patients with pathological evidence of CNM-HPV-OPC and 2 BC, who underwent contrast-enhanced CT, were retrospectively evaluated. The evaluated characteristics include age, sex, and CT findings.

Pre-treatment MRI predictor of high-grade malignant parotid gland cancer.

Objectives: We aimed to evaluate pre-treatment MRI predictors of high-grade malignant parotid gland cancer by comparing MRI findings and texture parameters between high-grade and intermediate/low-grade parotid gland cancers.

Methods: Patients underwent a pre-treatment MRI and had a parotid gland cancer resection with pathological evaluation. Evaluation objectives included attributive factors such as age and gender, several MRI findings of T1- and T2-weighted images, post-contrast fat suppression T1-weighted images, ADC value and 40 texture parameters calculated from T2-weighted axial images.

[Clinical Analyses of 115 Patients with Peritonsillar Abscess].

The clinical data of 115 patients with peritonsillar abscess (98 men and 17 women) treated between May 2011 and March 2014 were analyzed. We examined 9 items; the age, sex, affected side, duration of hospitalization, method of drainage, smoking history, history of diabetes, antibacterial drugs used, and the isolated bacteria. The disease predominantly affected males in their 30s (27.

[A case of blunt common carotid artery injury following minor trauma].

Cervical major blood vessel injuries often produce acute ingravescence of the circulatory dynamics. Therefore, if immediate treatment is not given, fatal complications can occur, resulting in death. Common carotid artery (CCA) injuries in particular are often associated with fatal outcomes.

[A case of parotid pleomorphic adenoma metastasis to multiple organs].

In January 2011, a 64-year-old woman who had undergone tumor resection for pleomorphic adenoma of the left parotid gland four times since her first operation in 1996 visited an orthopedist in our hospital complaining of pain in her right lower limb. Computed tomography (CT) of the whole body showed multiple tumors on the left parotid gland, right kidney, the sacrum, and both lungs. Biopsy of the sacral region and right nephrectomy were performed based on a clinical diagnosis of sacral and pulmonary metastases from renal cell carcinoma, and palliative radiation therapy was immediately begun on the sacral region.
