Extracranial vertebral artery to middle cerebral artery bypass in therapeutic internal carotid artery occlusion for epipharyngeal carcinoma: A technical case report
CONCLUSION: ICA ligation with VA-MCA high-flow bypass earlier than chemoradiotherapy is useful for epipharyngeal carcinoma as it prevents carotid artery rupture and allows radical intervention.PMID:33948319 | PMC:PMC8088539 | DOI:10.25259/SNI_99_2021
ConclusionThe PR is the region in which nasopharyngeal carcinoma originates most frequently and is very important for early diagnosis. The present results indicated that this region can be examined with CBCT.
ConclusionPRF application on the pharyngeal repair after total laryngectomy enhances the healing process and consequently decreases the incidence of PCF.
In this study, the nasal and nasopharyngeal cavities of healthy male adult, with the pharyngeal recess in an open state, were scanned by CT to obtain DICOM imaging data. Then, they were imported into Mimics 20.0 to build a model which was recorded in binary STL format. Each file was imported into Geomagic studio 12.0 to construct a 3D model saved in an IGES format. Then, it was imported into ANSYS Workbench for numerical simulation of air flow field. The authors found that: 1.The pressure gradient in nasopharyngeal cavity was, located within pharyngeal recess opening, posterior wall of nasopharyngeal cupula and bottom of ...
The oropharynx belongs to the upper aerodigestive tract including the base of tongue and vallecula, the posterior pharyngeal wall, the tonsillar region and lateral oropharyngeal walls, and the soft palate and uvula. Most oropharyngeal cancers are squamous cell carcinoma (OPSCC). Similar to other head and neck cancers, OPSCCs were traditionally more often diagnosed in heavy smokers/heavy drinkers with lower income, lower socioeconomical background and frequent comorbidities related to their lifestyle.
This study therefore aimed to further investigate the prognostic role of p16+, presence of HPV DNA, or both combined in other OPSCC. MATERIAL AND METHODS: 195 other OPSCC, from patients diagnosed 2000-2018 were tested for p16, and/or presence of HPV DNA and the data correlated to outcome. RESULTS: Neither overall survival, nor disease free survival correlated to presence of p16+ or HPV DNA in other OPSCC. p16+ and HPV DNA presence were correlated (p
Patients with squamous cell carcinoma involving cervical lymph nodes without a known primary tumor (HNCUP) increasingly undergo transoral robotic surgery (TORS) to facilitate identification and treatment of occult primary tumors. Radiotherapy (RT) treatment targets for patients with HNCUP have historically been controversial and highly variable. In patients with persistent HNCUP (pT0) following TORS assisted workup, we have adopted a pharyngeal sparing RT (PSRT) approach targeting only the at-risk neck and omitting treatment of the pharynx.
We present the case of a 72-year-old man diagnosed with T3N3bM0 stage IVB hypopharyngeal squamous cell carcinoma who had been taking minocycline for approximately 18 months as a treatment for prurigo chronica multiformis. Initial treatment consisted of total pharyngolaryngoesophagectomy, bilateral neck dissection, total thyroidectomy, pharyngeal reconstruction using a free jejunal autograft, and creation of a permanent tracheostoma.
Authors: Wang JY, Liu D, Di Meng Y, Guo YY, Zhao M Abstract Laryngeal carcinoma is a common head and neck malignancy, however, the molecular mechanism of the disease has not yet been elucidated. The present study aimed to investigate the role of IGF1R antisense imprinted non-protein coding RNA (IRAIN) long non-coding (lnc)RNA in laryngeal carcinoma. In total, specimens of healthy pharynx tissue from 6 healthy individuals, carcinoma tissue and paracancerous tissue from 37 patients with laryngeal carcinoma were used in this study. The single nucleotide polymorphism (SNP) rs8034564 was used to distinguish the two pare...
Endoscopic submucosal dissection (ESD) has gained wide acceptance as a minimally invasive and curative surgery for superficial head and neck carcinoma. However, the safety of ESD for superficial pharyngeal carcinoma after radiotherapy has not been elucidated. Superficial hypopharyngeal carcinoma of the left pyriform sinus developed in a 76-year-old man who had undergone concurrent chemoradiotherapy for T2N2bM0 pyriform sinus carcinoma on the opposite side 12 months before. He underwent ESD without complications.
CONCLUSION: The submental flap reconstruction for moderately sized non-circumferential hypopharyngeal defects is a recommended treatment option. PMID: 32808843 [PubMed - as supplied by publisher]
