Long-term Oncologic Results and Voice Outcomes in Patients With Glottic Cancer After Modified Type III Cordectomy.

Objective: Transoral laser microsurgery and radiotherapy provide high and comparable cure rates for the treatment of early glottic cancer. However, the voice outcomes after treatment remain controversial. A modified type III cordectomy technique was proposed in 2006, and preliminary results showed it to be an oncologically safe method with satisfactory voice outcomes.

Combining sinus plain film and sinus ultrasound as a screening tool for maxillary fungal sinusitis.

Background: Early identification of fungal sinusitis remains a challenge. Previously, we observed a high false negative rate of using A-mode ultrasound to diagnose maxillary fungal sinusitis. This study aims to assess the accuracy of the diagnosis of fungal maxillary sinusitis using sinus plain film and ultrasound.

Oncologic results and quality of life in patients with T3 glottic cancer after transoral laser microsurgery.

Purpose: CO transoral laser microsurgery (CO2 TOLMS) is an alternative approach to non-surgical organ preservation in selected T3 glottic squamous cell carcinoma (SCC). This study aimed to assess the oncologic results and quality of life (QOL) of patients with T3 glottic SCC after CO2 TOLMS.

Methods: Of the 44 patients who underwent CO2 TOLMS, 38 underwent QOL evaluations.

Oncologic results and quality of life in patients with squamous cell carcinoma of hypopharynx after transoral laser microsurgery.

Objective: Transoral laser microsurgery (TLM) is an alternative method for organ preservation in squamous cell carcinoma of hypopharynx (HPSCC). The purpose of this study was to analyze the oncologic results and quality of life (QOL) in HPSCC patients after TLM.

Methods: Forty-six patients who underwent TLM were included, 34 of them had QOL evaluations.

Somatosensory-evoked potentials as an indicator for the extent of ultrastructural damage of the spinal cord after chronic compressive injuries in a rat model.

Objective: Somatosensory-evoked potentials (SEPs) were found to correlate well with the disability and postoperative recovery in patients with cervical spondylotic myelopathy. Yet the exact pathophysiology behind it remains to be elucidated. This study aims to characterise the ultrastructural changes of a chronically compressive spinal cord with various SEP responses in a rat model.

Entropy-based analysis for diffusion anisotropy mapping of healthy and myelopathic spinal cord.

The present study utilized diffusion MR imaging and fractional anisotropy (FA) mapping to delineate the microstructure of spinal cord. The concept of Shannon entropy was introduced to analyze the complex microstructure of healthy and injured spinal cords based on FA map. A total of 30 volunteers were recruited in this study with informed consent, including 13 healthy adult subjects (group A, 25±3 years), 12 healthy elderly subjects (group B, 53±7 years) and 5 cervical spondylotic myelopathy (CSM) patients (group C, 53±15 years).
