Two Teflon granulomas of the nasopharynx and paravertebral space mimicking a neoplasm.
Clin Case Rep
November 2022
Teflon has been proved to be able to extravasate and infiltrate into soft tissue to form an inflammatory giant-cell foreign-body reaction, a so-called Teflon granuloma. We present a rare case report of a patient with two Teflon granulomas of the head and neck, who were first interpreted as a neoplasm.

Conventional wisdom about the posterior glottis indicates that it tends to be completely closed in men but may be open in women. Furthermore, professional singers are expected to have a completely closed posterior glottis.

- Nasal surface anesthesia is a non-invasive method for numbing that might effectively improve dental procedures, especially for kids after trauma.
- A pilot study involving 105 patients showed that using the local anesthetic Tenaphin improved anesthesia in the oral tissues, particularly in the anterior region when exposure time was longer.
- The findings suggest that nasal surface anesthesia could potentially replace or supplement traditional injection methods in the upper jaw, but more research on dosage and exposure time is needed.
Objective: Most type 1 thyroplasty implants and some common injectable materials are mechanically stiff. Placing them close to the supple vocal fold mucosa can potentially dampen vibration and adversely impact phonation, yet this effect has not been systematically investigated. This study aims to examine the effect of implant depth on vocal fold vibration and vocal output.

- The study focuses on how different types of cricothyroid joints (CTJs) impact vocal fold elongation, which is important for pitch elevation in transwomen undergoing gender dysphoria treatment.
- Researchers developed a tool using high-resolution computed tomography (HRCT) to differentiate between Type A (having a cricoid cartilage protuberance) and Type B/C (with a flat surface) CTJs.
- Findings indicated that Type A had an intercartilaginous distance of less than 1 mm, while Type B/C exceeded 1 mm, providing a clear metric for distinguishing the two joint types in clinical settings.
Article Synopsis
- This study explored how medialization thyroplasty (MT) affects the arytenoid cartilage in patients with unilateral vocal fold paralysis, focusing on biomechanical changes from an implant.
- Researchers recruited 15 patients, conducted pre- and post-operative high-resolution CT scans, and used 3D imaging software to assess changes in vocal fold length and position.
- Results showed that the implant moved the arytenoid backwards and rotated it inward, leading to a medialized and elongated vocal fold on the affected side, ultimately equalizing the length of the vocal folds during phonation.
Objectives/hypothesis: Young professional singers can easily reach very high pitches. In contrast, older singers often complain that they have to exert substantially more laryngopharyngeal force to reach the same high pitch compared with their earlier years. Various factors such as the property changes of the mucosa and ossification that impact the singing apparatus were suggested as explanations in the literature.

The aim of the study was to show the influence of the CTJ on VF elongation while singing a sustained vowel at different pitches.
Study Design: Prospective study.
Article Synopsis
- * 49 professional female singers were analyzed using 3D imaging to observe changes in their laryngeal structure at different pitch levels.
- * Results indicate that the initial octave increase in pitch is achieved through simple muscle actions, while higher pitch involves more complex movements of the arytenoid cartilages.
