AI Article Synopsis

  • PET is an imaging technique that helps monitor malignancies but is not specific to tumors.
  • A case is presented involving a patient with a history of rectum cancer and lentigo maligna who had a PET-CT scan showing increased activity in the larynx.
  • Initially thought to indicate a new primary cancer, the finding was ultimately identified as a Teflon granuloma.

Article Abstract

Positron emmision tomography (PET) is successfully used to monitor malignancies. Unfortunately it is not tumor specific. We present a case with history of rectum cancer and lentigo maligna who underwent PET-CT which revealed an increased uptake in the larynx. What was first considered as a third primary turned out to be a Teflon granuloma.

Trigeminal neuralgia (TN) is characterized by excruciating facial pain usually caused by neurovascular compression of the trigeminal nerve roots. TN can be treated medically or invasively. Microvascular decompression is the procedure of choice and usually results in complete symptom relief.

Article Synopsis
  • The study investigates the occurrence of suture granulomas, a complication in canthal surgery, focusing on their incidence and risk factors.
  • A total of 758 surgeries were reviewed, revealing that 2.4% resulted in granulomas, mainly linked to specific suture materials, particularly uncoated polyester.
  • Results suggest that using absorbable or monofilament sutures can significantly reduce the risk of developing suture granulomas after surgery.

Aim: To review our experience with patients presenting with recurrent trigeminal neuralgia (TN) and who have undergone repeat microvascular decompression surgery (rMVD).

Material And Methods: This retrospective observational study was conducted at the Department of Neurosurgery at a university hospital. Patients who initially experienced complete pain relief after the first MVD but later had a recurrence of TN symptoms which required an rMVD were included in the study.

Background And Objectives: Microvascular decompression (MVD) is the primary surgical intervention for trigeminal neuralgia (TN), with Teflon being the most conventional decompressing material. However, Teflon has been associated with adhesion and granulomas after MVD, which closely correlated with the recurrence of TN. Therefore, we developed a new technique to prevent direct contact between Teflon and nerve.

Background: Microvascular decompression (MVD) is an effective nondestructive neurosurgical procedure for trigeminal neuralgia (TN). However, some patients may undergo surgery failure or experience pain recurrence, sparking debates on the need for reoperation.

Methods: We conducted a retrospective analysis of 103 cases of patients with primary TN who underwent redo MVD at our center between January 2020 and December 2022.
