AI Article Synopsis
- - Masseter spasm is defined as significant difficulty in opening the mouth after anaesthesia induction, which can complicate procedures like laryngoscopy and intubation, and occurs without any issues from the jaw joint.
- - Factors such as certain muscle relaxants, antidepressants, and high anxiety levels can contribute to the occurrence of masseter spasms.
- - This case highlights the need for anaesthesiologists to be cautious of masseter spasm risks in anxious patients undergoing antidepressant treatment, as it can create dangerous situations where ventilation and intubation are impossible.
Article Abstract
Masseter spasm after induction of anaesthesia can be generally defined as a marked difficulty in manual mouth opening that interferes and impedes direct laryngoscopy and tracheal intubation without the presence of temporomandibular joint dysfunction. Several factors have been implicated in the literatures responsible for causing masseter spasm including use of non-depolarizing muscle relaxants, selective serotonin reuptake inhibitor and anxiety. Our case is the first to report masseter spasms with the use of Cis-atracurium in a patient on antidepressant depressant treatment with sertraline and having extreme preoperative anxiety. Anaesthesiologist should be aware of this complication when dealing with anxious patients on antidepressant therapy during induction of anaesthesia. Masseter spasm with locked jaw, can be a potential life-threatening situation particularly in scenarios of "cannot- ventilate-cannot intubate".

THANC (Thyroid, Head and Neck Cancer) Foundation, New York, New York, USA.
Tracheoesophageal puncture (TEP) with voice prosthesis (VP) placement is commonly used to restore voice in laryngectomy patients. The conventional procedure utilizes a rigid esophagoscope to open and visualize the pharyngeal inlet. However, this approach is challenging in patients with postradiation changes, reduced neck extension, or trismus.

Teerthanker Mahaveer University, Morādābād, India.
Background: It has been outlined that LTM (Lower third molar) extracted from patients in which grinding, cleaning, sterilization & demineralization prove to be highly effective as graft material for filling the alveolar socket of the very same patient. These investigations aim to assess the efficiency of ADDM (Autogenous Demineralized Dentin Matrix) graft in third molar extraction sockets.
Purpose: To check the effectiveness of ADDM as graft material in extraction socket by evaluating pain, swelling, trismus, PD (Probing Depth) and bone density.
Evaluation of the Low-Level Laser Therapy in Pain, Bite Force, and Mouth Opening Following Midfacial Trauma.

School of Dentistry, São Paulo State University, Araçatuba 16015-050, Brazil.
Low-level laser therapy (LLLT) is known for its biostimulant properties, which can reduce inflammation and promote tissue regeneration. The present study is randomized, blinded, and placebo-controlled and aims to investigate the role of LLLT in the postoperative recovery of facial fractures. Patients with fractures of the zygomatic bone are selected and divided into two groups: low-level laser and red placebo light.
