Blind nasal intubation has been one of the favoured methods of intubating the trachea in patients with restricted mouth opening and thus a difficult laryngoscopy and oro-tracheal intubation. Here, we describe airway management of patient who presented with traumatic ankylosis of the right temporomandibular joint and reduced mouth opening that was planned for elective release of the ankylosis an...

We report a successful treatment of bruxism in a patient with anoxic brain injury using botulinum toxin-A (BTX-A). On examination the mouth opening was 0 mm, no feeding was possible through the mouth. Botulinum toxin was injected into the masseter and temporalis; great improvement in trismus and bruxism was noted after 3 weeks. One further treatment improved the mouth opening on the following w...

Direction of mouth-opening of a small herbivorous Tanganyikan cichlid, Telmatochromis temporalis, was studied. Each sample fish opened its mouth either rightward or leftward in some degree. The directions of mouth-opening were independent of the body curve directions, and the asymmetry will be due to asymmetric mouth morph individually specific. The degree of the mouth asymmetry was not related...

Airway management of patients with very limited mouth opening remains a challenge for the anaesthetist. We describe the use of the Bonfils Intubation Fiberscope for awake intubation in two patients with a very limited mouth opening. In the first case, a 60-year-old 80 kg female, scheduled for a right modified radical mastectomy for infiltrating ductal carcinoma (15 mm mouth opening, a short thi...

In infants, eye constriction-the Duchenne marker-and mouth opening appear to index the intensity of both positive and negative facial expressions. We combined eye constriction and mouth opening that co-occurred with smiles and cry-faces (respectively, the prototypic expressions of infant joy and distress) to measure emotional expression intensity. Expression intensity and heart rate were measur...

[Purpose] This study investigated the effects of stomatognathic alignment exercise on temporomandibular joint function and swallowing function of stroke patients presenting limited mouth opening. [Subjects] Fourteen subjects with post-stroke hemiparesis presenting limited mouth opening were randomly assigned to either the experimental group or the control group, with 7 subjects in each group. [...

OBJECTIVE To assess rotation and translation movements of the mandible at maximum mouth opening in a group of patients successfully rehabilitated after condylar fractures. MATERIALS AND METHODS Using a three-dimensional motion analyser, free movements of mouth opening were recorded in nine patients, and divided into their rotation and gliding components. Surface electromyography (EMG) of the ...

Active and passive mouth opening exercises are a very common practice in oral and maxillofacial surgery especially for various conditions causing limited mouth opening like space infections, trauma, and ankylosis. But most of the practitioners do not follow basic principles while advocating these active mouth opening exercises and also take it for granted that it would benefit the patient in th...

The branch of Prosthodontics is not only a science but also an art of handling patients who present with limitations in continuing with normal procedures. An abnormally small mouth opening is called as microstomia. The common reasons for this condition include scleroderma, orofacial malignancies, surgery, burns and TMJ ankylosis. Impressions can be made for patients with restricted mouth openin...
