Using greater superficial petrosal nerve and geniculate ganglion as the only two landmarks for identifying internal auditory canal in middle fossa approach.
The middle fossa approach is a surgical technique indicated for acoustic neuroma with advantages of complete tumor removal and hearing preservation. Various methods have been developed for identifying internal auditory canal (IAC). Here, we describe a new method, which uses greater superficial petrosal nerve (GSPN) and geniculate ganglion (GG) as the only two landmarks to identify IAC. ⋯ We applied this method on 20 temporal bones by drilling the point away from the tip of the GG about 9.9 mm on a line angled with the GSPN about 96 degrees. All IACs were safely identified without damaging the cochlea, the labyrinthine portion of the facial nerve, or the vestibule. In conclusion, the GSPN and GG can be the only two landmarks for safely identifying the IAC without injury to the inner ear structures in the middle fossa approach.

Study of clinical treatment of esophageal foreign body-induced esophageal perforation with lethal complications.
Esophageal foreign body-induced esophageal perforation is a lethal complication and its treatment very complex. We had reviewed 1,428 patients with esophageal foreign body, who were hospitalized and treated over the past 25 years. A classification summary was made of 121 patients (of these 1,428 cases) who presented with esophageal foreign body-induced perforation and complicated cervical abscess, mediastinitis, and mediastinal abscess. ⋯ In the treatment of esophageal foreign body-induced severe complications, various therapies should be applied simultaneously. Lateral cervical incision should be made immediately to remove the foreign bodies if the foreign body extraction under esophagoscope proves to be a failure after repeated attempts, or esophageal perforation develops during the procedure, or should cervical abscess develop. Mediastinotomy and drainage or/and closed-chest drainage should be carried out as early as possible when mediastinitis and/or mediastinal abscess develops after esophageal foreign body ingestion.

Endoscopic skull base training using 3D printed models with pre-existing pathology.
Endoscopic base of skull surgery has been growing in acceptance in the recent past due to improvements in visualisation and micro instrumentation as well as the surgical maturing of early endoscopic skull base practitioners. Unfortunately, these demanding procedures have a steep learning curve. A physical simulation that is able to reproduce the complex anatomy of the anterior skull base provides very useful means of learning the necessary skills in a safe and effective environment. ⋯ The participants found the models suitable for learning registration, navigation and skull base drilling techniques. All participants also found the deep structures to be accurately represented spatially as confirmed by the navigation system. These models allow structured simulation to be conducted in a workshop environment where surgeons and trainees can practice to perform complex procedures in a controlled fashion under the supervision of experts.

Anti-cholinergic effect of singulair on isolated rat's tracheal smooth muscle.
Singulair (Montelukast) is a potent and selective leukotriene D(4) receptor antagonist, often used in treating inflammatory conditions of the respiratory system such as allergic rhinitis and asthma. However, the effects of singulair given intratracheally have rarely been well explored. To verify the effect of singulair, which acts on the tracheal smooth muscle directly in vitro. ⋯ Singulair could not inhibit electrical field stimulation-induced spike contraction. It also had a minimal effect on the basal tension of trachea as the concentration increased. This study showed that the high concentrations of singulair also had an anti-cholinergic effect for relieving symptoms of asthma.
