Patients with an angle at Shaffer grade 3 or above (open) showed an average intraocular pressure reduction of 37% reduction one year after trabectome surgery, and of 25% reduction one year after phaco-trabectome. These results suggest that trabectome surgery is a viable option for patients with narrow angles [15]
Jaw reduction or mandible angle reduction is a type of surgery to narrow the lower one-third of the face—particularly the contribution from the mandible and its muscular attachments. There are several techniques for treatment—including surgical and non-surgical methods.
Mandibular setback surgery is a surgical procedure performed along the occlusal plane to prevent bite opening on the anterior or posterior teeth and retract the lower jaw for both functional and aesthetic effects in patients with mandibular prognathism. [1] [2] It is an orthodontic surgery that is a form of reconstructive plastic surgery. [3]
The length and angle of each flap are usually the same to avoid mismatched flaps that may be difficult to close. Some possible complications of Z-plasty include flap necrosis , haematoma (blood clot) formation under the flaps, wound infection, trapdoor effect and sloughing (necrosis) of the flap caused by wound tension and inadequate blood supply.
Palatal expander in mixed dentition. Rapid palatal expansion (RPE) or Rapid Maxillary Expansion (RME) is an expansion technique where expansion of 0.5 mm to 1 mm is achieved each day until the posterior crossbite is relieved.
SARPE is performed to address the transverse dimension changes in a patient. Sometimes this surgery is followed by Le Fort 1 in a second surgery to address the vertical and the anterior-posterior changes. Between the two surgeries, a patient's constricted maxillary arch is expanded with the rapid maxillary expander device placed in the maxilla.

In 1971, Fearon and Ellis described a child with severe subglottic stenosis who, after failed dilatations and anterior cricoid split with auricular cartilage graft augmentation, eventually underwent tracheotomy, placement of an anterior costal cartilage graft with buccal mucosa and a stent and was eventually decannulated.
