Assessing the ability of children and parents to rate their nasal patency. A cross sectional study.

Objective: Nasal obstruction is a common complaint in pediatric otolaryngology. There are several concerns about how nasal obstruction should be measured. This debate is even more important in children, as they can experience difficulties in being sensitive to their symptoms or even expressing them.

Application of 3D printing in the treatment of appendicular skeleton fractures: Systematic review and meta-analysis.

The objective of this study is to evaluate, through a systematic review of the scientific literature and meta-analysis, the applications of three-dimensional (3D) printing in the surgical treatment of complex fractures of the appendicular skeleton, mainly in terms of effectiveness and safety. A systematic review of the scientific literature was conducted in MEDLINE (PubMed) and the Cochrane Library combining different keywords. A specific methodological assessment scale was developed and applied to included papers.

Polymethyl Methacrylate Custom-Made Prosthesis: A Novel Three-Dimension Printing-Aided Fabrication Technique for Cranial and/or Orbital Reconstruction.

Background: Over the years, many materials have been used in orbital reconstruction and cranioplasty. Among the materials in current use, polymethyl methacrylate (PMMA) offers a high degree of compatibility with human tissue.

Objective: This work describes a new, custom-made, 3D printing-aided, prosthetic fabrication process for orbital and/or cranial reconstruction using PMMA.

Piezosurgery for Treatment of Large Recurrent Mandibular Osteoma.

Background: Osteomas are infrequent benign bone tumors of uncertain etiology. They are usually situated at extremities and their occurrence in the jaws is relatively rare. There are 3 types of osteoma: central, peripheral, and extraskeletal.
