Pierre Robin Sequence: An Updated Evidence-Based Treatment Proposal.

Background: The Pierre Robin sequence (PRS) is characterized by the presence of micrognathia, glossoptosis, and respiratory obstruction during the neonatal period, its prompt recognition allows to mitigate the associated morbidity and mortality. A diagnosis and treatment algorithm was previously proposed based on data from the literature to guide therapeutic efforts; therefore, it was proposed to carry out a new search for relevant evidence to update or complement it.

Methods: A literature review of the subject was conducted in PubMed, Embase, and Cochrane databases, corresponding to the period between November 2016 and September 2021.

Keystone Flap: Overcoming Paradigms.

Background: The physiology and geometry of the keystone flap (KF) are the main factors that support its development. This study reports our experience using the KF and proposes the concept of pedicular area.

Methods: A prospective cohort study was conducted from October 2014 to December 2016, in which 112 KF procedures were performed with an average follow-up time of 10 months.

Neurofibroma of the Nasal Ala: Pediatric Nasal Reconstruction.

Benign tumors of the nasal cavity originating from a peripheral nerve sheath are rare. The authors present a case of a 3-month-old boy with a mass in the left nasal vestibule. The surgical resection was complicated by full-thickness necrosis of more than 50% of the nasal ala.

Pierre Robin Sequence: An Evidence-Based Treatment Proposal.

Background: The Pierre Robin sequence (PRS) has been defined as the presence of micrognathia, glossoptosis, and respiratory obstruction in the neonatal period. Since its original description, different therapeutic approaches have been proposed obtaining different success rates, but there is no consensus about its management.

Methods: A literature review was conducted in PubMed, Embase, and Cochrane databases, for the period of January,1985 to November, 2016.
