Robin sequence: A retrospective review of 115 patients

Objectives: Review a large series of patients with Robin sequence to document the incidence of (1) associated syndromic diagnoses; (2) co-morbid conditions; (3) frequency and type of operative management for airway compromise and feeding difficulties; and (4) possible differences in treatment between syndromic and non-syndromic infants. Methods: Retrospective case-review of 115 patients with Robin sequence managed between 1962 and 2002 at two tertiary-care teaching hospitals for evaluation of demographic information, clinical findings, and treatment interventions. Results: Fifty-four percent (N = 63) of patients were nonsyndromic. Syndromic patients included: Stickler syndrome (18%), velocardiofacial syndrome (N), Treacher-Collins (5%), facial and hemifacial microsomia (3%), and other defined (3.5%) and undefined (9%) disorders. There was no statistical difference between the syndromic and nonsyndromic patients with regard to need for operative airway management (Fisher's exact test, p = 0.264). Forty-two percent of patients required a feeding gastrostomy tube to correct feeding difficulties. Patients with a syndromic diagnosis were more likely to be developmentally delayed. Fifty-one (44%) patients underwent operative airway management: 61% underwent tongue-lip adhesion and 39% underwent tracheotomy. Fifteen percent of patients initially had tongue-tip adhesion subsequently required tracheotomy. While the preferred treatment for respiratory compromise differed between the two institutions, the percentage of patients requiring operative intervention was similar. Conclusions: The pathogenesis of Robin sequence is multifactorial and syndromic in nearly half of the patients. Operative treatment of respiratory failure was required in 44% of infants; the rate was similar in both hospitals. The operative approach differed significantly between the institutions, however, based on the philosophy and training of the managing surgical specialty. Co-morbid factors such as baseline cardiopulmonary and neurologic status did not play a significant role in surgical decision making. (C) 2005 Elsevier Ireland Ltd. All rights reserved.
