- Nasal patency after open rhinoplasty with spreader grafts(2012) POCHAT, Victor D. de; ALONSO, Nivaldo; MENDES, Rogerio R. S.; CUNHA, Marcelo S.; MENEZES, Jose V. L.Background: Spreader grafts have been used in cosmetic rhinoplasty, but little information is available about the objective results of treatment. This study sought to determine subjective and objective functional results of open cosmetic rhinoplasty with spreader grafts. Methods: Twenty patients (14 women, six men; mean age, 31 +/- 6 years) had open cosmetic rhinoplasty. Surgery included dissection of the upper lateral cartilages, from the septum, and placement of spreader grafts, symmetrically, along the dorsal edge of the septal cartilage. Preoperative and postoperative evaluation included breathing quality score, acoustic rhinometry and a modified Glatzel mirror test. Results: Evaluation after surgery (range, 5-18 months) showed significant improvement of breathing quality (before surgery, 8; after surgery, 9.4; P <= 0.001) and a mean minimal cross-sectional area of the left side (before surgery, 0.6 cm(2); after surgery, 0.9 cm(2); P <= 0.01). There was no significant change of the mean minimal cross-sectional area of the right side (acoustic rhinometry) or nasal patency (modified Glatzel mirror test) between preoperative and postoperative evaluation. Complications included postoperative synechiae in two patients and septal granuloma in one patient. Conclusions: Open structure rhinoplasty using spreader grafts is effective in reconstructing the internal nasal valve and preserving or improving nasal patency. Level of evidence: : IV (case series with preoperative and postoperative testing).
- Importance of early diagnosis of Stickler syndrome in newborns(2012) ANTUNES, Rodrigo Badotti; ALONSO, Nivaldo; PAULA, Raul GoncalvesObjective: The study aims to investigate a possible correlation between the main clinical and ophthalmological characteristics, age and Robin sequence in patients with the Stickler syndrome. Introduction: The Stickler syndrome is an autosomal dominant genetic disorder, characterised by ocular, orofacial and skeletal anomalies and/or auditory loss. Patients with Robin sequence features and respiratory complications are frequently diagnosed with the Stickler syndrome. The heterogeneous phenotypic manifestations may present a challenge for early clinical diagnosis. Methods: We performed a retrospective study of the 98 patients with the Stickler syndrome, between November 1995 and June 2009. The data were compared to investigate their ocular alterations and association with the Robin sequence. To be included, patients had to present with the following triad: cleft palate, facial features (hypoplastic midface, micrognathia and prominent eyes) and ocular anomalies (myopia and/or abnormalities of the retina). Results: Fifty-one percent of the patients presenting with Robin sequence features had been diagnosed with the Stickler syndrome. Ocular alterations were found in 50% of the patients. Discussion: The Robin sequence may appear as an isolated condition or associated with other features, or else as part of other known syndromes. Currently, the diagnosis of the Stickler syndrome is based on clinical signs. Affected individuals eventually develop hearing loss, retinal detachment and blindness. The ophthalmological complications associated are usually progressive and can lead to blindness.
