- Identification of 2 Novel ANTXR2 Mutations in Patients With Hyaline Fibromatosis Syndrome and Proposal of a Modified Grading System(2012) DENADAI, Rafael; RAPOSO-AMARAL, Cassio E.; BERTOLA, Debora; KIM, Chong; ALONSO, Nivaldo; HART, Thomas; HAN, Sangwoo; STELINI, Rafael F.; BUZZO, Celso L.; RAPOSO-AMARAL, Cesar A.; HART, P. SuzanneJuvenile hyaline fibromatosis (JHF) and infantile systemic hyalinosis (ISH) are rare, autosomal recessive disorders of the connective tissue caused by mutations in the gene encoding the anthrax toxin receptor 2 protein (ANTXR2) located on chromosome 4q21. Characteristically, these conditions present with overlapping clinical features, such as nodules and/or pearly papules, gingival hyperplasia, flexion contractures of the joints, and osteolytic bone defects. The present report describes a pair of sibs and three other JHF/ISH patients whose diagnoses were based on typical clinical manifestations and confirmed by histopathologic analyses and/or molecular analysis. A comparison of ISH and JHF, additional thoughts about new terminology (hyaline fibromatosis syndrome) and a modified grading system are also included. (C) 2012 Wiley Periodicals, Inc.
- Transoral Submucosal Resection of the Inferior Turbinate A Novel Approach to Functional Rhinoplasty(2012) SINGH, Devinder P.; FORTE, Antonio J. V.; APOSTOLIDES, John G.; ZAHIRI, Hamid R.; STROMBERG, Jeffrey; ALONSO, Nivaldo; PERSING, John A.Background: In the presence of turbinate dysfunction, an inferior turbinectomy for persistent hypertrophy of bone and/or mucosa may be performed. We sought to explore anatomic feasibility of a transoral turbinectomy. Methods: After transoral inferior turbinectomy in 12 cadavers, average distances from the external nasal valve to inferior turbinate and from pyriform aperture to inferior turbinate were compared. Average ""area of access"" was calculated. Preoperative and postoperative nasal length, tip projection, and alar-base width were also compared. Results: Average distance from external nasal valve to inferior turbinate was 32.4 mm. Average distance from aperture to inferior turbinate was 2.4 mm (P < 0.0001). Average ""areas of access"" to nasal vault through the external nasal valve and mouth were 183.9 mm(2) and 243.6 mm(2) (P = 0.07), respectively. Conclusions: The transoral approach provides a larger ""area of access"" to the turbinate, a statistically significant reduction of distance to target, no postoperative changes in nasal soft tissue, and easier instrumentation.
