Improving Projection of the Nasal Tip in Primary Endonasal Rhinoplasty

Gaining, improving, and maintaining nasal tip projection is one of the most essential elements of successful endonasal rhinoplasty. For years the hallmark of inadequate nasal tip projection following rhinoplasty has been the Polly beak deformity. Early rhinoplasty technique consisted of intracartilaginous excision of the cephalic margin of the lower lateral cartilages, cartilage and bony hump reduction, and osteotomies. Some of these simple rhinoplasties still look good decades later, however, many are conspicuous in their lack of nasal tip projection. The reason for this inconsistency in rhinoplasty results was the surgeon's inattention to the structural integrity and anatomical position of the LLC. The senior author uses a combination of suture, strut, and cartilage grafting techniques to achieve ideal projection in a manor tailored to each patient's unique anatomic needs.

Investigation and sequence analysis of avian polyomavirus and psittacine beak and feather disease virus from companion birds in eastern Turkey

IntroductionAvian polyomavirus (APV) and psittacine beak and feather disease virus (PBFDV) induce contagious and persistent diseases that affect the beaks, feathers, and immune systems of companion birds. APV causes hepatitis, ascites, hydropericardium, depression, feather disorders, abdominal distension, and potentially death. PBFDV can induce progressive beak deformity, feather dystrophy, and plumage loss. We conducted the first prevalence survey of both APV and PBFDV infections in companion birds in eastern Turkey.Material and MethodsA total of 113 fresh dropping samples from apparently healthy companion birds were collected in a random selection. The dropping samples were analysed for PBFDV and APV by PCR. Positive samples were sequenced with the Sanger method. The sequence was confirmed through alignment and the phylogenetic tree generated through the maximum likelihood method computationally.ResultsPBFDV and APV were detected in a respective 48.7% and 23.0% of samples. Coinfection was found in 12.4% of the samples, these all being from budgerigars (Melopsittacus undulatus). APV and PBFDV were detected in budgerigar and cockatiel (Nymphicus hollandicus) samples.ConclusionThis report provides a foundation for future studies on the influence of these viruses on the health of companion birds. These high positive rates for both pathogens emphasise that healthy M. undulatus and N. hollandicus in eastern Turkey may be prone to the emergence and spread of APV and PBFDV with subclinical potential.

Does the Dog-Ear or Bird-Beak Deformity Remodel After Rotator Cuff Repair?

Background: Dog-ear and bird-beak deformities are common after transosseous-equivalent repair (suture bridge technique). The natural course of deformities after rotator cuff (RC) repair using the suture bridge technique is unclear. The remodeling potential of these deformities has not been investigated. Purpose: To evaluate remodeling and retear rates associated with deformities after RC repair. Study Design: Cohort study; Level of evidence, 3. Methods: Between November 2011 and February 2012, we studied 99 consecutive shoulders. All patients underwent arthroscopic RC repair via the suture bridge technique with or without additional sutures. Two groups were formed: no deformity (n= 46) and deformity (n = 53). Deformity was defined as marginal detachment and protrusion of the RC after repair, involving inappropriate compression of the suture limbs from the anchors. Tendon height was measured from the highest point of the most protruding portion of the cuff to the cortex on semi-coronal magnetic resonance imaging (MRI) scan. Change in tendon height was evaluated on MRI scan at 1 week and 6 months postoperatively. Clinical assessment at every patient visit included the American Shoulder and Elbow Surgeons (ASES) score, Constant shoulder score, and visual analog scale for pain (pVAS) score. Results: No significant differences were found in age, sex, symptom duration, tear size, and preoperative ASES, Constant, and pVAS scores ( P > .05) between the 2 groups. The initial tendon height was 7.4 ± 1.5 mm in the no-deformity group and 9.3 ± 2.0 mm in the deformity group. Follow-up height was 6.3 ± 2.1 mm in the no-deformity group and 6.4 ± 1.6 mm in the deformity group. Mean postoperative tendon heights were 90.1% ± 23.8% of the initial height in the no-deformity group and 73.2% ± 15.1% in the deformity group. Clinical scores (ASES, Constant, and pVAS) were not significantly different between the groups at 6 months. There were 4 shoulders in each group that experienced retearing (types 4 and 5 according to the Sugaya classification) at 6 months postoperatively. There was no difference in retear rate ( P > .999). Conclusion: Most deformities after RC repair were remodeled with no effect on retears. Clinical outcomes were not affected by deformities.

A case of beak deformity in the Shiny Cowbird Molothrus bonariensis and a review on beak deformities in wild birds in Brazil

Beak deformities in wild birds are rarely reported. Here, I described a case of beak deformity in Shiny Cowbird, Molothrus bonariensis, and also provide a review on beak deformities recorded in wild birds in Brazil. In October 2016, I observed a M. bonariensis with a grossly elongated maxilla in the east region of the Mato Grosso state, Brazil. The literature review revealed 60 records of beak deformities in the Brazilian avifauna. The most common types of deformity were crossed maxillae or mandibles (38%), probable accidental injuries (27%), and elongations (15%). Deformities were reported in 35 bird species of 22 families. The most affected species was Ramphastos toco with 21 records. The number of published reports from Brazil was low overall, and are not related as an epizootic episode recorded in some bird communities.
