Cranium bifidum occultum is a disorder of skull ossification presenting as an enlarged posterior fontanelle in the upper posterior angle of the parietal bone near the intersection of the sagittal and lambdoid sutures. The standard treatment for cranium bifidum occultum is observation. We present a case of a 5-year-old boy who presented with a 15x4.5 cm midline posterior cranial vault defect consistent with diagnosis of cranium bifidum occultum associated with orbital hypertelorism and a widened nose. The patient underwent posterior vault reconstruction for correction of cranium bifidum occultum defect followed by bifrontal craniotomy and orbital box osteotomies for correction of orbital hypertelorism and nasal deformity...

The aim was to evaluate the aesthetic and functional outcomes in patients with a nasal prosthesis after radical tumour resection. A questionnaire with 15 domains was created to evaluate the satisfaction of patients with their nasal prosthesis. Correlations with the results of the University of Washington Quality of Life (UWQOL) questionnaire, which was also completed by the patients, were analyzed. Forty-three patients with a partial or total nasal prosthesis completed the questionnaire. Twenty-seven patients were male and 16 were female; their median age was 62 years...

BACKGROUNDS: It has not been established whether sex differences in pain perception are influenced by prenatal sex hormones. Digit ratio as an indicator of prenatal hormone exposure can be used as a simple measure of the influence of prenatal hormones on pain sensitivity or perception in adulthood. OBJECTIVE: The aim of this study was to determine a correlation between the 2D:4D ratio and pain perception in the postoperative period after rhinoplasty. METHOD: A prospective cohort study of 100 patients (50 women of the mean age of 30...

A three-dimensional (3D)-printed customized bolus (3D bolus) can be used for radiotherapy application to irregular surfaces. However, bolus fabrication based on computed tomography (CT) scans is complicated and also delivers unwanted irradiation. Consequently, we fabricated a bolus using a 3D scanner and evaluated its efficacy. The head of an Alderson Rando phantom was scanned with a 3D scanner. The 3D surface data were exported and reconstructed with Geomagic Design X software. A 3D bolus of 5-mm thickness designed to fit onto the nose was printed with the use of rubber-like printing material, and a radiotherapy plan was developed...

Ectodermal dysplasia syndrome is a hereditary disease of ectodermal origin. Appearances of nail dystrophy, alopecia or hypotrichosis, saddle nose deformity, and palmoplantar hyperkeratosis are usually associated with a lack of sweat glands as well as partial or complete absence of teeth. These manifestations are usually corrected only with oral rehabilitation by mounting dentures. In this study, plastic rehabilitation was developed to correct the special features of patients with ectodermal dysplasia. Four men and 1 woman with ectodermal dysplasia syndrome were treated...

The risk of cancer is significantly increased in patients undergoing renal transplant surgery than in the general population. In particular, skin cancer is the most commonly occurring cancer in these patients.A 34-year-old man underwent living renal transplantation for focal segmental glomerulosclerosis. After 18 months, he developed a lesion on the nasal dorsum, approximately 1 cm in size, and the lesion rapidly expanded to cover the entire dorsum.Owing to its rapid expansion, the lesion was suspected to be a malignant tumor and wide excision was planned...

Sami P Moubayed, Sam P Most
By convention, a "deviated nose" is one in which the lower third is asymmetric with regard to the midline. The lower third of the nose is composed of the lower cartilages, as well as the dorsal and caudal nasal septum. Not only does the deviated nose cause a cosmetic deformity that is often disconcerting for patients, but it may also be associated with functional problems. Airway obstruction may result from a narrowed internal nasal valve in the middle third or from a deviated caudal septum in the lower third...

Pedro Redondo, Isabel Bernad, Ester Moreno, Marta Ivars
BACKGROUND: The typical reconstructive option for closing large-sized defects of the distal half of the nose is the paramedian forehead flap. Other alternatives are a melolabial interpolation flap and bilobed or trilobed flaps. The dorsal nasal (Rieger) flap is suitable for closing small-sized defects at this location, especially when they are medially located. OBJECTIVE: The authors describe a modified dorsal nasal flap reconstruction for large nasal defects. The novelty of this study lies in lengthening the leading edge of flap rotation, which may provide tissue either from the adjacent nasal skin, the nasofacial groove, or the cheek...

During forensic facial reconstruction, facial features may be predicted based on the parameters of the skull. This study evaluated the relationships between alar cartilage and piriform aperture and nose morphology and facial typology. Ninety-six cone beam computed tomography images of Brazilian subjects (49 males and 47 females) were used in this study. OsiriX software was used to perform the following measurements: nasal width, distance between alar base insertion points, lower width of the piriform aperture, and upper width of the piriform aperture...

BACKGROUND: Defects involving several aesthetic subunits (ASUs) or lying at the junction of an ASU are challenging and require a complex reconstruction. This study aimed to describe the hemi-tip as a new ASU. MATERIAL AND METHODS: We conducted a retrospective study including patients who underwent a nasal reconstruction for lower nasal pyramid defects according to our modified ASU principle. Patients who suffered from a subtotal alar defect, which also involved <50% of the tip, were reconstructed after excising the remaining tissue of the hemi-tip subunit...

E Querol-Cisneros, P Redondo
INTRODUCTION: The basic principle of a lobed or finger-like transposition flap is that, after covering the defect with the transposed tissue, the donor site is closed primarily. With large defects, a second lobe may be added to the flap if primary closure of the area left by the first lobe is not possible. The flap can often be made to adapt to the defect, but this maneuver, in combination with primary closure of the adjacent tissue, can sometimes produce excessive tension and compromise the blood supply...

Variations in skin thickness and contours pose significant challenges to reconstruction of the lower third of the nose. Human amniotic membrane allograft offers a potential alternative to tissue transfer in reconstruction of the lower third of the nose. We reviewed the procedure and photographs of a healthy 56-year-old male with a 22 × 18 mm lower third nasal defect involving full thickness skin and subcutaneous tissue. Following preparation for grafting, dehydrated human amniotic membrane was fashioned to the dimensions of the defect and applied...

Nasal deformity associated with typical cleft lip can cause aesthetic and functional issues that are difficult to address. The degree of secondary nasal deformity is based on the extent of the original cleft deformity, growth over time, and any prior surgical correction to the nose or lip. Repair and reconstruction of these deformities require comprehensive understanding of embryologic growth, the cleft anatomy, as well as meticulous surgical technique and using a spectrum of structural grafting. This article reviews cleft lip nasal deformity, presurgical care, primary cleft rhinoplasty, and definitive cleft septorhinoplasty with a focus on aesthetics and function...

The nose is the central organ of the face. It has two essential roles, aesthetic and breathing. It is often seriously damaged in the context of facial burns, causing grotesque facial disfigurement. As this disfigurement is visible on frontal and profile views, the patient suffers both socially and psychologically. The nose is a three-dimensional organ. Reconstruction is therefore more difficult and needs to be more precise than in other parts of the face. Maintaining symmetry, contour and function are essential for successful nasal reconstruction...

Nico Franz, Guanyang Zhang
BACKGROUND: Using syntactic and semantic conventions of the taxonomic concept approach (Franz et al. 2015), we describe three newly recognized fossil broad-nosed weevils (Coleoptera: Curculionidae: Entiminae) preserved in Early Miocene amber (ca. 20.4-16.0 mya) from the Dominican Republic: Scelianoma compactasp. n. sec. Franz & Zhang (2017) (henceforth abbreviated as [FZ2017]), Tropirhinus palpebratussp. n. [FZ2017], and Diaprepes anticussp. n. [FZ2017]. The taxonomic assignment of the amber inclusions is grounded in a preceding phylogenetic analysis by Franz (2012)...
