Septal reconstruction

Nonsurgical rhinoplasty using filler injections is a popular procedure; however, it carries risks of significant complications, including vascular occlusion, skin necrosis, blindness, and cerebral ischemia. We present a case of septal necrosis after nonsurgical rhinoplasty and describe management using ultrasound guidance. Awareness of this complication and high clinical index of suspicion are necessary for early diagnosis and treatment, crucial to minimizing permanent sequelae. We show that high-definition ultrasound can help to guide the management and improve the treatment outcomes...

Background and Objectives: Skull base reconstruction is a crucial step during transsphenoidal surgery. Sphenoid mucosa is a mucosal membrane located in the sphenoid sinus. Preservation and lateral shifting of sphenoid mucosa as sphenoid mucosal flap (SMF) during the transsphenoidal exposure of the sella may be important for later closure. This is the first systematic review to evaluate the utility of sphenoid mucosal flap for sellar reconstruction after transsphenoidal surgery. Materials and Methods: A systematic literature search was performed in January 2023: Cochrane, EMBASE, PubMed, Scopus, and Web of Science...

Study Design: Technical note. Objective: The lower nasal architecture is dependent on caudal septal integrity. Deviations of the caudal septum can compromise nasal airflow. The presence of anterior nasal spine deviations contributes to septal and medial crural shifting with ipsilateral encroachment. It is essential to identify nasal spine deviation during surgery in order to reconstruct the septum in a midline position at its base. This allows an appropriate management plan that creates a better functional and aesthetically pleasing outcome...

Marsupials are born with structurally immature lungs when compared to eutherian mammals. The gray short-tailed opossum (Monodelphis domestica) is born at the late canalicular stage of lung development. Despite the high degree of immaturity, the lung is functioning as respiratory organ, however supported by the skin for gas exchange during the first postnatal days. Consequently, the majority of lung development takes place in ventilated functioning state during the postnatal period. Microcomputed tomography (μCT) was used to three-dimensionally reconstruct the terminal air spaces in order to reveal the timeline of lung morphogenesis...

INTRODUCTION: Asian nose is characterized by thick skin, abundant soft tissue, and weak cartilage framework, resulting in under-projection of the nasal dorsum and tip. Anatomical knowledge consideration is needed to achieve an ideal and natural-looking Asian nasal tip. Various nasal tip surgery techniques for Asian nose have been introduced recently. However, a comparison of techniques and postsurgical results has not yet been undertaken. OBJECTIVE: This systematic review aims to highlight the basic understanding of nasal tip dynamics aesthetic Asian nose and analyze related studies in search for the best technique and post-operative improvement for Asian tip-plasty...

BACKGROUND: Cartilage harvest and transplantation is a common surgery using costal, auricular, and septal cartilage for craniofacial reconstruction. However, absorption and warping of the cartilage grafts can occur due to inflammatory factors associated with wound healing. Transcription factor nuclear factor-κB (NF-κB) is activated by the various stimulation such as interleukin-1 (IL-1), and plays a central role in the transactivation of this inflammatory cytokine gene. Inhibition of NF-κB may have anti-inflammatory effects...

OBJECTIVES: To simulate cardiac malpositions, leftward and rightward shift and dextrocardia, and also to compare distribution of activity of septal and lateral walls of left ventricle acquired in standard acquisition arc and after relevant adjustment. METHODS: In this study, digital phantoms with cardiac malpositions are designed and procedure of acquisition of scan in standard arc (from right anterior oblique to left posterior oblique) and adjusted acquisition arc is simulated...

OBJECTIVE: To investigate the effectiveness of comprehensive rhinoplasty with autogenous costal cartilage grafting and prosthesis augmentation rhinoplasty in the treatment of secondary nasal deformity with saddle nasal deformity after cleft lip surgery. METHODS: The clinical data of 96 patients with secondary nasal deformity with saddle nasal deformity after cleft lip surgery between September 2008 and January 2019 were retrospectively analyzed. There were 17 males and 79 females with an average age of 25...

Alloplastic implants such as acellular dermal matrix (ADM) have been used for various aesthetic and reconstructive purposes since the 1990s. Rhinoplasty addresses both aesthetic and functional nasal impairments, often involving the adoption of grafting materials. Currently, autologous grafts, such as those using septal cartilage, are the gold standard. However, they pose the risk of donor site morbidity, technical challenges, and additional operative time. We review total complications, resorption/re-operation and success rates associated with the use of ADM in rhinoplasty...

BACKGROUND AND OBJECTIVES: The temporoparietal fascia (TPF) flap is an alternative for revision endoscopic skull base reconstruction in the absence of the nasoseptal flap, and we aimed to investigate the anatomy and surgical application of TPF flap transposition in endoscopic endonasal surgery. METHODS: Six lightly embalmed postmortem human heads and 30 computed tomography angiography imaging scans were used to analyze the anatomic features of the TPF flap transposition technique...

BACKGROUND: The clinical characteristics of pediatric nasal fractures can vary depending on the child's age, social activities, and environment. Therefore, this study aimed to analyze these characteristics in different age groups. METHODS: We retrospectively reviewed of a series of patients aged under 12 years who received treatment between 2013 and 2021. The initial study design involved dividing the patients into four age groups, corresponding to different developmental ages, but there were no cases in infants aged 0 to 1 year...

BACKGROUND: Several surgical techniques have been developed for the management of complex transposition of the great arteries with ventricular septal defect and left ventricular outflow tract obstruction (TGA/VSD/LVOTO). Aortic root translocation, or the Nikaidoh operation, offers the most anatomic biventricular repair in these patients. However, the Nikaidoh operation commonly has been limited to patients with "typical" anatomy, including a conoventricular VSD and usual coronary anatomy...

Congenital severe peripheral pulmonary artery stenosis is usually associated with pulmonary atresia, ventricular septal defect and major aortopulmonary collateral artery. Complications mainly related to respiratory system frequently occur after peripheral pulmonary artery patch augmentation with or without uniforcalization. Pulmonary hemorrhage and airway bleeding can be fatal. Airway compression from surrounding structures such as reconstructed central pulmonary artery, pulmonary hypertension, ventilation/perfusion mismatch, and pulmonary ischemia reperfusion injury are also life-threating complications...

<p>Airbag induced injuries such as skull and cervical spine fractures, epidural and subdural hematomas, atlantooccipital dislocations or brainstem lacerations are already documented in published literature, however, no previous case have been published about a penetrating foreign body of the skull base following airbag deployment. Removal of an intracranial foreign body is very dangerous and difficult, or even if it possible and necessary, requires open surgery in most of the cases. In this article we present the minimal invasive, transnasal removal of a coin from the intracranial, frontobasal region using high-resolution endoscopy combined with image-guided navigation...

BACKGROUND: Microform cleft lip is the mildest type of cleft lip without obvious defects of the upper lip. The nose deformities of microform cleft lip include flattened nostril rim, alar base asymmetry, and septal deviation. A hidden skin incision with nasal base muscle reconstruction was introduced in nose deformities of microform cleft lip. METHOD: To investigate the operative effect, we reviewed 21 patients with microform cleft lip treated with a hidden skin incision with nasal base muscle reconstruction from May 2020 to October 2022...

Spontaneous cerebrospinal fluid (CSF) leakage at the clivus is rare. In previous reports, reconstructive materials used to treat such leakage were typically autografts. Considering the pathology, rigid reconstruction is preferred. We here describe a case of spontaneous CSF leakage at the clivus with multiple bony defects. In this case, in addition to using artificial material instead of autografts, such as fat or fascia, that require additional extranasal invasive harvesting site, a rigid material layer of septal cartilage and bone was also used, enabling more stable multilayer reconstruction...
