AbstractAim:To assess the clinical and radiological characteristics of the posterior prolongation of the cartilaginous nasal septum, an under-utilised source of autologous cartilage for nasal reconstruction.Materials and methods:Consecutive patients undergoing primary, external approach rhinoplasty were included. The septal cartilage was assessed intra-operatively prior to routine harvest. Cartilage use was recorded and post-operative cosmesis noted. Computed tomography scans from a separate patient group, with no septal surgery, were used to assess septal cartilage dimensions.Results:Of the 25 rhinoplasty patients studied, 24 had harvestable septal cartilage, with a posterior prolongation mean length ± standard deviation of 24.3 ± 8.40 mm, mean height of 4.33 ± 0.34 mm and mean width of 1.1 ± 0.35 mm. The mean post-operative cosmesis score was +2.41 ± 0.71 at a mean follow up of 45 ± 8.7 weeks. All 25 radiology patients had visible posterior prolongations on computed tomography (mean length, 18.1 ± 5.1 mm; mean height, 4.2 ± 1.1 mm; mean width 1.5 ± 0.63 mm).Conclusion:Harvesting of the posterior prolongation would increase by 25 per cent the cartilage area available for autologous grafts. Endoscopic guidance aids this process. Cartilage is most commonly used for overlay grafts, with good cosmesis. The posterior prolongation is demonstrated on computed tomography, although dimensions may be underestimated.

Introduction: Deviated nasal septum is one of the most common causes for the nasal obstruction. The objective of this study is to compare the surgical outcomes in patients undergoing conventional septoplasty and endoscopic septoplasty in the management of deviated nasal septum. Methods:  Prospective comparative study was conducted on 60 patients who presented to the Department of ENT, College of Medical sciences, during a period of one year. The severity of the symptoms was subjectively assessed using NOSE score and objectively assessed using modified Gertner plate. Results: There was significant improvement in functional outcome like NOSE Score and area over the Gertner plate among patients who underwent endoscopic septoplasty. Significant difference in incidence of post-operative nasal synechae and haemorrhage was seen in conventional group compared to endoscopic group. Conclusions: Endoscopic surgery is an evolutionary step towards solving the problems related to deviated nasal septum. It is safe, effective and conservative, alternative to conventional septal surgery.

Introduction: Septoplasty is a commonly performed surgical procedure worldwide in otorhinolaryngology. Septoplasty aims to correct the deviated nasal septum at the midline thereby opening the nasal airway in patients with long standing nasal obstruction secondary to septal deviation. Nasal breathing is important for proper facial growth and improvement of quality of life in children. Most surgeons are still reluctant to perform septoplasty in children. But septoplasty should be performed in children if there are severe breathing problems related to septal deviation. Objectives: The objectives of this study were to identify the incidence of children presenting with symptomatic nasal septal deviation and to analyze the early outcomes of septal surgery in children with regard to improvement in nasal symptoms, residual disease and need for revision surgery. Methodology: Children less than seventeen years of age who underwent septoplasty for symptomatic DNS from 1st January 2009 to 31st December 2018 were enrolled in the study. Patients having the follow up record of at least 6 months after surgery were included in the final analysis. Results: There were 37 male and 13 female children enrolled in the study. Male to female ratio was 2.84:1.Majority of children in the study were of 13 years (24%). Left sided DNS was seen in 28 children and right sided DNS in 22 children. Bleeding requiring re-packing, septal hematoma, recurrent DNS, synechia and septal perforation were the common complications, which were comparable to adult population. Conclusion: Early correction of the obstructed nose due to deviated nasal septum is essential to provide normal nasal breathing, relieve complications of mouth breathing and to promote normal craniofacial growth. Septoplasty can be performed in pediatric population with relatively good results without occurrence of nasal deformity and equal complications as that in adults.

Introduction The inferior turbinate (IT) is the most susceptible turbinate to enlargement causing nasal obstruction. The common belief ascribes most of the enlargement of the IT to mucosal elements. Objective This study aimed to investigate the detailed computed tomography (CT) measurement of the IT in asymptomatic adult by determining the thickness of both the non-bony (mucosa) and bony parts and their relation to nasal air space in different related areas of the nose. Methods We included in the study paranasal CT scans of 108 individuals (216 IT) that had no paranasal pathology. We acquired axial images with multiplanar reformates to obtain delicate details in coronal and sagittal planes for all subjects. We took separate measurements of the thickness of the medial mucosa, bones, and lateral mucosa of the IT on the anterior and posterior portions of ITs. We also measured the air space of the nasal cavity between the septum and IT anteriorly and posteriorly. Results The difference in the air space between nasal septum, anterior and posterior ends of IT was extremely statistically significant (P < 0.0001). The thickness of the medial mucosa was extremely significantly more than the lateral mucosa width (P < 0.0001). There was no significant difference in length of IT at both sides (p = 0.5781). Conclusion The detailed CT measurement of the IT in normal adult is an easy and novel measurement. This study lays the foundation for CT measurement of IT for further work that can describe changes in IT measures after turbinate surgery.

AbstractObjectives:This study was designed to investigate the effects of the tissue adhesive N-butyl cyanoacrylate on nasal septal tissues after septal surgery in a rabbit model.Methods:Forty-two adult New Zealand rabbits were randomly divided into three groups (14 in each group): septoplasty alone, septoplasty plus N-butyl cyanoacrylate, and controls. The open approach was used to explore the nasal septum. After raising mucoperichondrial and mucoperiosteal flaps on both sides of the septum, the septum was detached from the nasal floor in the septoplasty alone and septoplasty plus N-butyl cyanoacrylate groups. In the septoplasty plus N-butyl cyanoacrylate group, the mucoperichondrial and mucoperiosteal flaps were fixed to the septum and the septum was fixed lateral to the nasal spine using N-butyl cyanoacrylate; in the septoplasty alone group, the septum was packed with Merocel. In the control group, no further septal surgery was performed after flap elevation. Animals were observed for bleeding and haematoma formation over the first 24 hours. Seven animals in each group were used to evaluate early histopathological effects on the septal tissues, at four weeks post-operatively; the other seven in each group were used to evaluate late effects, at 12 weeks.Results:Haematoma formation was observed in 10 animals in the septoplasty alone group, in four animals in the control group, and in only one animal in the septoplasty plus N-butyl cyanoacrylate group. The difference in haematoma incidence between the septoplasty alone and the septoplasty plus N-butyl cyanoacrylate groups was significant (p = 0.000). Histopathological evaluation revealed no significant difference between the groups as regards granulation tissue formation at week four versus week 12; however, there was a significant difference between the septoplasty plus N-butyl cyanoacrylate group and the control groups as regards inflammation at week 12 (p = 0.038). There was a significant difference between the septoplasty plus N-butyl cyanoacrylate group and the septoplasty alone group as regards the composition of the bone–cartilage junction zone at week four (p = 0.001). There was also a significant difference between the septoplasty plus N-butyl cyanoacrylate group and the control group as regards the cellular structure of new cartilage formation at week 12 (p = 0.004).Conclusions:In this rabbit septoplasty model, N-butyl cyanoacrylate appeared to be an effective nasal tissue adhesive, with a low complication rate.

ABSTRACTMicro computed tomography has revealed as yet undescribed internal braincase anatomy of the tetrapodomorph fish Gogonasus andrewsae from the Frasnian Gogo Formation, Paddy's Valley, Kimberley Region, Western Australia. The complete material, including the cranial cavities and channels for blood vessels and nerves, reveals several notable features inside the endocranium. The ethmosphenoid unit includes a median capsule, which lies underneath the median postrostral and rostral series. Based on innervation and association with cutaneous vessels, potential electroreceptive function is inferred for this capsule. Several regions of poor ossification, including foramina for the glossopharyngeal and abducens nerves, as well as the apparent suture separating the ethmoid from the sphenoid portions of the braincase, are possibly indicative of early ontogenetic features. Former interpretations of the course for the superficial ophthalmic nerve inside the nasal capsule of Osteolepis and Gyroptychius may be incorrect, with new research supporting a path through the nasal septum, as in Gogonasus.
