Choanal atresia (CA) is a rare, congenital malformation resulting as a failure incommunication between the posterior nasal cavity and the nasopharynx. The clinical course isoften asymptomatic in unilateral CA leading to higher rates of misdiagnosis, in comparison tobilateral CA, which manifests itself as a surgical emergency at birth. Most cases present asisolated malformations, but it may also be associated with other congenital anomalies in 20-50%of cases. Currently, the most important diagnostic tool for CA is computerized tomography (CT)and confirmatory diagnosis is usually achieved with the help of nasoendoscopic examination.Although, different surgical approaches have been used in the past, transnasal endoscopicrepair is currently preferred over others. Herein, we describe our experience of three cases andshare our simple stentless endoscopic technique, to facilitate physicians working in low facilityunits for a timely diagnosis and prompt treatment.

Although the most common form of nasal obstruction in neonates is soft tissue edema, congenital bony nasal deformities are being recognized as an important cause of newborn airway obstruction. In addition to the well described choanal atresia, CT imaging of the newborn in respiratory distress reveals two other forms of bony nasal cavity deformities: nasal pyriform aperture stenosis and nasal cavity stenosis. All of the three types of bony nasal cavity deformities have characteristic anatomical features, are associated with distinctive congenital anomalies, and are postulated to have differing embryological causes. Five patients with congenital bony nasal cavity deformities are presented. These cases illustrate the clinical and radiological presentation of varied types of congenital nasal cavity obstruction as well as the criteria used to guide clinical management.

Latar belakang: Atresia koana adalah tertutupnya satu atau kedua posterior kavum nasi oleh membranabnormal atau tulang. Hal ini dapat terjadi bersamaan dengan kelainan kongenital lainnya. Atresia koanabilateral menyebabkan keadaan darurat pada saat kelahiran. Angka kejadian atresia koana adalah 1 kasus per5000 - 8000 kelahiran. Kejadian pada perempuan dua kali lebih banyak daripada laki-laki. Tujuan: Membahassatu kasus bayi dengan atresia koana bilateral yang didiagnosis di ruang operasi, yang tidak terdeteksisebelumnya karena adanya meningosil. Kasus: Bayi perempuan 16 hari dengan meningosil dan atresia koanabilateral. Penatalaksanaan: Pasien menjalani koanoplasti transnasal dan pemasangan stent. Pasien sembuhdengan baik. Kesimpulan: Atresia koana dapat terjadi bersama dengan kelainan kongenital lainnya, sehinggamemerlukan pemeriksaan yang teliti karena atresia koana bilateral menyebabkan keadaan darurat danmemerlukan penanganan segera.Kata kunci : atresia koana, koanoplasti, stent.ABSTRACTBackground: Choanal atresia is a condition where one or both posterior nasal cavity is blocked byabnormal bony or soft tissue. This condition can occur concomitant with other congenital anomalies. Bilateralchoanal atresia causes emergency situation at birth. The incidence of choanal atresia is one case per 5000-8000births and are twice as much in females. Purpose: To discuss a case of bilateral choanal atresia which wasdiagnosed in the operating theatre, undetected previously because of the meningocele. Case: A baby girl 16 daysold with meningocele and bilateral choanal atresia. Management: The patient underwent transnasalchoanoplasty and stenting. The result was satisfactory. Conclusion: Choanal atresia can occure with othercongenital abnormalities, so careful examination is mandatory as bilateral choanal atresia needs promptmanagement.Keywords : choanal atresia, choanoplasty, stent

Bilateral choanal atresia (CA) is a rare congenital malformation frequently associated with other anomalies. CHARGE association is closely linked to bilateral CA. The aim of this study was to describe the outcomes of the endoscopic repair in bilateral CA, and to assess the role of postoperative nasal stenting in two cohorts of CHARGE-associated and non-syndromic CA. Thirty-nine children were retrospectively analyzed (16 patients had CHARGE-associated CA). The rate of postoperative neochoanal restenosis was 31.3% in the CHARGE population, and 47.8% in the non-syndromic CA cohort. Data on postoperative synechiae and granulation tissue formation, need for endonasal toilette and dilation procedures, and number of procedures per patient were presented. Stent positioning led to a higher number of postoperative dilation procedures per patient in the non-syndromic cohort (p = 0.018), and to a higher rate of restenosis both in the CHARGE-associated, and non-syndromic CA populations. Children with CHARGE-associated and non-syndromic bilateral CA benefitted from endonasal endoscopic CA correction. The postoperative application of an endonasal stent should be carefully evaluated.

Qualitative features of the secondary xylem of Licaria present a rather uniform structural profile. Constant differences in primarily quantitative characters lead to the formation of speeies groups wh ich loosely correspond to infrageneric sections based on floral and vegetative morphology. This subdivision is strongly corroborated by the highly variable secondary phloem structurc revealing considerable diversity in type and distribution of sc1erenchymatic tissues. Inorganic inclusions in the secondary xylem, crystals and silica, constitute an important diagnostic tool for differentiating certain species and species groups, but are hardly of importance in the bark.

A variety of surgical approaches exists for the management of nasal septal spurs in patients who undergo endoscopic sinus surgery (ESS). Treatment of septal spurs in the past has been frequently addressed by septoplasty which can result in increased bleeding and length of surgical procedure as well as mandate postoperative nasal packing. Individually each of these problems can jeopardize the success of endoscopic sinus surgery. An endoscopic approach, which targets the septal spur alone, can minimize perioperative morbidity. The purpose of this paper is to demonstrate the effectiveness of endoscopic septal spur resection (ESSR) for the management of significant septal spurs in 8 patients who underwent concurrent ESSR during ESS for chronic sinusitis. Surgical technique and postoperative results are discussed and suggest that ESSR is a valuable alternative to more traditional techniques.

Abstract Dural arteriovenous fistulas are abnormal connections of dural arteries to dural veins or venous sinuses originating from within the dural leaflets. They are usually located near or within the wall of a dural venous sinus that is frequently obstructed or stenosed. The dural fistula sac is contained within the dural leaflets, and drainage can be via a dural sinus or retrograde through cortical veins (leptomeningeal drainage). Dural arteriovenous fistulas can occur at any dural sinus but are found most frequently at the cavernous or transverse sinus. Leptomeningeal venous drainage can lead to venous hypertension and intracranial hemorrhage. The various treatment options include transarterial and transvenous embolization, stereotactic radiosurgery, and open surgery. Although many of the advances in dural arteriovenous fistula treatment have occurred in the endovascular arena, open microsurgical advances in the past decade have primarily been in the tools available to the surgeon. Improvements in microsurgical and skull base approaches have allowed surgeons to approach and obliterate fistulas with little or no retraction of the brain. Image-guided systems have also allowed better localization and more efficient approaches. A better understanding of the need to simply obliterate the venous drainage at the site of the fistula has eliminated the riskier resections of the past. Finally, the use of intraoperative angiography or indocyanine green videoangiography confirms the complete disconnection of fistula while the patient is still on the operating room table, preventing reoperation for residual fistulas.

Динамика и уровень перинатальной смертности за последние десятилетие свидетельствовали о том, что в г. Алматы имеет устойчивую тенденцию к снижению до 8,8‰ к 2019 году. В структуре перинатальной смертности большая часть приходится на антенатальную (5,5-6,5‰); около трети - на раннюю неонатальную смертность (3,2 до 2,3‰). В структуре причин неонатальных потерь наблюдалось устойчивое снижение дыхательных и сердечно-сосудистых нарушений в 2,3-3,8 раза - с 5 до 1,3‰, врожденных аномалий с 4,4 до 0,9‰, неонатальные потери от инфекционных болезней остаются стабильными. Сохраняющие риски инфекционной патологии, особенно в беспрецедентной ситуации в период пандемии диктуют необходимость пересмотра подходов к оказанию перинатальной помощи населению и разработкой новой концепции перинатальной помощи с существенными изменениями в подходах инфекционного контроля, развития превентивной перинатологии с более эффективной антенатальной охраной здоровья плода. The dynamics and level of perinatal mortality over the past decade testified to the fact that in Almaty it has a steady downward trend to 8.8 ‰ by 2019. In the structure of perinatal mortality, most of it falls on antenatal (5.5-6.5 ‰); about a third - for early neonatal mortality (3.2 to 2.3 ‰). In the structure of the causes of neonatal losses, there was a steady decrease in respiratory and cardiovascular disorders by 2.3-3.8 times - from 5 to 1.3 ‰, congenital anomalies from 4.4 to 0.9 ‰, neonatal losses from infectious diseases remain stable. The persisting risks of infectious pathology, especially in an unprecedented situation during a pandemic, dictate the need to revise approaches to providing perinatal care to the population and develop a new concept of perinatal care with significant changes in approaches to infection control, thedevelopment of preventive perinatology with more effective antenatal fetal health care.
