Radiological Study of the Ethmoidal Arteries in the Nasal Cavity and Its Pertinence to the Endoscopic Surgeon

Abstract

We studied the ethmoidal arteries using preexisting computer tomography of the paranasal sinuses (CT PNS) and statistically scrutinized data obtained between genders. A descriptive study from 77 CT PNS dated January 2016–December 2016 were collected and reviewed by two radiologists. A total of 54 (108 sides) CT PNS were studied of patients aged 18–77 years. 37 are male, 17 are female; with Bumiputera Sarawak predominance of 25 patients, 12 Malays, 16 Chinese and one Indian. Rate of identification are as follows: anterior ethmoidal artery (AEA)-100%, middle ethmoidal artery (MEA)-30%, posterior ethmoidal artery (PEA)-86%. The average distance from AEA–MEA is 8.1 ± 1.52 mm, MEA–PEA is 5.5 ± 1.29 mm and AEA–PEA is 12.9 ± 1.27 mm. The mean distance from PEA-the anterior wall of sphenoid is 7.7 ± 3.96 mm, and PEA-optic canal is 8.5 ± 3.1 mm with no statistical difference when compared between gender. AEA frequently presented with a long mesentery 57.4%, while 87.1% of PEA was hidden in a bony canal. The vertical distance of the AEA-skull base ranges from 0 to 12.5 mm whilst PEA-skull base is 0–4.7 mm. There is no statistical difference in distances of AEA, MEA nor PEA to skull base when analyzed between genders; t(82) = 1.663, p > 0.05, t(32) = 0.403, p > 0.05 and t(75) = 1.333, p > 0.05 respectively. We newly discovered, that 50% of MEA is hidden in a bony canal, and its distance to skull base ranged 0–5.3 mm. MEA and PEA less commonly have a short or long mesentery. Knowledge on the ethmoidal arteries especially in our unstudied population of diverse ethnicity, gains to assist surgeons worldwide, when embarking in endoscopic transnasal surgeries.

The molecular allergology of subtropical grass pollen

Grass pollens are amongst the most important aeroallergen sources world-wide triggering allergic rhinoconjunctivitis and asthma in sensitised patients. Much of what we know about the allergen components of grasses is informed by research on pollen of temperate (Pooideae) species that are abundant in the temperate climate zones. However, climate changes are altering the biogeographical distribution as well as timing and allergenicity of grass pollens. This provides an impetus for better understanding of the contribution of subtropical subfamilies of grasses to pollen allergy globally. Pollen of Chloridoideae (e.g. Cynodon dactylon; Bermuda grass) and Panicoideae (e.g. Paspalum notatum; Bahia grass or Sorghum halepense; Johnson grass) subfamilies are clinically important in subtropical zones of Australia, Asia, India, Africa, and America. These grasses differ ecologically and phylogenetically from temperate grasses and, importantly their allergen composition is qualitatively different. For example, subtropical grass pollens appear to lack the major group 5 grass pollen allergen family. In this review we summarize current knowledge of the epidemiology and immunology of subtropical Chloridoideae and Pancoideae pollen allergens, describe the biochemical characteristics of known isoforms and variants as well as properties and structures of subtropical pollen allergen components. Whilst only one subtropical allergen component; Cyn d 1 of Bermuda grass pollen, is available commercially for diagnostic use, in a natural purified form, a number of allergens of Panicoideae grass pollen; Zea m 1, Zea m 3 and Zea m 13 of maize, Pas n 1 and Pas n 13 of Bahia, as well as Sor h 1, Sor h 2, Sor h 13 and Sor h 23 of Johnson grass, have been discovered. Research effort is directed towards making available subtropical grass pollen allergen components as innovative treatment and diagnostic options that more specifically address the needs of patients from warmer regions of the globe.

The Revision Rhinoplasty Consult: The Art of Managing Expectations.

Facial plast Surg 2018; 34: 287-289
DOI: 10.1055/s-0038-1655734

Rhinoplasty is widely acknowledged to be a challenging operation. The success of the operation has long been measured in anecdotal ways. As the surgeon—do I think the outcome is good? Does the patient tell me they are happy? At hand is an obvious issue with patients sometimes not returning to their original doctor. Other times they may have minor concerns that take minimal effort to correct. Does that constitute a revision? In most circles, the ultimate definition of revision rhinoplasty is a return to surgery with the intent to correct a functional or aesthetic concern that arose after the original procedure.

Functional Compromise in the Middle Vault in the Management of Revision Rhinoplasty

Facial plast Surg 2018; 34: 239-244
DOI: 10.1055/s-0038-1654677

As rhinoplasty procedures become more common, the need for revision surgeries increases as well. Unlike primary rhinoplasties, revision rhinoplasties can be more challenging because of anatomic differences from initial surgery, a lack of available cartilage, tissue remodeling responses, and other complications. As such, surgeons should be prepared to address revision rhinoplasty patients differently from primary rhinoplasty patients. Here, the authors describe a generalizable approach to revision functional rhinoplasty patients and detail some of the surgical techniques that can be employed to achieve optimal outcomes, with particular attention paid to procedures that can be used in the middle vault.
