Postmortem Examination in Case of Asphyxial Death
Published in Sudhir K. Gupta, Forensic Pathology of Asphyxial Deaths, 2022
Alae and bridge of nose should be examined for any possible injuries. As a routine practice, nasal bridge should be examined by palpation. Nostrils should be evaluated in detail using nasal speculum. Mucosal injuries have to be evaluated in cases of suspected smothering. Blood stains (Figure 3.29), frothy fluids, regurgitated stomach contents, any foreign bodies, etc. have to be identified and documented. Adjacent cheeks have to be evaluated for any injuries externally.
Facial anatomy
Published in Michael Parker, Charlie James, Fundamentals for Cosmetic Practice, 2022
The nasal bones are paired bones which form the bony portion of the nasal bridge (Figure 3.5), found in the midline in the upper part of the face. The superior portion of the nasal bone is covered by the procerus and nasalis muscles. The nasal bones articulate with the frontal bone superiorly, the maxillae laterally and the ethmoid bones posteriorly. They are punctured at multiple sites by tiny foramina which allow for veins to exit the skull. Great care must therefore be taken when administering filler for non-surgical rhinoplasty due to the significant risk of venous ischaemia at this point.

Facial features may be mildly dysmorphic (Figures 102.6, 102.7, 102.13, and 102.14) [5, 7, 911, 13]. The facies of these patients tended to resemble each other. Some had epicanthal folds. In most, the nasal bridge was broad and depressed.

On physical examination, peculiar facial phenotype characterized by narrow, long face and a narrow and convex nasal bridge were noted. She was 160 cm in height and had an 88 cm inferior segment, a 72 superior segment and a 169 cm arm span: the upper to lower segment (US/LS) ratio was 0.82 and the arm span to height ratio was 1.056, both meeting the established Ghent II criteria for Marfan Syndrome (16). Other systemic features suggestive of Marfan syndrome were mild scoliosis and severe myopia, with no other skeletal or clinical features (e.g., joint hypermobility) suggestive of Marfan syndrome. Hands, ankle, wrist and chest X-ray as well as an abdominal ultrasound and echocardiogram were normal. Biochemical analysis were unremarkable. Her mother underwent complete physical examination and did not have any ocular or systemic features suggestive of either TS or Marfan syndrome. Her father was unavailable for clinical examination.

NCBRS often presents with a very distinctive set of facial features. The most commonly reported facial findings include thick/everted lower lip (n = 69, 83.5%), coarse facial features (n = 58, 77.3%), wide/large mouth (n = 59, 74.7%), thin upper lip (n = 59, 74.7%), thick/anteverted alae nasi (n = 57, 73.1%), low frontal hairline (n = 47, 62.7%), upturned nasal tip (n = 49, 62.0%), broad philtrum (n = 47, 59.5%), long philtrum (n = 44, 56.4%), broad nasal base (n = 42, 55.3%), and broad nasal tip (n = 39, 52.0%) (Table 2). Other common findings include sparse scalp hair (n = 76, 95.0%) and microcephaly (n = 37, 52.1%). Some less common features may have been underreported in past literature. Broad nose was reported in 31.6% (6/19) of cases and depressed nasal bridge was reported in 26.3% (5/19) of cases since 2015, whereas neither were reported in the prior 61 cases.
Exposure of Contralateral Eyes to Laser Radiation during Retinal Photocoagulation

We hypothesized that the bridge of the nose may have served as a protective barrier for the untreated eye. We further hypothesized that the nasal bridge protection might be lost in eyes with significant proptosis, where the globe extended past the nasal bridge. We repeated the experiments as above, this time directing the laser near the “untreated” sensor (Figure 1a,b). This would effectively eliminate any possibility of anatomic protection by the nasal bridge. Nonetheless, using the aforementioned standard settings, no laser exposure was detected in the untreated eye. With higher settings (700 mW), an exposure of 0.003315 ± 0.002176 µJ (range 0.001–0.00737 µJ, SD 95% CI 0.001513 to 0.004016 µJ) was measured and at the highest power (1000 mW), a mean exposure of 0.005254 ± 0.001324 µJ (range 0.00409–0.07 µJ, SD 95% CI 0.000910 to 0.00241 µJ) was detected. Based on our results, the nasal bridge only provides a minimal added barrier to laser exposure. It is likely that the untreated eye is protected simply by virtue of the absence of direct laser exposure, irrespective of the nose bridge.
