Surgical Resection of Nasal Chondroma via open Rhinoplasty Approach: A rare case Presentation and Review of Literature.

ABSTRACT: Chondromas are benign tumors composed of mature hyaline cartilage tissue with well-defined boundaries that are commonly localised in the extremities with very few cases described in the head and neck region. We present a case of 57-year-old patient who consulted a specialist for an examination due to a change in the tip of the nose that persisted for the past 2 years. The clinical exam revealed a firm, tumor-altered tip of the nasal pyramid, with hyperemia of the skin above the mass. Biopsy was taken under local anesthesia; the histopathology analysis indicated a mesenchymal tumor producing the chondroid matrix suggestive of nasal type chondroma. Computerized tomography showed an ovoid, moderately inhomogeneous, sharply limited formation measuring 21 × 18 × 24 mm present mediosagitally at the top of the nasal pyramid. After preoperative preparation, the surgery was performed by open rhinoplasty approach. Tumor was completely excised with reconstruction of nasal septum and alar cartilage.

Project description:ImportanceThere is no imaging standard to model nasal cartilage for the planning of rhinoplasty procedures. Preoperative visualization of cartilage may improve objective evaluation of nasal deformities, surgical planning, and surgical reconstruction.ObjectivesTo evaluate the feasibility of visualizing nasal cartilage using high resolution micro-computed tomography (CT) compared with the criterion standard of pathologic findings in a cadaveric specimen and to evaluate its accuracy compared with various clinical CT protocols.Design, setting, and participantsAnatomic study at the University of Washington using single human cadaveric nasal specimens performed from July 10, 2017, to March 30, 2018.InterventionsA micro-CT acquisition with 60-micron resolution was obtained of a nasal specimen. The specimen was then scanned with 5 different clinical CT protocols to span both clinical care and machine limits. The specimen was then sectioned in 5-mm axial slices for pathologic analysis.Main outcomes and measuresMicro-CT images were registered to pathologic specimen cross-sections using a graphite fiducial system. Cartilage substructures were manually segmented and analyzed. A library of matched images across the micro-CT and various clinical CT protocols was then developed. Region of interest analysis was performed for each of the cartilage structures and their boundaries on clinical CT protocols and micro-CT, with the outcome of mean (SD) density using Hounsfield units.ResultsA single human cadaveric nasal specimen was used to obtain the following results. Lower lateral cartilage, upper lateral cartilage, and septal cartilage were accurately delineated on the micro-CT images compared with pathologic findings. The mean absolute deviation from pathologic findings was 0.30 mm for septal cartilage thickness, 0.98 mm for maximal upper lateral cartilage length, and 1.40 mm for maximal lower lateral cartilage length. On clinical CT protocols, only septal cartilage was well discriminated from boundary. Higher radiation dose resulted in more accurate density measurements of cartilage, but it did not ultimately improve ability to discriminate cartilage.Conclusions and relevanceThe results of this anatomic study may represent a notable step toward advancing knowledge of the capabilities and pitfalls of nasal cartilage visualization on CT. Nasal cartilage visualization was feasible on the micro-CT compared with pathologic findings. Future research may further examine the barriers to accurately visualizing upper lateral cartilage and lower lateral cartilage, a prerequisite for clinical application.Level of evidenceNA.

Project description:ImportanceThe social perception of nasal dorsal modification for male rhinoplasty is poorly understood.ObjectiveTo investigate the association of modifying the male nasal dorsum with the perception of such social attributes as youth, approachability, healthiness, masculinity/femininity, intelligence, successfulness, and leadership.Design, setting, and participantsUsing computer simulation software, 12 images with varied combinations of the nasal dorsal shape, nasofrontal angle (NFA), and nasolabial angle (NLA) were generated from a photograph of a male volunteer's face in profile. These photographs were then sent to participants at a university clinic who were English-speaking adult internet users who were masked to the purpose of the study, which asked them to value different social attributes regarding the face in the photograph in a 16-question survey. The study was conducted in September 2018 and the data were analyzed thereafter until March 2019.ExposuresTwelve photographs embedded in a 16-question survey.Main outcomes and measuresPopulation proportions of responses and χ2 test and graphical analysis based on 95% confidence intervals.ResultsOf 503 respondents (survey provision rate, 100%), 412 (81.9%) were women, 386 (76.7%) were white, 32 (6.4%) were Hispanic or Latinx, 63 (12.5%) were black/African American, 10 (2.0%) were Asian/Pacific Islander, and the median age was 46 years (interquartile range, 32-61 years). The man with ski slope-shaped nose with an NFA of 130° and NLA of 97° was often associated with frequently perceived positive characteristics; specifically, he was judged to be the most attractive (95% CI, 18%-26%; P < .001). Participants also often associated superlative youth (95% CI, 15%-24%; P < .001), approachability (95% CI, 13%-20%; P = .002), and femininity (95% CI, 14%-22%; P < .001) with dorsal contours that did not feature a dorsal hump. The man with a dorsal hump-shaped nose with an NFA of 140° and NLA of 105° was associated by the highest proportion of participants with being the oldest (95% CI, 35%-44%; P < .001), least approachable (95% CI, 27%-35%; P < .001), least attractive (95% CI, 37%-42%; P < .001), and least healthy (95% CI, 26%-34%; P < .001). Subset analyses also revealed statistically significant dorsal contour preferences by observers' age, gender, and race/ethnicity.Conclusions and relevanceA reduced dorsal slope combined with more acute NFAs and NLAs was associated with positively perceived social attributes. The results may be of interest to rhinoplasty surgeons and their male patients when planning changes to the nasal dorsal contour.Level of evidenceNA.
