OBJECTIVE: Providing lasting cosmetic and functional results for patients with saddle nose deformity with allograft.
METHODS: This report describes experience with using a of freeze-dried allograft bone allograft in 58 patients who underwent dorsal augmentation over 5-year period (2018-2023). Thirty-eight patients had saddle-shaped deformity of the nose, and 16 patients had post-traumatic cases with saddle nose deformities. All patients underwent a clinical examination using computed tomography. Before surgery using a 3D model, the graft was contoured according to the shape of the nasal defect. The grafts were installed using a closed approach and were placed under the periosteum of the bone. Using lateral photographs, anthropometric measurements of the nose were taken before and after surgery to assess aesthetic outcome after surgery. To assess the results of aesthetic rhinoplasty (UQ), the Portuguese version of the Utrecht Questionnaire was used, which contains a visual analogue scale (VAS) on a 5-point Likert scale.
RESULTS: A total of 56 patients were satisfied with the results of the surgical procedure. No complications or major graft resorption was observed. An analysis comparing preoperative and 1-year follow-up data using 3D scanning showed a significant increase in dorsal height without dorsal expansion. After rhinoplasty, the mean visual analog scale (VAS) aesthetic score improved significant from 2.3 preoperatively, 3 months postoperatively 8.4, and 8.9 1 year postoperatively.
CONCLUSIONS: The use of freeze-dried allograft bone is a useful method of dorsal augmentation in rhinoplasty without donor site complications.

Crohn\'s disease is a chronic inflammatory disorder of the gastrointestinal tract, frequently presenting with extraintestinal manifestations. Granulomatosis with polyangiitis is a systemic vasculitis primarily affecting the respiratory tract and kidneys. Extraintestinal Crohn\'s disease and granulomatosis with polyangiitis may have similar clinical presentations and, in rare occurrences, can coexist. This case report highlights the diagnostic and therapeutic complexities of this uncommon overlap syndrome.

Relapsing polychondritis is an uncommon disorder of unknown cause characterized by inflammation of cartilage, predominantly affecting the ear, nose, and laryngotracheobronchial tree. The case under discussion is a 50-year-old female with a classical presentation of relapsing polychondritis with saddle nose deformity, bilateral auriculitis, and laryngotracheobronchomalacia with joint involvement.

Relapsing polychondritis (RP) is a rare autoimmune disease that can present with various clinical manifestations. Among the affected sites, the ear, nose, and throat cartilages are frequently involved, often leading to subtle and episodic symptoms that can be challenging to diagnose. A high index of suspicion is necessary for the early identification of these subtle signs, which can aid in early diagnosis and prompt management. In this report, we present a rare case of pediatric-onset relapsing polychondritis that was initially misdiagnosed as laryngotracheobronchitis.

Objective  The endoscopic endonasal approach (EEA) is commonly employed in skull base surgery for neoplasm resection. While nasal deformity following EEA is described, this study aimed to perform a detailed qualitative and quantitative assessment of the associated saddle nose deformity (SND) in particular. Setting/Participants  This is a retrospective review of 20 adult patients with SND after EEA for resection of skull base tumors over a 5-year period at the University of Pittsburgh Medical Center. Main Outcome Measures  Fifteen measurements related to SND were obtained on pre- and postoperative imaging. Statistical analyses were performed to evaluate differences between pre- and postoperative anatomies. Results  The most common EEA was transsellar. Reconstruction techniques included nine free mucosal grafts alone, eight vascularized nasoseptal flaps (NSFs), one combined free mucosal graft/abdominal fat graft, and one combined NSF/fascia lata graft. Imaging analysis showed a trend toward loss of mean nasal height, nasal tip projection, and nasolabial angle postoperatively. Subgroup analysis showed that patients with NSF reconstruction had a significantly decreased nasal tip projection (1.2 mm, p  = 0.039) and increased alar base width (1.2 mm, p  = 0.046) postoperatively. Patients without functional pituitary microadenomas demonstrated significantly increased nasofrontal angle and decreased nasal tip projection on postoperative imaging, in contrast to those with functional adenomas who had no measurable significant changes. Conclusion  Clinically evident SND does not always lead to significant radiographic changes. This analysis suggests that patients who undergo surgery for indications other than functional pituitary microadenomas or who receive NSF reconstruction develop more marked SND on standard imaging tests.

BACKGROUND: The workhorse for endonasal reconstruction of skull base defects is the posteriorly-based nasoseptal flap (NSF). Postoperative nasal deformities and decreased olfaction are potential complications of NSF. The reverse septal flap (RSF) minimizes the donor site morbidity of the NSF by covering the exposed cartilage of the anterior septum. Currently, there are minimal data examining its effect on outcomes including nasal dorsum collapse and olfaction.
OBJECTIVE: Our study aims to clarify whether the RSF should be utilized when the option exists.
METHODS: Adult patients undergoing endoscopic endonasal approach (EEA) surgery of the skull base (transsellar/transplanum/transclival approaches) with NSF reconstruction were identified. Data from 2 separate cohorts, one retrospective and one prospective, were collected. Follow-up was at least 6 months. Patients were photographed preoperatively and postoperatively using standard rhinoplastic nasal views. Patients completed the University of Pennsylvania Smell Identification Test (UPSIT) and the 22-item Sino-Nasal Outcome Test (SNOT-22) preoperatively and postoperatively and were also queried regarding subjective changes in nasal appearance and plans for cosmetic surgery following EEA.
RESULTS: There were no statistically significant differences in the change in UPSIT and SNOT-22 scores between patients receiving RSF and other reconstructive groups (either NSF without RSF or no NSF). One of 25 patients who were reconstructed with an NSF with RSF reported a change in nasal appearance; none were considering reconstructive surgery. The proportion of patients reporting changes in appearance was significantly lower in the NSF with RSF group as compared to the NSF without RSF group (P = .012).
CONCLUSIONS: The use of an RSF to limit donor site morbidity of the NSF was shown to significantly decrease the proportion of patients who reported nasal deformities and did not show a significant difference in patient-reported sinonasal outcomes. Given these findings, RSF should be considered whenever an NSF is used for reconstruction.

The subdorsal cantilever graft (SDCG) is a costal cartilage graft that is positioned below the nasal dorsum to control the position of the nasal bones and middle nasal vault. SDCG type A is used to raise the middle nasal vault and caudal nasal bones to correct the saddle nose deformity. SDCG type B can be used to raise the entire dorsum of the nose (radix, bony vault, and middle vault) in the ethnic augmentation rhinoplasty patient. This article will discuss the indications and technique of the SDCG in dorsal preservation rhinoplasty.

OBJECTIVE: To determine the time from initial injury to diagnosis of nasal septal hematoma (NSH). Additional objectives included determining number of medical evaluations prior to diagnosis and long-term complications.
METHODS: A retrospective chart review was performed on all patients diagnosed with NSH at a tertiary pediatric hospital between January 1, 2003 and April 1, 2019 were identified. Time to diagnosis was defined as time between initial trauma to date of diagnosis. Number of evaluations was defined as all medical evaluations prior to diagnosis.
RESULTS: Of 2762 charts that were reviewed, 13 patients with NSH were identified. Of those, 92% were male and trauma was the cause in 85% of patients. Median time to diagnosis was 7 days (0-21 days), with an average of 2.2 evaluations (1-4 evaluations). Settings where diagnosis were missed included EDs (N = 9, 82%), primary care (N = 6, 55%), urgent care (N = 1, 9%) and otolaryngology clinic (N = 2, 18%). Four patients (31%) were evaluated by an otolaryngologist in the ED. The median time to otolaryngology outpatient visit was 7.5 days. In five patients (46%), septal hematomas were missed in multiple clinical settings. Seven patients (54%) experienced complications, including saddle nose deformity (N = 3, 23%).
CONCLUSIONS: NSH is a rare but serious emergency. To avoid multiple visits and delay in diagnosis, additional education and awareness is needed for providers who evaluate these patients. Early diagnosis will reduce the risk of abscess formation and saddle nose deformity.

Granulomatosis with polyangiitis (GPA) causes a recurring inflammation in nose and paranasal sinuses that clinically resembles chronic rhinosinusitis (CRS) of other aetiologies. While sinonasal inflammation is not among the life-threatening features of GPA, patients report it to have major negative impact on quality of life. A relatively large proportion of GPA patients have severe CRS with extensive damage to nose and sinus structures evident by CT, but risk factors for severe CRS development remain largely unknown. In this study, we aimed to identify clinical and radiological predictors of CRS-related damage in GPA.
We included GPA patients who had clinical data sets from time of diagnosis, and two or more paranasal sinus CT scans obtained ≥12 months apart available for analysis. We defined time from first to last CT as the study observation period, and evaluated CRS development across this period using CT scores for inflammatory sinus bone thickening (osteitis), bone destructions, and sinus opacifications (here defined as mucosal disease). In logistic regression, we applied osteitis as main outcome measure for CRS-related damage.
We evaluated 697 CT scans obtained over median 5 years observation from 116 GPA patients. We found that 39% (45/116) of the GPA patients remained free from CRS damage across the study observation period, while 33% (38/116) had progressive damage. By end of observation, 32% (37/116) of the GPA patients had developed severe osteitis. We identified mucosal disease at baseline as a predictor for osteitis (odds ratio 1.33), and we found that renal involvement at baseline was less common in patients with severe osteitis at last CT (41%, 15/37) than in patients with no osteitis (60%, 27/45).
In this largely unselected GPA patient cohort, baseline sinus mucosal disease associated with CRS-related damage, as measured by osteitis at the end of follow-up. We found no significant association with clinical factors, but the data set indicated an inverse relationship between renal involvement and severe sinonasal affliction.
