Age-Related Histologic and Biochemical Changes in Auricular and Nasal Cartilages.

OBJECTIVE: Analyze age-related changes in histologic features and biochemical properties of human auricular cartilage and two subsites of nasal cartilages (quadrangular cartilage and dorsal septal articulation with upper lateral cartilages). STUDY DESIGN: Prospective cross-sectional study of nasal and auricular cartilages from seventy-three (73) live donors. METHODS: Auricular cartilage (AC), quadrangular cartilage (QC), and dorsal septal cartilage articulation (DSA) with the upper lateral cartilage (ULCs) were collected intraoperatively. Histochemical staining was used: Safranin O for glycosaminoglycans (GAGs), Verhoeff's for elastin, and Masson's trichrome for collagen. ImageJ2 software was used to calculate cell count and percent stained for each cartilage type. R studio "ggplot" package was used to visualize age versus cell count or percent stained. RESULTS: Participant ages ranged from 20 to 77 years, average 46.5 years. There was a significant decline in GAGs with age for the DSA subsite, (n = 64, p < 0.001). Significant increase in collagen content with age was observed for DSA subsite (n = 66, p < 0.001) and the QC subsite (n = 64, p < 0.05). There was a statistically insignificant decline in elastin with age (n = 41, p = 0.309) for AC. Cell count declined with age at all cartilage subsites. CONCLUSION: Our findings confirm that there were age-related decreases in cartilage glycosaminoglycan content, and chondrocyte cell count in both auricular and nasal cartilages. We have also confirmed that collagen content increases with age for both auricular and nasal cartilage. The histologic findings while not statistically significant in all comparisons, provides additional evidence that there is some loss of structural integrity and flexibility in nasal and auricular cartilage with aging.

Finite Element Analysis of the Septal Cartilage L-Strut.

Importance: Septoplasty is one of the most commonly performed operations in the head and neck. However, the reasons for septoplasty failure and the additional stress of performing a chondrotomy on the septal cartilage are not well understood. Design, Setting, and Participants: A finite element model of the nasal septum was created using a microcomputed tomography scan of the nasoseptal complex that was reconstructed into a three-dimensional model in silico. Testing included four common chondrotomy designs: traditional L-strut, double-cornered chondrotomy (DCC), curved L-strut, and the C-curve. Tip displacement was applied in a vector parallel to the caudal strut to simulate nasal tip palpation. Main Outcomes and Measures: With finite element analysis, the maximum principal stress (MPS), von Mises stress (VMS), harvested cartilage volume, and surface area were recorded. Results: The highest MPS for the L-strut, DCC, curved L-strut, and C-curve was identified at the corner of the chondrotomy. The MPS at the corner of the chondrotomy was reduced 44% when comparing the C-curve with the traditional L-strut. The VMS patterns showed compressive stress along the caudal septum in all models, but at the corner, the stresses were highest in the chondrotomies designed with sharp-angled corners. The VMS showed a 76% decrease when comparing the C-curve with the traditional L-strut. The stress across the anterior septal angle is also higher in models with sharp-angled corners. Cartilage harvest volumetric and surface area assessments did not show meaningful differences between shapes. Conclusions and Relevance: The highest area of stress is near the transition of the dorsal to caudal septum in all models. Stresses are relatively higher in chondrotomy shapes that contain sharp-angled corners. The relative reduction in MPS and VMS utilizing a C-curve instead of an L-strut may decrease the likelihood that the septum will deform or fail in this region. The volume and surface area of the C-curve are similar to that of the L-strut technique. Avoiding sharp-angled corners reduces the stresses at the corner of the chondrotomy and across the anterior septal angle. Using a C-curve may be an improved septoplasty design.

Using Digital Profileplasty for Surgical Planning.

This paper describes a method for setting up an automated and reliable digital profileplasty technique for use in Adobe Photoshop. Digital imaging software can be used to extrapolate more exact measurements during profileplasty. The digital profileplasty technique is helpful to provide intraoperative guidance during surgery.

How Patient Decision-Making Characteristics Affect Satisfaction in Facial Plastic Surgery: A Prospective Pilot Study.

BACKGROUND: The main objective of this study was to prospectively analyze which personality traits, clinical psychiatric states, and patient decision-making characteristics predict who will be less satisfied after facial plastic surgery. METHODS: This prospective study enrolled 60 adult subjects into one of three groups: aesthetic, functional, and reconstructive facial plastic surgery procedures (n = 20 in each group) from November of 2011 to February of 2016. Self-report surveys of personality traits (i.e., NEO Personality Inventory-Revised), psychiatric state (i.e., Patient Health Questionnaire, Generalized Anxiety Disorder, Health Anxiety Inventory-Short Form), and decision-making characteristics (maximizer/satisficer survey) were given during the preoperative clinic visits. In postoperative follow-up, satisfaction questionnaires at 3, 6, and 12 months were administered. Data analysis examined associations between patient satisfaction, decision-making characteristics, and psychiatric variables. RESULTS: Bivariate analyses showed that maximizer/satisficer decision-making style was significantly related to patient satisfaction scores in the year following surgery. This difference reached statistical significance at 6 months and remained a strong trend at 12 months. Patients who were less than extremely satisfied at both postoperative time points were more likely to portray the maximizer decision-making style. No other variables were associated with patient satisfaction at any time point. Maximizer/satisficer survey scores were not associated with self-reports of depression, anxiety, or illness anxiety. Mean scores on the maximizer/satisficer survey did not differ among the aesthetic, functional, and reconstructive groups. CONCLUSIONS: The maximizer/satisficer survey captures an aspect of patient care not traditionally measured by standard clinical psychometric screening tools to help predict satisfaction. A short questionnaire targeting consumer decision-making may be a helpful tool for preoperative counseling.

Evaluating the Association of Clinical Factors With Symptomatic Recurrence of Idiopathic Subglottic Stenosis.

Importance: Idiopathic subglottic stenosis (iSGS) is a progressive and potentially life-threatening condition with very few targeted treatment options. Objective: To characterize the clinical factors of patients with iSGS, including body mass index (BMI, calculated as weight in kilograms divided by height in meters squared), and evaluate their association with iSGS symptomatic recurrence. Design, Setting, and Participants: This retrospective medical record review included 186 adult patients with iSGS treated at a single tertiary referral center between January 1, 1989, and December 31, 2015. All data analysis took place from January 1, 2018 to June 30, 2018. Main Outcomes and Measures: The 3 BMI categories were examined for their association with iSGS recurrence. Outcome measurements included time to first symptomatic recurrence (TTFR) and recurrence-free survival (RFS). Comorbidities were recorded. Results: Of the 186 patients in the study, 182 (98%) were women; mean (interquartile range) patient age, 49 (41-60) years. At iSGS diagnosis, 65 (35%) patients were underweight or normal weight; 45 (24%) were overweight; and 76 (41%) were obese (class 1, 2, or 3). Median BMI was 27.4. Ninety-one patients experienced TTFR at a median of 14 months. Compared with underweight or normal-weight patients, the hazard ratios for the associations of overweight, obese class 1, and obese class 2/3 patients with recurrence were 1.14 (95% CI, 0.65-1.99), 1.74 (95% CI, 1.04-2.93), and 1.04 (95% CI, 0.54-1.99), respectively. No differences in concomitant medical treatment regimens were found. While several comorbidities (gastroesophageal reflux disease, hypertension, hyperlipidemia, and diabetes mellitus) were associated with increasing BMI, they were not associated with iSGS symptomatic recurrence on multivariable analysis. Conclusions and Relevance: Results of this retrospective review show that class 1 obesity was associated with an increased rate of iSGS symptomatic recurrence compared with underweight or normal-weight patients. This association was not seen in class 2 or class 3 obesity. Patients with class 1 obesity should be counseled about this risk to aid in the assessment and management of symptoms.

Primary vs Secondary Endosseous Implantation After Fibular Free Tissue Reconstruction of the Mandible for Osteoradionecrosis.

IMPORTANCE: The clinical and financial implications of the timing of dental rehabilitation after a fibula free tissue transfer (FFTT) for osteoradionecrosis (ORN) and osteonecrosis (ON) of the mandible have yet to be established. OBJECTIVE: To compare the outcomes of primary implantation vs secondary implantation after FFTT for ORN and ON of the mandible. DESIGN, SETTING, AND PARTICIPANTS: A retrospective review was conducted of 23 patients at a single tertiary academic referral center undergoing primary implantation or secondary implantation after FFTT for ORN and ON from January 1, 2006, to November 10, 2015. INTERVENTIONS: All patients underwent FFTT with primary implantation (n = 12) or secondary implantation (n = 11). MAIN OUTCOMES AND MEASURES: Outcomes of FFTT, dental implantation, implant use, diet, speech, and disease-free survival were reviewed. Fixed unit costs were estimated based on the mean cost analysis. RESULTS: Twenty-three patients (7 women and 16 men; mean [SD] age, 62.4 [8.2] years [range, 24-81 years]) met the inclusion criteria. Of these, 18 had ORN and 5 had ON. Dental implantation was performed at the time of FFTT for 12 patients and was performed secondarily for 11 patients. There were a mean of 5.2 implants per patient performed, for a total of 121 implants. There was 1 complete flap failure in the primary implantation group. Neither flap nor implant complications were affected by the timing of the implantation. Overall, the implant survival rate was 95% (55 of 58) in the primary implantation group and 98% (62 of 63) in the secondary implantation group. Time from FFTT to abutment placement (primary implantation, 19.6 weeks; secondary implantation, 61.0 weeks) was significantly shorter after primary implantation (P < .001). There was no clinical difference in postoperative complications and implant outcomes for ORN vs ON. Improvement in speech and oral competence in the primary implantation group vs the secondary implantation group was not statistically significant, given an experiment-adjusted P = .001 set as significant (normal speech, 9 vs 3; P = .02; and normal oral competence, 9 vs 3; P = .02). Disease-free survival was 91% (20 of 22 patients) overall. Fixed unit (U) costs were 1.0 U for primary implantation and 1.24 U for secondary implantation. CONCLUSIONS AND RELEVANCE: Patients undergoing primary implantation after FFTT for ORN and ON had a similar rate of complications compared with those undergoing secondary implantation. However, primary implantation allowed a faster return than secondary implantation to oral nutrition and prosthesis use. The fixed unit cost was reduced for those undergoing primary implantation. Although dental implantation was safe and effective in both groups, the decreased time to use and the decreased overall cost should prompt surgeons to consider primary implantation after FFTT for ORN and ON. LEVEL OF EVIDENCE: 3.

Methamphetamine Use With Subsequent Thyrotoxicosis/Thyroid Storm, Agranulocytosis, and Modified Total Thyroidectomy: A Case Report.

Thyroid storm is a rare, potentially lethal condition involving collapse of the hypothalamic-pituitary-thyroid feedback loop. Thyroid storm carries a significant mortality rate, thus requiring prompt identification and treatment. A 47-year-old woman presented to the emergency department complaining of palpitations, shortness of breath, and emesis for 24 hours after using methamphetamine. Past medical history was significant for untreated hyperthyroidism. Physical examination revealed a prominent, palpable thyroid. The Burch-Wartofsky-Score was 35. Management for thyroid storm included propylthiouracil (PTU), super saturated potassium iodide, intravenous hydrocortisone, and propranolol. However, a rare drug reaction to PTU on day 3 resulted in agranulocytosis. Propylthiouracil was withheld and a modified total thyroidectomy performed on day 8 without complications and the patient discharged on day 10 with levothyroxine. Undertreated hyperthyroidism may predispose patients to catecholamine-induced thyrotoxicosis due to catecholamine hypersensitivity. With known methamphetamine use, methamphetamine toxicity and a methamphetamine-exacerbated thyroid storm need to be included in the differential diagnosis in a patient presenting with signs of thyrotoxicosis. In addition, treating patients with agranulocytosis from PTU with a modified total thyroidectomy using ligation of the vascular supply as the initial surgical step limits release of thyroid hormone into the blood stream during thyroidectomy and decreases the possibility of intra operative thyroid storm.

Otorhinolaryngologic manifestations of Hartsfield syndrome: Case series and review of literature.

Diagnosis of Hartsfield syndrome includes recognition of three distinct clinical anomalies: holoprosencephaly, ectrodactyly, and bilateral cleft-lip and palate syndrome. A family including three male siblings all affected by Hartsfield syndrome presented to our institution for care. An autosomal dominant variant in Fibroblast Growth Factor Receptor 1 (FGFR1) was identified. This report focuses on otorhinolaryngologic manifestationsof Hartsfield syndrome, previously undescribed, including midline defects of holoprosencephaly, bilateral cleft-lip and palate, retrognathia, gastroesophageal reflux disease, external ear anomalies, eustachian tube dysfunction, and midface abnormalities, in addition to multidisciplinary, long-term management strategies. Multidisciplinary management is imperative in the care of these children with modification of approach based on their medical complexity.

Idiopathic Subglottic Stenosis: Long-Term Outcomes of Open Surgical Techniques.

Objectives Idiopathic subglottic stenosis (iSGS) is rare, and its cause remains elusive. Treatment options include empiric medical therapy and endoscopic or open surgery. We present our results for open surgical technique. Study Design Case series with chart review (1978-2015). Setting Tertiary academic center. Subjects/Methods Thirty-three patients (32 female; median age, 51 years) met inclusion criteria and underwent cricotracheal resection with thyrotracheal anastomosis, tracheal resection with primary anastomosis, or laryngotracheoplasty with rib grafting. Continuous variables were summarized using medians and ranges while categorical features are presented using frequency counts and percentages. Results Sixteen patients (48%) underwent a single-stage approach with immediate extubation or temporary intubation following surgery (median, 1 day; range, 1-3 days). Seventeen patients (52%) underwent a double-staged approach with a median time to decannulation of 35 days (range, 13-100 days). Twenty-four (73%) patients underwent a previous intervention. Median stay in the intensive care unit was 1 day (range, 0-3 days), with a median hospital stay of 4 days (range, 2-7 days). Recurrence requiring further surgical intervention was observed in 12 patients (36%). The median time to recurrence was 8 years over an average follow-up of 9.7 years. The most common complaint following surgery was change in voice quality (fair to poor; n = 10; 30%). Conclusions Open surgery should be reserved for refractory cases of iSGS; cricotracheal resection with thyrotracheal anastomosis is the preferred open technique. Recurrence may occur after open treatment, highlighting the importance of long-term follow-up. Patients should be counseled about the potential for worsening voice quality with the open approach.
