Leprosy as a cause of nasolacrimal duct obstruction.

Leprosy, also known as Hansen disease, is an airborne spread disease caused by Mycobacterium leprae (M. leprae) which commonly presents with skin lesions, peripheral neuropathy, and ocular involvement. This report describes a patient who presented with epiphora secondary to chronic nasolacrimal duct obstruction four years after completing antimicrobial treatment for tuberculoid leprosy. At the time of endoscopic dacryocystorhinostomy (DCR), the lacrimal sac demonstrated chronic dacryocystitis with granulomatous inflammation and a Fite positive staining bacterial rod-like structure. Pathological examination of the surgical specimen demonstrated numerous non-necrotizing granulomas in a perivascular and neural distribution, compatible with sequelae of previously treated M. leprae infection. The patient has remained symptom free six months after surgery.

Orbital decompression surgery among Medicare beneficiaries in the post-teprotumumab era.

KEY POINTS: Utilization of orbital decompressions (ODS) increased (CAGR: +3.2%) from 2000 to 2019. FDA approved teprotumumab in January 2020; ODS utilization decreased (CAGR: -14.9%) from 2019 to 2022. In 2022, total spending was substantially higher for teprotumumab ($325 million) than surgery ($580,000).

Defining the Health Utility Value of Medical Management of Chronic Rhinosinusitis: A Prospective Pilot Study.

The extent to which medical management of chronic rhinosinusitis (CRS) may improve health utility value (HUV) remains unknown. We conducted a prospective pilot study to longitudinally assess HUV via the EQ-5D-5L questionnaire in patients with CRS who were receiving medical therapy but did not undergo sinus surgery. The primary study outcome was HUV at 12-month follow-up; secondary end points included HUV at baseline and 3- and 24-month follow-up. Our study enrolled 115 patients who received the following medical treatments: saline irrigations (n = 83, 72.2%), steroid sprays (n = 93, 80.9%), antihistamines (n = 64, 55.7%), steroid irrigations (n = 29, 25.2%), and oral antibiotics (n = 58, 50.4%). There was a statistically significant improvement (mean, +0.073; P = .003) in HUV at 12 months (minimum clinically important difference, 0.055) as compared with baseline. However, there was no statistically significant trend in HUV over time between baseline and 24-month follow-up (P = .3033). These findings can inform cost-effectiveness research as new medical therapies for CRS emerge.

Endoscopic management of lateral sphenoid cerebrospinal fluid leaks: Identifying a radiographic parameter for surgical planning.

OBJECTIVE: Repair of cerebrospinal fluid (CSF) leaks of the lateral recess of the sphenoid (LRS) sinus can be challenging to accomplish via an endoscopic transphenoidal approach. The endoscopic transpterygoid approach can improve surgical access to the lateral recess but requires more extensive surgical dissection. We review our experience with LRS CSF leak repair via both techniques to determine whether preoperative radiologic data can help predict the most appropriate surgical approach. METHODS: Electronic medical records of patients with LRS CSF leaks were retrospectively reviewed at a single tertiary referral center. Radiographic measurements from preoperative computed tomography images were reviewed. RESULTS: Twenty-two LRS CSF leaks were identified. The transphenoidal and transpterygoid approach were used in 6 (27.3%) and 16 (72.7%) cases, respectively.The mean vidian canal to foramen rotundum angle of the repairs accessed transphenoidally as compared to the transptyergoid approach were not significantly different (41.93° ±10.91, 40.72° ±19.49, respectively; P = .63). However, the mean volume of the LRS accessed by the transpterygoid approach was significantly greater compared to those accessed through the transphenoidal approach (0.97 cm3 ± 0.48, 0.39 cm3 ± 0.40, respectively; P = .04). A LRS volume of 0.400 cm3 or greater predicted the use of the transpterygoid approach with 93.3% sensitivity and 60.0% specificity. CONCLUSION: This study demonstrated that LRS CSF leaks that necessitated repair by the transpterygoid approach, rather than transphenoidal approach, were in the context of significantly larger lateral recess. Assessment of the LRS volume is a quantifiable parameter to aid in preoperative surgical planning. LEVEL OF EVIDENCE: Level 4.

Does the Timing of Middle Turbinate Resection Influence Quality-of-Life Outcomes for Patients with Chronic Rhinosinusitis?

Objective To evaluate the impact of bilateral middle turbinate resection (BMTR) on patient-reported quality of life following primary and revision endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS). Study Design Prospective cohort study. Setting Tertiary care center. Subjects and Methods Patients with CRS who were recruited from 11 otolaryngologic practices completed the Sino-Nasal Outcome Test-22, Chronic Sinusitis Survey, and EuroQol 5-Dimension questionnaires at baseline, as well as 3 and 12 months after ESS. In the primary ESS cohort (n = 406), patients who underwent BMTR (n = 78) at the time of surgery were compared with patients (n = 328) whose middle turbinates were preserved. In the revision ESS cohort (n = 363), a similar comparison was made between patients who did (n = 64) and did not (n = 299) undergo BMTR. Results Sino-Nasal Outcome Test-22, Chronic Sinusitis Survey, and EuroQol 5-Dimension scores showed similar improvements for both the turbinate resection and preservation cohorts at 3 months ( P < .001) and 12 months ( P < .001) after surgery. For patients who underwent revision surgery, the performance of BMTR resulted in greater improvement in Chronic Sinusitis Survey scores at 1 year as compared with the turbinate preservation group (change from baseline: 28.1 vs 20.7, respectively; P = .026). History of tobacco use and the presence of nasal polyps did not affect clinical outcomes at any time point. Conclusion Patients who underwent BMTR during primary and revision sinus surgery reported similar benefits in quality-of-life outcomes 1 year after surgery. In select patients undergoing revision sinus surgery, the performance of BMTR results in improved disease-specific quality of life.

The Impact of Angiotensin-Modulating Antihypertensives on Time Interval to Revision Surgery for Nasal Polyps.

OBJECTIVE/HYPOTHESIS: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) have been shown to suppress expression of periostin, a matricellular protein that is markedly elevated in nasal polyp tissue. The purpose of this study was to determine whether use of these antihypertensive agents affects the time to revision sinus surgery in patients with polyp regrowth. STUDY DESIGN: Case series with chart review. SETTING: Academic medical center. SUBJECTS AND METHODS: Records were reviewed for 330 patients who underwent ≥2 operations for chronic sinusitis with nasal polyps from April 1987 through August 2015. The time between surgical interventions was compared with patient demographics and clinical characteristics, including use of ACEIs and ARBs. RESULTS: Sixty patients were taking ACEIs or ARBs during the study period, of which 32 had concurrent asthma. The mean interval between polyp operations was 61.0 ± 45.2 months (range, 2-228.6 months). Among patients with asthma (n = 197), the mean time to revision surgery was prolonged by >2 years for those taking ACEIs or ARBs (81.0 vs 54.5 months, P = .006). A similar impact on time to revision surgery was not observed for nonasthmatics taking these medications (61.0 vs 65.2 months, P = .655). CONCLUSION: Use of ACEIs and ARBs is associated with an increased time to revision sinus surgery among patients with concurrent nasal polyps and asthma. A possible mechanism of this observed effect is suppression of periostin expression through inhibition of the angiotensin pathway.

Development and validation of a new health-related quality of life instrument for patients with sinusitis.

BACKGROUND AND OBJECTIVE: There are few validated measures of sinusitis-specific health-related quality of life (HRQL). This study used patient focus and pretesting groups followed by a prospective cohort study to develop and validate a HRQL instrument for patients with sinusitis. METHODS: Instrument development involved a systematic literature review, use of expert input, and patient focus and pretesting groups. Patients were recruited from the practices of primary care providers and otolaryngologists. The derived survey instrument then underwent prospective testing in patients with acute sinusitis, chronic sinusitis, allergic rhinitis, and asymptomatic controls. Reduced item scales of the original instrument were developed for symptom frequency and bothersomeness. The psychometric properties of the survey instrument were evaluated for reliability, construct validity, responsiveness, and interpretability. RESULTS: In the prospective study, 47 patients with acute sinusitis and 50 patients with chronic sinusitis were compared to 18 patients with allergic rhinitis and 60 patients without nasal symptoms. Forty-three (91.5%) patients with acute sinusitis completed the questionnaire at baseline and at 1-month follow-up. Internal consistency was high for the symptom impact scale for acute and chronic sinusitis patients. The symptom frequency and especially bothersomeness scales had lower internal consistency particularly for acute sinusitis patients. Reproducibility among surgical patients retested prior to their procedure was good for each scale. A high degree of disciminant validity was demonstrated when comparing sinusitis patients to other groups, and a high degree of convergent validity was seen when the new measures were compared to other HRQL measures at baseline. Among patients with acute sinusitis, the responsiveness and interpretability of the symptom frequency, bothersomeness and impact scales were excellent. CONCLUSIONS: This study developed and validated a new sinusitis-specific HRQL instrument. The instrument included symptom frequency, bothersomeness and impact scales. It was shown to be valid in patients with acute and chronic sinusitis, and highly responsive and interpretable in acute sinusitis patients managed in the primary care setting.

Validity of a new health-related quality of life instrument for patients with chronic sinusitis.

OBJECTIVE/HYPOTHESIS: To assess the validity and responsiveness of a new health-related quality of life (HRQL) instrument for patients with chronic sinusitis. STUDY DESIGN: Prospective case series. METHODS: Patients with chronic sinusitis undergoing endoscopic sinus surgery were assessed in two otolaryngology practices affiliated with an academic hospital. Patient-reported HRQL was assessed using a new instrument (includes symptom frequency, bothersomeness, and impact scales), the Chronic Sinusitis Survey (CSS), and the generic SF-12 at baseline and 3 months postsurgery. The psychometric properties of the new instrument were assessed including reliability, validity, responsiveness, and interpretability. RESULTS: Among 50 enrolled patients, 49 underwent surgery and 39 (80%) completed 3-month follow-up. Internal consistency was high for the symptom impact scale. The symptom frequency and, especially, bothersomeness scales had lower internal consistency and were comparable with the CSS. Correlation analyses support the construct validity of the new measure compared with the CSS and SF-12. The responsiveness of the new instrument was excellent and similar to or better than the CSS. The mean score change was linearly related to the patient's global self-assessment, although the CSS symptom and total score better discriminated patients with major or moderate degrees of improvement. CONCLUSIONS: This study demonstrates the validity and responsiveness of a new rhinosinusitis-specific HRQL instrument, the Rhinosinusitis Quality of Life survey, in patients with chronic sinusitis. The instrument's symptom frequency, bothersomeness, and impact scales compare favorably with a previously validated disease-specific and a generic HRQL measure. If validated in other patient populations, this disease-specific instrument may be useful in assessing severity and outcomes of treatment for sinusitis.

Myospherulosis following sinus surgery: pathological curiosity or important clinical entity?

OBJECTIVES/HYPOTHESIS: Myospherulosis is a foreign body reaction to lipid material used on nasal packing at the conclusion of sinus surgery. This reaction has been associated with postoperative adhesion formation. The purpose of the study was to determine whether the occurrence of myospherulosis has an adverse effect on clinical outcome following sinus surgery. STUDY DESIGN: Case-control study at an academic medical center. METHODS: Thirty-two cases of myospherulosis were identified in 28 patients (4 with bilateral disease) who underwent sinus surgery between 1989 and 1999. Cases were staged according to histological and radiological grading systems. Clinical outcome was compared with a control group of 28 patients who had similar surgery during the same time period. RESULTS: Patients with myospherulosis were found to have a significantly higher likelihood of developing postoperative adhesions compared with control subjects (50% vs. 18%, respectively [P =.023]). Histological stage, based on the extent of lipid vacuoles and spherules (erythrocyte remnants) present in the surgical specimen, was found to correlate with disease severity based on preoperative sinus computed tomography staging (P =.009). Patients with myospherulosis tended to have a shorter interval between their last two surgeries than did control subjects (2.2 +/- 2.1 vs. 4.5 +/- 7.1 y, respectively [P =.086]). Patient age, sex, comorbid conditions, CT stage, and number of previous operations were not predictive for the occurrence of myospherulosis. CONCLUSIONS: Patients who develop myospherulosis from lipid-based packing material used during sinus surgery are more likely to form postoperative adhesions. These adhesions appear to be clinically relevant and may hasten the need for revision surgery.

Laser eustachian tuboplasty: a preliminary report.

OBJECTIVES/HYPOTHESIS: Surgical correction of eustachian tube dysfunction remains an elusive challenge. Repeat ventilation tube placement is often inadequate to prevent tympanic membrane and middle ear complications. Endoscopic analyses of eustachian tube dynamics have localized the site of primary pathophysiology to within the cartilaginous tube. The study investigated the feasibility, safety, and efficacy of a new endoluminal eustachian tube operation for the treatment of eustachian tube dysfunction. STUDY DESIGN: Prospective, institutional review board-approved surgical trial in a tertiary-care medical center. METHODS: Ten patients with more than 5 consecutive years of intractable otitis media with effusion recurring after two or more tympanostomy tube placements were treated with unilateral laser eustachian tuboplasty. Surgery was performed on an outpatient basis with the use of general anesthesia and combined both transnasal and transoral approaches. A 980-nm diode or argon laser was used to vaporize an appropriate amount of mucosa and cartilage on the posterior wall of the tubal lumen. Preoperative and postoperative dynamic video eustachian tube function analyses were compared. Outcome measures were presence or absence of middle ear effusion and impedance tympanograms. RESULTS: Five patients had at least 12 months of follow-up, and three of them had absence of any effusion (60%). Two patients had recurrence of their otitis media with effusion and required tympanostomy tubes again. Five patients had at least 6 months of follow-up, and four of them had absence of any effusion. The remaining patient had recurrence of otitis media with effusion and received a tympanostomy tube again. Overall results for all 10 patients after 6 months were 7 free of effusion (70%). There were no intraoperative complications. Postoperative complications were limited to minimal peritubal adhesions and one intranasal synechia. CONCLUSIONS: Preliminary results suggest that laser eustachian tuboplasty is safe and efficacious in the treatment of intractable eustachian tube dysfunction. Further study will be necessary to determine whether laser eustachian tuboplasty is a suitable alternative to repeated tympanostomy tube placement in selected patients.

Mitomycin C for the prevention of adhesion formation after endoscopic sinus surgery: a randomized, controlled study.

OBJECTIVE: Mitomycin C (MMC) is an antineoplastic agent that has been shown to decrease scar tissue after ophthalmologic surgery. Our goal was to determine whether the application of MMC at the conclusion of sinus surgery decreases the incidence of postoperative adhesion formation. METHODS: At the completion of endoscopic sinus surgery in 55 patients, a cotton pledget saturated with 1 mL of 0.4 mg/mL MMC was placed for 4 minutes in the right or left middle meatus and a similar saline-soaked pledget was placed on the opposite side. Patients were examined postoperatively by a masked observer for the presence of synechiae and mucosal changes. RESULTS: Postoperative adhesions were observed in 16 patients (29%) with a mean follow-up of 4.1 months. These adhesions were bilateral in 6 patients (10.9%) and unilateral in 10 patients (18%). Unilateral adhesions were observed on only 2 sides (3.6%) treated with MMC and 8 controls (14.5%) (P = 0.058). No adverse effects were observed. CONCLUSIONS: MMC was found to be safe to use during sinus surgery, and it may reduce the incidence of postoperative adhesions at the dosage used in this study. SIGNIFICANCE: Because of the observed trend toward decreased synechiae formation with MMC application, further trials using higher concentrations and application times are warranted.
