Four-dimensional computed tomography and ultrasonography for prediction of pathological parathyroid location: a retrospective review of a single surgeon's patients at a single institution.

Background: Pre-operative imaging is a well-established practice for managing hyperparathyroidism with the plan for excision; however, there is a paucity of information regarding the success rate of concordant imaging studies. Our goal was to compare the accuracy (sensitivity) of four-dimensional computed tomography (4DCT) and ultrasound (US) when predicting the side and quadrant of parathyroid lesions, confirmed with surgical location (from a single surgeon). Methods: A retrospective review of 437 patients from a single surgeon undergoing parathyroidectomy from December 2013 to January 2020 at an academic medical center was performed. Masses >5 mm in dimension in eutopic parathyroid locations were identified as possible parathyroid lesions on 4DCT. A unique codified system was utilized to accurately record imaging results for each modality and compared to surgical findings. Results: Four hundred and thirty-seven patients underwent parathyroid surgery, of those 431 underwent 4DCT, 413 underwent US, and 408 underwent both. 4DCT accurately lateralized lesions in 319 (74.0%; N=431). US lateralized lesions in 265 (64.2%; N=413). The sensitivity for lateralization was 81.2% and 69.9% for 4DCT and US, respectively. Conclusions: 4DCT and US identify the majority of parathyroid lesions. 4DCT outperformed US in lateralization yet both modalities remain useful and are complimentary in planning for successful parathyroidectomy. Newer imaging approaches such as 18F-choline positron emission tomography/computed tomography (PET/CT) and artificial intelligence as an augmentation to imaging review may play in role to identify parathyroid adenomas/hyperplasia, but their roles have yet to be clearly defined.

Extralaryngeal Spread in Total Laryngectomy: Comparing the Need for Thyroidectomy.

Objective: At our institution, thyroid preservation during total laryngectomy (TL) varies by surgeon, offering a distinctive dataset to compare disease outcomes in TL patients with or without thyroidectomy. Methods: This retrospective chart review study, conducted at a tertiary referral medical center, comprises patients who underwent TL for laryngeal or hypopharyngeal squamous cell carcinoma from 2014 to 2022. The study includes data on patient demographics, surgeries, pathological staging, tumor subsites, thyroid involvement, and adjuvant therapy. Results: In this study, 147 patients, mostly male (83%) and white (82%), were included. Surgeries comprised 60 hemi thyroidectomies, 35 total or completion thyroidectomies, 48 without thyroid removal, and 4 isthmusectomies. Data analysis compared these 4 groups and the cohort of no thyroid removal (NT) versus any thyroidectomy (T = 99). Among the 99 patients, 27 showed positive gland involvement, primarily due to direct disease extension (26 cases). No significant difference was found in recurrence rates or recurrence-related mortality among the 4 groups or between NT and T (P = .156). However, there was a significant difference in T staging and prognostic staging among the groups and between NT versus T (P = .043). The NT cohort showed a higher likelihood of being T3, while T was more likely to be T4. Conclusion: We found no significant difference in recurrence rates or mortality between TL patients with or without thyroid removal. However, those without thyroid removal often had lower T stages. Notably, 27% of thyroidectomy patients had gland invasion, highlighting the importance of thyroid removal in TL.

Diagnosis and management of facial nerve palsy secondary to granulomatosis with polyangiitis - A systematic review.

OBJECTIVE: Granulomatosis with polyangiitis is associated with otolaryngologic complaints in 70-95 % of cases, with the most common being serous otitis media. In rare cases, patients may experience facial nerve palsy in conjunction with otologic or nasal symptoms; and, often, initially present to an otolaryngologist. It is important for healthcare professionals to be able to recognize the nuisances of facial nerve palsy as a potential presentation of granulomatosis with polyangiitis. STUDY DESIGN: Systematic review. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Protocol, PubMed and MED-LINE Databases were queried for articles published from January 2007 to December 2022 describing facial nerve palsy in the context of Granulomatosis with polyangiitis, formerly known as Wegener's Granulomatosis. The keywords included "facial nerve palsy", "facial palsy", "granulomatosis with polyangiitis", "Wegener's granulomatosis", "ANCA positive" in the title/abstract. All full-text articles available in English were screened, including single case presentations. Abstracts, commentaries, and publications deemed outside the scope of our study aims were excluded from review. After removal of duplicate articles, a total of 85 articles were screened. After applying inclusion and exclusion criteria, 14 articles were included in the review. RESULTS: There were a total of 28 reports of facial nerve palsy in the literature in patients who were eventually diagnosed with granulomatosis with polyangiitis. The patients' ages ranged from 14 to 68 years old. None of the patients had been previously diagnosed with GPA, and a majority of them presented initially with other otologic symptoms. Hearing loss was reported in 24 patients (86 %), otalgia was present in 11 patients (39 %), and otorrhea was present in 6 patients (21 %). Bilateral facial paralysis was reported in 10 patients in the literature (36 %). In total, 16 patients underwent surgery for facial paralysis: 6 tympanomastoidectomies, 4 mastoidectomies, 2 explorative tympanotomies. Surgery was generally considered ineffective in resolving facial weakness. All patients ended up receiving some combination of steroids and immunosuppressant, most commonly prednisolone and cyclophosphamide or rituximab, which was eventually transitioned to azathioprine for maintenance. Unlike auditory thresholds, which remained decreased in two patients, all patients recovered facial function following appropriate medical treatment of their vasculitis. CONCLUSIONS: Facial nerve paralysis in patients with granulomatosis with polyangiitis is a rare but treatable phenomenon. In patients with intractable otitis media, unresolving facial palsy, or a combination of otologic issues, it is important to consider GPA as a possible source. The prognosis for facial function appears to be excellent in patients who undergo appropriate treatment for vasculitis, but further studies are needed for confirmation.

Complications of Mandibular Fracture Repair.

Mandible fracture management has evolved dramatically. Therefore, the variety of surgical complications associated with mandibular fractures, and their incidences, have continued to change as well. This article aims to assess the most common and most concerning complications that can occur secondary to management of mandibular fractures by examining categories of complication types. This article also explores factors and techniques associated with reduced rates of complications as well as the management of complications.

T-tubes Through Cartilage Tympanoplasty: Is It Worth the Perforation Risk?

OBJECTIVE: To review a single surgeon's experience with T-tube placement through cartilage tympanoplasty versus native tympanic membrane for long-term ventilation of the chronic ear and residual perforation rates following tube removal. STUDY DESIGN: Retrospective chart review. SETTING: Two tertiary referral centers. PATIENTS: One hundred sixteen patients (4-71 yr of age) who underwent either total island cartilage tympanoplasty or posterior palisade cartilage tympanoplasty with T-tube placement primarily or secondarily from 1998 to 2016. MAIN OUTCOME MEASURES: Long-term outcome of each T-tube was recorded with respect to retention and patency, and tympanic membrane status following either tube removal or extrusion. Audiometric data, age, sex, diagnosis, and procedure(s) performed were considered. RESULTS: There were 116 patients (122 total ears and 139 total T-tubes) included: 57 ears underwent total island cartilage tympanoplasty with tube placed through cartilage and 65 ears underwent posterior island graft with tube placed through native tympanic membrane. Sixty-eight T-tubes were placed in the total island cartilage group with three (4.4%) residual perforations following removal. Seventy-one T-tubes were placed in the posterior palisade graft group with six residual perforations (8.5%) following removal or extrusion. The mean retention rate for the T-tubes was 3.93 years for the total island tympanoplasty group and 3.58 years for the posterior palisade tympanoplasty group. The mean follow-up for total island tympanoplasty and posterior palisade tympanoplasty was 5.36 and 5.66 years, respectively. CONCLUSION: Our data suggest that T-tube placement through cartilage tympanoplasty is worthwhile providing long-term ventilation to the middle ear and portends no higher risk for residual perforation than T-tube placement through native tympanic membrane.
