Head and Neck Dystonia Following Chimeric-Antigen Receptor T-Cell Immunotherapy: A Case Report.

Chimeric antigen receptor T-cell therapy (CAR-T) is a novel immunotherapy used for the treatment of refractory B-cell leukemias and lymphoma. As clinical trials continue to expand, multiple treatment toxicities have been documented. Treatment-associated toxicities are typically systemic, however, focal manifestations have been described. We present a unique case of a 55-year-old female who developed oropharyngeal and laryngeal dystonia following CAR-T therapy. This case points to a possible association between CAR-T therapy and focal head and neck dystonia. Laryngoscope, 2020.

Nasoseptal flap for reconstruction after robotic radical tonsillectomy.

BACKGROUND: The nasoseptal flap has revolutionized reconstruction of ventral skull base defects. The past decade is also noticeable by the evolution of transoral robotic surgery (TORS). Reconstruction of the oropharyngeal defect is challenging. Good reconstructive options with less cicatricial retraction are desirable and still lacking in the literature. METHODS: Cadaver dissection and illustrative case are used to show the feasibility of harvesting a nasoseptal flap to reconstruct oropharyngeal defect after radical tonsillectomy. Surgical resection included part of the soft palate and tongue base. RESULTS: The flap was sufficient to cover two-thirds of the tonsillar defect during the cadaver dissection. In our illustrative case, the flap filled the palatal defect and also was sufficient to cover the superior half of the tonsillar defect. CONCLUSION: The nasoseptal flap has shown to be feasible and reliable for reconstruction of the oropharyngeal defect after TORS. When soft palate resection is warranted, this flap provides excellent coverage. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2495-E2498, 2016.

The Efficacy of Mitomycin C in the Treatment of Laryngotracheal Stenosis: Results and Experiences with a Difficult Disease Entity.

BACKGROUND/AIMS: Laryngotracheal stenosis (LTS) is a difficult entity to treat, with many patients requiring multiple procedures. Our study assessed the efficacy of mitomycin C (MMC) application as complimentary treatment of LTS. METHODS: We reviewed clinical charts of patients with operative procedures for LTS between January 2005 and May 2013. Patients were grouped according to mitomycin use. Several outcome measures were assessed, including the number of procedures and time between procedures. RESULTS: Seventy-one patients were included in the study (30 MMC, 41 non-MMC). They underwent similar numbers of procedures (2.3 MMC, 2.0 non-MMC, p > 0.05). The average time between procedures was 360 (MMC) and 178 (non-MMC) days (p = 0.015). Multiple treatments with mitomycin increased the duration between procedures (366 vs. 340 days, multiple vs. single application, p > 0.05). Fewer mitomycin patients underwent procedures for respiratory distress than non-MMC patients (6.6 vs. 19.5%, p > 0.05). Mitomycin use increased the duration between procedures in patients treated specifically for subglottic stenosis (375 vs. 186 days, p > 0.05). CONCLUSION: Our results and experiences with mitomycin demonstrate it is an effective agent for adjuvant treatment of LTS. Its use lengthens the symptom-free period, with further improvement demonstrated when patients expected to undergo multiple surgeries receive multiple mitomycin treatments.

Radiotherapy-associated euthyroid Graves ophthalmopathy following floor-of-mouth surgery: a case report.

The thyroid gland is commonly included in the radiation field during treatment of nonthyroidal neoplastic disease of the head and neck. As a result, thyroid abnormalities sometimes occur following external irradiation. We report an unusual case of radiotherapy-associated Graves ophthalmopathy 5 months after adjuvant external irradiation of the head and neck in a euthyroid patient who had undergone wide local excision of squamous cell carcinoma from the floor of the mouth.
