Objectives: Schwannoma arising from cervical sympathetic chain (CSC) is a rare clinical entity. CSC is hard to preserve in CSC schwannoma (CSCS) surgeries, resulting in Horner's syndrome (HS) and first bite syndrome (FBS). This article aims to explore our experience in successful preservation of CSC in CSCS surgeries. Methods: This is a retrospective review of CSCS cases treated at our tertiary medical institution between Apr 2018 and March 2022. Only cases with successful intraoperative preservation of CSC were included. Results: In total, 3 cases were included. There were 2 male patients and 1 female patient. Their age was between 38 years old and 66 years old (average and median age was 52 and 51 years old, respectively). Presenting symptom was neck mass for all them, 2 of which were on the left side, while 1 was on the right. Intracapsular enucleation of the CSCS was attempted and achieved in all 3 cases. Hemorrhage from the inner surface of capsules was diffuse and heavy. Constant saline irrigation, suction, and bipolar coagulation were needed to achieve hemostasis. Postoperative HS presented between 4 hours and 14 hours after surgery for all 3 patients, which took 1 month to 3 months to recover, whereas FBS did not occur in any patient. Median duration of follow-up was 6 months. No recurrence was observed. Conclusions: Intracapsular enucleation should be attempted in CSCS surgeries, although hemorrhage might be diffuse and hard to control. When intracapsular enucleation was achieved, postoperative FBS can be avoided, while postoperative HS could occur, but its recovery was satisfactory. [ABSTRACT FROM AUTHOR]

Objectives: Pharyngocutaneous fistula (PCF) formation following open surgical treatment of hypopharyngeal cancer (HPC) is a common and troublesome complication. To date, the postoperative protocol of restarting oral intake is not clear, and vast discrepancies exist in the literature and among institutions. This study aimed to explore the impact of a postoperative protocol of restarting oral intake on PCF formation after open surgical treatment of primary HPC, and its impact on overall survival (OS) and swallowing function based on the functional outcome swallowing scale (FOSS). Materials and Methods: This was a prospective observational study of 42 patients who received open surgical treatment for primary HPC at Beijing Friendship Hospital between April 2019 and August 2021. This cohort included two groups: patients who restarted oral intake on the 10th postoperative day (Group 1), and those who started on the 20th (Group 2). The Chi-square test and Fisher's exact chi-squared test were used for comparing qualitative data among the groups. Results: Group 1 (n = 27) and Group 2 (n = 15) were comparable in clinical characteristics. PCF occurred in 7 (25.9%) patients in Group 1, while none occurred in Group 2 (P = 0.038). The 2-year OS of all 42 patients was 75.6%; 65.8% and 93.3% for Groups 1 and 2, respectively (P = 0.07). The swallowing function was satisfactory (FOSS Grades 0–III) for 19 (70.4%) patients in Group 1 and 15 (100%) patients in Group 2 (P = 0.035). Laryngeal preservation was achieved in 25 (59.5%) patients, while decannulation was successful in 22 (88.0%) patients. Conclusions: Delayed oral feeding significantly reduces PCF after open surgical treatment of primary HPC, and improves the swallowing function outcome without jeopardizing the OS.
