Objectives: . Empty nose syndrome (ENS) is a rare postoperative complication that can develop following turbinate surgery. Here, we present our clinical experience and a comprehensive analysis of the inferior meatus augmentation procedure with autologous costal cartilage (IMAP-ACC) as a treatment for ENS. Methods: . We retrospectively reviewed the medical records of patients diagnosed with ENS who underwent IMAP-ACC at a tertiary referral center between November 2015 and November 2023. Symptom improvement was evaluated using the Empty Nose Syndrome 6-Item Questionnaire (ENS6Q) score before and after the procedure. In addition, perioperative complications and instances of revision surgery were systematically examined. Results: . Of the 32 patients who underwent IMAP-ACC, clinical analysis included 20 patients (16 men, 4 women) with a mean age of 39.1±11.5 years and a mean follow-up duration of 61.2±28.8 months. The mean ENS6Q score significantly improved from 17.5±5.3 preoperatively to 9.1±6.0 at the final follow-up (P<0.001). In a subgroup analysis of 16 patients with available early follow-up data, significant reductions in ENS6Q scores were observed both at early follow-up (7.8±5.7) and long-term follow-up (8.6±6.5), compared to the preoperative value (18.2±5.6). Across all 32 patients, nasal obstruction was the most common perioperative complication (34.4%), necessitating reoperation in four patients (12.5%). The majority of complications were effectively managed with a conservative approach. Conclusion . IMAP-ACC has proven to be a valuable and durable treatment option for patients with ENS, demonstrating sustained symptom improvement over extended follow-up periods.

Solitary fibrous tumors (SFTs) are spindle-cell tumors that rarely arise within extrathoracic area. Massive SFTs involving the pterygopalatine fossa are extremely rare and surgical excision represents a multidisciplinary surgical challenge. We present a case of 64-year-old female with a huge mass originating from the pterygopalatine fossa invading the skull base. Distinct microscopic findings and a positive nuclear staining of signal transducer and activator of transcription 6 (STAT-6) pathologically confirmed SFT. The right internal maxillary artery branch was embolized preoperatively and a surgical excision was performed through a combined technique of transpalatal, mid-facial degloving and endoscopic approach. Postoperative radiotherapy successfully removed the remnant tumor adjacent to the carvenous sinus. Follow- up MR images showed no evidence of recurrence for two years. To our knowledge, there has been no previous report of the successful treatment of this vast extent of SFT in the pterygopalatine region via endoscopic-external-combined approach and radiotherapy.

Primary hyperparathyroidism (PHPT) is a common endocrine disorder characterized by elevated parathyroid hormone levels. In most cases, the disease involves a single parathyroid adenoma, followed by parathyroid hyperplasia, but the incidence of ectopic parathyroid adenoma is rare. However, in cases where the parathyroid hormone level remains high even after parathyroid surgery, an ectopic parathyroid gland should be considered. Here in a case of a 60-year-old female who presented PHPT is reported. She had undergone a surgical removal of the parathyroid gland of suspected hyperplasia, but still represented persistent PHPT, postoperatively. Ectopic mediastinal parathyroid adenoma was identified by 99mTc-sestamibi parathyroid scan and surgical excision via a median sternotomy approach was performed. Thirty-eight months postoperatively, there was no evidence of recurrence. Preoperative localization assessment is critical for minimizing surgical failure in cases of PHPT.

BACKGROUND: Hepatitis B virus (HBV) infection leads to hepatic and extrahepatic manifestations including chronic kidney disease (CKD). However, the association between HBV and CKD is not clear. This study investigated the association between chronic HBV infection and CKD in a nationwide multicenter study. METHODS: A total of 265,086 subjects who underwent health-check examinations in 33 hospitals from January 2015 to December 2015 were enrolled. HBV surface antigen (HBsAg) positive cases (n = 10,048), and age- and gender-matched HBsAg negative controls (n = 40,192) were identified. CKD was defined as a glomerular filtration rate (GFR) < 60 mL/min/1.73 m² or proteinuria as at least grade 2+ of urine protein. RESULTS: HBsAg positive cases showed a significantly higher prevalence of GFR < 60 mL/min/1.73 m² (3.3%), and proteinuria (18.9%) than that of the controls (2.6%, P < 0.001, and 14.1%, P < 0.001, respectively). In the multivariate analysis, HBsAg positivity was an independent factor associated with GFR < 60 mL/min/1.73 m² along with age, blood levels of albumin, bilirubin, anemia, and hemoglobin A1c (HbA1c). Likewise, HBsAg positivity was an independent factor for proteinuria along with age, male, blood levels of bilirubin, protein, albumin, and HbA1c. A subgroup analysis showed that HBsAg positive men but not women had a significantly increased risk for GFR < 60 mL/min/1.73 m². CONCLUSION: Chronic HBV infection was significantly associated with a GFR < 60 mL/min/1.73 m² and proteinuria (≥ 2+). Therefore, clinical concern about CKD in chronic HBV infected patients, especially in male, is warranted.
