Diagnostic Challenges in Chondroblastic Maxillary Osteosarcoma: A Case Report.

The diagnosis of craniofacial osteosarcoma can be quite challenging, and the condition often goes unrecognized for a considerable period of time. In this report, we discuss the case of a 21-year old woman who presented with a one-year history of a small swelling over the left maxillary alveolar ridge. Upon further investigation, the histopathological examination showed high-grade chondroblastic osteosarcoma. The option of four cycles of neoadjuvant chemotherapy regimen preoperatively was chosen, and left inferior maxillectomy was performed along with reconstruction with obturator prosthesis. This case highlights the difficulties encountered in such rare cases of craniofacial osteosarcomas both in terms of the delay in the establishment of the diagnosis as well as management protocol. A high index of suspicion is required in cases of craniofacial osteosarcoma and early surgical resection with adequate safety margins is warranted.

Thyroglossal duct surgery. What is the acceptable recurrence rate?

OBJECTIVES: To present experiences of different specialties in the treatment of thyroglossal duct cysts (TGDCs) and subsequent complications in multiple centers.  Methods: A retrospective cross-sectional study of all cases of TGDC for a period of 11 years from 2008-2019 by different departments from 3 different centers in Jeddah, Kingdom of Saudi Arabia (King Faisal Specialist Hospital and Research Centre, Bakhsh Hospital and International Medical Center). Results: Forty-nine patients were included. The type of surgery performed plays a significant role in recurrence (p less than 0.001). The Sistrunk procedure had a lower recurrence rate (0%) than simple excision (70%) and has showed a significantly long recurrence-free interval (p less than 0.001). Higher recurrence rates are associated with higher postoperative complications (p=0.002). Patients who underwent pre-operative fine needle aspiration did not have any recurrence during the follow-up period. Conclusion: The Sistrunk procedure is the gold standard technique with the highest recurrence-free interval rate. Fine needle aspiration could be recommended as a less invasive procedure to exclude malignancy.

Nerve Block for Septorhinoplasty: A Retrospective Observational Study of Postoperative Complications in 24 Hours.

Septorhinoplasty is a surgical procedure that provides functional improvements and esthetic adjustments to the appearance of the nose. Pain is a common postoperative complication, and pain management is known to decrease postoperative complications and total cost. Local anesthetics can cost-effectively decrease postoperative pain scores and reduce analgesic requirements. The primary objective of this study was to assess the effect of bilateral facial nerve blocks given with general anesthesia on pain scores and the use of postoperative analgesia. The secondary objective was to compare the vital signs stability between a group given bilateral facial nerve blocks with general anesthesia and a group given general anesthesia only. We conducted a retrospective observational study among 40 patients who were divided into two groups, each containing 20 patients. The patients in the nerve block (NB) group received general anesthesia and bilateral facial blocks of the infraorbital and infratrochlear nerves via 5 ml of 0.25% levobupivacaine with 5 ml of diluted adrenaline 1:100,000. Patients in the Control group received general anesthesia only. Both groups received the same local injection of a mixture of 5 ml of 1% lidocaine and 5 ml of 1:100,000 epinephrine at the surgical site, along with the standard general anesthesia. A numerical rating scale, the visual analog scale (VAS), was used to evaluate postoperative pain at 15, 30, and 45 minutes postoperatively, and the stability of the vital signs was also assessed. The results showed that using bilateral infraorbital and infratrochlear nerve block injection with 0.25% levobupivacaine for patients who underwent septorhinoplasty under general anesthesia provided greater stability of vital signs but had no effect on the pain score or analgesia need. Further assessment should be performed in a larger number of patients to either confirm or refute these results. Additional studies could be conducted in several hospitals within the Kingdom to determine how broadly applicable nerve blockade is in reducing pain sensation.
