We present a cohort review of TORS resection for HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) and its associated oncological outcomes spanning a 10-year period. A retrospective case series review was performed of patients undergoing primary surgical treatment for HPV-associated OPSCC through the St. Vincent's Head and Neck Cancer service from 2011 to 2022.

Methods: A retrospective cohort review was performed on 110 HPV-positive oropharyngeal carcinoma patients who underwent transoral robotic surgery and bilateral neck dissections from 2012 to 2022. The primary outcome was to investigate the pathological incidence and location of contralateral neck node metastasis.
Background: Transoral robotic surgery (TORS) is an emerging minimally invasive surgical treatment for residual, recurrent, and new primary head and neck cancers in previously irradiated fields, with limited evidence for its oncological effectiveness.
Methods: A retrospective observational cohort study of consecutive cases performed in 16 high-volume international centers before August 2018 was conducted (registered at clinicaltrials.gov [NCT04673929] as the RECUT study).
Background: Human papilloma virus (HPV)-associated oropharyngeal squamous cell carcinoma (OPSCC) continues to increase in incidence. Patients are younger, non-smokers and most commonly present with a neck mass often with no other symptoms. This altered presentation compared with non-HPV OPSCC may not be recognized by medical practitioners, leading to delayed diagnosis.

The method used was the clinical case of a patient presenting with an anteriorly based tumor in the left submandibular space. The video shows the transoral robotic technique for access to the submandibular space through the parapharyngeal space for removal of the tumor.

- Frontal sinus osteomas are benign tumors with a male predominance, primarily causing symptoms like pain and sinonasal issues.
- Recent literature shows a shift toward endoscopic surgical methods, which are less invasive than traditional open surgery, with significant reductions in complications and hospital stays.
- Complete removal of the osteoma is crucial, as it greatly reduces the risk of recurrence, highlighting the advancements in surgical techniques and understanding of these conditions over the last 30 years.
Introduction: Chronic maxillary atelectasis (CMA) is a rare acquired condition of persistent and progressive reduction in maxillary sinus volume and antral wall collapse secondary to ostiomeatal obstruction and development of negative intra-sinus pressure gradients.
Case Presentation: A 32-year old male was referred with a 6 week history of persistent and worsening sinonasal symptoms, following a significant upper respiratory tract infection. Imaging confirmed bilateral stage I CMA and successful treatment entailed bilateral endoscopic uncinectomy and maxillary antrostomy.
Background: Deep sternal wound infection (DSWI) is a rare but severe complication following cardiac surgery. Our study investigated the risk factors and treatment options for patients who developed DSWI at our institution between May 1988 and April 2008.
Method: Data was collected prospectively in a database and information on demographics reviewed retrospectively on 5649 patients who underwent cardiac surgery during this period.
