Objectives: The aim of the present study was to assess greenhouse gas emissions for the main current subtotal tonsillectomy techniques.
Materials And Methods: A retrospective study was conducted in 2 French university hospital pediatric ENT departments in 2022. The target techniques were radiofrequency with single-use or reusable needle, coblation, and dissection by cold instruments or by bipolar forceps. The medical devices required by each technique were listed and respective greenhouse gas emissions (carbon footprint, in kg eCO) were calculated, according to weight, energy consumption and place of production.
Results: Coblation generated a carbon footprint of 8.6kg eCO, versus 0.1-0.2kg eCO for the other techniques.
Conclusion: Greenhouse gas emissions in subtotal tonsillectomy differ greatly according to technique. Bipolar dissection and radiofrequency have a smaller footprint than coblation. This type of data, which needs to be weighed over time according to medical benefit, should be systematically taken into account in choosing hardware for surgery.

Article Synopsis
- A 54-year-old male with a history of tobacco use faced recurrent squamous cell carcinoma (SCC) of the tonsil, first requiring surgery for the left tonsil.
- Despite initial treatment, SCC reappeared in the right tonsil and spread to other areas, necessitating further invasive surgeries like total laryngectomy.
- The study highlights the importance of advanced imaging, robotic-assisted surgeries, and a multidisciplinary approach for effectively managing complex cases of oropharyngeal SCC.
Total versus subtotal tonsillectomy for recurrent tonsillitis: 5-year follow up of a prospective randomized noninferiority clinical trial.

Purpose: In long-term follow-up, it remains uncertain whether tonsillectomy, a procedure associated with significant comorbidity, can be substituted with partial tonsillectomy in patients with recurrent tonsillitis. This paper is to present the 5-year follow-up data of our previous study titled "Total versus subtotal tonsillectomy for recurrent tonsillitis-a prospective randomized noninferiority clinical trial."
Materials And Methods: The underlying study was performed as single-blinded prospective noninferiority procedure in patients with recurrent chronic tonsil infection, where one side was removed completely (tonsillectomy) and the other side partially (intracapsular/partial tonsillectomy).

A Diagnostic Challenge: Toxoplasmosis Masquerading as Tonsillar Neoplasm.

April 2024
Department of Otolaryngology, Head and Neck Surgery, Bnai-Zion Medical Center, Haifa, Israel.
This case report elucidates an uncommon manifestation of toxoplasmosis characterized by an ulcerative oropharyngeal lesion and cervical lymphadenopathy, which intriguingly simulated a tonsillar neoplasm. The patient, a 28-year-old immunocompetent woman, reported symptoms such as a persistent sore throat, unilateral neck pain, and otalgia. Despite the initial clinical impressions, a diagnostic left subtotal tonsillectomy revealed no malignancy but marked acute and chronic inflammation.

Objectives: to compare safety and long-term symptoms after TE compared to Subtotal Tonsillectomy (STT).
Methods: A retrospective review data of 412 patients, one to twelve years old that underwent either TE or STT, as treatment for sleep disorder breathing, at two different medical centers. Symptoms were assessed by a questionnaire 3-5 years post-surgery.
