Spontaneous Retropharyngeal and Mediastinal Emphysema.

Clin Exp Otorhinolaryngol 2016 Jun 19;9(2):178-81. Epub 2016 Apr 19.

A 14-year-old girl with no significant medical history presented at Emergency Department with sore throat and odynophagia after one episode of nonviolent coughing. She denied any respiratory distress, voice change, foreign body ingestion, retching, substance abuse, dental procedures, or trauma. She was afebrile with normal oxygen saturation and physical examination including the head and neck was unremarkable with the exception of bilateral neck crepitus without tenderness on palpation. Fiberoptic laryngoscopy revealed a patent laryngeal airway with normal vocal fold movement. Lateral neck X-ray demonstrated a linear air-column in the retropharyngeal space and computed tomography confirmed emphysema involving the retropharyngeal space and mediastinum with no evidence of fluid collection or abscess formation. Spontaneous retropharyngeal and mediastinal emphysema are clinical entities where free air is present within the confines of retropharyngeal space and mediastinum without obvious cause. It is benign and self-limited in nature and allows for conservative management. This case is presented with a review of literature.

Perioperative steroids in tonsillectomy using electrocautery and sharp dissection techniques.

Arch Otolaryngol Head Neck Surg 2004 Aug;130(8):917-21

Department of Otolaryngology--Head and Neck Surgery, Stanford University Medical Center, Stanford, CA, USA.

Objective: To determine the effect of preoperative dexamethasone sodium phosphate administration on posttonsillectomy morbidity for electrocautery ("hot") and sharp ("cold") dissection techniques.

Design: Prospective, randomized, double-blind study.

Setting: University pediatric hospital and county teaching hospital. Subjects A total of 219 children, aged 9 months to 12 years, undergoing tonsillectomy. Intervention Participants who underwent tonsillectomy were randomly assigned to receive either intravenous dexamethasone sodium phosphate (1 mg/kg) or placebo.

Outcome Measures: Pain scores, oral intake, and emesis on postoperative day (POD) 1.

Results: A total of 106 subjects (62 undergoing hot and 44 cold tonsillectomies) received preoperative steroids, and 113 (56 hot and 57 cold tonsillectomies) received placebo. On POD 1, pain scores reported by patients (P =.02), parents (P =.002), and physicians (P<.001) were significantly lower in subjects receiving steroids than in those receiving placebo. Emesis was reduced from a mean of 2.1 (placebo group) to 1.2 episodes (steroid group) (P =.02). Oral intake improved from 24.5% of normal diet (placebo) to 31.7% (steroid group) (P =.004). When all 4 groups were compared (cold placebo, cold steroid, hot placebo, and hot steroid), pain scores reported by physicians and parents were significantly lower in the cold steroid group than in the other groups.

Conclusions: Perioperative dexamethasone use reduces posttonsillectomy morbidity in pediatric patients in the early postoperative period after hot or cold tonsillectomy. The combination of steroid and cold dissection technique provided the greatest advantage in reducing posttonsillectomy subjective pain levels.
