Important Notice

PubMed Central Canada to be taken offline in February 2018

On February 23, 2018, PubMed Central Canada (PMC Canada) will be taken offline permanently. No author manuscripts will be deleted, and the approximately 2,900 manuscripts authored by Canadian Institutes of Health Research (CIHR)-funded researchers currently in the archive will be copied to the National Research Council’s (NRC) Digital Repository over the coming months. These manuscripts along with all other content will also remain publicly searchable on PubMed Central (US) and Europe PubMed Central, meaning such manuscripts will continue to be compliant with the Tri-Agency Open Access Policy on Publications.

1.  Unilateral Recurrent Laryngeal and Hypoglossal Nerve Paralysis Following Rhinoplasty: A Case Report and Review of the Literature  
Introduction:
Injury to cranial nerves IX, X, and XII is a known complication of laryngoscopy and intubation. Here we present a patient with concurrent hypoglossal and recurrent laryngeal nerve paralysis after rhinoplasty.
Case Report:
The patient was a 27-year-old woman who was candidate for rhinoplastic surgery. The next morning after the operation, the patient complained of dysphonia and a sore throat .7 days after the operation she was still complaining of dysphonia. She underwent a direct laryngoscopy, and right TVC paralysis was observed. Right hypoglossal nerve paralysis was also detected during physical cranial nerve function tests. Hypoglossal and recurrent laryngeal nerve function was completely recovered after 5 and 7 months, respectively, and no complication was remained.
Conclusion:
Accurate and atraumatic intubation and extubation, true positioning of the head and neck, delicate and gentle packing of the oropharynx, and maintenance of mean blood pressure at a safe level are appropriate methods to prevent this complication during anesthesia and surgical procedures.

2.  The Effect of Local Injection of Epinephrine and Bupivacaine on Post-Tonsillectomy Pain and Bleeding 
Introduction:
Tonsillectomy is one of the most common surgeries in the world and the most common problem is post-tonsillectomy pain and bleeding. The relief of postoperative pain helps increase early food intake and prevent secondary dehydration. One method for relieving pain is peritonsillar injection of epinephrine along with an anesthetic, which has been shown to produce variable results in previous studies. Study Deign: Prospective case-control study. Setting: A tertiary referral centers with accredited otorhinolaryngology-head & neck surgery and anesthesiology department.
Materials and Methods:
Patients under 15 years old, who were tonsillectomy candidates, were assigned into one of three groups: placebo injection, drug injection before tonsillectomy, and drug injection after tonsillectomy. The amount of bleeding, intensity of pain, and time of first post-operative food intake were evaluated during the first 18 hours post operation.
Results:
The intensity of pain in the first 30 minutes after the operation was lower in the patients who received injections, but the difference was not significant during the first 18 hours. The intensity of pain on swallowing during the first 6 hours was also lower in the intervention groups as compared with the placebo group. The amount of bleeding during the first 30 minutes post operation was lower in the two groups who received injections, but after 30 minutes there was no difference.
Conclusion:
Injection of epinephrine and bupivacaine pre- or post- tonsillectomy is effective in reducing pain and bleeding. The treatment also decreases swallowing pain in the hours immediately after surgery.
