RESUMEN
Background Although choanal atresia (CA) was first described 250 years ago, its description and understanding remain incomplete, as is the distinction between unilateral and bilateral CA. Among the surgical techniques introduced to manage this condition are intranasal Hegar's dilator (IHD) and transnasal endoscopic excision (TNEE). Objectives This study retrospectively evaluated the outcomes and effectiveness of IHD and TNEE in the treatment of patients with CA, including differences in the incidence of re-stenosis with these techniques. Methods Patients diagnosed with CA who underwent surgical interventions in the Otolaryngology Department of Al-Noor Specialist Hospital, Makkah, Saudi Arabia, between 1997 and 2017 were analyzed. Postoperative outcomes including re-stenosis rates were compared in patients who underwent IHD and TNEE. Factors associated with patient outcomes were analyzed, including ages at diagnosis and surgery, nationality, gender, type of atresia (unilateral/bilateral and bony/membranous/mixed), surgical intervention (IHD or TNEE), and re-stenosis and need for revision surgery after IHD and TNEE. Results A total of 30 patients were diagnosed with CA, including 21 (70%) girls and 9 (30%) boys. Of them, 18 (60%) patients were diagnosed at younger than one month of age, 28 (93%) were Saudi nationals, and 20 (67.70%) were aged younger than three months at the time of surgery. Of these 30 patients, 17 (56.70%, all Saudi nationals) underwent IHD, and 13 (43.30%), including 15 Saudi nationals, underwent TNEE. The 17 patients who underwent IHD included 13 (76.50%) girls and 4 (23.50%) boys, whereas the 13 patients who underwent TNEE included 8 (61.50%) girls and 5 (38.50%) boys. Fifteen patients (50%) had mixed-type CA, nine (30%) had bony-type CA, and six (20%) had membranous-type CA. Twenty-six (86.67%) patients underwent primary surgery, whereas four (13.33%) underwent revision surgery; of the latter, three (75%) had undergone primary IHD, and one had undergone primary TNEE. Only one (3.33%) patient experienced re-stenosis after revision surgery, which consisted of IHD. Twelve patients (40%) underwent stenting, with one developing re-stenosis. The relationships between surgical approach and re-stenosis after primary and secondary surgery were not statistically significant. Conclusion The outcomes in patients with CA treated with IHD and TNEE are comparable. Rates of re-stenosis and need for revision surgery do not differ significantly in patients treated with these surgical approaches.
RESUMEN
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.
