Foreign bodies lodged in the nasal cavity are a common problem in children, and their removal can be challenging. The published studies relating to the “mother’s kiss” all take the form of case reports and case series. We sought to assess the efficacy and safety of this technique.

STUDY DESIGN.: Prospective case series study. OBJECTIVE.: To study the effect of percutaneous thoracoplasty-only procedure on curve pattern in mature adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA.: The rib hump prominence on the convex side is the major cosmetic concern among patients with AIS. Thoracoplasty combined with spinal fusion is a commonly used procedure in scoliosis. However, there are no studies regarding the effect of isolated thoracoplasty procedure on curve pattern in skeletally matured patients with AIS. METHODS.: The study involved 7 skeletally matured female patients with AIS. The convex rib hump deformity was measured preoperatively using hump height and hump angle. We performed thoracoplasty without spinal fusion in patients with the Cobb angle less than 40° but with prominent hump deformity. Thoracoplasty was performed percutaneously using 1 or 2 transverse incisions along the rib hump, and apex portions of the deformed ribs were resected. The Cobb angle was measured before surgery, immediately after surgery, and at final follow-up visit. In all cases, clinical satisfaction was assessed using the Scoliosis Research Society Instrument (SRS-22 questionnaires) and trunk appearance perception scale before surgery and at final follow-up visit. RESULTS.: The mean patient age was 20.24 years and an average of 4 ribs were resected. The mean preoperative hump height and hump angle of 38.14 mm and 14.14° improved to 11.70 mm and 11.42° respectively, after surgery (P = 0.018 and 0.042). Preoperative and the final follow-up mean Cobb angles were 35.43° and 45.00°, respectively (P = 0.028). On average, the mean thoracic curve progressed by 9.57°. Preoperative Scoliosis Research Society Instrument SRS-22 questionnaires and trunk appearance perception scale scores of 4.09 and 2.57 respectively improved to and 4.26 and 3.66 after surgery (P = 0.126 and 0.014). CONCLUSION.: Percutaneous thoracoplasty-only procedure gives significant rib humps correction and satisfactory clinical outcome. However, progression of the curve was observed after surgery. This suggests that the convex ribs function as a buttress for curve progression.

Balloon dilation may offer a more expedient and cost-effective treatment method compared with traditional endoscopic sinus surgery for chronic maxillary atelectasis. We sought to demonstrate the feasibility of balloon dilation of the maxillary os as a treatment modality for patients with chronic maxillary atelectasis by investigating the short-term outcomes in a retrospective case series of 4 patients representing 5 sinuses treated between 2011 and 2013. All sinuses were successfully balloon dilated without complications. Follow-up ranged from 1 week to 4 months. Aeration of the treated sinuses without restenosis was confirmed by postoperative endoscopy, sinus computed tomography, or both. All patients reported subjective symptomatic improvement. Balloon dilation of the maxillary os may be a feasible treatment option for maxillary sinus atelectasis. Longer follow-up and a larger study sample will be needed to validate the safety of this technique and determine the rate of restenosis.

Objective: To present and evaluate the use of nasal dermoplasty for control of recurrent nasal polyps. Study design: Prospective case series. Method: The mucosa of the fovea ethmoidalis and the lamina papyracea was replaced by a split-thickness skin graft. The follow-up period ranged from 2 to 12 months. Results: Five patients underwent nasal dermoplasty for recurrent nasal polyposis. In three cases, the graft uptake was successful. Post-operatively, four patients reported they were in better condition than at the same interval after their previous operation. Recurrence of polyps was noted in all patients but not in the grafted areas. Conclusion: In this study, there was a high prevalence of successful graft uptake following nasal dermoplasty. This technique may have potential for the control of recurrent nasal polyps. Although it is demanding and time-consuming, it may reduce the need for multiple operations. Further research is justified to establish its efficacy.

The present multicenter, prospective study evaluated the subjective outcomes in patients after extraosseous talotarsal stabilization using the HyProCure(®) stent as a standalone procedure for the treatment of recurrent and/or partial talotarsal joint dislocation (RTTD) in a population of pediatric and adult patients. RTTD has been cited as a possible etiology for a number of foot ailments and might contribute to the development of pathologic features localized more proximally in the weightbearing musculoskeletal chain. Correction of RTTD might, therefore, lead to the reduction of pathologic features associated with this deformity. A total of 46 feet in 35 patients were included in the present investigation. Subjective evaluation used the Maryland Foot Score assessment, which was obtained preoperatively and 1, 2, and 3 weeks, 1, 2, 3, and 6 months, and 1 year postoperatively. The mean overall scores improved from a preoperative value of 69.53 ± 19.56 to a postoperative value of 89.17 ± 14.41 at the 1-year follow-up. Foot pain decreased by 36.97%, foot functional activities improved by 14.39%, and foot appearance improved by 29.49%. The greatest magnitude of improvement occurred 4 weeks postoperatively, with gradual improvement continuing through to the 1-year follow-up. Implants were removed from 2 patients (2 feet, 4.35%). No unresolved complications were observed. The positive subjective outcomes resulting from the extraosseous talotarsal stabilization procedure suggest that the intervention employing the device we have described alleviates pain and improves foot function and appearance in patients with RTTD.
