Abstract
Oropharyngeal stenosis (OPS) is a relatively rare long-term complication of tonsillectomy in children, resulting from the narrowing of the upper aerodigestive tract between the soft palate, pharyngeal sidewalls, and base of the tongue. This is the first reported case of OPS due to significant scar hyperplasia; however, whether it is as prone to recurrence as skin scar hypertrophy remains unknown. In this article, we present the case of a 5-year-old girl who presented to our otolaryngology clinic with sleep snoring and suffocation. Her medical history included tonsillectomy and adenoidectomy, performed 3 years prior to presentation. The patient underwent a combination of surgery and administration of triamcinolone injections, resulting in significant symptomatic improvement. To date, no signs of recurrence have been reported.

Buccal Myomucosal Flap for Reconstruction of Red Lip Defects Close to Mouth Angle. J Craniofac Surg 2023; 34:e175-e178. [PMID: 35984003 DOI: 10.1097/scs.0000000000008943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Accepted: 07/09/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Owing to the special esthetic and functional role in the face, red lip reconstruction presents a challenge to plastic surgeons. Various reconstructive techniques can be employed to fix the red lip defects close to the mouth angle. The purpose of this study was to demonstrate that the buccal myomucosal flap could be an available option to repair red lip defects with preservation of its esthetics and function. METHODS A single-center, retrospective study of 7 patients with red lip defects who were treated with buccal myomucosal flap was conducted between June 2017 and March 2022. All patients were followed up for at least 6 months including questionnaires and photography. RESULTS Of these 7 patients, 2 were women, and 5 were men. The average age was 14.3 years (range, 1-32 y). All the buccal myomucosal flaps survived well. All the donor sites were closed directly without complications. The average follow-up time was 33.4 months (range, 6-57 mo). All patients were satisfied with the aesthetic and functional results. CONCLUSION The buccal myomucosal flap is versatile and reliable, with the advantages of rich vascularity, flexible design, and easy access. This study was presented to highlight that the flap could be a good candidate to treat red lip defects close to the mouth angle.

Abstract
PURPOSE This paper explores the feasibility of a new therapy for the treatment of hypospadias patients. Hypospadias is a very common congenital malformation of male genitals, with very high rate of recurrences after surgery. The field of regenerative medicine, which offers innovative solutions for many pathologies, still does not offer reliable solution for this pathology. Here, we propose quality, safety, and clinical feasibility assessment for an oral mucosa advanced therapy medicinal product (ATMP) grown on a biocompatible scaffold for a clinical study on urethral reconstruction of hypospadias patients. METHODS Urethral and oral mucosal epithelia from donor biopsies were cultivated between two fibrin layers, under clinical-grade conditions for cell and tissue characterization and comparison, aimed at tissue engineering. In addition, single-clone analyses were performed to analyze gene expression profiles of the two epithelia by microarray technology. RESULTS Oral mucosa appeared suitable for urethral reconstruction. The resulting ATMP was proven to maintain stem cells and regenerative potency. The preclinical safety studies were performed on human tissues to assess abnormalities and tumorigenicity, and confirmed the safety of the ATMP. Finally, the patient selection and the clinical protocol for the upcoming clinical trial were defined. CONCLUSIONS Against this backdrop, in this paper, we are proposing a new reproducible and reliable ATMP for the treatment of hypospadias.
