NCT ID: NCT03392272 Not yet recruiting - Clinical trials for Surgical Procedure, Unspecified

Modified Müller's Muscle-conjunctival Resection Internal Ptosis Repair Using Fibrin Glue

Start date: February 1, 2018
Phase: N/A
Study type: Interventional

Fibrin glue is widely used in ophthalmology for homeostasis and tissue recovery. It is commonly used in ocular surface surgeries such as pterygium removal and conjunctival lesions excisions. In Müller's muscle-conjunctival resection (MMCR), sutures are used to reconnect the conjunctiva and Muller muscle, which causes discomfort and pain for the patient. The investigators' goal is to explore using fibrin glue instead of sutures in MMCR surgeries to shorten the procedure's length and alleviate patients discomfort and pain. This is especially important in the management of children suffering ptosis, where sedation and even general anaesthesia is required for sutured removal as a secondary procedure.

Aesthetic and Functional Results of Alar Base Modifications in Rhinoplasty

Start date: September 15, 2017
Phase: N/A
Study type: Interventional

Rhinoplasty is among the most accomplished aesthetic procedures in Plastic Surgery. The mastery of Alar Base modifications is essential for superior aesthetic results. The main indication is to reduce nasal width when it exceeds the intercanthal distance in Caucasian women. Other indications are the modification of the shape of the nostrils or to reduce alar flare in noses with too convex alar base. Since Wier's first description, a series of techniques has been developed with a common goal of making the basal view of the nose close to an equilateral triangle. The location and amount of tissue to be removed will be according to the preoperative or intraoperative indication due to changes in the alar base resulting from reductions in the projection of the nasal tip. One of the controversies in the literature is in the position of the incision in alar base modifications. Some authors prioritize incisions that do not violate the alar facial groove , since the groove region presents a greater number of sebaceous glands, leading to poor scarring results. Other authors have argued that incisions above the sulcus have caused more evident scars, anda that poor healing results would be more associated with aggressive resections of border and bad closing skin techniques. Due to divergence in the literature, the present study aims to compare, through a double blinded randomized clinical trial, two techniques of alar base modifications that will differentiate only by violating or not the alar facial groove.

Functional Nasal Surgery at the Time of Le Fort I Osteotomy: A Prospective, Single-blind, Randomized Trial

Start date: June 2013
Phase: N/A
Study type: Interventional

Objectives: The aims of this study are (1) to define the effectiveness of functional nasal surgery during Le Fort I osteotomy on nasal obstruction through objective as well as subjective evaluations, (2) to determine guideline for concomitant functional nasal surgery with Le Fort I osteotomy, and (3) to explore possible mechanisms by which functional nasal surgery may reduce nasal obstruction severity. Design: A prospective, single-blnd, randomized trial. Setting: Chang Gung Craniofacial Center and Department of Otolaryngology (ENT). Patients: A total of 80 Taiwanese patients with unilateral cleft lip and palate and dentofacial deformity (age >16 for females, >18 for males; 40 in experimental and 40 in control groups) Interventions: In the experimental group, all patients will receive Le Fort I osteotomy and septoplasty. In the control group, all patients will receive Le Fort I osteotomy only. Measurements: All patients will undergo history taking, clinical examination, radioallergosorbent (RAST) examination (before surgery), standard questionnaire and image examination before surgery, one week, 1, 3, 6, 12 and 24 months after surgery. To reduce radiation exposure, cone-beam CT will only be performed before surgery and one week, 12 and 24 months after surgery. Data Analysis: Independent t and chi-squared tests, correlation coefficients and repeated measures analysis of variance (ANOVA) will be used. Statistical significance is assumed for a p value of less than 0.05. Key Words: cleft lip palate, nasal septum deviation, Le Fort I osteotomy, septoplasty, effectiveness

Postoperative Nasal Irrigation Using Mucolytic Agents

Start date: June 2012
Phase: N/A
Study type: Interventional

Nasal irrigation techniques have been used for many years and been shown to improve symptoms of rhinosinusitis. Although there is a wealth of literature available, establishing treatment protocols can be difficult because of the great variability in recommended composition (seawater or hypertonic or isotonic saline with or without additives) and irrigation technique (variations in pressure and volume). Nasal irrigation is also used in many centers as part of postoperative treatment protocols and in particular has been recommended following endoscopic sinus surgery (ESS). Nasal crusting and thick nasal discharge have a negative impact on these patients quality of life (QOL). At the time of our study, there are no studies comparing irrigation with mucolysis with saline irrigation following ESS. The investigators aimed to assess whether mucolysis is effective at improving patients QOL and reducing postoperative signs as assessed endoscopically.
