Review of the Current Medical and Surgical Treatment Options for Microstomia in Patients With Scleroderma.

BACKGROUND: Most patients with scleroderma suffer from microstomia, which can have debilitating consequences on their quality of life. Unfortunately, treatment options remain limited. No specific guidelines exist; hence, microstomia remains a challenge to treat in this patient population. OBJECTIVE: This review aims to evaluate the different medical and surgical treatment modalities currently available for microstomia in patients with scleroderma and make recommendations for future research. MATERIALS AND METHODS: A search of PubMed, Ovid MEDLINE, and Ovid Embase was conducted to identify articles discussing the treatment of microstomia in scleroderma. Twenty articles discussing surgical therapy and one article discussing medical therapy were reviewed. RESULTS: Mostly because of a scarcity of high-level evidence, no individual therapy has documented long-term efficacy. Some treatments demonstrate positive results and warrant further research. CONCLUSION: Given the variability of results, specific recommendations for the treatment of microstomia in patients with scleroderma are difficult to establish. A multifaceted approach that includes surgical and medical therapy is likely the best option to improve oral aperture in this patient population. Surgical treatments such as neurotoxins, autologous fat grafting, and ultraviolet A1 phototherapy may hold the most potential for improvement.

Posterior Based Triangular Mucosal Advancement Flap for Surgical Correction of Scleroderma-Induced Microstomia.

ABSTRACT: Systemic sclerosis is a complex autoimmune connective tissue disease of unknown cause that causes sclerosis and inflammation of the skin and subcutaneous tissue. Sclerosis involving the face can lead to microstomia, leading to difficulties with mastication, phonation, and oral hygiene. Although many agents have been used to treat internal organ involvement, they often have compromised efficacy on cutaneous manifestation including facial dermal sclerosis. In this case presentation, we will introduce a surgical technique to correct scleroderma-induced microstomia.

The Importance of Dental Appliances for Oral Commissure Reconstruction in Trauma-Induced Microstomia: A Clinical Report.

Reconstruction of the oral commissure is necessary after trauma, pathological resection, or electrical, chemical, or thermal burns. Using dental appliances is strongly recommended to prevent microstomia in victims with oral commissure injury caused by burns. These appliances can be modified from dynamic to static for more patient comfort during the healing period and used in trauma patients to prevent rounding of the labial commissure. Preventing relapse of microstomia and forming acute angles at the corner of the mouth are 2 optimal goals when performing this surgery.

A comparison between two educational methods in the rehabilitation of the microstomia in systemic sclerosis: a randomized controlled trial.

OBJECTIVE: To test the effectiveness of an educational intervention including "face to face" training, compared to a standard information program, to reduce microstomia in women with systemic sclerosis. DESIGN: Single-blind, two-arm, randomized controlled study with a 12-month follow-up period. SETTING: Hospital wards of a large Italian dermatological reference center. SUBJECTS: Female inpatients with diagnosis of systemic sclerosis. INTERVENTIONS: For both groups an information brochure and an audio-visual DVD were developed specifically for the study. The control group was assigned to educational materials alone (i.e. brochures and DVD), while the experimental group, in addition to the same educational materials, received specific "face-to-face" interventions, repeated at each follow-up visit. MAIN MEASURES: Primary outcome was measurement of the opening of the mouth. Secondary outcomes was the self-reported mouth disability. RESULTS: The intention-to-treat analysis included 63 patients. Compared to the baseline measurement, we observed an increase of the mouth opening of 0.31 cm (95% confidence interval: 0.13-0.49), P = 0.003; in the control group, the increase was 0.13 cm (95% confidence interval: 0.01-0.25), P = 0.06. The difference in improvement between the two groups was not statistically significant (P = 0.10); however, it reached statistical significance in the per-protocol analysis (39 patients, P = 0.02). CONCLUSION: Face-to-face nursing rehabilitation training seems to improve microstomia to a greater extent, when compared to a standard intervention based only on written and audio-visual materials.

Impact of systemic sclerosis oral manifestations on patients' health-related quality of life: A systematic review.

BACKGROUND: Oropharyngeal features are frequent and often understated in the treatment clinical guidelines of systemic sclerosis in spite of important consequences on comfort, aesthetics, nutrition and daily life. The aim of this systematic review was to assess a correlation between the oropharyngeal manifestations of systemic sclerosis and patients' health-related quality of life. METHODS: A systematic search was conducted using four databases [PubMed® , Cochrane Database® , Dentistry & Oral Sciences Source® and SCOPUS® ] up to January 2018, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Grey literature and hand search were also included. Study selection, risk bias assessment (Newcastle-Ottawa scale) and data extraction were performed by two independent reviewers. The review protocol was registered on PROSPERO database with the code CRD42018085994. RESULTS: From 375 screened studies, 6 cross-sectional studies were included in the systematic review. The total number of patients included per study ranged from 84 to 178. These studies reported a statistically significant association between oropharyngeal manifestations of systemic sclerosis (mainly assessed by maximal mouth opening and the Mouth Handicap in Systemic Sclerosis Scale) and an impaired quality of life (measured by different scales). Studies were unequal concerning risk of bias mostly because of low level of evidence, different recruiting sources of samples and different scales to assess the quality of life. CONCLUSION: This systematic review demonstrates a correlation between oropharyngeal manifestations of systemic sclerosis and impaired quality of life, despite the low level of evidence of included studies. Large-scaled studies are needed to provide stronger evidence of this association.

Management of postburn perioral contracture using a customized static commissural splint and intralesional injections of triamcinolone.

A perioral facial burn is usually accompanied by a reduction in size of the oral orifice because of the contraction of the healing wound. Perioral contracture leads to microstomia, restricting nutrition, speech, and jaw movements and impairing the esthetic appearance of the face. It is imperative to introduce splints as early as possible to prevent the postburn sequelae. A delay in splinting allows postburn contractures. Overcoming these contractures to regain the size of the stoma requires restructuring of the hypertrophic scar using mechanical force and the biomodification of the tissues. This article describes the treatment of microstomia and the hypertrophic scarring of the perioral tissue using a novel static commissural splint with customizable components in conjunction with intralesional injections of triamcinolone. Within 6 months, the splint together with the steroid injections had helped increase the vertical opening of the mouth by 15 mm and the intercommissural distance by 16 mm.

Effects of Fat Grafting Containing Stem Cells in Microstomia and Microcheilia Derived from Systemic Sclerosis.

BACKGROUND: Systemic sclerosis (SSc) is an autoimmune disease with multisystem involvement, dominated by a general fibrosis. The early stage of the disease is associated with progressive damage to microcirculation, particularly in the respiratory tract, the gastrointestinal tract and skin. The face assumes a typical appearance characterized by microstomia (reduction of mouth opening) and microcheilia (thinning of the lips). These conditions cause a considerable reduction in performance status of patients. We treated them by fat grafting, rich in adipose stem cells, and we evaluated through time clinical, functional and aesthetic evaluation of oral pathology associated with SSc. MATERIALS AND METHOD: From September 2014 to May 2016, we enrolled and treated seven patients in the plastic, reconstructive and aesthetic surgery clinic. Through time, we evaluated the following parameters: evaluation of mouth opening (maximum opening in superior-inferior and lateral directions) and lip thicknesses, both measured by doctors of the aforementioned operating unit; variation in the quality of life as perceived by patients according to the MHISS scale (Mouth Handicap Systemic Sclerosis); variation in severity of labial fibrosis assessed by microscopic analysis of pre- and post-fat transfer samples in the pathology clinic; safety of the protocol, according to the management of side effects resulting from the procedure; aesthetic evaluation, made by external observers and non-experts in the field, on pre- and post-operative photographs. RESULTS AND CONCLUSIONS: We reported satisfying results, both functionally and aesthetically, for all parameters except one, for which the sample size might have proven critical. These data should be a starting point for further experimental research and clinical trials. LEVEL OF EVIDENCE IV: This journal requires that authors assign a level of evidence to each article.

Postburn Microstomia Prevention Using an Appliance Providing Simultaneous Horizontal and Vertical Adjustable Forces.

Microstomia, an abnormally small oral orifice, is a complication of perioral facial burns. In this case, contraction of the circumoral tissues and hypotonia of the musculature is responsible for this microstomia, which can produce aesthetic and functional impairment with eating, swallowing, communication (speech and facial expressions), compromised dental care and maintenance due to limited oral access, social interactions, and psychological well-being. Conservative management involves providing physical resistance to scar contracture, with opposing horizontal and vertical circumoral forces by means of appliances that aim to stretch the commissures and fibrotic muscles. Numerous appliances, either intraoral or extraoral, have been described to prevent or treat microstomia by delivering a static or dynamic stretch horizontally or vertically, with most designed to stretch the mouth horizontally. Finding a comfortable effective way to stretch the mouth vertically has proved to be a challenge. This article describes the fabrication of a dynamic commissural appliance, constructed using acrylic resin and expansion screws, which provide simultaneous horizontal and vertical circumoral forces. This appliance is constructed easily and inexpensively without the need for taking impressions, can be adjusted so that it is almost painlessly inserted, and is progressively activated. It is convenient for use because the patient controls the pressure that is applied by the appliance. Its use in a case is described where the appliance has improved mouth opening and consequently functional outcomes.

Using Bar and Ball Attachments in Maxillary and Mandibular Implant-Supported Overdentures in a Patient with Adenoid Cystic Carcinoma Associated with Microstomia: A Clinical Report.

Many clinical studies and literature reviews have suggested that bar and ball attachments in maxillary and mandibular implant-supported overdentures (ISOs) should be indicated only when there is sufficient interocclusal space (IOS; minimum = 30 mm). The aim of this clinical report was to present the prosthetic rehabilitation of a patient with adenoid cystic carcinoma associated with microstomia due to radiotherapy (IOS = 23 mm). ISOs offer superior retention and greater stability than conventional obturators, so that base extensions were kept to the minimum. Placing the balls parallel to the prosthesis path of insertion is much easier with this treatment modality.

Effects of intense pulsed light in microstomia in patients with systemic sclerosis: A pilot study.

INTRODUCTION: The effects of intense pulsed light (IPL) on collagen structures are well known in the treatment of photodamaged skin. OBJECTIVE: The objective of this study was to investigate the effect of IPL on sclerotic skin by treating patients with microstomia due to systemic sclerosis. METHODS AND MATERIALS: 13 patients all with microstomia and systemic sclerosis were treated with IPL, PR (530-750 nm filter) and/or VL (555-950 nm filter) applicator. They were treated in the perioral area 8 times with 3-4 weeks of interval and follow-up for 6 months. The outcomes were the inter-incisal distance and the inter-ridge distance. RESULTS: A significant increase in mouth opening of 4.1 mm (95% confidence interval, 1726-6638, p < 0.005) was found in the inter-ridge distance when comparing the distance before treatment with the distance at six-month follow-up. No significant difference was found in the inter-incisal distance. The patients experienced improved mobility and better control of lip movements after the treatments. CONCLUSION: IPL can improve the inter-ridge distance between the lips in patients with microstomia due to systemic sclerosis but does not affect the inter-incisal distance, which is also dependent on the mobility of the mandibular joints. This treatment can be considered an adjunctive therapy in patients with microstomia due to systemic sclerosis.

Management of Severe Microstomia in a Ten-Week-Old Infant.

Microstomia is rarely seen in pediatric patients, but usually results from burns, trauma, or caustic ingestions. There have been multiple studies reporting various techniques for oral commissure reconstruction, but few reports in infants. The authors present another modification of previous techniques of microstomia repair performed in a 10-week-old infant using multiple z-plasties and bilateral mucosal rhomboid flaps.

Total and near-total lower lip reconstruction: 20 years experience.

BACKGROUND: Reconstruction of total and near-total lower lip defects presents a formidable challenge for the reconstructive plastic surgeon. Many methods have been described, and each has its own advantages and disadvantages. The aim of this article is to discuss the selection of techniques and report our experience of total or near-total lower lip reconstruction. MATERIAL AND METHODS: Over a 20-year period from January 1993 to December 2013, a total of 87 patients underwent total or near-total lower lip reconstruction. Bilateral Yu's flaps were used in 61 patients, double mental neurovascular V-Y island advancement flaps in 16 patients, bilateral Mutaf's techniques in 4 patients, and reconstruction with free radial forearm flaps in 6 other patients. Drooling Rating Scale (DRS) and Patient and Observer Scar Assessment Scale (POSAS) were used to evaluate oral competency and esthetic outcomes. RESULTS: All patients underwent single-stage total or near-total lower lip reconstruction successfully. There were no flap failures. Only 1 patient who accepted the bilateral Yu's flaps developed microstomia, having difficulty in wearing her dentures postoperatively. Oral competencies were well preserved in other patients, and esthetic results were satisfactory. CONCLUSION: Based on our experience, we recommend using the bilateral local techniques or free flap introduced in this article, according to the extent of defects and the patient's general condition, to achieve a personalized ideal reconstruction of the lower lip.
