Perioperative management of paediatric microstomia.

Paediatric microstomia may occur congenitally in the whistling face syndrome but is more often acquired after accidental thermal injuries such as biting an electrical extension cord or ingesting household lye. The surgical correction of microstomia includes separation and cosmetic reconstruction of the fused lips and postoperative oral splinting. Microstomia from lye ingestion may be associated not only with limited mouth opening but also with such severe intraoral scarring that common landmarks guiding either rigid or flexible fibreoptic laryngoscopy are obscured, rendering oral and nasotracheal intubation difficult or impossible. We report a case of paediatric microstomia after lye ingestion in which conventional direct laryngoscopy, flexible fibreoptic laryngoscopy, and multiple blind nasal approaches to tracheal intubation were unsuccessful. However, tracheostomy was avoided and successful tracheal intubation was accomplished using a new rigid tubular pharyngolaryngoscope.

The Vancouver microstomia orthosis.

Eighteen microstomia orthoses are compared with respect to their characteristics, use, and limitations. A new prosthesis, the Vancouver microstomia orthosis, was designed to incorporate the advantages of many of the orthoses and eliminate some drawbacks. Ten adults with microstomia secondary to second- or third-degree circumoral flame burns were fitted with the prosthesis and observed over a 12-month period. In 9 weeks or less, microstomia was corrected with an average gain of 7 mm in the horizontal and 13 mm in the vertical active range of motion. The measures before and after this treatment were statistically significant for increase in both dimensions (paired t-test, p less than .01).

The microstomia prevention appliance: 14 years of clinical experience.

Partial- or full-thickness perioral facial burns may lead to a contracture of the tissues surrounding the oral commissures that results in microstomia. The current investigators have used the microstomia prevention appliance (MPA) exclusively in the management of commissure burns at the University of Iowa Burn Center since 1972. To assess the effectiveness of the MPA, a retrospective chart review was conducted. The study population consisted of 85 patients admitted to the center between 1974 and 1986 who had incurred burns to the perioral region or to the lower two thirds of the face. The chart analysis of 83 patients revealed that, with diligent and persistent use of the MPA, only one patient required surgical repair for the development of microstomia. The MPA has proved effective in decreasing the need for reconstructive procedures and in preventing the occurrence of microstomia.

Static orthoses for the management of microstomia.

Microstomia is a complication of facial burns, traumatic injuries, scleroderma, or surgical reconstructions involving the oral aperture. A variety of orthoses for the correction or prevention of microstomia are offered by dentists, occupational therapists, physical therapists, and other specialists. This paper provides an overview of the structural and clinical features of 12 common tissue-borne or tooth-borne microstomia appliances. The review is intended to facilitate the selection of suitable orthoses, and to indicate the need for interdisciplinary management of microstomia patients.

Modified microstomia prevention splint.

The modified microstomia prevention splint (MMPS) was designed to overcome burn microstomia which could not be treated by the use of conventional microstomia prevention appliances. In addition, further modifications eliminated problems of pressure on the oral mucosa. The MMPS is now the preferred splint at the Royal Brisbane Hospital Burns Unit.

Dynamic orthoses for the management of microstomia.

Oral wounds and burns may result in microstomia with significant management problems. An important early management decision involves the selection of an appliance capable of applying forces that will halt and reverse the condition. A selection appropriate to the patient may be based on the need for teeth suitably placed to retain and position a particular device. Limited access to the patient's mouth because of recent trauma, surgery, wiring, inability to tolerate anesthetic, etc., may further restrict choices. Thus, the process of selection involves a weighing of the specific patient's condition and program of treatment against an understanding of the unique features, including complexity of fabrication and durability, of the range of prostheses available. This article provides an overview of the structural and clinical characteristics of seven dynamic intraoral and extraoral microstomia appliances. The need for interdisciplinary management of microstomia with appliances has been noted, and opportunities for research have been pointed out.

Functional reconstruction for severe postburn microstomia.

A man with severe burn microstomia refractory to traditional management (Z release, skin grafting, splinting, bilateral commissuroplasty, and extensive physical therapy) is presented. Successful functional microstomia reconstruction was achieved with a three-stage approach consisting of the following: (1) lip, commissure, and cheek reconstruction with bilateral temporalis muscle transfers; (2) free flap neck and lower lip contracture release; and (3) vestibuloplasty with a stented full-thickness skin graft.

[Method of correction of microstomia and deviation of the mouth angles by rotation of trapeziform and triangular flaps of the mouth mucosa].

In the paper, the author suggests an essentially new method of dilation of the oral orifice and elimination of mouth angles deviations basing on the principle of new redistribution of local tissues by means of rotation of a trapeziform graft of the mucosa with its submucous layer from the buccal and adoral region. In this method one uses more adequate tissues, which reserves in case of microstomia are located in the buccal and adoral region. The successful utilization in 60 patients of the suggested method of elimination of microstomia arising due to different causes enabled the author to recommend it widely for reparative surgery.

Preliminary impression in patients with microstomia.

This article describes a preliminary impression technique for edentulous patients with microstomia. Stock impression trays are modified to make sectional impressions of the left and right sides of the maxillary arch. The cast poured into the first impression is positioned in the second impression, which is then poured to make the diagnostic cast.

The mandibular swing-lock complete denture for patients with microstomia.

Regardless of cause, the treatment of an edentulous patient with microstomia is difficult and often ingenious. Prosthodontic treatment modalities previously described are reviewed. A new type of prosthesis, the collapsible mandibular swing-lock complete denture, is introduced. The prosthesis incorporates a cast cobalt-chromium framework with a lingual hinge and a conventional labial swing-lock. This combination allows the prosthesis to be collapsible while maintaining structural durability. Advantages include ease of insertion and removal while providing maximum coverage for support, retention, and stability. A stepwise technique for the clinical and laboratory phases is described.

Treatment of severe microstomia caused by swallowing of caustic soda.

Treatment of severe microstomia caused by swallowing of caustic soda is presented. The oral cavity was severely constricted because of mucosal adhesions. We used a free forearm flap for reconstruction of the oral cavity and vermilion flaps at the oral commissure, with satisfactory results. A technique is presented, and the problems with respect to the reconstruction of the oral cavity are discussed.

Expanding oral angle plasty using a subcutaneous pedicle flap to correct severe microstomia after extensive facial burns.

Expanding oral angle plasty using a subcutaneous pedicle flap to correct severe microstomia due to extensive facial scar contractures is described. This technique is especially suited for the elderly, who are unable to tolerate large skin grafting of the face, and for patients with insufficient normal donor skin to undertake extensive correction of scar contractures.

An intraoral splint for the prevention of microstomia from facial burns.

Microstomia may be a disfiguring complication of severe burn injuries of the soft tissues of the face. The constriction of the perioral myocutaneous tissues following such trauma poses several problems and usually necessitates major plastic and reconstructive intervention. A novel technique is described which limited the anticipated constriction of perioral tissues in a 21-year-old female who suffered full skin thickness burns to 65 per cent of her body, including her face, following a self-induced petrol burn.
