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).

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.

An appliance to prevent and treat microstomia from burns.

The development and use of a dynamic splint, Microstomia Prevention Appliance, is described. It is effective in preventing microstomia as a consequence of burns and is capable of enlarging a contracted mouth if used before maturation of the scar.

[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.

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.

[Agnathia, microstomia, synotia].

The authors describe a case of plurimalformative syndrome, characterized by agnathia, microstomia, synotia and by cardiac and pulmonary maldevelopment. The case peculiarity consist in the rarity of this malformative occurrence; moreover, the authors underline the occurrence of familiarity with Seckel's Syndrome.

In utero diagnosis of agnathia, microstomia, and synotia.

A rare case of the in utero observation of agnathia, microstomia, and synotia associated with hydramnios is presented. The correct diagnosis is made by observing an absent mandible in a patient with hydraminios.

Surgical management of microstomia in the dental office.

Scarring of the oral stoma is usually a consequence of burns of the circumoral region. The subsequent contractural decrease in the width and general size of the opening is deforming, interferes with eating, makes dental treatment extremely difficult, prevents access for oral hygiene, and makes general anesthesia hazardous. A case report demonstrates the relative ease and safety of performing a commissurotomy in the dental office with local anesthesia alone so that access is facilitated and the dentition of these patients can be rehabilitated.

[The problem of taking dental impressions in acquired microstomia].

Two cases of severe cicatricial atresia of the oral rima with total edentia are reported. These patients present considerable problems when impressions of the dental arches have to be obtained. To make the labial tissues more elastic and in the attempt to increase rimal space, a perilabial collar of resin is made. Using the normal silicon-based synthetic elastomers, a first mould can be obtained directly in the mouth. This in its turn is filled with a more fluid elastic material and set in the mouth. From this initial impression, a chalk model can be obtained and from this an individual silicon mould is made from which a more accurate final impression is possible. In order to adjust the occlusion and test the teeth, a resin plate is prepared. This can be detached from the wax and fitted into the mouth. The standard methods are then employed to make the body of the prosthesis.
