UNILATERAL CLEFT LIP/NOSE REPAIR: BARDACH'S TECHNIQUE JANUSZBARDACH, MD

Construction of the nasal floor is of great importance in unilateral cleft lip/nose repair. In my technique, this construction is achieved by creating mucoperiosteal and mucoperiochondrial flaps on the lateral nasal wall and on the nasal septum, which are then sutured together in two layers. By extending the closure anteriorly, the nasolabial fistula is also closed at the time of primary cleft lip repair. Construction of the nasal floor can be successfully achieved in narrow and medium-sized unilateral clefts. In wide clefts, where two-layer closure may be more difficult to achieve, one-layer closure may suffice. Copyright 9 1995 by W.B.

The technique for primary repair of unilateral cleft lip and nose described in this report evolved from the concepts and principles initiated by Tennison 1 and was further developed by Marcks et al, 2 Hagerty, 3 and Randall. 4 My modifications 5"6 of the technique include correction of the nasal deformity at the time of primary lip repair by constructing the floor of the nose; positioning the base of the ala so that it is symmetric with the opposite side; straightening the columella; and closure of the nasolabial fistula. Special attention is paid to constructing a deep sulcus and to properly aligning the vermilion. I do not make any incisions in the sulcus or undermine the soft tissue from the face of the maxilla. My clinical and experimental experiences have shown that incisions in the sulcus and undermining the soft tissue may be detrimental to facial growth because of extensive scarring on the anterior surface of the maxilla. Incisions in the sulcus destroy the fibrous band between the alveolar ridge at the cleft margin and the lip segment on the cleft side. In my opinion, it is necessary to preserve the fibrous band, because it helps pull the lesser maxillary segment into proper alignment. In this report, I would like to focus on construction of the floor of the nose and closure of oronasal fistulas, surgical aspects of cleft lip repair that are not always clearly presented.

PRINCIPLES OF PRIMARY CLEFT LIP/NOSE REPAIR The basic principle behind primary lip repair is to rearrange both lip segments to create symmetry in the vertical dimension on both sides. The lip height must be precisely measured to design the size and position of the triangular flap on the lesser lip segment that will be inFrom the University of Iowa, iowa City, IA.

serted into a triangular gap created on the larger lip segment. The incision that follows the design of the triangular flap allows for appropriate lengthening of the tissue on both lip segments to achieve symmetry of both sides, as well as a symmetric Cupid's bow. Reconstruction of the vermilion may require additional maneuvering because its thickness may differ in both lip segments. Special attention is paid to constructing a deep normal sulcus and to rearranging the orbicularis oris muscle from an oblique to a horizontal position. I consider correction of the nasal deformity an integral part of primary cleft lip repair. Construction of the nasal floor in two layers is achieved by suturing mucoperiosteal and mucoperichondrial flaps from the lateral nasal wall and nasal septum. By extending the closure anteriorly, the nasolabial fistula is also closed; although in very wide clefts, this may be difficult to achieve. Closure of the nasolabial fistula may remain complete or the fistula may reopen as a result of maxillary expansion during orthodontic treatment. I do not attempt to reshape or realign the lower lateral cartilage in this operation. However, I do place the base of the ala into a symmetrical position with the opposite side and thereby improve the shape of the nostril. Taking precise measurements to design the incision lines decreases the margin of error and allows for approximation of the lip segments in a proper anatomical alignment. I would like to stress that, without making incisions in the sulcus or undermining the soft tissue, lip repair can be achieved with minimal tension, even in cases of wide clefts. Most secondary deformities following lip repair using the triangular flap technique consist of an asymmetric vermilion or a notch in the vermilion. Both secondary deformities require correction.

ESSENTIAL STEPS IN CLEFT LIP/NOSE REPAIR The surgeon begins the operation by precisely measuring the height of the lip from the tips of the Cupid's b o w to the base of the columella. Both measurements are taken

from the larger lip segment. The difference between the measurements determines the length of the sides of the triangular flap to be designed on the lesser portion of the lip as well as the length of the incision, which will create the gap in the larger lip segment in which the triangular flap will be inserted. An incision is carried on the nasal septum 1 to 2 mm

above the lower edge of the septum (Fig 1). It is carried forward on the vermilion cutaneous border of the lip. With a number 11 blade, the incision is carried through the skin, muscle, and mucosa. The mucoperichondrial flap on the nasal septum is raised using a Freer knife. At the base of the columella, the orbicularis oris muscle is released from its attachment. The mucoperiosteal flap is

raised and turned downward, with the epithelium facing the sulcus. In this way, the flaps are raised inside the nasal cavity as well as on the larger lip segments. "Attention is then turned to the lateral maxillary and lip segment (Fig 2). The incision starts inside the oral cavity below the lower turbinate, in the groove between the lateral nasal wall and the palatal plate. Then the incision is carried forward along the vermilion cutaneous border, separating part of the vermilion and creating a triangular flap in the lower portion of the lip segment. With these CLEFT LIP/NOSE REPAIR: BARDACH'S TECHNIQUE

incisions completed, the mucoperiosteal flaps inside the nasal cavity are undermined. The base of the ala is mobilized, and the attachment of the orbicularis oris muscle is released. The fibrous band that extends from the alveolar ridge to the lesser lip segment is preserved. Following these preparations, closure begins as deep as is technically possible inside the nasal cavity (Fig 3). The mucoperiosteal flap from the lateral wall is sutured to the mucoperiosteal flap from the vomer and alveolar ridge. This layer not only constitutes the lower layer of

the reconstructed nasal floor b u t also closes the nasolabiaI fistula in its anterior portion. The second layer is closed by suturing the mucoperichondrial flap from the s e p t u m with the mucoperiosteal flap from the lateral nasal wall. By reconstructing the nasal floor in two layers, the alar base is approximated medially into a symmetric position. This type of reconstruction of the nasal floor is also helpful in bringing the maxillary segments into proper alignment. It also improves the position of the columella by pulling its base into the midline. After reconstructing the floor of the nose, closure of the lip starts with closure of its mucosal layer in the sulcus (Figs 4 a n d 5). It is important that the triangular flap created in the skin a n d muscle will also include the mucosa, facilitating the s y m m e t r y of the reconstructed lip (Fig 6). It is essential to create a symmetrical Cupid's bow a n d symmetrical vermilion. I use vertical mattress sutures on skin a n d muscles to avoid leaving chromic sutures in the muscles. After complete closure of the

skin, reconstruction of the vermilion m a y require some adjustments on both sides w h e n the w i d t h and thickness vary (Figs 7 a n d 8). This can be solved by transposing triangular flaps from the thicker side to the thinner so that t h e y are equal (Figs 9 a n d 10).
