The aim of the study was to study different patterns of congenital nasal clefts and different methods of their management trying to put forward a road map for their treatment.
Because of the rarity of atypical facial clefts, little is written with respect to patterns and plans of management. This study will spot light on atypical facial clefts affecting the nose (atypical nasal clefts) with respect to different patterns and plans of management.
Patients and methods
This was a retrospective and short prospective study that was conducted in the Department of Plastic Surgery, Menoufia University, from 2001 to 2014. The study included 26 patients with atypical nasal clefts. Those patients were classified according to Tessier classification into Tessier type 0, 1, 2, and 3. All patients were evaluated for the type of facial clefts, pattern of nasal involvement, and associated congenital anomalies. In all, 20 of them underwent surgical repair in one or more stages according to complexity of the deformity. The study describes different plans of reconstruction used for management.
The statistical analysis of data was descriptive and focused on description of different patterns of Tessier type. It showed that the highest incidence was Tessier 0, which included 17 cases found in eight patterns, followed by five cases in Tessier 1 in three patterns, two cases in Tessier type 2 in two different patterns, and two cases in Tessier type 3 in two patterns. The analysis of data showed that the most common associated congenital anomalies were cleft lip and hypertelorism. With respect to management, analysis of data showed the variation in number of operations, timing of first operation, and type of surgical intervention according to complexity and pattern of deformity.
Atypical nasal clefts can be found in a very wide range of patterns, ranging from simple esthetic deformity to complete agenesis or bifidity of the nose. Management of these cases requires good analysis of the pattern of nasal cleft and we provided a treatment algorithm for each pattern.

| Introduction|| |
Congenital clefts of the nose whether isolated or associated with more severe craniofacial clefts are fortunately rare; hence, not surprisingly, little is written with respect to operative management in long run and follow-up in patients with nasal clefts. The exact incidence of rare craniofacial clefts is unknown. However, they have been estimated at 1.4-4.9 per 100 000 live births. Comparing rare craniofacial clefts with common clefts, their incidence seems to approximate 9.5-34 per 1000 . Several theories have been proposed to explain the etiology of facial clefts. The most widely accepted theory at this time is the mesodermal penetration theory, which states that clefts occur along potential lines of fusion as lack of mesodermal penetration. Without this reinforcement, epithelial breakdown and separation occur .
The most widely accepted classification of craniofacial clefts is Tessier classification, which is proposed by Paul Tessier in 1976 [Figure 1]. This classification is based on specific axes (0-14) along the face and the cranium. The orbit divides the cranial clefts (9-14) from facial clefts (0-7), and facial clefts have cranial extensions. Tessier clefts involving the nose are types 0, 1, 2, and 3 with their cranial counterparts . Patterns of nasal clefts are very variable ranging from simple notch or asymmetry of alar margin to complex complete craniofacial cleft involving the lip, nose, eyelid, brow, forehead, and underlying bones .
Because of its rarity, there are no established standardized methods for correction of congenital nasal clefts, and management is tailored for each case using the basic principles of management. Principles of management include precise clinical and radiographic diagnosis. One must first know the normal anatomy and the sense of proper facial proportions and landmarks . Each component of the nose, skin, mucous lining, and support (both bony and cartilaginous) must be evaluated in a qualitative and quantitative manner. Staged reconstruction of patients with complex craniofacial clefts frequently requires multiple-staged reconstructive procedures. Replace like with like, for example, bone defects repaired with bone grafts (calvarial, rib, ilia, etc.). Free cartilage grafts or chondromucosal flaps are used to repair cartilage defects according to size. Adequate nasal lining is also essential to achieve functional and predictable esthetic units; in addition, optimal lining will help vascularity of reconstructed area for small area. Local mucosal flap can be used for larger defects and mucoperichondrial grafts can be used .
Hence, the aim of this work was to study different patterns of congenital nasal clefts and different methods of their management trying to put forward a road map for their treatment.
| Patients and methods|| |
This was a retrospective and short prospective study that was conducted in the Department of Plastic Surgery, Menoufia University, to study patterns of congenital nasal clefts and different modalities of management. The study included 26 patients who attended our Plastic Surgery Clinic over the period from 2001 to 2014. Inclusion criteria included atypical facial clefts involving the nose (Tessier types 0, 1, 2, and 3) [Table 1]. Exclusion criteria were other congenital nasal deformities such as common cleft lip nasal deformities and maxillonasal dysplasia and other noncongenital nose deformities such as traumatic or neoplastic. The patients were divided into four groups according to the Tessier classification as shown in [Table 1].

All patients were evaluated for type of facial cleft, pattern of nasal involvement, and associated anomalies. In all, 20 of them underwent repair of nasal cleft and associated anomalies if present in one or more stages according to complexity of the deformity.
Clinical evaluation included detailed history including perinatal history and analysis of patient's complaint (or his guardian) to determine whether the problem is esthetic only or functional and esthetic. Family history was also taken to detect similar conditions in the family. Clinical examination included general examination to detect associated congenital anomalies. Local examination included description of nose deformity at level of dorsum (either absent, hypoplastic, broad, or bifid), alae (absent, hypoplastic, depressed, notched, or widely separated), tip (absent, broad, or bifid), septum (absent, hypoplastic, depressed, or bifid), and columellar (absent, depressed, or bifid). The study describes also the associated congenital anomalies such as cleft lip, cleft palate, hypertelorism, and so on. Investigations by radiological examination were performed by three-dimensional computed tomography to assess nasal bones, facial bony clefts, alveolar clefts, or hypertelorism. Other radiological investigations were performed to detect associated congenital anomalies such as echocardiography. Routine laboratory investigations were also performed to assess patient's general condition.
Number of operations and type of surgical intervention vary widely according to pattern and complexity of the deformity. Surgical intervention aims for restoration of nasal skeleton, both bony and cartilaginous, skin coverage, and mucous lining to regain normal nasal structure giving normal esthetic look and normal function (airway).
Restoration of skin coverage was performed by either local flaps (V-Y or Z plasties), expanded forehead flap, or skin trimming and refashioning. The planning of skin flap depends on the amount of skin needed for skin coverage and mucous lining aiming for moving skin from areas of excess to areas of deficiency. Reconstruction of nasal bone was performed by either bone graft or medialization of bifid nasal bone during hypertelorism repair. The preferred donor site for bone graft in this study was iliac bone graft due to its easy harvesting, hidden donor site, and bulkiness. The harvested bone graft was shaped according to pattern of deformity as in cases of absent the bone graft shaped as pyramidal shape of nasal bone. Cartilaginous framework was reconstructed by cartilage grafts either costal or conchal according to the amount of cartilage needed and site to be positioned in - for example, if rigid cartilage is needed for columellar strut costal cartilage is used and if rim of cartilage is needed for alar shaping conchal cartilage can be used. Mucous lining was restored using folding of local skin flaps. In each operation, usually reconstruction of one or more elements is performed. Repair of associated congenital anomalies was performed side by side to repair nasal clefts - for example, repair of cleft lip or hypertelorism.
In the study, we spot light also on the management of hypertelorism associated with atypical nasal cleft because it is considered a stage in management of atypical nasal cleft. In this study, we used two methods for hypertelorism repair. The first is orbital translocation, which is performed through bicoronal incision, dissection to expose both orbits followed by osteotomy of all four walls of both orbits, and repositioning of the orbits is then performed. During this repair, correction of the bifid nasal bones is performed [Figure 4].
The second method is orbital medialization, which is performed also through bicoronal incision and dissection to expose both orbits followed by osteotomy only of the interorbital segment followed by medialization of two medial orbital walls and repositioning of the interorbital segment to decrease interorbital distance. In addition, correction of bifid nasal bones is performed during this repair [Figure 3].
Follow-up of the patients was performed over a period of 6 months from the last operation. It included guarding against complications of nose or donor site, such as hemorrhage and infection. Assessment of results was performed esthetically by patient's and doctor's satisfaction and functionally by assessment of patent nostril airways.
| Results|| |
The data from the 26 patients were either collected retrospectively from hospital records, photographic records, and patient's history or collected prospectively by clinical assessment, surgical management, and follow-up of the patient. These data underwent statistical analysis descriptive type.
The statistical analysis included the incidence with respect to the sex and presence of risk factors such as perinatal problems or drug intake. Thereafter, we come to study patterns of atypical nasal clefts after the patients were divided according to Tessier classification into Tessier 0, 1, 2, or 3. Each type was studied with respect to patterns of nasal cleft; each pattern describes the deformities present in dorsum, tip, septum, alae, and columellar [Table 2]. The study also spots light on associated congenital anomalies and their incidence.
The methods of surgical intervention were classified into skin management, and we describe different methods used to deal with skin deficiency or excess, bone management to describe options used to restore bony skeleton, cartilage management also to restore cartilaginous framework, and options for providence of mucous lining was needed. Finally, it also included the surgical intervention for associated congenital anomalies. Follow-up results were esthetically with respect to patient's satisfaction and doctor's satisfaction and functionally by patency of nostrils.
The plan of management differs according to the pattern of nasal cleft. The treatment algorithm described in [Table 3] describes the management plan for each pattern of congenital nasal cleft [Figure 2],[Figure 5],[Figure 6],[Figure 7] and [Figure 8].

| Discussion|| |
Congenital craniofacial clefts are abnormal disfigurements of the face and cranium with deficiencies, excesses, or even a normal (but separated) amount of tissue occurring along linear regions. Of all congenital facial anomalies, craniofacial clefts are among the most disfiguring. They may be seen in a variety of patterns and varying degrees of severity . In the largest series reported, Ortiz Monasterio  reviewed 6500 clefts treated over 20-year period; only 2.2% (146 patients) had nasal clefts corresponding to types 0, 1, 2, and 3 of Tessier classification, distributed as follows: 92 patients had Tessier 0 (63%), 16 patients had Tessier 1 (10.9%), 23 patients had Tessier 2 (15.7%), 15 patients had Tessier 3 (10.3%).
In this study that was conducted in Menoufia University Hospital over 11 years (2003-2014), the incidence of atypical nasal clefts (including Tessier 0, 1, 2, and 3) was 26 cases, whereas the average incidence of all craniofacial clefts was 495 cases during the period of study. This means that incidence of atypical nasal clefts is 5.2% .
The 26 cases of atypical nasal clefts were divided according to Tessier classification as follows: 17 cases in the Tessier 0 group, five cases in the Tessier 1 group, two cases in the Tessier 2 group, and two cases in the Tessier 3 group. The study showed that 34.6% of the studied group was men and 65.4% was women. The study showed some risk factors during perinatal period; five cases gave history of drug intake (three analgesics and two vitamins), two cases gave history of prolonged labor, and three cases had similar conditions in the family. The majority of cases showed no definite etiology during perinatal period.
The study showed that each type of Tessier clefts has variable patterns as follows: in Tessier 0 there were group were 17 cases. They showed the following variation: two cases of broad tip only, three cases of broad bifid dorsum and depressed flattened alae associated with hypertelorism, two cases of hypoplastic bifid dorsum, three cases of bifid dorsum and separated hypoplastic alae, one case of hypoplastic bifid dorsum and frontoethmoidal meningocele, one case of absent nasal bone with normal tip and alae, and two cases of absent nasal bone with hypoplastic widely separated alae. In Tessier 1 group there were five cases, which varied as follows: two cases of notch in medial 1/3 of alae with normal dorsum, one case of notch in medial 1/3 of alae with hypoplasia of ipsilateral dorsal bone, and two cases notch in medial 1/3 of alae with broad dorsum. Tessier 2 group included two cases, one of them had hypoplasia involving one alae and ipsilateral dorsum with notch in middle 1/3 of alae and the other case had hypoplasia of one alae and ipsilateral dorsum. Tessier 3 group included two cases, one of them showed absent one side of nose and the other case showed complete hypoplasia of one side of nose [Table 2].
The incidence of associated congenital anomalies in the cases under study was:
- Associated typical clefts: seven cases had cleft lip, four cases had cleft palate, and five cases had alveolar clefts;
- Associated eye anomalies: unilateral anophthalmia in one case;
- Other craniofacial skeletal anomalies: hypertelorism (in eight cases), frontal bone hypoplasia (in one case), bone defect with meningocele (in four cases); and
- Eyelid defects: epicanthal fold (one case), coloboma of medial 1/3 of eyelid (in three cases), and ptosis (in two cases).
The number of operations ranges according to complexity of the deformity, associated congenital anomalies, and patient and doctor satisfaction. The number of operations ranges from 1 to 7 (during the period of study); the mean number of operations was 2.35 for atypical nasal cleft repair. Timing of first operation ranges from 2 to 18 years according to severity of the deformity and patient complaint. For example, patients with bone defect absent or hypoplastic management initiated early during first 5 years of life in form of bone graft to expand the nasal skin to allow further modeling and reconstruction of nose.
After determining the type and form of deformity, we decide the plan of management and sequence of reconstructive steps; the goals of reconstruction are to restore the normal esthetic anatomy and normal function of the nose; the reconstruction involves skeletal framework of the nose (bony or cartilaginous), skin coverage, and mucous membrane lining. Repair of congenital nasal clefts cannot be performed regardless of associated anomalies such as hypertelorism or cleft lip. For example, in repair of hypertelorism the medialization of nasal bone is performed, which is considered an important step in repairing nasal cleft.
Types of interventions for skin reconstruction were in the form of local flaps in seven cases, as V-Y flap in three cases, and Z plasties in four cases. These flaps are designed to move skin from areas of skin excess to areas of skin deficiency. In cases in which the skin deficiency is large as in cases of anaplasia of half nose (Tessier 3), the repair of skin management is performed by expanded forehead flap, which was performed in two cases. Inner lining can be made by folding of local flap used for skin coverage in two cases or folding of forehead flap in two cases. Nasal bone cleft may be in the form of anaplasia or hypoplasia, if one or both nasal bones or bifid nasal bones or hypoplastic and bifid nasal bones are present. In cases with bone defect either hypoplasia or anaplasia, bone grafts were performed in seven patients. We preferred in all the seven cases the donor to be iliac bone as it is characterized by bulkiness and hardness so that the harvested bone segment can be easily modeled to take the desired shape for missed bone from the nose. In addition, harvesting iliac bone graft is characterized by easy access and hidden scar. In cases with bifid nasal bone without hypoplasia, the deformity can be corrected with medialization of nasal bone and there is no need for bone graft, and if this is associated with hypertelorism the medialization of nasal bone is considered a step in hypertelorism repair operation. Cartilaginous part of nasal framework is frequently involved in the atypical nasal cleft in the form of notch in alar cartilage or in form of anaplasia or hypoplasia. Restoring normal esthetic anatomy usually needs cartilage graft; the costal cartilage was the donor in eight cases and conchal cartilage was the donor in two cases. In most cases, the atypical nasal cleft was associated with short columella. The columellar lengthening is performed either by V-Y flap alone in two cases or V-Y flap with cartilage graft in six cases or composite conchal graft in three cases [Table 3].
The management of associated craniofacial anomalies is closely related to management of atypical nasal cleft. Hypertelorism management was performed by orbital translocation in three cases and by medialization of orbital wall in one case. During hypertelorism repair, medialization of nasal bone is performed. Correction of frontoethmoidal meningocele is performed, corrected in same operation of correction of nasal cleft by double approach, intracranial and nasal approaches; bone grafts are used to close the defect and for excision of the expanded skin. Cleft lip repair during repair of median cleft lip columellar lengthening is performed and labial flaps are used to close nasal floor.
The esthetic outcome of surgical interference was assessed by patient's satisfaction and doctor's satisfaction. According to patient's satisfaction, 17.6% had excellent result, 70.6% had good results, and 11.7% had poor results. According to doctor's satisfaction, 17.6% had excellent results, 58.8% had good results, and 17.6% had poor result.
| Conclusion|| |
On the basis of this study, the congenital nasal clefts have variable patterns ranging from simple to complex deformities. To restore normal esthetic anatomy of the nose, this needs proper evaluation of the deformity and accordingly planning the management. We come to a treatment algorithm to facilitate decision of plan of management for each pattern of congenital nasal clefts.
