Other specified congenital malformations of face and neck » General Q18.8


Sinus, fistula, medial cyst of face and neck:
Branchial defects.
Cranio-Facial Atypical Clets:
Tessier's atypical or oblique craniofacial clefts.: Fissures in the soft and osseous tissues which may not correspond with points or lines of craniofacial process fusion, resulting in defects being disembryological absurdities.
Facial asymmetry WITH Structural Defect:
Facial asymmetry with underlying structural defect.
Sinus, fistula, medial cyst of face and neck:
They seem to be remnants of branchial clefts. As ICD10 lacks a specific code, they are coded es OTHER ANOMALIES OF THE NECK [ Q18.8].
Cranio-Facial Atypical Clets:
Photo and texts from Prof. Antonio Richieri Costa.
Numbering of Types refers to the classification of Tessier.
Facial asymmetry WITH Structural Defect:
ICD10 lacks a specific code and it is coded as: Other specified congenital malformations of the face and neck [ Q18.8].

Patients are numbered from 1 to 20 from left to right and from upper to lower.
1. Patient 1 with cleft number zero with holoprosencephaly.
2 e 3. Patients 2 and 3 with cleft number zero with fronto-nasal dysplasia.
4. Patient 4 with cleft number 4 and dorsal-nasal encephalocele.
5. Patient 5 with cleft number 2 without other anomalies.
6. Patient 6 with cleft number 3 or naso-oro-ocular (possibly due to constriction bands).
7. Patient 7 with cleft number 4 or oro-ocular cleft (possibly due to constriction bands).
8. Patient 8 with cleft number 5 (possibly due to constriction bands).
9. Patient 9 with cleft number 6 (possibly due to constriction bands).
10. Patient 10 with cleft number 7 (oculo-auricular-vertebral spectrum).
11. Patient 11 with cleft number 8 (Treacher Collins syndrome, mandibulo-facial dysostosis).
12. Patient 12 with cleft number 9 involving the left orbit at the upper border of the lateral canthus (probably due to constriction bands).
13. Patient 13 with cleft number 10 involving the upper medial region of both orbits (probably due to constriction bands).
14. Patient 14 with cleft number 11 with displaced canthus of the left orbit and boné defect at the medial-dorsal of the left orbit.
15. Patient 15 with a large cleft number 12, extending obliquely and rostrally and involving the right orbit.
16. Patient 16 with two fronto-medial defects, in combination with a cleft number 2, that can be considered as a cleft type 13.
17. Patient 17 with a cleft number zero, associated with a median cleft number 14, involving the frontal region.
18 y 19. Patients 18 and 19 with a cleft number 30 at the median mandibular line.
20. Figure number 20 oral view of cleft type 30.
