Congenital partial arhinia with no associated malformations

Congenital hyporhinia with associated malformations: Case report of a rare congenital anomaly

Congenital hyporhinia, also known as partial arhinia, is a very rare congenital abnormality of nasal embryogenesis with unknown etiology. It is commonly associated with other craniofacial anomalies which are thought to be caused by an absent or rudimentary nose. A 3-h-old neonate presented to our facility with hypoplastic nasal pyramid, hypertelorism, microcephaly, and micrognathia, a case of congenital hyporhinia with associated anomalies is presented and the embryology and literature review are discussed.

Concurrent arhinia and choanal atresia in a day old male kid

Arhinia is a congenital nasal developmental anomaly that is seldom reported in literature, and especially not reported in domestic animals. This report describes a case of concurrent occurrence of congenital arhinia and choanal atresia in a day-old male kid which had no external nares with the nasal bones fused together with the nasal processes of the premaxillae presententing as a conical shaped rhinal structure with a tapering rostral apex and an occluded nasal vestibule. A bilateral osseous choanal atresia was also seen at the pharynx. Additionally, craniofacial and brain anomalies presented in this condition with right lateral deviation of the face and the absence of olfactory apparatus including olfactory bulbs, tracts and nerves and a vestigial trigonum olfactorium were noted. This, to the best of our knowledge is the first report in the literature indexed in the Medline of concurrent occurrence of congenital arhinia and choanal atresia in a goat.

Reconstruction of Congenital Arhinia With Stereolithographic Modeling: Case Correlate and Literature Review

Complete congenital arhinia is a rare defect of embryogenesis leading to the absence of the external nose and airway. We report our novel multistaged reconstructive approach and literature review. Nasal methyl methacrylate prosthesis was created from a stereolithographic model for use as a temporary prosthesis and tissue expander. Lefort 1 with cannulization was utilized for midface advancement and airway formation. External framework was reconstructed with bilateral conchal bowl cartilage and rib osteocartilagenous grafts. Patient was pleased with the aesthetics and had safe decannulation with the ability to breathe through the nose and airway.

Isolated congenital absence of lower lateral cartilages: A four cases report

Background

Although isolated congenital absence of lower lateral cartilages are rare deformities, they deserve special attention of plastic surgeons performing rhinoplasty as these anomalies may pass unnoticed by the patient and the plastic surgeon; until confronting them during surgery.

Methods

From August 2017 to December 2017, four cases of segmental loss of lower lateral cartilages were discovered accidentally during open primary septorhinoplasty of a total series of 250 cases. They were unnoticed by the surgeon preoperatively and the patients were unaware of these problems cosmetically or functionally. There was no history of trauma, major infection or any intervention in all four patients. Reconstruction of lower lateral cartilages was done with septal cartilage graft as part of the septorhinoplasty procedure.

Results

All surgeries were uneventful postoperatively and all patients were satisfied with the results.

Conclusion

On examining the patients for the rhinoplasty, one should be aware of subtle signs that may signify an underlying deformity in order for the patient to be informed about the complexity of the technique and for the surgeon to be prepared for the requirement of surgery.
