The Role of Maxillary Osteotomy in the Treatment of Arhinia

Purpose

Arhinia is a very rare malformation, and only 41 cases are described in the literature. Given its rarity, there is no standardized surgical protocol. This article describes our preferred treatment, which underlines the importance of maxillary osteotomy for obtaining satisfactory results.

Methods

We observed 3 girls with arhinia, 2 of whom were treated by a 2-step surgical protocol. During the first phase, the patients underwent maxillary osteotomy with the creation of a new epithelium-lined nasal cavity. A skin expander was also placed in the forehead. During the second step, an external nose was created in both patients from the expanded forehead flap with local perinasal flaps and costochondral grafts.

Results

Both reconstructions were viable and esthetically acceptable. No internal nose restenosis was observed.

Conclusions

On the basis of our experience, maxillary osteotomy should be considered part of an integrated approach in treating arhinia.

Case Reports

Patient 1 was born in Morocco to healthy unrelated parents. At birth, she showed no signs of respiratory distress, but she had some difficulty feeding and required an orogastric tube for a few weeks. Her psychophysical development was normal when we first examined her at the age of 6 years. She showed all the typical signs of arhinia associated with a minor form of Treacher Collins syndrome: the external nose, nasal cavity, and paranasal sinuses were absent. In addition, the maxilla was

Discussion

There are 2 goals in the treatment of arhinia. The first is to manage any peripartum complications. The literature includes some reports of neonatal respiratory distress accompanying this disease. This concurs with the dogma of newborns being obligatory nasal breathers. Remarkably, none of our 3 patients showed signs of respiratory distress at birth. This, along with other reports,11, 12, 13 should lead to reconsideration of the principle stating that newborns are absolutely required to breathe

    Multiple procedures of nasal reconstruction refinements can be necessary during the development, based on the child's growth. Free flaps (e.g. femoral medial condyle flap or iliac crest flap) can be also considered, especially during the patient's growth [35,70,71]. Treatment of congenital nasal septum deviation is, above all, medical.
