Posteroinferior septal defect due to vomeral malformation.

PURPOSE: Vomeral malformation may lead to a posteroinferior septal defect (PISD). It is usually found incidentally, without any characteristic symptoms. The purpose of this study was to evaluate its clinical implications. METHODS: In this study, we included 18 patients with PISD after reviewing paranasal sinus computed tomography scans and medical records of 2655 patients. We evaluated the shape of the hard palate and measured the distances between the anterior nasal spine (A), the posterior end of the hard palate (P), the posterior point of the vomer fused with the palate (V), the lowest margin of the vomer at P (H), and the apex of the V-notch (N). RESULTS: None of the PISD patients had a normal posterior nasal spine (PNS). Six patients lacked a PNS or had a mild depression (type 1 palate), and 12 had a V-notch (type 2 palate). The mean A-P, P-H, and P-V distances were 44.5 mm, 15.3 mm, and 12.4 mm, respectively. The average P-N distance in patients with type 2 palate was 7.3 mm. There were no statistically significant differences between the types of palates in A-P, P-H, or P-V distances. In patients with type 2 palate, there was a significant correlation between P-V and P-N distances (r = 0.664, p = 0.019). CONCLUSIONS: PISD due to vomeral malformations was identified in 0.7% of the cases in this study. None of the subjects had a normal PNS, which suggests that the development of the vomer is closely related to that of the hard palate.

Congenital Vomer Defect Incidentally Detected on Preoperative Evaluation for Nasal Septoplasty and Turbinoplasty.

A perforation in posterioinferior portion of nasal septum is rare and caused by vomeral defect. We report a case of 56-year-old man who had a vomer defect, which was detected incidentally during preoperative evaluation of nasal septoplasty and turbinoplasty. The patient had a surgery of septoplasty and bilateral turbinoplasty under general anesthesia. There was no septal mucosal tear or defect during septoplasty and turbinoplasty. When the patient who has vomeral defect with nasal obstruction is planned for septoplasty and turbinoplasty, the surgery should be performed carefully to protect the mucosa.

[Congenital vomer agenesis]. / Dogustan vomer yoklugu.

Congenital vomer agenesis is a very rare condition. Usually, it is discovered incidentally. Nasal and otologic diseases accompany the cases. In this article, we report two cases of isolated congenital vomer agenesis who were admitted to our clinic with complaint of nasal obstruction. On endoscopic examination, deviated septum and inferior turbinate hypertrophy were observed in both patients. One patient was performed septoplasty, inferior turbinate radiofrequency, and functional endoscopic sinus surgery. Other patient was advised follow-up since the patient did not consent to operation.

Bony defect of palate and vomer in submucous cleft palate patients.

The aim of this study was to visualize bony defects of the palate and vomer in submucous cleft palate patients (SMCP) by three-dimensional (3D) computed tomography (CT) reconstruction and to classify the range of bony defects. Forty-eight consecutive non-operated SMCP patients were included. Diagnosis was based on the presence of at least one of three classical signs of SMCP: bifid uvula, a translucent zone in the midline of the soft palate, and a palpable 'V' notch on the posterior border of the bony palate. Patients were imaged using spiral CT. 3D reconstruction models were created of the palate and vomer. The sagittal extent of the bony cleft in SMCP was classified into four types: type I, no V-shaped hard palate cleft (8.3%); type II, cleft involving the partial palate (43.8%); type III, cleft involving the complete palate and extending to the incisive foramen (43.8%); type IV, cleft involving the complete palate and the alveolar bone (4.2%). The extent of the vomer defect was classified into three types: type A, vomer completely fused with the palate (8.3%); type B, vomer partially fused with the palate (43.8%); type C, vomer not fused with the palate up to the incisive foramen (47.9%). Significant variability in hard palate defects in SMCP is the rule rather than the exception. The association of velopharyngeal insufficiency with anatomical malformations may be complex.

Reconstruction of congenital vomeral bone defect using the outer table of the skull.

A congenital nasal septal defect involving vomeral bone is a rare nasal anomaly, and few reconstructed cases have been reported. Reconstruction of the nasal septum using the outer table of skull to allow the use of glasses was performed. The patient's postoperative course was uneventful, and the patient was discharged on the tenth postoperative day. A transferred bone remains and shows no deviation to the right or left in the ninth postoperative month. The tubercle of the nasal part remains, and the patient is satisfied with the cosmetic result 9 months postoperatively. The timing of the operation and the surgical procedure are discussed.

Vomer aplasia in a patient carrying a de novo mutation of the TP63 gene (3q27).

The congenital vomer defect (CVD) is a rare and still partially unknown condition. Only few cases have been reported in the international literature and the large majority of them appeared to be isolated. We report a case of CVD detected in a 7-year-old girl affected by ectodermal dysplasia clefting syndrome caused by a mutation of the TP63 gene.

Exceptional isolated cleft of the hard palate.

We describe an extremely rare type of isolated cleft of the hard palate, which extends the published classification of the Type III cleft.

Hereditary characteristic of isolated congenital vomer aplasia.

Malformation of the inner nose is often found in conjunction with different types of cleft palate or may be seen with severe and complex craniofacial anomalies. Among such malformations, however, isolated vomer aplasia is rarely reported in the literature. This study sets forth our findings that congenital vomeral defect of the nasal septum is an isolated disorder with hereditary characteristics. Between 2001 and 2009, nine cases of isolated congenital vomeral bone defect were detected on endoscopic examination of patients referred to our clinic with nasal and otologic complaints. The files of these patients were reviewed and vomer aplasia was identified as an isolated hereditary condition with concomitant sinonasal symptoms. The defect of the posteroinferior part of the nasal septum was defined as a genetic disease presenting with no significant medical problems. Chromosomal analysis of these patients may help to reveal the relationship of this anomaly with different malformations of the maxillofacial complex.

The absence of the vomer in the first and early second trimester of pregnancy - a new marker of trisomy 21 and trisomy 13.

PURPOSE: The aim of this study was to measure the two frontomaxillo-facial (FMF) angles: the FMF-vomer (FMF-v) and the FMF-palate (FMF-p), and to visualize the vomer in the 1(st) and early 2(nd) trimester, in order to ascertain whether they can be used as markers for trisomy 21 and trisomy 13. MATERIALS AND METHODS: A 2D ultrasound scan was performed in the 340 normal and 12 abnormal pregnancies, using the linear, convex and endovaginal probes. RESULTS: We visualized the FMF angles within 1 to 5 minutes in 253 (72 %) of cases by using the linear probe. FMF-v angle was significantly smaller that the FMF-p angle (79.8° vs. 89.7°, 71.5° vs. 84.5° for the two trimesters, respectively), and that the value of both angles decreased in the second trimester. There was not one single case of trisomy in which vomer could be identified in the 1 (st) and early 2 (nd) trimester. The FMF-p angle failed to present difference between normal cases and the ones with trisomy (89.5°). There was not one single case of trisomy (21 or 13) in which vomer or FMF-v could be identified in the first or early second trimester. The diagnostic accuracy of vomer as a marker for trisomy was 0.985. CONCLUSION: If the vomer cannot be visualized in the 1 (st) and early 2 (nd) trimester, it is important to check the karyotype, and it is not necessary to measure the FMF-p angle. The high resolution probe (L 12 - 5 Mhz) enables easier assessment of the vomer.

Vertical excess of the premaxilla in bilateral cleft lip and palate patients: a protocol for treatment.

Bilateral cleft lip and palate patients may present a vertical excess of the premaxilla, which is a severe aesthetic and functional problem. Early surgical correction may lead to secondary growth impairment. We present a suggested protocol based on the severity of the vertical excess and on the age of the patient, which includes orthopedic, orthodontic, and surgical corrections. Patients are presented to elucidate each different approach.
