Surgical Management of Facial Features of Robinow Syndrome: A Case Report.

ABSTRACT: BACKGROUND:Robinow Syndrome is an extremely rare genetic disorder characterised by abnormalities in head, face and external genitalia. This disorder exists in dominant pattern with moderate symptoms and recessive pattern with more physical and skeletal abnormalities. It was first introduced by Menihard Robinow in 1969. It was related to chromosome 9q22 ROR2 gene related to bone and cartilage growth aspects. CASE PRESENTATION:A 17-year-old Egyptian male presented to National Research Centre Orodental genetics Clinic with typical features of short stature and facial dysmorphism weighted 50 Kg and measured 150 cm height complaining of facial dis figurement. There was no significant prenatal history, and family history was negative for congenital disabilities and genetic disorders. Clinical examination revealed macrocephaly and special facial features as prominent forehead, deformed ear pinna, hypertelorism, flat nasal tongue tie, deficient malar bone, bow-shaped upper and lower lips and dimpled chin. Orally the patient suffered from tonetie, gingival hypertrophy and dental malalignment. The orthopantomogram showed multiple impacted teeth. The physical examination revealed that the patient had deformed spine, short limbs with ectrodactyly, micropenis & hypospadias. Surgical management included correction of midface deficiency with zygomatic augmentation, closed rhinoplasty for the broad nose, lips muscles release and tongue tie relief. The patient is currently undergoing orthodontic treatment for his teeth. CONCLUSION:Improvement of facial features and a good psychological impact on the patient and his family.

Project description:Objective: This communication is the first assessment of outcomes after surgical repair of cochlea-facial nerve dehiscence (CFD) in a series of patients. Pre- and post-operative quantitative measurement of validated survey instruments, symptoms, diagnostic findings and anonymous video descriptions of symptoms in a cohort of 16 patients with CFD and third window syndrome (TWS) symptoms were systematically studied. Study design: Observational analytic case-control study. Setting: Quaternary referral center. Patients: Group 1 had 8 patients (5 children and 3 adults) with CFD and TWS who underwent surgical management using a previously described round window reinforcement technique. Group 2 had 8 patients (2 children and 6 adults) with CFD who did not have surgical intervention. Interventions: The Dizziness Handicap Inventory (DHI) and Headache Impact Test (HIT-6) were administered pre-operatively and post-operatively. In addition, diagnostic findings of comprehensive audiometry, cervical vestibular evoked myogenic potential (cVEMP) thresholds and electrocochleography (ECoG) were studied. Symptoms before and after surgical intervention were compared. Main outcome measures: Pre- vs. post-operative DHI, HIT-6, and audiometric data were compared statistically. The thresholds and amplitudes for cVEMP in symptomatic ears, ears with cochlea-facial nerve dehiscence and ears without CFD were compared statistically. Results: There was a highly significant improvement in DHI and HIT-6 at pre- vs. post-operative (p < 0.0001 and p < 0.001, respectively). The age range was 12.8-52.9 years at the time of surgery (mean = 24.7 years). There were 6 females and 2 males. All 8 had a history of trauma before the onset of their symptoms. The mean cVEMP threshold was 75 dB nHL (SD 3.8) for the operated ear and 85.7 dB (SD 10.6) for the unoperated ear. In contrast to superior semicircular canal dehiscence, where most ears have abnormal ECoG findings suggestive of endolymphatic hydrops, only 1 of 8 operated CFD ears (1 of 16 ears) had an abnormal ECoG study. Conclusions: Overall there was a marked improvement in DHI, HIT-6 and symptoms post-operatively. Statistically significant reduction in cVEMP thresholds was observed in patients with radiographic evidence of CFD. Surgical management with round window reinforcement in patients with CFD was associated with improved symptoms and outcomes measures.
