Abstract
INTRODUCTION Spondyloenchondrodysplasia (SPENCD) is a rare autosomal recessive skeletal dysplasia caused by acid phosphates 5 gene mutation. SPENCD has multisystemic manifestations including enchondromas in the long bones or pelvis, skeletal anomalies, immune dysfunctions, and neurological impairments. Out of the wide spectrum of presentation in SPENCD, hearing loss is one of the least presented symptoms. CASE PRESENTATION Here we present a two-year-old female, who visited the otolaryngology clinic concerned about hearing and delayed speech. The patient was started on hearing aids, later was diagnosed with SPENCD by pedatrics department. After a discussion with the family, the patient underwent a bilateral cochlear implant for sensorineural hearing loss at the age of four, which went uneventfully. CLINICAL DISCUSSION Children with skeletal dysplasias have abnormal tympanometry indicating a higher likelihood of middle ear disease and conductive hearing loss. A result of a hearing screening program done in 2010 showed that 25 % of children with skeletal dysplasia have hearing loss at least in 1 ear, and 50 % of them had abnormal tympanometry featuring middle ear dysfunction. Uncontrolled immune system response in autoimmune diseases commonly causes bilateral SNHL. However, the exact defect, in this case, is still unknown if it is cochlear or central. CONCLUSION The objective of this report is to highlight the unusual presentation of profound sensorineural hearing loss in a pediatric case with SPENCD that was managed with cochlear implants.

Abstract
OBJECTIVE To investigate the prevalence of diagnosed Eustachian tube dysfunction and related otologic diagnoses among children with achondroplasia as compared to a control population. METHODS The TriNetX Analytics Network, a federated health research network that aggregates the de-identified electronic health record data of over 78 million patients across the United States, was queried for patients 18 years old or younger with achondroplasia. Patients in this group with any occurrence of diagnosed Eustachian tube dysfunction or specified otologic diagnoses were recorded and reported. RESULTS Out of 2,195 patients 18 years old or younger with diagnosed achondroplasia, 379 (17.27%, 95% CI: 15.71-18.91) had a diagnosis of Eustachian tube dysfunction with an 8.65 (95% CI: 7.89-9.48) times higher risk than children without achondroplasia (n = 12,818,655). Children with achondroplasia also had higher risks for diagnosed otitis media (RR: 2.21), tympanic membrane retraction (RR: 7.29), middle ear cholesteatoma (RR: 6.35), cleft palate (RR: 12.24), conductive hearing loss (RR: 12.15), and tympanostomy tube placement (RR: 9.71). Each increased risk was maintained when cleft palate patients were removed from the achondroplasia group. CONCLUSION Children with achondroplasia are at a significantly higher risk for diagnosed Eustachian tube dysfunction and related middle ear diagnoses. Atypical craniofacial anatomy among children with achondroplasia may play a role in the dysfunction of the Eustachian tube and thus the observed epidemiology of otologic conditions. Children with achondroplasia should be monitored closely for middle ear conditions and the constellation of symptoms related to a dysfunctional Eustachian tube.

Abstract
Achondroplasia, the most common skeletal dysplasia, is characterized by a variety of medical, functional and psychosocial challenges across the lifespan. The condition is caused by a common, recurring, gain-of-function mutation in FGFR3, the gene that encodes fibroblast growth factor receptor 3. This mutation leads to impaired endochondral ossification of the human skeleton. The clinical and radiographic hallmarks of achondroplasia make accurate diagnosis possible in most patients. However, marked variability exists in the clinical care pathways and protocols practised by clinicians who manage children and adults with this condition. A group of 55 international experts from 16 countries and 5 continents have developed consensus statements and recommendations that aim to capture the key challenges and optimal management of achondroplasia across each major life stage and sub-specialty area, using a modified Delphi process. The primary purpose of this first International Consensus Statement is to facilitate the improvement and standardization of care for children and adults with achondroplasia worldwide in order to optimize their clinical outcomes and quality of life.

Abstract
Background Achondroplasia is the most common form of disproportionate skeletal dysplasia. The condition is caused by a mutation in the FGFR3 gene, affecting endochondral bone growth, including the craniofacial anatomy. Recurrent otitis media infections, chronic middle ear effusion, and hearing loss are common in children with achondroplasia, but few studies have investigated hearing loss in adults with this condition. Objectives This population-based study investigated the prevalence, severity, and type of hearing loss in Norwegian adults with achondroplasia. Methods We collected data on 45 adults with genetically confirmed achondroplasia: 23 men and 22 women, aged 16–70 years. All participants underwent a comprehensive audiologic assessment, including medical history, pure-tone audiometry, speech audiometry, and impedance audiometry. According to the Global Burden of Disease classification, pure-tone average ≥ 20 decibel hearing level (dB HL) was considered clinically significant hearing loss. Results Insertion of ventilation tubes had been performed in 44% (20/45) of the participants, 49% (22/45) had a history of adenoidectomy, while 20% (9/45) used hearing aids. Hearing loss in at least one ear was found in 53% (24/45) of the participants; in 57% (13/23) of the men and 50% (11/22) of the women. In the youngest age group (age 16–44 years), 50% (14/28) had hearing loss, although predominantly mild (20–34 dB HL). An abnormal tympanometry (Type B or C) was found in 71% (32/45) of the participants. The majority (15/24) had conductive hearing loss, or a combination of conductive and sensorineural hearing loss (8/24). Conclusions Adults with achondroplasia are at increased risk of early hearing loss. Our findings underline the importance of a regular hearing assessment being part of standard care in achondroplasia, including adolescents and young adults. In adult patients diagnosed with hearing loss, an evaluation by an otolaryngologist should be considered, and the need for hearing aids, assistive listening devices, and workplace and educational accommodations should be discussed.

Otolaryngology Utilization in Patients With Achondroplasia: Results From the CLARITY Study. Laryngoscope 2021; 132:1548-1554. [PMID: 34708868 DOI: 10.1002/lary.29915] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 09/22/2021] [Accepted: 10/10/2021] [Indexed: 11/08/2022]
Abstract
OBJECTIVES/HYPOTHESIS To quantify otolaryngologic surgery utilization in patients with achondroplasia, and to identify any changes in utilization over the past four decades. STUDY DESIGN Retrospective cohort study. METHODS A retrospective cohort study of 1,374 patients with achondroplasia enrolled in the CLARITY retrospective cohort study at four centers of multi-specialty care for patients with achondroplasia. Otolaryngologic surgeries are presented by birth cohort decade. The main outcomes were number of primary and additional otolaryngologic procedures; age at surgery; likelihood of repeated surgery; temporal trends in surgical utilization. RESULTS In this cohort of 1,374 patients with achondroplasia, 620 (45.1%) had pharyngeal surgery at least once, 150 (10.9%) had pharyngeal surgery on more than one occasion, and patients who had adenoidectomy first were 2.68 times more likely to require a second pharyngeal surgery than those who had adenotonsillectomy. Seven hundred and seventy-nine (56.7%) had tympanostomy tubes placed at least once, and 447 (32.5%) had tympanostomy tubes placed more than one time. Age at first pharyngeal surgery decreased by 1.2 years per birth cohort decade, and age at tympanostomy tube placement decreased by 1.1 years per decade. CONCLUSIONS Patients with achondroplasia often require otolaryngologic surgery, particularly adenoidectomy and/or tonsillectomy as well as tympanostomy tube placement. Such surgery is performed now more frequently and at younger ages than in earlier decades. While otolaryngologic disease associated with achondroplasia is now recognized earlier and treated more frequently, long-term outcome studies are needed. LEVEL OF EVIDENCE 3 Laryngoscope, 2021.

Orphanet J Rare Dis 2021; 16:156. [PMID: 33827611 PMCID: PMC8028078 DOI: 10.1186/s13023-021-01792-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Accepted: 03/26/2021] [Indexed: 11/10/2022] Open
Abstract
Background Previous studies have found a high prevalence of obstructive sleep apnea (OSA) in children with achondroplasia, but clinical studies on this complication in adults with achondroplasia are lacking. Objectives This population-based, cross-sectional study investigated the prevalence, severity, and predictive factors of OSA in Norwegian adults with achondroplasia. Methods We collected clinical data on 49 participants. Participants without a preexisting diagnosis of OSA had an overnight sleep registration. OSA was defined as an apnea–hypopnea index (AHI) ≥ 5 plus characteristic clinical symptoms, or AHI ≥ 15. We used the Berlin Questionnaire to assess clinical symptoms of OSA. Results OSA was found in 59% (29/49) of the participants (95% confidence interval 44 to 73%), of whom 59% (17/29) had moderate to severe OSA (AHI ≥ 15), and 48% (14/29) were previously undiagnosed. Variables predictive of OSA were: excessive daytime sleepiness; unrested sleep; loud snoring; observed nocturnal breathing stops; hypertension; age > 40 years; and BMI > 30 kg/m2. Conclusion OSA was highly prevalent in Norwegian adults with achondroplasia, which we believe is representative of this population worldwide. Follow-up of adults with achondroplasia should include assessment of symptoms and signs of OSA, with a low threshold for conducting an overnight sleep registration if findings suggestive of OSA are present.

Abstract
Background Recognition and appropriate management of the craniofacial manifestations of patients with skeletal dysplasia are challenging, due to the rarity of these conditions, and dearth of literature to support evidence-based clinical decision making. Methods Using the Delphi method, an international, multi-disciplinary group of individuals, with significant experience in the care of patients with skeletal dysplasia, convened to develop multi-disciplinary, best practice guidelines in the management of craniofacial aspects of these patients. Results After a comprehensive literature review, 23 initial statements were generated and critically discussed, with subsequent development of a list of 22 best practice guidelines after a second round voting. Conclusions The guidelines are presented and discussed to provide context and assistance for clinicians in their decision making in this important and challenging component of care for patients with skeletal dysplasia, in order standardize care and improve outcomes.

Abstract
Achondroplasia is the most common of the skeletal dysplasias that result in marked short stature (dwarfism). Although its clinical and radiologic phenotype has been described for more than 50 years, there is still a great deal to be learned about the medical issues that arise secondary to this diagnosis, the manner in which these are best diagnosed and addressed, and whether preventive strategies can ameliorate the problems that can compromise the health and well being of affected individuals. This review provides both an updated discussion of the care needs of those with achondroplasia and an exploration of the limits of evidence that is available regarding care recommendations, controversies that are currently present, and the many areas of ignorance that remain.

Abstract
OBJECTIVE Otitis media with effusion (OME) is a condition in which fluid is retained in the middle ear cavity. The association between endocrine disorders and OME has not yet been determined. This study aimed to investigate the presence of OME in children diagnosed with an endocrine disease and the relationship between these two conditions. METHODS The study was conducted on 918 pediatric patients (440 boys, 478 girls; mean age: 8.40, range 3-15 years) and 158 healthy controls (76 boys, 79 girls; mean age: 8.31, range 3-15 years). All children underwent an ear examination and a tympanometry performed by an otorhinolaryngologist. Tympanometry results were used to diagnose OME. RESULTS OME was detected in 205 (22.3%) of 918 patients and in 19 (12.0%) of 158 subjects in the control group. The difference in frequency of OME between the two groups was statistically significant (p=0.003). CONCLUSION The results of the study reveal that there may be a tendency towards the occurrence of OME in pediatric endocrinology patients.

Abstract
BACKGROUND Children with achondroplasia often have breathing problems, especially during sleep. The most important treatments are adenotonsillectomy (for treating upper obstruction) and/or neurosurgery (for resolving cervicomedullar junction stenosis). DATA SOURCES We reviewed the scientific literature on polysomnographic investigations which assessed the severity of respiratory disorders during sleep. RESULTS Recent findings have highlighted the importance of clinical investigations in patients with achondroplasia, differentiating between those that look for neurological patterns and those that look for respiratory problems during sleep. In particular, magnetic resonance imaging (MRI) and somatosensory evoked potentials are the main tools to evaluate necessary neurosurgery and over myelopathy, respectively. CONCLUSIONS The use of polysomnography enables clinicians to identify children with upper airway obstruction and to quantify disease severity; it is not suitable for MRI and/or neurosurgery considerations.

Abstract
Acute otitis media (AOM) is a common disease of childhood. AOM is most appropriately diagnosed by careful otoscopy with an understanding of clinical signs and symptoms. The distinction between AOM and chronic otitis media with effusion should be emphasized. Treatment should include pain management, and initial antibiotic treatment should be given to those most likely to benefit, including young children, children with severe symptoms, and those with otorrhea and/or bilateral AOM. Tympanostomy tube placement may be helpful for those who experience frequent episodes of AOM or fail medical therapy. Recent practice guidelines may assist the clinician with such decisions.

Disrupted bone remodeling leads to cochlear overgrowth and hearing loss in a mouse model of fibrous dysplasia. PLoS One 2014; 9:e94989. [PMID: 24788917 PMCID: PMC4006800 DOI: 10.1371/journal.pone.0094989] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2014] [Accepted: 03/20/2014] [Indexed: 02/05/2023] Open
Abstract
Normal hearing requires exquisite cooperation between bony and sensorineural structures within the cochlea. For example, the inner ear secretes proteins such as osteoprotegrin (OPG) that can prevent cochlear bone remodeling. Accordingly, diseases that affect bone regulation can also result in hearing loss. Patients with fibrous dysplasia develop trabecular bone overgrowth resulting in hearing loss if the lesions affect the temporal bones. Unfortunately, the mechanisms responsible for this hearing loss, which could be sensorineural and/or conductive, remain unclear. In this study, we used a unique transgenic mouse model of increased Gs G-protein coupled receptor (GPCR) signaling induced by expression of an engineered receptor, Rs1, in osteoblastic cells. These ColI(2.3)+/Rs1+ mice showed dramatic bone lesions that histologically and radiologically resembled fibrous dysplasia. We found that ColI(2.3)+/Rs1+ mice showed progressive and severe conductive hearing loss. Ossicular chain impingement increased with the size and number of dysplastic lesions. While sensorineural structures were unaffected, ColI(2.3)+/Rs1+ cochleae had abnormally high osteoclast activity, together with elevated tartrate resistant acid phosphatase (TRAP) activity and receptor activator of nuclear factor kappa-B ligand (Rankl) mRNA expression. ColI(2.3)+/Rs1+ cochleae also showed decreased expression of Sclerostin (Sost), an antagonist of the Wnt signaling pathway that normally increases bone formation. The osteocyte canalicular networks of ColI(2.3)+/Rs1+ cochleae were disrupted and showed abnormal osteocyte morphology. The osteocytes in the ColI(2.3)+/Rs1+ cochleae showed increased expression of matrix metalloproteinase 13 (MMP-13) and TRAP, both of which can support osteocyte-mediated peri-lacunar remodeling. Thus, while the ossicular chain impingement is sufficient to account for the progressive hearing loss in fibrous dysplasia, the deregulation of bone remodeling extends to the cochlea as well. Our findings suggest that factors regulating bone remodeling, including peri-lacunar remodeling by osteocytes, may be useful targets for treating the bony overgrowths and hearing changes of fibrous dysplasia and other bony pathologies.
