Effect of Maxillary Morphology on Eustachian Tube Function in Children with Adenoid Hypertrophy: An Observation Study

1. AIM: To determine association between change in maxillary morphology and Eustachian tube dysfunction (ETD) in children with adenoid hypertrophy (AH), in order to find the basis of ETD in this population

OBJECTIVES:

Primary objectives:

To correlate palatal arch morphology measures with Eustachian tube dysfunction in children with adenoid hypertrophy

To correlate cephalogram parameters with Eustachian dysfunction in children with adenoid hypertrophy

Secondary Objectives:

To correlate Pediatric Sleep Questionnaire with palate morphology and Eustachian tube dysfunction

BRIEF METHODOLOGY:

Number of patients - 50

Place of Study:

0. Dept of Otorhinolaryngology, AIIMS, New Delhi

CDER, AIIMS, New Delhi 2. Period of Study: 2 years (July 2024 to June 2026)

INCLUSION CRITERIA

• Age 7-14 years
• Patients with adenoid hypertrophy

(diagnosed clinically and lateral neck X

ray) 3. EXCLUSION CRITERIA

• Other causes of palatal arch morphology changes: history of thumb sucking, gross DNS (defined as septum in contact with lateral nasal wall)
• Patients with cleft palate
• Patients post surgery
• Patients with syndromic features
• Child uncooperative for taking dental

impression

• Unwilling to participate in the study

Study Design: Case control Study

Investigations: tympanometry, PA and lateral cephalograms, palate arch impression

Questionnaires-

Eustachian Tube Dysfunction Questionnaire (ETDQ-7)

Pediatric Sleep Questionnaire (PSQ)

Brief Methodology

• After fulfilling the inclusion criteria and taking informed written consent and after approval from ethics committee, the study will proceed.
• Patient will fill the questionnaires (ETDQ-7 and Pediatric Sleep Questionnaire) and undergo general and local examination.
• Patient will undergo Eustachian tube function test (tympanometry).
• Patient’s PA and lateral cephalograms will be taken
• Patient’s dental study model of maxilla will be obtained using alginate impression
• The PA and lateral cephalograms will be analysed for standard cephalometric parameters and transverse maxillary width (distance from jugal point to jugal point, and between upper first molars). The maxillary arch width, depth and palatal height will be measured from the palate arch impression.
• Data analysis
