ABSTRACT
Background: Endoscopic evaluation is essential for grading adenoid hypertrophy. Most existing systems are based on nasal endoscopic views (0° telescope) assessing choanal obstruction. However, in children or patients with narrow nasal cavities, oral endoscopic visualization with a 70° or 90° telescope can provide an alternative, clearer view. Objective: To propose a new oral endoscopic grading system of adenoid hypertrophy that is simple, visual, and correlates with the degree of choanal obstruction. Methods: Based on intraoral 70° or 90° endoscopic assessment of adenoids through the mouth, a four-grade system was developed according to the visible extent of obstruction of choana and torus tubarius. The grading can be applied both under topical or general anesthesia. Results: Arefin’s Oral Endoscopic Grading (AOEG) system demonstrates consistent visualization of the adenoid mass, torus tubarius, and choanal opening without nasal manipulation. It is reproducible and correlates well with the established nasoendoscopic percentage-based systems. Conclusion: Arefin’s Oral Endoscopic Grading offers a practical and patient-friendly approach, especially for pediatric or uncooperative patients, and may serve as a complementary or alternative classification method for research and surgical planning.

INTRODUCTION
Adenoid hypertrophy is a common cause of nasal obstruction, recurrent otitis media, and sleep-disordered breathing in children [1-3]. Accurate grading is crucial for diagnosis and treatment planning. Most existing grading systems—such as those proposed by Cassano (2003), Parikh (2006), and Clemens (1998)—are based on nasoendoscopic evaluation using a 0° telescope through the nasal cavity [1,4,5].
However, this approach is sometimes difficult in children due to nasal narrowness, septal deviation, or discomfort [6,7].
To overcome this limitation, visualization through the oral route using a 70° or 90° telescope provides a clear panoramic view of the adenoid pad, choana, and torus tubarius behind the soft palate [2,8].
This paper introduces a simple, reproducible system — Arefin’s Oral Endoscopic Grading (AOEG) — to describe adenoid hypertrophy based on oral endoscopic visualization.
METHODS
Arefin’s Oral Endoscopic Grading (AOEG) of Adenoid Hypertrophy
|
Grade |
Description (Oral Endoscopic View) |
Approx. Choanal Obstruction |
|
I |
Small adenoid tissue visible behind soft palate; does not touch choana or torus tubarius. |
<25% |
|
II |
Adenoid tissue touches posterior choanal margin but not torus tubarius. |
25–50% |
|
III |
Adenoid pad covering choana and partially covering one or both torus tubarius. |
50–75% |
|
IV |
Massive adenoid pad completely obstructing choana and both torus tubarius, touching soft palate. |
>75% |

Figure 1. Arefin’s Oral Endoscopic Grading (AOEG) of Adenoid Hypertrophy — Oral endoscopic views (70°–90° telescope) showing progressive adenoidal enlargement behind the soft palate from Grade I (<25%) to Grade IV (>75%) obstruction of choana and torus tubarius. Landmarks: Ad = Adenoid pad; V = Vomer; ET = Eustachian tube opening.
DISCUSSION
Arefin’s Oral Endoscopic Grading provides a direct, comfortable, and accurate method of assessing adenoidal size, especially in situations where nasal endoscopy is difficult or contraindicated [3,7]. It allows a clear image of both choanae and Eustachian tube openings simultaneously.
Advantages include:
Clinical significance:
Grades III and IV strongly suggest surgical intervention (adenoidectomy ± tonsillectomy), while Grades I and II may be managed conservatively [3,13].
CONCLUSION
The Arefin’s Oral Endoscopic Grading (AOEG) system offers a novel, safe, and clinically applicable approach for evaluating adenoid hypertrophy via the oral route. This method complements existing nasal endoscopic grading systems and may improve preoperative evaluation, postoperative comparison, and documentation in both pediatric and adult populations.
Further validation through multicentric studies is recommended.
