ASSESMENT OF TONSIL VOLUME WITH ULTRASONOGRAPHY IN BOTH CHILDREN AND ADULTS

July 22, 2019 updated by: Erdem Mengi, Pamukkale University

ASSESSMENT OF TONSIL VOLUME WITH TRANSCERVICAL ULTRASONOGRAPHY IN BOTH CHILDREN AND ADULTS - A PROSPECTIVE CLINICAL RESEARCH

The tonsil volume is an important factor in the decision of the tonsillectomy operation. For this reason, it is important to evaluate the tonsil size before the surgery. Ultrasonography was used in a limited number of studies about tonsil tissue assessment and also those studies include only the pediatric population. In this study, we investigate the success of ultrasonography in adults additionally pediatric population as a contribution to literature.

Detailed Description

Tonsillectomy is a common procedure performed on both adults and children. Recurrent tonsillitis, snoring and obstructive sleep apnea is among the most important indications for this surgery. Tonsil volume, in addition to recurrent tonsillitis frequency, are both considered in deciding tonsillectomy operation. Moreover, recent studies showed a correlation between tonsil hypertrophy and tonsillitis frequency. For this reason, a reliable assessment of tonsil volume is crucial both during clinical follow-up and surgery decision.

Today, a number of clinical staging systems are used to assess tonsil volume; with 'Friedman Scale' and 'Brodsky Scale' being the most commonly used systems. Those staging systems employ physical examination and are graded on palatine tonsils' midline extension. In other words, clinical staging uses just the transverse length of tonsils and vertical length and depth are dismissed. In addition, other factors such as patient non-compliance, size of the tongue and tongue base, hyperactive gag reflex and trismus make a clinical assessment difficult. For those reasons, a correct clinical assessment of tonsil volume is not always conceivable.

Ultrasonography (USG) was used in a limited number of studies about tonsil tissue assessment despite high patient compliance, low cost and its non-radioactive nature. Also, those studies include only the pediatric population.In this study, we would like to assess the success of USG in objective measurement of tonsil volume in both pediatric and adult populations and comparison of those results with clinical findings

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

ultrasonographic tonsil volume
All measurements were done by the same radiologist with over 20 years of experience. GE LOGIQ E9 (GE Healthcare, Milwaukee, WI, USA) was used in USG examination. The patients were viewed using a 2-9 MHz linear probe from the submental region. The examination was done while the patient was in a supine position, with a neck support. Right tonsil measurement was done by turning the neck slightly to the upper left whereas left tonsil measurement was done by turning the neck slightly to the upper right. Tonsil volume was calculated with standard ultrasonography formula (height x length x thickness x 0.52) due to its ellipsoid shape.
Procedure: tonsillectomy
Tonsillectomy was performed under general anesthesia using cold dissection method.
Actual tonsil volume
Excised tonsil volumes were calculated by water replacement method.
